<VV> 66 Monza 110 PG engine - sounds like big problems

[Jedd Hebrink]

 Thanks JR,
I had the engine completely disassembled, the crank ground, and rebuilt it
with new bearings, cylinders, rods, pistons, etc.  Did nothing to the heads
except power wash them.  This project started a few months ago when the #3
rod cap broke and peeled over at 90 degrees.  I learned later that the spark
plug was blown out on that cylinder and had to use a helicoil insert.

I did not use plastigage when assembling.  I guess I should have, but I
though I was okay because I was using new .010 bearings to match the ground
crank and rods. 

The suggestion that it may be dirt in a carb is encouraging.  I will explore
that further tonight and let you know what I find.  I did not notice any
temp difference from one side to the other, but I will pick up a temp gauge
and see if they differ.

Thanks a lot for your advice.
Jedd

Hi Jedd,

I'm not sure what was done/not done on this engine.  Your recent work was
just on the tranny?

Your problem could be as simple as dirt in one carb so that the engine is
essentially running on 3 cylinders OR something serious in the engine like a
bearing (you used plastigage?).  I suspect the former since it occurred
after a stop.  That is typical - after a stop or a turn.

Is one side of the engine hotter than the other side?  That's a big clue. 
The roadside cure for this condition is to remove the air cleaner, rev the
engine from the engine end, when the rrrs are up place your hand over the
offending carb (cooler side of engine) till the engine nearly dies.  Repeat
3 or 4 times.  See if it idles OK now.

Over the winter, check out the fuel system and make everything nice and
clean from the tank to the carbs.

Later, JR
