Flat tappet cam install considered a risk?

[BlackBandit]

BlackBandit ....did you continue to use EOS or Rotella T or any other suplement with Zinc with ALL of your oil changes before the lobe wiped?

Anyone hear of a cryo'd cam wiping?

No I did not continue to use the EOS.

Any one wipe a lobe while using a Zinc oil additive?

Any one wipe a lobe while using the Zinc additive?
(assuming proper break-in)

or with a cryo'd cam/lifters?

My condolances to all those with the damaged motors.

New Rotella Zinc content?

The maximum Zinc (ZDDP) content allowed in the new standard for Diesel oil is 1200 parts per million (.0012%). This standard was effective in January 2007. Does anyone know the actual Zinc content of the new Rotella?

quote from 87GN_70GS

Valvoline Synth Oil Treatment (VSOT) and CD-2 SLOB (Street Legal Oil Booster) have zinc in them at .17% and .48% respectively. The best part is I bought SLOB at Big Lots for $1.

sounds alot better than .0012%

an additive may be the best way to go rather than an oil that comes with the zinc in it.

i found this
continue with diesel engine oil?
a few posts down is the PPM of ingrediants in SLOB / CD-2

Any one wipe a lobe while using an oil additive or Rotella T?

Check Here should have the new numbers on Zinc
Oils: What oil do I use in my aircooled Porsche or VW?
Looks like it was updated 2/27/2007
Lately I have been adding STP to the Rotella

It's just a typo; 1200 ppm = 0.12 %
