[Vwdiesel] Piston Ring questions

Mon Feb 11 12:06:04 PST 2013

Bryan.  I don't think so.  Used to be able to? Yes, as a set for one hole,
but never single rings unless you were at a motor shop that does a lot of
them, and has odds left over from needing a ONE of something from a set.
Now? maybe not so much... Here, for sure not.  At a big engine shop if there
are any left, maybe. Helps? maybe? lol.... Someone on the list might have an
accumulated spare, but that might be the only place you can get one these
days.

<Rant mode on>
Nick.  I've received a V8 block back from being dipped, punched and decked
that still had cam bearings in them when they came back to me. Ever heard of
cleaning out the holes where that oil flows... they were full, of stuff.
WTF? I'm getting tired of going to experts, paying the money, and still
having to be the expert on everything, or it turns up sour. I've had a shop
offer to finish hone a race engine block without having the pistons in their
hands to match the bores to. I have had cutter chatter so bad on one perkins
diesel head it had to go back, after they assembled the valves and called me
to pick it up. Not like they didn't have ample time to examine the drag it
across the cement floor finish.  So much for getting experts to do it and
save on some time...  I've had race engine "experts" finish assemble a set
of small block heads so that installed (and they had the cam lift specs),
there was .040" of coil bind using pricey parts (mine, swirl polished manley
SS valves, Isky springs, etc.) They "just put in 2 spacers because that's
what they usually need". Why do I check stuff?  lol... SO, it goes without
saying I now own all the valve micrometers, bore gauges, spring installed
height seat pressure testers... all that's left is a sunnen finishing hone,
an align bore, and head finisher and it could be a production shop on James'
farm, all because I like to race stock cars and to finish first, you first
have to finish...  There are no more experts it seems, or the actual experts
are so damn busy, it's tough to get this year's stuff finished by next year.
When everyone wants cheapest, good is hard to find, great is nearly
impossible.  Chicken or the egg question- did cars become throwaway because
there's nobody to work on them, or because there is nobody to work on them
they have become throwaway?
<Rant mode off> yeah right lol....

Can you buy just the #2 oil ring, you can only buy a set of rings, no?

I can relate to James statement below. Not a good thing and I thought the
shop was a quality shop for rebuilding diesels. VW wasn't in there
vocabulary I guess.
