Whats up, I am currently working on a 93 escort with a 1.9. The engine was overheated because the lower radiator hose slipped off the engine & was not noticed by the driver. It then lost power and came to a stop. Now it will not start (turns over fast) had one burnt spark plug & here is the compression I got from it : #1=20 lbs, #2=10, #3=5, #4=10 then I put some oil in the cylinders and got #1=40, #2=15,#3=10,#4=25 What do you guys think the problem is ? Head gasket & head bad ? Thanks
