i did a compression test, hot engine, PowerFC disconnected and WOT, 7 cranks, and my numbers were 240-245-245-245...so, i do the 240 one over and over, 7 cranks each time, and it is like 240-235

...so, i then take literally ONE THREADS worth of oil, put it on the threads of the comp. tester, screw it in, and its now 245 everytime; without fail, itll hit 245+ each time but before the literally one/2 threads worth of oil on the threaded end of the comp tester, it was 235-240

Harry aka Ndcissive said it is possible there was a slight leak around the threads of that cylinder, however, I did screw it in rather snug... Ever seen this?
