s] Four cylinder woes, part two!=0A=0AOkay, here's the latest! I finally=
got to pull my head. If you=0Aremember, I had 155 lbs of pressure in cy=

e head off, I was prepared to=0Afind a problem with I flipped it over to=
expose the valves, no such=0Aluck. Other than number two exhaust valve=
being a bit black, no=0Acracks, nothing stuck and it looked fine. So th=
en I went to look into=0Athe cylinders themselves, walls smooth, flat hi=
gh compression pistons=0Asmooth, number three a bit rough on the top, bu=
t other than that and=0Agood. So then I went back to the head, put the s=
park plugs back in and=0Afilled the combustion chambers with paint thinn=
er to see where it=0Awould leak out. Filled each chamber evenly and wait=
ed. Twelve hours=0Alater, and other than evaporation, no leaks! All cham=
bers still even=0Ain their fluid retention. So then I rotated the crank=
to get all the=0Apistons to an almost even position and put paint thinn=
er in the=0Acylinders at the same depth. No quick leak, not one cylinder=
faster=0Athan the others and all the fluid finally drained out smoothly=
and=0Aevenly in each cylinder. I'm a bit stumped. My next step is taki=

Also as a side note, I went over the head with a magnifying glass and=0A=

It didn't drain out and just sat there.
