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.

POST 1 / ORIGINAL POSTEROriginal post

I think and am told my 996 engine has finally given up. Any ideas for best and cheapest recon or rebuild ??

POST 2Original post

Don't Autofarm do an upgrade/rebuild? Think there was a feature in one of the mags.

POST 3Original post

This months 911 & Porsche World has an article on it. (Follow up to one a couple of months back). What exactly does "given up" mean though? If it's not one of the issues addressed by the Autofarm mods, then we're looking at a different fix.

POST 4Original post

Oh dear that's going to cost a packet. What is wrong with it?

POST 5Original post

Hi, My 996 also needs an engine rebuild,there is a knocking sound at idel i took the car to autofarm and spoke to Nick who was very helpful,he said the cost would be approx £6k.I would recommend talking to autofarm. But as i only bought the car in Nov 05 i went back to the dealer who has said he will change the engine,after a long discussion just hope the the replacement is a good one.

POST 6Original post

I would try Tony Wright at www.wrightune.co.uk . Loads of experience with engine rebuilds. Those Autofarm upgrades seem awfully expensive to me. They make out that it is all their own technology, but the upgraded blocks are made by Perfect Bore in Andover - see www.perfectbore.com

You could always get one on eBay http://cgi.ebay.com/ebaymotors/ws/eBayISAPI.dll?ViewItem&item=8010559389 Or how about an upgrade ;-) http://cgi.ebay.com/ebaymotors/ws/eBayISAPI.dll?ViewItem&item=8037825025

POST 8Original post

Perhaps also worth speaking to Hartech (www.hartech.org), they rebuild engines too. What I thought was terminal engine failure turned out to be a broken valve spring, new engine not required!
