AussieLeigh Posted January 8, 2009 Share Posted January 8, 2009 Hi, I have a Chrysler 66. It is getting hard to start and I have to put my hand over the air intake and completly block it off so fuel can be sucked up into the engine.Does this mean my compression is to low? I have a slverdome head and the compression is around 60 psi per cylinder. Or could it be a sparkplug/ timing problem.Leigh Link to comment Share on other sites More sharing options...
AussieLeigh Posted January 9, 2009 Author Share Posted January 9, 2009 Thanks for your help. I did the oil trick and the compression improved by 15 psi each cylinder. Looks like the head is coming off. Fingers crossed I'll get away with a hone and rings only.Leigh Link to comment Share on other sites More sharing options...
Guest FX1975 Posted January 16, 2009 Share Posted January 16, 2009 60 psi is low however low compression could also be attributed to valves not sealing properly lapping these and regapping while the head is off would be worth your while. How many times did you turn the motor over to get this reading? If you are having suction problems at the carby check that all intake manifold bolts are tight and that carby mounting bolts are tight as you will lose suction at the carby if there is bypass through one of these joints if it is loose or gaskets are perished Hope this helps Frank Link to comment Share on other sites More sharing options...
Guest LR1970 Posted February 13, 2009 Share Posted February 13, 2009 Thanks Frank, I checked and tightened everything and now my car starts again. I'm going to leave it alone now! Leigh Link to comment Share on other sites More sharing options...
