big Al said:grumpy , I've been dealing with what I originally thought was a defective lifter,and a valve adjustment issue, but after having several more issues, with how the engine was running and low oil pressure,
I pulled the cam and found several lifters and lobes and the cam gear well worn.
I then pulled the engine too find the bearings were also contaminated with trash!
I think the main cause was the oil pump pick-up was partly clogged with old gasket material, so how should I proceed?
reading these threads and sub-links should help, you didn,t state what engine your dealing with and a few pictures would be very useful
