[T3] Vintage oil

IM happy to say I still have MY Pecker!


when I bought my Berg kit, they were losing cam's left and right, they had
to break all of them in by hand on a special machine for 24 hrs before
shipping the cam and lifters out to you, we didnt yet know that the zinc had
been removed.

I kept using the off the shelf oil in the Square for many year, ignorant of
what it was, or wasnt in this case.  When I peered up into the case about 10
years ago when the engine had about 110K on it, the cam was worn, not scored
but the lobe edges appeared rounded off some.  This cam however went thru
the Amzoil motor destruction and was about the only part that wasnt damaged,
and it had about 20K additional miles on it when it was put in this
otherwise new engine..

Now that being said, that engine went on to last to 165Kmi, which would have
been 185K or so on that cam with fairly stable valve adjustments.

So was it worn?  Yes, more worn that otherwise? cant say.  Did it "ruin" the
cam?  No, but then again if the lobes had worn down a bit that might have
explained some loss of power in late life.

For what its worth...

It's not something that most of us are willing to offer up our engines as
subjects for. I only started using a zinc additive about a year ago, but the

opinion seems to be that the residue from previous oils gives long lasting 
protection, so who knows.

I recall Gene Berg mentioning, many years ago, that they were seeing cam 
and lifer failures that they could not explain. They had found no
in old vs. new metalurgy, but I don't think zinc concerns had hit anyone
This was just the beginning of the catalytic converter introduction.

I thought the YouTube video was interesting, but it was a bit of an apples
oranges comparison: straight weight non-detergent vs. multi-weight 
detergent. It would have been more interesting if he'd had more intermediate

products to compare, or maybe all straight weight. I'd love to see some SD 
or SE straight weight thrown in there.

The comments were interesting. Most of them really didn't seem to get how 
mismatched, in the apples to oranges sense, the oils were, but I loved the 
guy who referred to the old steel spouts that we used to punch into the
can tops as a "pecker." I'd not heard that term before, but I thought it was

perfect. I finally gave up and recycled my "pecker" a few years ago.
