when you tryed C test it wasnt seated properly
yes oil will help make it seal and clean the threads

Check the valve clearances on 4 before you pull the head.

if you can get your hands on a leak down tester, it can supply really useful information for determining where the compression is being lost. do a google search if you aren't familiar with what a leak down tester is/does

i had a leak test. showed at the time 90 percent on nuber one, but the mechanic said to let it idol alot and rev it up, then change the oil and do the same and then take more test
