I have a 92 metro..compression for a new motor is 205psi per cylinder..anything under 160 is rebuild time..new exhaust valves,stainless steel is best, compression is tested on a hot motor, throttle wide open and all plugs out..the new head gasket will have the ouil return holes way too small..you can see this when you place the gasket on the block..upper right and left corners..enlarge them other wise oil doesn't draon back fast enough and you will have a smokescreen behind you..it;s a known problem..but noone has corrected the gasket at any of the manufactirers |
