I'm pretty much like you Jim in that respect, I know more about fabricating cars than building engines. What is funny about that is friends and coworkers automatically assume that because we know how to build a car from the ground up that we are really good mechanics. I get people all the time at work and all who come up to me and say "Hey, you know a lot about cars, I have this 2001 Toyota and it's making such and such a noise." I have to tell them I have no idea what it could be, and that I usually take my daily to the garage if it develops a problem. I know they think I am just blowing them off, but it's the truth.

I see these guys on here who really know their engines and know one end of a degree wheel from another, and I envy them.

BTW, glad the oil pump seems to have solved your problem.
