RE: Another cam bites the dust

[Steven Charette <stevec@xxxxxxxxxxxxxxxxxxxx>]

Definately - there are some zinc supplements available in small bottles to
prop up the newer oils.  Can't find the links right now but they are out
there.  Shell Rotella had zinc but I've heard that it's being/been phased
out too (although I have not verified this myself).

Seems like the long term cost of zinc additives will eventually make
"scrubbers" as expensive as rollers!  I haven't had a scrubber fail yet (I
know I'm tempting fate by actually typing that) but can't help but think the
extra cost of the roller setup will save money long term.

Subject: Another cam bites the dust

I spoke to a friend of mine lest night, and just a couple of starts after
changing to diesel oil, he has wiped his cam. The motor is a 400 punched and
stroked to a 451? i think, and it does have a ~.600" cam w/ solid
lifters...non-roller. He had the Valvoline VR Racing oil in it and changed
it to the diesel oil because he couldn't find the VR.
He has not driven the car since the change, just started it 2-3 times since
changing the oil. After the new oil, it started sounding funny.
He checked valve lash and one was really loose. He's going to switch over to
a roller setup so he doesn't have to screw with this oil mess anymore.

He called the cam manufacturer and they said they continue to have issues w/
the new oils, and the zinc in the diesel oils is going to be reduced even
more soon. Time to stock up in the VR when you can find it I guess!
