A few weeks back I asked the group for advice on cleaning out the water passages in my block before I installed my new radiator.
The group consensus was that I should pull the head and thoroughly clean out the water passages. Yesterday I pulled the head, and I am glad I did. Besides lots of scale, some critter had stashed nuts in the engine block. Here is a photo of some of the "stuff" I found inside my block:
Thank you for the good advice.
Thanks for posting the results! Often there are discussions here but we never learn how things turn out. Very glad things worked out for you.
Time and effort well spent. Your engine and radiator will thank you; the engine will run cooler and the radiator won't get plugged with that junk. Bravo.
RATS (pun intended) Guess I'll have to pull my head--didn't want to disturb the engine that much, but guess I'd better, don't want to mess up my rebuilt radiator. Oh well, can check for two-piece valves while I'm in there. I have plenty of head gaskets--that wasn't my worry, I just hope the head bolts come out without problems. . .
If you have access to an impact wrench, they will often remove head bolts that would be ruined or torqued off using a socket and breaker bar. Use a low setting and gradually increase the torque.
Good idea--now to figure out what box it's stored in!
Don't forget to check/clean the 3 steam holes in the block and in the head while you have the head off.
