ect: [Healeys] Four cylinder woes, part two!<br> <br><div><div>Okay, here'=
s the latest! I finally got to pull my head If you remember, I had 155 lbs=
of pressure in cylinders 1, 3, and 4 and only 25 lbs in cylinder number t=
wo. So with the head off, I was prepared to find a problem with I flipped =
it over to expose the valves, no such luck. Other than number two exhaust =
valve being a bit black, no cracks, nothing stuck and it looked fine. So t=
hen I went to look into the cylinders themselves, walls smooth, flat high =
compression pistons smooth, number three a bit rough on the top, but other=
than that and good.</div><div> So then I went back to th=
e head, put the spark plugs back in and filled the combustion chambers wit=
h paint thinner to see where it would leak out. Filled each chamber evenly=
and waited. Twelve hours later, and other than evaporation, no leaks! All=
chambers still even in their fluid retention. </div><div>  =
; So then I rotated the crank to get all the pistons to an almost eve=
n position and put paint thinner in the cylinders at the same depth. No qu=
ick leak, not one cylinder faster than the others and all the fluid finall=
y drained out smoothly and evenly in each cylinder. </div><div> =
I'm a bit stumped. My next step is taking the head to a guy in=
town, an old machinist who builds his own engines and runs his car at Bon=
neville in the 300 mph range. He knows what he's doing and I'm sure he wil=
l give me some sage advice and help. Also as a side note, I went over the =
head with a magnifying glass and can see now cracks, but that doesn't mean=
they are not there I know. I was just thinking with a 100 pound plus diff=
erence, something would be obvious. </div><div> I am=
also going to be taking off the tappet cover on the side, inspect all the=
lifters and see what I can find there. Like I said, I'm a bit perplexed, =
but I'm not done. I will find something wrong! Here are some photos for yo=
u, maybe you can see something I can't.</div><div><br></div><div><img alt=3D=
