Re: [T3] Leon's Engine Autopsie report ( mystery data)


Jim wrote ,

When you installed the cam did you check to see that it was the 
right size for your crank gear and case? Are you aware of the size 
differences and how to check and install them?

If your cam gear was a little too large, then this would cause huge 
loads on the gear teeth.

The missing air duct on your right side: Was that the aftermarket 
one that feeds the lower heat exchanger around your header 
exhaust, or did you mean the lower half of the duct that carries air 
forward from the fan housing to the cylinders?

Jim, 

 I have never heard of this, about cam gear to crank 
gear matching to case matching, was this some kind of mystery data 
not mentioned in the books ?

I figure if I have a dual releif case that is not 
from the 60's, it would use a dished cam . Crank 
gear and it's surounding parts are sold in 
catalogs as one size and cam with gear custom
manufactured or stock/cam reground setups are 
sold as one size fits all or am I wrong ? 
If this is a fact then I really goofed because 
I just put them in there.

On the air duct, this looked like the original
heavy German one that was modified to fit the 
the aftermarket header . The day before I fixed it
my dad reported lots of smoke coming from that bank of
pistons. He was on a Home Depot run with a full 
heavy load of stuff. The next day I installed 
an aluminum flexible tube. I was in Japan for two weeks 
and my dad told me it was running funny for two 
weeks, it is corrected now even thogh in pieces. 
was missing duct from fan assembly to heater box.
