Thread: It finally happened to me

Even though it required extra work on your part, At least you got some satisfaction on warrantied items.

What exactly happens when cam lobes get wiped? I've heard of it but luckily never had it happen (knock on wood). I sort of understand that the lifters scrub the lobe off, is it lack of lubrication, or what happens exactly?

BTW, sorry for your engine problem bud.

Sounds like ya did everything right ?????
I would suggest using the Valvoline VV851 20W50 , 2 cans of G.M. E05 and leave the inner valve springs off untill you have done your cam breakin for 30 minutes @ 2500 rpm,then go ahead and put the springs back on and run 500 miles before you change the oil. You can then go back to your regular valvoline 20w50 racing oil as that VV851 is a little pricey..... You didn't use the old lifters did ya ??? If you did thats probally why it failed...

Were the lifters easy to turn in the block? Some are tight, and don't turn, wiping out the cam in no time.

Don, it is my understanding that the lifter crown goes first, then takes out the cam lobe. There is a ton of offshore lifters coming into the marketplace that are soft. See my following post.
