Re: This is what is left of the "free" TR3 engine.
Hey Jim,
Yes, the threaded hole for the drain goes on into the area of the #4 sleeve. The inside part of the hole is a cast hole, not thread thru-and-thru. The only other passageway for the water is the rectangular cast hole in the front of the block at the water pump. There are no other holes, save the large rectangular hole between #2 and #3 sleeves. Looks like the figure-of-8 gaskets are the only thing that keep the water out of the oil sump. You are right if you are assuming that this seems to be a poor flow of water to cool the sleeves, unless the head finishes the job. I would assume the head (mine is now someone's boat anchor) has water passages that would allow for flow through the block. Sorry I can't confirm that for you.
Want a block? Anyone? You make the crate, you pay the freight and it is yours, free! Or come over here to South Loosiana and pick it up, literally. The darn thing almost took my back out getting out of the back of my pickup. Should have let my wife do it, she's tougher than me...
Actually, I'd take a hundred bucks for it but freight and building a crate is not something I want to do. Any takers?
Basil, if I keep trying to hawk my engine parts on the forum, you will probably make me go over to the classifieds section. I'll quit.
