Subject: Re: Is this the point where.................... by CasetheCorvetteman on 2008/4/6 1:33:48 Youre using THE WRONG OIL for a start. Why you would think 20w50 should be going in an engine that has a factory spec for 5w30 is something im having alot of trouble understanding. The comment about the warm weather driving is lunacy if you call 70*F warm, im still using 5w30 and i just went through 2 months of 100*F plus. 20w50 is TOO THICK and that is why its not getting to the top. Youre saying youre using LS7 lifters if i remember correctly, and as far as i know, the LS7 specifies 5w30 as well. I know for a fact its not calling for 20w50. The oil reaches the top through the lifters, then up the pushrods, and into the rockers. I think its a pretty big ask to make 20w50 flow through a system that was designed around 5w30. The fact you have such a high oil pressure when the engine starts is indication enough to me that the oil is too thick for the job. The gauge on the dash only goes to 80psi!! |
