Throwing elbows is a mosh pit reference, ha ha.
Man, I know I been around here long enough to know all about heater hose elbows but I have to replace them every few months now and I don't understand.
Mainly I don't understand how the design was expected to work in the first place. They move. It can't.
So, before I set about re-engineering something... talk to me. I could rattle off all that I have tried, and I think I have read it all but I have some questions.
Anybody tap the engine side for NPT threads?
Anybody block the holes with a freeze plug?
Anybody add a second O ring?
Anybody try something else I haven't thought of?
I am tempted to pack a rope seal of some kind in behind the O-rings.
I would like to try hose clamping the elbows to a bracket attached to the nearest available bolts. Just to avoid movement during thermal cycling. But the design leaves me wondering if the elbows are intended to move a little to avoid something else.
This is just a way way way too often repair. Two oil changes means elbow change. Is there hope or is this just my life now?
Thanks for any fresh input.
