So here is the situation:
TR3, mileage unknown
When I started to work on it, bad overheating, replaced radiator, much better but still a little overheating
A few hacks present under the hood when I got it has led me to believe less than skilled hands have been touching it in the past
But over after carb overhaul, distro work, etc engine has been running good, 115 lbs plus on compression
Carbs removed again and manifold removed to ease exhaust system work which is now mostly complete
Today before replacing manifold decided to unstick block drain while still readily accessible (the dreaded "while I'm in there...")
Result is valve was clear, block is not - fully plugged with hard crud, even after clearing with drift and drill only get coolant seepage
My instinct is to pull the head and try to ream out the coolant passages in the block
Questions:
1. We are far enough down that only a few steps remain to pull the head. Any tips, like what to do if it's stuck? Do the head studs have to be pulled as well? What about the trick of turning over the engine with the plugs in or will that do damage?
2. With the head off can I get to the passages enough to try to remove the garm?
3. If I pull the head I suppose I should take it to my machinist. Any things he should do or not do? Should I replace the springs?
Thanks, Dave
