Hi, I tried the search option first but I'm not sure how to describe or what term I should use so Il give it a try here, as you can see in my pictures there is coolant in a place where it is not suppose to... I changed my heads (camel humps) about 2 years ago cause they were cracked. I bought a new set of head machined and tested and I re-installed everything. I noticed after a couple of run a thin "line" of coolant at the bottom of driver side cylinder head after I removed the valve cover, I left it that way since winter was coming and it was put down to rest for about a year. Now that I opened the valve cover yesterday I found a good amount of coolant in the head as you can see, also the coolant from radiator "top reservoir" empty which I found in the oil pan after dropping the oil (very green and transparent and seperated from oil), my guess is it slowly leaked from the top to the pan by gravity by passing through the head and followed the path to the oil pan by the hole completely at the end of the head just to the right of the last rocker near the firewall where you see the coolant to the right just flush with the "dripping hole" or "oil passage". Could this be a distorted intake manifold or faulty gasket and/or rtv void?? Im very sorry if my terms are not accurate. I do my best! Thanks for your help.
You could top off the coolant, leave the valve cover off, and pressurize the coolant system to 20 psi and watch for the leak. For coolant to be where it is, either the head has a crack, or the head bolt is leaking.
@clockwork31 I have seen before crack @ Rocker stud , Do what @Bangingoldtin said, To Verify, I had a 250 -6 one time leaking @ main . saddle. I Drilled ,tap , plug. Also There is Snake Oils that can seal Cracks , Blue Devil in one , & others on More commercial use
