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.

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

1 acknowledgements have no verified action link; they do not establish a repair result.

Outcome without a verified action link

POST 1 / ORIGINAL POSTEROriginal post

Dear all, I've been offered this today and wondered if anyone could confirm that it originates from a 3.4 litre 996. I don't need it at the moment as the car is running well but its nice to have put aside just in case!! Cheers Gerry

POST 2Original post

I think the engine number should be on there somewhere. That would be the best way to know for sure. Other than that, I can only think of measuring the bore and stroke. A 3.4 is 96mm bore and 78mm stroke, and the 3.6 is 96mm bore and 82.2mm stroke. Of course, it could be a Boxster engine, but they are a different bore size. 2.5 and 2.7 are 85.5mm bore, and the 3.2 is 93mm bore.

POST 3 / ORIGINAL POSTEROriginal post

Cheers Richard, I will ask him to see if there is an engine number to enable me to positively identify it. Thanks Gerry

POST 4 / ORIGINAL POSTEROriginal post

Richard, My mate has sent these photographs to help determine the crankcases original source. It seems that it is definitely from a 996 although the engine serial number is difficult to read. Regards Gerry [/img]

POST 5Original post

It looks like it reads M96/04 661 113(?)72 to me, which would make it a 2001 3.4 engine. The /04 and 661 are clear enough, which are the engine type and series, indicating a 3.4 and 2001, so it should be fine.

POST 6 / ORIGINAL POSTEROriginal post

Cheers Richard He isn't giving it away at 600 quid but the cost of replacing all of these parts tops up at £7000 plus vat!!! I think I'll have to take a chance and buy it from him. Cheers Gerry

POST 7 / ORIGINAL POSTEROriginal post

Richard, My 996 is tiptronic, will that make any difference? Gerry

POST 8Original post

No difference, as the crankshaft is the same for both. Is it complete with intermediate shaft and chain drive? I ask because the intermediate shaft for the M96/04 engine is no longer available, so if the shaft bearing goes and the shaft is damaged, you probably won't be able to get one to match. Depending on the engine type of your car, it will have either the roller chain drive, or a Hika chain. The two are incompatible, so you can't mix and match. If your friends block has all the parts you should be OK though.

POST 9Original post

A mind of information as always Richard. Thanks Andy

POST 10 / ORIGINAL POSTEROriginal post

Hi Richard, Thanks for all of your advice. Sadly It doesn't have the IMS included which is a shame if they are unavailable. Gerry

Did you see the announcement of short block at 50% off prices from OPC? Only takes one minute 32 seconds to build too [ ] [link]https://www.youtube.com/watch?v=KsXeLv93J8w[/url]
