These are separate views of the same evidence. Frequency alone does not establish a fix, and these counts must not be added together.

Coverage and how to read this overview

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

15 eligible posts · 0 unverified posts · 1 discussions match the subject in their title or opening post.

POST 1 / ORIGINAL POSTEROriginal post

Another dead engine Hi,had my 2001 3.4 C2 for a couple years and thought it was ok.Mileage 91k Went for a quick run today.All ok and did about 20 miles.Stopped at workshop for 15 mins or so and left for a blast. 5 miles later while following a slow car about 50 noticed a slight rattle.Oil pressure had dropped slightly so stopped. Had my son tow me back with the Disco to my workshop. Started the engine briefly,definately bearings shot.Hopefully not to much damage caused. The race workshop I use for my other cars used to run a GT3 in Britcar so should be able to fix. Good excuse to get the Exige out again.Will let you know the results of the strip down. Mike

POST 2Original post

Could be a number of things and you won't know till you strip it. What do you mean by bearings shot?

POST 3 / ORIGINAL POSTEROriginal post

The engine is rattling like a tin can.

POST 5 / ORIGINAL POSTEROriginal post

Agree but sounded like the bottom end.Hopefully will get the engine out next week.

POST 6Original post

Could be a worn tappet? Did it do it on tick over then go when you revved the engine?

POST 7 / ORIGINAL POSTEROriginal post

Hi,no on start up it clattered so bad switched off immediately.Mike

POST 8Original post

Could well be the ims...mine sounded the same;managed to turn it off quickly enough to maintain the timing thereby avoiding total engine destruction! I genuinely hope you discover something less expensive?

POST 9 / ORIGINAL POSTEROriginal post

Hi spoke to Steve at the race workshop and he will drop the engine out in a couple weeks,doesn't think it will be a problem to do. Fingers crossed.

POST 10Original post

Drop the oil, check the filter and take the sump off. It will give you a good indication of possible issues.

POST 11 / ORIGINAL POSTEROriginal post

My engine finally let go a few months ago. Have been to busy to do anything about it ,so finally dropped the engine out and dropped it off at Hartech.Result knackered crank etc. Quote from Grant for partial rebuild with s/h crank,rod.Plan B with new liners etc & top end overhall.Plan C full rebuild to 3.7. So 3.7 it will be after reading the article in 911 & Porsche world. Hopefully it will be done before the end of the year. Mike.

POST 12Original post

Sorry to hear that. Was it the main bearings which went in the end? Do you know what mileage the engine was on? MC

POST 13Original post

Mike - as MC says, sorry to hear this. Please can i ask, if its OK with you - that you come back here and give us full and regular updates...?? Hope this all gets sorted for you m8 :thumb: Osh

POST 14Original post

As above. Sorry to hear. Watching with interest.

POST 15 / ORIGINAL POSTEROriginal post

Hi,it was a big end that went and did the rod & crank.With it stripped the bottom end was on last legs through wear.Top end looked ok but it was showing wear.Will try to update with some pictures. Mike.
