Noel
When I rebuilt the engine the kit came with new valves. This bent one was from the kit. But the old valves were still within spec. Re-faced the old one and used it. I would not trust myself to straighten it properly.
I was teasing about straightening the valve Eugen. :giggle: But it’s something I would try. That’s just me.

@propane1 Noel, the stem was straight. The hat of the valve was leaning on a side. Watch your mailbox for it. Please send it back straight! :D :cheers:

@Eugen What kind of insert did you use ? What did you do to keep it from moving again ?

Made of steel, comes in a kit for fixing damaged spark plug threads. This time I used jb weld to keep the insert a here it should stay. And for good measure I put some indents on its rim up top with a small chisel.

So you put the insert in to fix spark plug hole in head, and when you put the plug in the insert screwed in farther that you had it. ? Just wondering what happened Eugen.

Exactly like that. The insert fix was done first by previous owner. But I put a new insert at some point. I probably didn't glue it well or something. 🤷‍♂️

I don’t know much about those inserts. But I would of thought the the tread would have been tapered, like a pipe tread, so it could only turn in so far. Never knew you had to glue them.
But like I said, I don’t know much about them. :106:
