[Healeys] Oil

[Bob Spidell]

Don't know if you know it, Michael, but you 'started' a long thread on 
the Forum about this (Steve Gerow re-posted a link he got from you):

http://www.britishcarforum.com/bcf/showthread.php?105991-Very-interesting-very-long-blog-posting-racing-oil-and-zinc

This guy's research, while impressive, has been disputed here:

This is of major interest to me, as I'll be rebuilding my BJ8's engine 
in the near future.  I've run it on off-the-shelf dino 20W-50--Castrol, 
Chevron (mostly) and Valvoline--for almost 120K miles so it will be 
interesting to see what the internals look like now (also want to see 
what deposits, if any, the PCV valve has caused in the intake system).  
#2 has low compression and we'll see if cam lobe wear is the cause.

Agree with Chris on the cam lube.  I bought a bunch of GM EOS assembly 
lube way back when and I'm tempted to pour a bottle down the pushrod 
tubes before first startup.  Thoughts (of course, I'll use assembly lube 
on the cam and all moving surfaces)?

Also, I'm leaning towards buying a cam from Denis Welch, which they say 
is 'gun-drilled' which, I presume, means the cam is lubricated 
internally and supplies a stream of oil to the lobes. I'll probably also 
go with their bucket lifters which have a hole on the bottom to supply 
yet more oil to the lifter-lobe surfaces.

I'm interested in hearing any and all thoughts and experiences on engine 
assembly and break-in.  I'm going all-in on this rebuild--it'll be the 
last for this car (I hope)--and my dad wants a friend of his who owns a 
racing engine shop to do the major work ($$$).
