I'm pretty sure my engine blew a few days ago. I checked the compression to see if it did. I checked it with the car cold and got 90 PSI for the front and 0 for the back. I thought if an apex seal blew I would still have some compression. So I'm wondering if its possible that I blew two seals at once or maybe I have some other out of ordinary issue. I listened to the car crank without the sparkplugs and could hear no air escaping from the rear holes. The car runs, but will not idle and revs real slow. It runs the same whether or not the rear spark plug wires are attached, so I know the rear rotor isn't doing anything. I just want verification, is it blown?

 

yes it's possible. keep in mind when a seal breaks that chunk of metal is still in the engine and can take another pass at the 2nd apex seal and then the second can take a shot at the third, not to mention the scarring to the housings all of this causes.

 

Yeah thats what I was afraid of. Well it might not be such a bad time to learn how to rebuild an engine...
