Zddp

[Ol'Scratch]

Howdy Folks!!...;
I was over on the AK-47 forum today, and in "General Discussion", they were talking about ZDDP (Zink in oil). They mentioned that ZDDP in motor oil (or lack of) can damage engines with "Flat Valve Tappets". They mentioned that in in 2004 all engines had roller lifters/roller cam conversion and the lack of Zink in the oil didn't cause damage to the cam lobes. Now my Vette is an "88" 35th anniversary edition... does it have flat valve tappets or the other type??....

Thanks
Fast Freddie

I'm no L98 expert but I did a part search for 1988 L98 lifters and they sure look like rollers to me.

Tuna is correct, factory converted to roller lifters back in 1987........................
