During reinstall of a freshly rebuilt motor we discovered one of bolt flanges (also called dog ears?) on the driver's side heat exchange was cracked at the weld. We decided to proceed with installing knowing that I would need to get it addressed soon. Well ... that flange completely broke off when mounting it.
I have no experience welding nor do I own the welding equipment - my question is can that be welded back on good as new ... or do I have to replace the exchanger? The heat exchanger is in great shape with no signs of rust or leaks anywhere. So it would be great if I can have it welded vs. needing to replace. Thanks in advance. |

My saga continues on this damn HE.
The dog ears line up with the head studs now, but … the dog ears are too high up on the pipe and there’s a small but present gap at the top of the pipe where it should meet the washer and head which is obvi going to be an exhaust leak. I’ve never cursed so loud. I’m done with trying to have these dog ears re-welded. Need to find a nice used or new HE. Should have done that from the start. Would have saved me $200 at the welder, lots of time, energy, and a ton of gas going back and forth to the welder. Anybody have a 2.0 driver’s side HE laying around they can part with? |
