90 crx wont start.

[jwatson619]

my brother bought a 1990 crx si, that wouldnt start. We diag. it to be a blown headgasket, valve cover gasket due to oil ontop of the spark plugs. So we went and bought a new headgasket, valve cover gasket and new gromits. After taking it apart and cleaning the head best we could, and then putting it all back together. It still wouldnt start. So we took to looking for spark, and found the distributor completly burned up. So we got a new distributor and a just put it on today, and it still wont start. We just got done checking for spark on all the wires, and and went ahead and did another compression test. the left 2 cylinders which originally were the bad ones now read bout 92psi and the right 2 cylinders now read 62psi. If anyone knows why this would be or could help us diag even further it would be much appreciated.

probably needs a valve job or a head resurfacing. the seats are probably leaking a little or the head is warped. valve jobs should always be done when doing a head gasket. it should at least run like crap but maybe the compression is so low in those cylinders that the engine cant compress the air fuel mixture enough. did you check for stretched head bolts? and what kinda torque wrench did you use? and was the wrench calibrated. the calibration does wear away after a torque wrench has been used alot or dropped, or banged around in a toolbox

185 is the compression required but 135 is the minimum compression allowed. and thats at 250 RPM with WOT. youre not even close

would dropping a new motor in it fix the prob?
