I read around and had mixed results. Is the wx engine an interference
engine? The other day i moved my car (intense cold the night before) it
fired right up and i turned off the ignition. A few days later i come back
and try to crank it nothing, no fuel pump, etc. So i start to wonder look at
the wiring since i put a mac10 in there. Nothings wrong go to the hall, not
at tdc! Look at the cam not there either. Now i got kinda scared. The belt
was loose and there was some scrunched up squirrel nuts no joke! , i knew it
was loose tho and was planning on changing it to the newer longer style and
adding a belt tension pulley. Same reason i dint put to cover back on and
nuts managed to find their way in the bottom cover. Anyways it turned like
1/3 or is it 4/3? a crank turn from the cams tdc. 

Now i put the cam at tdc and was able to do a whole crank turn by rolling
the crank by hand with no belt on. Note it was really cold so less
compression and i did it slowly. Anyways that told me that there's no broken
valves but none were interfering either at that point. So put back the belt
on and tightened it. Did a few engine turns with a 19mm to make sure i dint
miss any sheared belt teeth then started it up till warm. Then did a
compressions check. Not very high... ~120  cyl #2 is at 110psi Are these
numbers normal for a high mileage engine? I never checked this engine
before. I think new its supposed to be at 130psi ?  My cgt's ng is at ~5psi
less than factory new and at 200k. So i am a lil worried atm that i have
slightly bent valves. If they are interference how  much oil in cyl do i
need to put to test the valves? Anybody have some results of a high milage i
can compare to ?

Thanx
