h22a, 100% stock internals.

i pulled in one day after driving and my firewall was covered in oil and there was light blue smoke coming out of the valve cover breather, oil cap and the dipstock. it sounded like it was missing. started looking it over, started it and it smoked on start up all day long through the valve cover etc and a decent amount through the exhaust, it smelled a lot like gas.

did multipul compression tests; cylinder 1, 65 2, 180 3, 180 and 4 155 psi. i was thinking rings or piston and i also had no oil in the water or vise versa. h22a should be 220 in all 4. cylinder 2 3 4 all lost about 20% compression (4 was 210 when i first bought the car, the others were 220 225 etc.

after i pulled the motor, i bought a leak down tester, my intake valves seemed to be leaking on cylinder 1 and slightly on cylinder 4, so i thought either valve, or the cam slipped or something.

i noticed i had no blow by to the crank case while doing the leak down test, so that ruled out pistons and rings for me.

i took the head off yesterday, flipped it upside down poured gas into the combustion chamber, no gas leaked through the valve seats, the cylinderwalls were flawless, couldnt even get my fingernail to catch the carbon line on the cylinder walls and the pistons still had visible factory coating, barely any carbon build up. head gasket looked almost new.

what else would it be? i had my dad check it out, hes an old school motor head. i talked to one of his diesel mechnics that works with him and a few of my friends, we are all stumped.

I know a good number of you on here have your own shops, and have been building honda motors for 20 years now, im praying that someone can help me out here, see something that im not seeing.

 

bump.
