The AUSubaru.com.au Forums

New brumby had a stripped exhaust flange bolt where it inserts into the head.
Brainstormed at work about fixit ideas and had all sorts of recommendations regarding helicoils and chemical putty from rev head co workers. Went to Ausubaru forum and got some good ideas.

However I went to local muffler shop in Toowoomba and they were real good. Cut the flange and turned it around to access the other two bolt holes in the head. Also made and fitted new engine pipe from there around to the other flange while they were into it. Whilst on the hoist, catalyctic converter was found to be on the way out so they inserted new one for me...I thought it was good service and a good result for what would always have been a suspect flange bolt. Cost...about $350 bucks... $$$:???:$$$

sometimes there is nothing like sharing a problem with a pro

this is stolen from anderw T from a different thread

EA81 heads r like EA82 ones in the sense they have two alternate threads for exhaust bolts at opposite sides to where they are now?
If so all you need to do is cut off the end of the header pipe fairly close to the head and rotate it 180degrees and we-weld.
Otherwise maybe re-tap for a larger thread size.


tristan info from andrew

my 92 brumby has riser plates for the egr system that mount off the other two threads

Stolen?????

well i copyed it out of a post he made in a different thread so im just sayin that its not mine

No sweat mate..I'm just saying that I thought it was a better result than inserting a helicoil...peace of mind.... you Know;

Trev

and aren't those riser plates absolute bastards to remove with studs/thread intact ready for another day ??

dont know motors comming out next week make way for ej22 so the riser plates can stay on it
