Tired of leaning over the bumper and winch. Four bolts and it's off.
Now to see if I can lap the valve and make a seal. Taking valve spring off.
Bought me $11 in tools. Suction cup hand spinner and Permetex valve grinding compound.
A few minutes lapping and the seat looks good.
That vavle by the way is over 2" in diameter.
Now for the supreme test, and...No air bubbles Hoo Ra. Now that does have pressurized air into the intake port.
A little cleaning and it's done.
I talked to my engine builder and he said the problem with deleting the zinc from motor oils happened around 3 years ago.
I installed the cam and heads 4 years ago.
He also said that the instant you/I started using the non-zinc oil that the wear was started right then.
I'm guessing that modern cars have engines that address this problem, maybe lower spring pressures. Most cars and trucks don't run racing heads anyway.
It was a Comp Cam that I had.
And my engine builder told me today that they won't even warranty the cam without adding their additive to the oil since this problem arised.
Thinking that this will be a real problem for some.
Seems that the gas and oil companies are going so Green that it might just back lash.
Next I'll place order for new cam and lifters from Summit.
Here is the stuff that they told me to use to keep cam warranty. Part #CCA159 and here is the link.
If I were you I would add this stuff to your oil if your doing a cam change.
Read also what they have to say about the new oils, interesting. Hope this info saves someone from a costly rebuild.
