I went on a trip up the peninsula, about five hours of driving. Next morning at the motel while checking things I found the
oil almost gone and replaced with grey gunk. bought 10 qt of mobil 1. The engine had been running warm up the coastwher its cool enough a sweatshirt were needed, and on the way back inland way the weather was warmer but engine wasrunning cooler. Once I returned to home I tested and blamed the Print-O-seal intake gaskets.
The front ends of the intake manifold gaskets where the coolant crossover ports are, was absolutly shreded around the coolant ports. I changed to the Victor-Renze gaskets and haven't had that problem again. The Victor Gaskets FE intake manifold gaskets are availble only through certain retail distributors, not on shelfs, consdered hiperformance = special order =no discount+ shipping and sales tax paid upfront. Sorry I'd like to pay less than suggested list. My standard is it's either sales tax or shipping costs, not both.
