compression test
today i did a compression test on my truck and replaced all the glow plugs with motorcraft plugs, boy do i know what yall were talking about when it has t do with autolite plugs, i caught nine kinds o hell trying to get them out the head. three of them were beru plugs came out wit no problem. 5 were autolites and everyone of them were swole up on the ends. just glad i got all of them out without any breaking. my question i have is what is a normal reading for the compression on a 6.9, and does these sound alright #1-400, #3-400, #5-410, #7-395, #2-400, #4-395, #6-398, #8-400 ?

Those numbers sound good. Just tested mine last week (93 F-350 DWR 7.3 IDI Factory turbo 281000 mi.) i got between 330 and 350 psi in all cylinders. By the way not an easy test with the turbo, it pretymuch has to be removed to test the last 2 on pass side. Got to fix the exhaust leaks so it was worth it.
