Hello all,
Just read an article on the oil thing. The problem is the Zinc and
Phosphorus that will kill the catalytic converter if the engine starts to burn
oil. A friend of mine and I just replaced the catalyst on his car for this
reason. They found that flat tappet engines with very high valve spring
rates can have problems. Stock or even a bit more engines just don't have a
problem. As I recall the oils made for diesel engines, such as Rotella, still
have these additives. For engines with roller cams and tappets it is
totally a non issue.

There have been some concerns posted latey about using todays oil in our
old
Roadsters AFTER they have been broken in. The concern was they were
missing
the correct kind of additive package to provide proper wear care for our
cars,
and that you needed to get a specific oil additive. I asked my engine guru
who is careful about debunking these kind of things. His response:
"Bullshit. This was started by a Nascar team (Joe Gibbs) who had a cam go
flat and decided it was the oil. What it probably was was excessive spring
pressure. None of my customers, nor anyone else in the industry have
reported
any problems related to excessive wear due to todays oil. I think it is
marketing BS to sell a product."
I continue to run Mobile 1 without concern.

Subject: [Roadsters] Break-in oil & assembly

There's been some threads on the assembly and break-in of "new" engines. I
noticed an ad from Comp Cams in the latest issue of Chevy High Performance
for a new break-in oil (*http://tinyurl.com/ygtkpxl*) they're now selling.
Looks like a great product to me.
They also offers assembly lube and spray. Knowing Comp's reputation this
stuff is worth using, IMHO.
