Below is this years oil analysis. I changed from Amsoil 5W-30 to German Castrol 0W-30 and also included Lube Controlin the oil and Fuel Power in the fuel. The other major change was the removal of the Donaldson air filter and installation of a Vararam and K&N filter.
After about 3,000 miles I installed a VHP cam with Crane 1.8 roller rockers, new valve springs/hardened pushrods, guide plates, Katech timing chain and the GMPP timing chain damper. I also sealed the bottom of the front cover with silicone. The car was run another 1,000 miles prior to this oil sample.
I was hoping to get an unbiased look at how the Vararam and the K&N filter changed my silicon level from the Donaldson, but the results will now be skewed because of the front timing cover sealing. Overall, I think the results look very good, especially in light of the fact that many new parts had to wear in after they were installed.
Comments, insights?
