Last fall bought 2003 ej253 that came from Copart car..The donor car was hit in front.. Engine damage is broken drivers side timing belt cover.Timing belt is still on with all timing marks in correct position. Just did a leak down test on engine.Getting 80 percent leak down on all four cylinders at exhaust ports. No piston ring leaks and all four spark plugs have an even ware pattern with no oil fouling. I want to get correct diagnosis. without pulling the heads, because I'm selling the engine.
Doing complete rotation of engine from crank bolt, I'm getting 80 percent leakage thru exhaust ports on all cylinders.So I will do valve lash adjustment on all intakes and exhaust and redo test..
