[TR] Leaking Push Rod Tubes on TR4A engine?

[Ben Zwissler]

I've got about 700 miles on my TR4A after its rebuild.  I've been 
tracking down some oil leaks and it seems I've got oil leaking from the 
push rod tubes in the head.  I reached that conclusion after installing 
one of Justin Wagner's silicon valve cover gaskets and degreasing the 
head.   Oil reappeared only around the pushrod tubes.  Anyone have 
experience with this?  I had the head gone over by a machine shop - new 
valve guides, valve job, etc.  They cleaned it, but did not hot tank it 
due to a prior experience with the tubes dissolving.  When reassembling 
I did not add any sealant specifically on the tubes.  Overall, the 
engine's not a horrible leaker but I'd like it to be better.

Thanks for any advice.  Ben.....
