531 head?

rogerthechorister · Feb 25th, 2015, 13:48

It looks worryingly as if the 531 head on my B230ET may be beyond effective repair. Someone had helicoiled No1 cylinder and then someone (presumably someone else) has fubarred the helicoil. One engineering firm has run scared of trying to remove the old helicoil and put a bigger one in already...

Anybody got a 531?

Please?

It needs to be the one for the B230ET - not the later one for N/A engines.

No it doesn't you can just swap the exhaust valves over. There's one on ebay.... but it's in Latvia.

I may be wrong but I think the valve seats were stellited in the turbos as well.
