My timing belt snapped recently. I just replaced it, marked the cams and crank timing, torqued the tensioner, and double checked the valve clearances. I got everything ready for the cylinder compression test, I followed instructions and this is what I got: Cylinder #1 and #2 are at 200, cylinder 3# and #4 are at 190... this is good news? "Dry" test so I'm guessing a "wet" test would reflect compression a bit higher? Thanks for your helpful video btw. 👍
As for “wet” and “dry” testing that’s a good test to see if your psi goes up on any cylinder that is low on compression. Let’s say cylinder 1 was at 100 psi DRY then you put oil in cylinder 1 and it jumps to 140 psi then you would assume that piston rings are bad causing the loss in compression. I say put it all back together and get it running. Check for any issues after doing repairs. I fixed a prelude H22 the belt snapped at 30mph I took on the job replaced timing belt kit and brought it back to life so there’s hope for you my friend! Good luck 💪
@@builtjfilion934 I got a chance to take it out and drive it today and I must say I was very confused and disappointed, the car felt hesitant and lacking power. I'm confused! I cuádruple checked the timing marks over and over, i rotated the crank like a hundred times, yet this is the outcome..? I've never done this type of repair before but after reading through a number of forums and watching instructional videos like yours i developed the confidence to try and fix it myself. I strongly believe I messed up somewhere along the way but I'm completely puzzled as to where exactly, I can't pinpoint what needs to be addressed.. I'm strongly leaning to the timing mark on the crank is off maybe by a tooth due to my inexperience in the angle you're suppose to stand at to confirm the aligning lines.
Really appreciate you making this video, helped out a lot. Straightforward and to the point.
Thank you
Glad I could help thanks for watching 💪

That’s actually great!! That’s healthy compression, are you having any issues with the car starting now?

@@builtjfilion934 Just started it last night, everything sounds great. Thanks
