Suggestion

You can use race engine specs for similar sized cams and aluminum bores, or just common since and measure known good m96 cam and bore, or use the measurement from a m96 with no visible wear and correct "matching caps"...

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.

POST 1 / ORIGINAL POSTEROriginal post

What should I think of this.... some shady mechanic has had his hands on this: - here's bank 2 cam bearing caps:

POST 2Original post

Oh, that's not good. Possibly careless, ham-handed, or misinformed about the importance of keeping the original parts together. More likely incompetent than shady.

POST 3Original post

Len Hoffman can match the cap to the head and re-stamp the matching numbers.. or if you have the skillz and are handy with micrometers/dial bore guages you can do a precision match and re-stamp your self.. If the cap is too loose you can file the mating surface on a flat file untill the fit is correct, or if too tight you can get shimstock in 0.001" 0.002" 0.003" thickness and shim to correct clearance You don't always need a boring machine or CNC to get precision fit, in fact even the machines are " hand verified" for precision fit..

POST 4Original post

Did u check to see if it belongs on the other head and a bad mechanic switched them? Might be a dumb sugestion because i never looked to see how that stuff was labeled/stamped. I thought tge heads did have different numbers?

POST 5 / ORIGINAL POSTEROriginal post

Quotes source post: 18274816

Are there official specs for camshaft and bore size?

POST 6 / ORIGINAL POSTEROriginal post

Quotes source post: 18274991

Those cam bearing caps on Bank 1 are correct and matching what is stamped on case.

POST 7Original post

Quotes source post: 18275844

Porsche produces no such specs... They expect/want you to just buy a new one.. You can use race engine specs for similar sized cams and aluminum bores, or just common since and measure known good m96 cam and bore, or use the measurement from a m96 with no visible wear and correct "matching caps"... The real key to it all is how well you can use precision micrometers and dial bore gauges, the precision of the instruments is really in the "hands" of the user..

POST 8Original post

^^^^ So you think you know as much as Skip? That is a catchy logo mister!

POST 9Original post

If I had to guess, just based on the fact that @UIDS has coughed up the money to be a site sponsor, the account is legit and that is probably Skip's partner.

Why pass up a legit opportunity to poke fun at George or Skip? And you know I want to see some merch with that logo. Can never have too many coffee mugs.

Yes, it's me... I created/payed for that account way back in February 6 months ago... I do forget that I even have it being old an all, and forget to use it... @hatchetf15 Yes that Logo would make a very nice coffee cup ....
