Timing Chain Replacement

[Giavano]

Hi,

I recently bought a 2010 BMW Mini Cooper S Convertible 6-speed manual and it died on me within the first 12 hours of owning it.

My local mechanic suggested that I purchase a new engine because the timing chain needs to be replaced in addition to the head gasket and 8 broken valves.

I am wondering if I can just purchase the parts or do I really need to get a new engine (which would be very expensive).

Second opinion please. Thanks.

The safest course of action is to replace the engine. If the bottom end is known to be in excellent condition, you may be able to get away with just a top-end rebuild and chain replacement, but you are taking a chance that there isn't more damage than is obvious, or that you are putting stress on an already-worn bottom end.

If you are going to do the work yourself, it might be worth just trying the top-end. If you are paying someone else to do the work, it likely is not worth the risk.
