Can hydraulic lifters cause a no compression situation, and if so, can they be bled by hand? ---

Do you mean no cylinder compression, or no compression of the hyd. lifter? ---

I’m not getting any cylinder compresison, and I believe that when the camshaft’s cam out of the car, extra oil go into the lifters, causing the valves not to close properly. ---

I did alittle more investigative work. I’m not sure if this is a problem or not, but the inntake camshaft lobes are not even hitting the lifters. There is about 1/4 inch a clearance between the two. I checked on the exhaust camshaft side, and every lobe is touching the lifters. Could this be why I am not getting any compression? Assuming this is the way it should be setup, the valves should in theory be closed, allowing for compression. I guess if I dont get a definitive answer, I will need to rip the head off the car and diagnos the issue from there. Here are some picture’s. ![http://66.93.172.84/sean/Camshaft/Picture001.jpg](http://66.93.172.84/sean/Camshaft/Picture001.jpg) ![http://66.93.172.84/sean/Camshaft/Picture002.jpg](http://66.93.172.84/sean/Camshaft/Picture002.jpg) ![http://66.93.172.84/sean/Camshaft/Picture003.jpg](http://66.93.172.84/sean/Camshaft/Picture003.jpg) ![http://66.93.172.84/sean/Camshaft/Picture005.jpg](http://66.93.172.84/sean/Camshaft/Picture005.jpg) ![http://66.93.172.84/sean/Camshaft/Picture006.jpg](http://66.93.172.84/sean/Camshaft/Picture006.jpg) ![http://66.93.172.84/sean/Camshaft/Picture007.jpg](http://66.93.172.84/sean/Camshaft/Picture007.jpg) ---

I have more time working on pushrod engines, but I would think that the valves would need to be completely open for you to have zero compression in all cylinders. Since you are thinking this is an intake vavle problem, I would also think that you would be able to hear pressure escaping through the throttle body, while your doing the compression test. I also wonder why none of the lobes are touching on the intake side??? ---

Well, after talking to someone more knowledgeable on the heads, it seems I have bent the intake valves. I’m assuming the crank went 180 degrees out, causing the issues. I can get a head for around 100 dollars shipped. I guess it’s time to start on engine work! ---

how the hell did that happen? i see what looks to be chain sprockets not a belt. did you rule out the possibility of floating the valves?
