I upgraded 30 over pistons remanded cylinder head with a cut crawler cam that is supposed to work with all oem parts the engine sounds almost as is it doesn't have compression my friend and I messed with the timming over and over and got nothing as the motor turns over I can here a slight puffing noise I have fuel and spark so I pulled the head to check the valves to see if aany are bent and they look ok but... I did find a peace of packin peanut that I missed during assembly that must have been lodged pretty deep before I put it together there was a lot of fuel in the intake vains when I took the plenum off any ideas I'm seriously stuck.

How much compression does it have? Crank & Cam Timing marks ligned up correctly? With #1 cyl @ TDC, compression stroke, is the dist. rotor pointing toward #1 cyl plug wire? Did you adjust the valves? Little mo info!

Yes all that has been done many times over the engine definately has compression I havnt checked the actual number, I dnt know if its just coincidense but the intake vains were full of fuel but number four plug was the only one that had fuel ON it.

When you do check the compression, post the results with psi #.

Will do is it possible that an oem sized head gasket is to thick?
Replypushrod, October 17, 2013, 19:19Master
NO, if it is the right one for the engine it should be ok! How much valve lash do you have with this new cam? (What did you set the valves at, valve clearance)? And you say only one plug is getting wet.? No backfire when trying to start? Are you doing the work?

Just a thought , going from the other info posted, try drying the cylinders out (plugs out -compressed air for a minute or two each) , get a FRESH set of OEM plugs and put a FEW drops of oil in each cylinder. Unplug injectors and crank over a few times, then plug the injectors back in and make sure all your intake (mass-air) is hooked up correctly--NO LEAKS between air filter housing and throttle body!!!! Then loosen exhaust a little somewhere in front of the converter to let it breath. My theory is you've got plugged exhaust causing the cylinders to flood and wash the rings etc...............mind you ....just a thought , but I've seen it before. Good luck.

Know much about degreeing a cam I was told it was not nessecary but now it seems I should have its the only thing thatakes sense wen I go to adjust the valves the lobes don't align with the valves I'm supposed to adjust
