I never did read what caused the second leak Brian. Can you explain what you found???
About the factory thermostats. the BEGIN to open at 192 and are fully open at 212.. Thats a working stat.
I believe the use of RTV, and a improperly cleaned cover, or just too much pressure for the RTV to hold.
in post 116, I have a pic of what looks like a lifted gasket.
from the water to the timing gear cover.
this has to be the issue.
ive pressure tested the block with the cover off and block off plates installed and it held up to 20 psi without leakage.
even with rotating the crank, and let it sit, to rule out cavitation.
im really crossing my fingers on this one.
this job sucks and ive depleted my gasket supply.
