kev34 Posted February 9, 2023 Share Posted February 9, 2023 I've a few very slack threads for the exhaust studs and was wondering if anyone has rebored and tapped some of the threads in the head to accept 9mm bolts, as there seams to be enough meat left to do that. I can get m9 x m8 stepped studs, which could be screwed into the head and use the M8 for the exhaust flanges. Just a thought. Quote Link to comment
Fazz711 Posted February 10, 2023 Share Posted February 10, 2023 Never seen m9 used for anything. Proper oddball size Quote Link to comment

DAZ Posted February 10, 2023 Share Posted February 10, 2023 (edited) Well I don't see why not as when you helicoil them you drill it out tap it and wind the helicoil in .... Just don't drill all the way though into the cam chest, found it done after chasing an oil leak on a 600... Edited February 10, 2023 by DAZ Addition 1 Quote Link to comment
