<VV> Fwd: Back to Engine Shop

[Carlton Smith]

Just what does the noise sound like? Is it a faint ticking or a really loud
ticking? That could be valve seat or it could be a rocker nut backed out. I
am mentioning this because the new rocker nuts Clark's is selling ( which do
not look like the stock shaped nuts) did that to me last year right after a
fresh engine rebuild. The first time was in March 2011 within the first 30
minutes I drove on the new engine rebuild, the second time was in June while
I was on a trip. I emailed Clarks about the problem and they searched their
inventory and said they found quite a few that were defective. Clarks sent
me a new set which was nice of them, but I was too leery of that style nut
by then so I threw them in a box and bought a standard shaped set from Comp
Cams and replace the whole set on my engine. The Clarks nuts are crimped in
2 places into a oval on a thin shoulder where the standard nuts are crimped
in 3 equal places and have a solid shoulder.

Anyway when the first nut backed out the engine had the symptoms mentioned.
Loss of power and hard to keep running.

The compression variation, while being far beyond normal tolerance, could be
fresh rings not yet thoroughly seated.  Compression test is a pretty good
indicator that the valve seats are in place ... but there could be a loose
seat that has not yet dropped.  
Has the source of the 'strange noise' been determined?

OK, I did a compression test an hour ago with the following results: #1 -
145; #2 - 145; #3 - 155; #4 - 130; #5 - 155; #6 - 125. Looks to me like the
whole left bank is weak, with #s 2 & 4 being especially bad. Am I right? And
how bad? What does this say about the symptoms it's now exhibiting: running
very rough, stalling out at idle, oil pres/temp light on at near idle?

my engine and its assembly (I also had an enlarged spark plug hole, like
Josh, and traded that head with a fellow VVer who was willing to fix it for
his own use when needed.), the saga now continues. The car is painted and
has the new top on it. Enroute to the glass shop to have the windows
installed/adjusted, the engine began making a strange noise and wanting to
stall out at idle. The Temp/Press light also came on when running less than
about 1000-2000 rpms. A local mechanic believes it to be a failed camshaft
bearing based on how it sounds. At any rate, it's going onto a trailer Mon.
morning for the two-hour ride to the shop where it was last worked on and
assembled. Then it was out of the car and was never run before I installed
it and got it up and running. Time will tell if it gets fixed under warranty
or if I pay through the nose, again. I'll keep you posted.
