Mike in Pa Posted September 23, 2019 Share Posted September 23, 2019 Finally got the engine out and apart today. Had coolant in the oil. Frost plugs pushed out of both heads and water damage in one cylinder. Quote Link to comment Share on other sites More sharing options...
el_freddo Posted September 24, 2019 Share Posted September 24, 2019 How well did it run before the Welch plugs let go? And how long did the engine sit full of water? I reckon that water damage looks like normal wear. The engine may be high miles but if it worked fine before it stopped, I reckon it’ll go just fine with new HGs etc When I got mine it had sat for 6 months full of water. PO said “it just stopped suddenly one day” and they walked away from it. Then they finally sold it to me. Top of one cylinder had a couple of rust pits but other than that we’ve continued to run this engine. Now I have a detonation issue that has me wondering about the compression on that cylinder. I’ve been too lazy/busy to check so far. We also had the Welch plug holes tapped and a big flat hex headed plug put in. No leaks, and something would have to be seriously wrong for one of them to let go! Cheers Bennie Quote Link to comment Share on other sites More sharing options...
GeneralDisorder Posted September 24, 2019 Share Posted September 24, 2019 It would run. But that's pretty bad. Either bore it oversize (unlikely) or EJ swap it. That's scrap metal from my perspective. GD Quote Link to comment Share on other sites More sharing options...
