Ok looked up the bearings for my new engine and on ETKA there seems to be 3 kinds for each engine. They carry colour designations, Yellow/ summat/summat. Whats the difference, which ones should i be using & why? Tim ps, im as good as guessing as the next person, but id appresiate someone who knew.
I may be wrong but usually they list the standard as Yellow and then use other colour codes for oversized bearings. i.e Standard = Yellow .020 = Blue .030 = Green They are only examples, i'm not sure what colours mean what size.
Same thing with the cam bearings,either undersize or oversize.can come out of the factory either way.Gotta take em in and get em measured before sticking new cam in .
well the crank hasnt been reground so im thinking yellow stock thickness ones. the engine is a baby, can still see the honing marks where it hasnt fully broken in.
ER spoke to ivor searle parts dept yesterday and got a price for cam bearings then phoned vindis and got price from them? i own mk2 8v rocco gtx
There are no removable cam bearings, as I said - take a look at the head yourself. The cams came out of the factory at a standard size, and the head has bearing surfaces machined into it, again at a standard size. No oversizes or undersizes, or replaceable bearings from the factory.
That's more likely, but if you fitted a new set of caps you would need the whole head align bored......
New to vw engines an being a chef by trade and only having worked on mini engines need as much helpfull advice as poss.cheers.
Unless there's obvious signs of wear or scoring, there's rarely a problem with them. Just keep them in the right order when you take them off......
Thats not strictly true, Ive seen a VW head with camshaft bearings like small main bearings (like fords 1.8d head) and Ive seen some VW motorsport heads with needle roller bearings for the cam
You can have them fitted for shell bearings if they die, but they never came like that from the factory. I fancy those needle bearings, tho.......
