I'm hoping somebody could help figure out what went wrong with the engine in my 91 Toyota pickup. All 4 cylinders have no compression. I swapped the engine in last year and also replaced the timing chain about 1000 miles ago. It has been running great ever since until one day after school it wouldn't start. The engine didn't quit running while I was driving, instead the problem happened when I tried to start it up.
The engine sounds like it turns over way to easy and doesn't even attempt to fire. It is getting fuel and has spark. I did a compression test and all 4 cylinders have 0 psi. I pulled the valve cover off to look at the timing chain and its still on there.
Today I checked the valve lash and they were all way off. I noticed the compression felt and sounded weak as I was setting it to TDC. After adjusting the valves I'm not sure if its just me but it feels like there is more compression and it also makes a woosh. I tried again with the compression tester but it still showed a flat 0 psi.
I bought a new compression tester to rule this out but the results were the same. It sure does feel like its making compression now but why wont it show any psi?
