    I just took the shrader valve off my cheap autozone compression tester so it would allow air to enter the piston then hooked it up to the compressor. Easy way to tell if you have bent valves.

    Qustion tho i set the piston at tdc for each and then rocked the crank back and forth till i head more air comming out the intake then axhuast to find the excasct center. At this exact center there was leakage for both the intake and exhust so i guess that means i have hent all my valves. Should there be commpression at some point when they are all closed?

    not sure what ur runing but some cams have an overlap were the exaust and intake are open at the same time.
    dosent mean you bent all of your valves

    Its an h22a autotenshioner went bad. Also did the test at the point in the stroke where none of the valves should be open(both lobes of cam pointing up) and air poured out of the exhuast valves. Started the compressor at like 20 psi and turned it on to see if i could get any compression and got none :(

    If you have no compression, your valves are broked. yes.
    That sounds consistant with the timing belt slipping also.
    Fun times ahead.
