The 360 build that has more turns than Willow Springs
Sometimes the head gaskets tell a story as to what happened. I think these two do.
Now, I’m not a professional mechanic but I’ve worked on cars as a hobby since the 80s. I’ve seen head gaskets blow between cylinders, I’ve seen them blow to the outside of the lock and into water jackets. What the heck is this ??
The ring around a few of the cylinders looks egg shaped.
Incorrect torque during installation ?
That was either 1357 or 2468, I don’t remember but look at the back side, this is the cylinder on the end.
The oil isn’t the issue, that just dropped onto the gasket after removal. Look at the weird bulge outward.
I know the guy that built this. He is not a bad guy but it seems everything this guy builds has to come back apart sooner than you’d want. Here you can see where it went to water. The “fire ring” is rusty near the water jacket hole.
The other side isn’t much better:
A small part of me wants to blame the gaskets at least a little but what the heck? I’ve never had this happen to anything that I have built. I’ve thrown a rod, wiped out a few cams but never had a blown head gasket like these.
