Buying a BMW N13B16A timing chain kit with crank gear starts with a repair decision, not a model badge. A listing that mentions 114i, 116i or 118i gives you a useful place to begin, but it cannot establish what is installed in your particular car or which components your workshop intends to replace. This guide focuses on the RunningRoo N13 package and the questions that separate a suitable order from an expensive interruption to a booked repair.
The RunningRoo N13B16A kit with crank gear and the corresponding RunningRoo eBay item were available when checked. The website describes a chain, tensioner, three rails and a crank gear. Before ordering, send your VIN, complete engine code and workshop’s OE references. Call 0425 890 125 for friendly support from an Australian-operated business in Blackburn, Melbourne. Local pickup is by appointment; ask about current stock and fast dispatch for your postcode.

Why this N13 purchase needs its own checklist
A buyer searching simply for a BMW timing chain can encounter several different engine families, packages and levels of repair. Even within a search result headed with the correct engine, one offer might include a crank gear while another includes camshaft adjusters. Price comparisons become misleading if the buyer assumes that every visible round component serves the same function or that the longest product title represents the most complete repair.
For this order, write the intended scope in plain English: a chain kit that includes the listed crank gear, with the suitability of existing camshaft adjusters and any other drive components decided by the technician. That statement helps both the supplier and the workshop understand the purchase. It also prevents a separate requirement, discovered during diagnosis, from disappearing into a vague instruction to supply a complete timing kit.
Keep the full product link with the workshop estimate. A screenshot is useful for recording what was advertised at the time, but it may omit options, description text or a later update. Referencing the exact website item and eBay item number gives RunningRoo a practical way to identify the offer you are discussing. Ask for written confirmation if the package description changes between quotation and payment.
The manufacturer diagram explains the scope question
BMW’s N13 technical training diagram, reproduced on ManualsLib, identifies a primary chain, a secondary chain, an oil-pump sprocket, a crankshaft sprocket and separate intake and exhaust VANOS components. It also identifies guides, a tensioning rail and a chain tensioner. This is manufacturer-issued architectural background, not a current installation procedure or an approval of an aftermarket kit.
The buying implication is straightforward: a one-chain package should not be described as replacing every chain-driven component shown in the engine diagram. Equally, including a crank gear does not mean including both VANOS adjusters. Ask the workshop to name each part it intends to renew and identify the required additional items separately. Keep the diagram’s component distinctions in mind without using it to invent a repair sequence, torque specification or interchange claim.
What the selected product actually lists
The website packing description is the starting point for discussing contents. It lists one chain, one tensioner, three rail pieces and one crank gear. The eBay item also identifies the crank-gear inclusion in its item specifics. These are seller descriptions of the selected package; they are not a substitute for checking the delivered box against the agreed order and the vehicle-specific requirements.
| Purchase checkpoint | What to establish | What it prevents |
|---|---|---|
| Chain and tensioner | Match the supplied references to the workshop request | Ordering from a general engine name alone |
| Three listed rails | Confirm all required rail positions are covered | Assuming one visible guide replaces the complete set |
| Crank gear | Confirm the exact supplied component and required reference | Confusing a crank component with a cam adjuster |
| VANOS components | Record whether any are required separately | Expecting unlisted adjusters inside the box |
| Secondary drive requirements | Ask the technician to define the inspection and repair scope | Calling a one-chain package a whole-engine overhaul |
| Sealing parts and fasteners | Obtain a separate list where required | Discovering omissions after the vehicle is dismantled |
Do not treat the kit’s internal supplier codes as BMW OE numbers. A supplier can use its own identifiers to distinguish components in a package. The workshop still needs the correct original reference or a properly verified replacement cross-reference for the installed engine. Photographs can support that discussion, but appearance alone should not decide compatibility.
Build an identification record before comparing prices
Start with a readable VIN and the actual engine identification supplied by the workshop. Include the build information and any known replacement-engine history. If the engine has been changed, explain that early rather than letting everyone work from the original registration description. The vehicle identity and installed engine identity need to be reconciled before the order is treated as confirmed.
Then add the complete OE references requested by the technician. Keep suffixes, leading zeros and annotations intact. If you receive two alternative references, ask what makes the choice different rather than selecting whichever number is easier to find online. A supersession, application boundary or different repair scope needs a documented answer from someone with the appropriate catalogue information.
Finally, record who has approved the selection. An owner, supplier and workshop may each hold part of the information, but a successful order needs those pieces joined together. The owner can provide the VIN and repair history; RunningRoo can identify the offered package; the workshop can confirm the technical requirement. Avoid interpreting a general product enquiry as a completed diagnosis or a guarantee that every listed model uses identical parts.
Keep diagnosis separate from the shopping basket
If your reason for searching is a noise, warning or drivability concern, give the workshop a factual description of what you noticed. Record when it happened, whether the car was already warm, and whether any recent work preceded it. A short recording can help explain the complaint, but the recording should accompany an assessment request rather than become your own verdict that a chain kit is needed.
Ask the technician to explain which findings justify the proposed repair and which uncertainties remain. You do not need to request a particular test merely because it appears in an online discussion. The workshop should choose the diagnostic process from the correct service information and the vehicle’s condition. Request a written distinction between confirmed replacement items and parts that will only be assessed after access is obtained.
That distinction matters when buying a package with a crank gear. The presence of a gear in the offer does not establish that it has failed in your car, and a kit cannot promise to resolve every complaint associated with engine timing. Order against the agreed repair scope. If that scope changes, pause the purchasing decision long enough to check whether the selected package still makes sense.
A practical way to compare two quotations
Put the two quotations side by side and compare the included parts before comparing the totals. One may include the same chain package but omit the additional items or labour necessary for the planned job. Another may include extra work that your workshop has not recommended. Ask each provider to explain the difference using actual component descriptions, not just the word complete.
Separate parts supply, fitting labour, diagnosis and any conditional work. This gives you a clearer view of what is fixed and what may change after inspection. Request the workshop’s process for contacting you before additional costs are incurred. A modestly priced package can still be the wrong purchase if it does not match the diagnosis, while an expensive package is not automatically more appropriate.
You can review the current N13 product description alongside the live eBay offer, then send both to your mechanic. For a contents or collection enquiry, phone 0425 890 125. RunningRoo offers Melbourne local pickup by appointment and friendly Australian support; confirm stock allocation and the available dispatch service before coordinating a workshop booking.
Plan the handover between supplier and workshop
Decide where the parcel will go and who will check it. If the workshop receives customer-supplied parts, ask about its acceptance process before placing the order. Some jobs benefit from the parts arriving for inspection before the vehicle is taken out of service. Agree on the timing with the workshop rather than assuming that an expected delivery date is the same as a confirmed fitting appointment.
Provide a contact name and order reference with the parcel. Keep the packaging, labels and invoice until the workshop confirms the supplied items against its requirement. If a discrepancy is found, clear photographs of the label and affected component are more useful than a general statement that the kit looks different. Contact the supplier before the part is modified or fitted so the issue can be assessed properly.
For Blackburn pickup, make an appointment and confirm which order is being collected. If somebody else collects it, give them the order reference and the agreed collection details. Fast dispatch can help an organised repair, but travel time, carrier estimates and workshop availability remain separate arrangements. Check the current offer rather than relying on an old banner or another customer’s delivery experience.
An example of a well-defined N13 enquiry
Imagine an owner whose workshop has already identified an N13B16A and prepared a list of replacement references. The enquiry should explain that the workshop is considering the selected chain-and-crank-gear package, attach the VIN and engine information, and ask RunningRoo to confirm the supplied contents against that list. This is an illustrative purchasing example, not a report of a diagnosed customer vehicle.
If the workshop subsequently adds a camshaft adjuster, the owner should request a revised parts list rather than assume that the original package now covers it. If the workshop removes an item from its recommendation, the owner should likewise revisit the quote before buying. A clear revision trail keeps the purchase connected to the repair decision and helps avoid duplicate orders.
For an older car with incomplete history, be explicit about missing information. Ask the technician to resolve the identification issue and explain whether any previous work affects the parts request. There is no benefit in disguising uncertainty with a confident model-year guess. A supplier can give more useful support when the enquiry states exactly what has been verified and what still needs checking.

Frequently asked questions
Does this kit fit every BMW 116i or 118i?
Do not order on the badge alone. This guide concerns the selected N13B16A listing, and fitment needs the VIN, installed engine identity and appropriate OE references. Ask for confirmation of your particular application. A broad model list is a search aid, not proof that all cars carrying that badge share the same timing parts.
Are both VANOS gears included?
The selected website description lists a chain, tensioner, three rails and a crank gear. It does not list an intake-and-exhaust VANOS pair as part of that package. If the workshop requests adjusters, obtain a separate confirmed supply plan. Do not use the editorial cover or an engine diagram as a packing list.
Does the crank gear remove the need to inspect other parts?
That is a technical decision for the workshop, not something established by the purchase description. Ask which components are included in its assessment and how any additional findings will be reported. A package can satisfy an agreed list of parts without representing every item that might require attention in an individual engine.
Is there a mileage at which I should automatically buy this kit?
This article does not set a replacement interval. Have the workshop consult current BMW information for the vehicle and assess its condition and history. Do not convert an online mileage example, a training diagram or another owner’s repair into a universal instruction to replace your own timing components.
Can RunningRoo diagnose my car from a video?
A recording can help communicate a concern, but product support does not replace professional vehicle diagnosis. Share the workshop’s findings and required references when asking about this package. Keep the question focused on whether the offered parts match the confirmed requirement, while the technician remains responsible for the repair recommendation.
Can I collect in Melbourne or arrange delivery?
Contact RunningRoo to confirm stock and arrange Blackburn pickup by appointment, or ask about fast dispatch to your delivery address. Check current terms and timing before committing the car to a workshop schedule. Australian-operated support is available to help you identify the correct listing and clarify the order details.
Make the next step a confirmed parts request
The useful outcome is not simply a basket containing something labelled N13. It is an order that your workshop can connect to an identified engine, a documented diagnosis and a clearly defined set of replacement parts. Keep the crank gear, camshaft adjusters and any secondary-drive requirements distinct in that discussion, and resolve missing references before payment.
Open the RunningRoo N13B16A timing chain kit, compare the matching eBay listing, and call 0425 890 125 with your VIN, engine code and OE list. RunningRoo’s friendly Melbourne team can help with current product information, appointment-based local pickup and fast dispatch arrangements, so your purchase supports the repair your vehicle actually needs.
