[TPR] The Good, the bad and the ugly . . .

[Asa Jay Laughton]

Just a few comments of my own making...

I was schooled recently that ring gap placement is mostly a myth, as  
they will typically "turn" some while running.  Truth or fiction?  I  
can't say.  That would be a long term research project on my part.   
Oh, but I -do- have an engine in the garage undergoing (long term)  
forensics.  I know I placed the gaps as spec'd in the Ford factory  
manual.  I should check to see how they come out.

I'd suppose if one cylinder didn't get honed properly, it might blow  
oil just as you have experienced.  It would be interesting to know if  
that cylinder had been properly cross-hatched prior to assembly, or if  
something more dastardly like improper ring-gap (too tight?)  
contribute to it.

The glyptol thing has me bugged.  I'm presuming parts of the internals  
were painted (or otherwise somehow "coated") with glyptol.  Is that  
true?  Do you see signs of it having flaked off in places?  I think  
this bring up an interesting question.

Should an engine have this treatment done?  For all my prior rebuilds,  
I've not done any kind of painting or glyptol to the internal areas.   
I've left it all bare metal, oiled it up sufficiently and built the  
engine.  A friend I know, currently has several spare Cleveland blocks  
in his garage (actually set up as a kind of wine rack).  They've been  
stripped, cleaned and coated with glyptol.  He figures he may or may  
not use them in the future.  But if they've been coated with glyptol  
on the interior will this cause a problem?

Which two cam lobes were missing?
I would venture it was one of the back cylinders... most likely the  
very back, like number 8.

Last... if you can... could you provide some photos?  You can load  
them to TPR or I'll take care of it for you. :)

Thanks,
Asa Jay
