Bent Push Rob Saga

@GTX JOHN I did a compression test and here is what I found:
The real kicker here is that I checked Cylinder 2 and 4's compression about 2 weeks ago and both were around 80 PSI. So something is wonky.

@PRH I checked under both valve covers and things look fine. No obvious bent pushrods or anything looking out of place.

@tonysrt the timing chain was replaced during the rebuild.

@mygasser can you describe the test to check for stretch in the timing chain more? What is the rotor arm you are referring to? The distributor's rotor?

@cookietruck
no I haven't pulled the distributor.


*big sigh* it is seeming more and more likely I am going to have to tear the engine apart to figure out what is going on. With Cylinder 4's compression way down, the popping and air coming out the carb, it seems like the timing chain may have skipped? Any advice on the best way to check for this before pulling the front of the engine apart?
