1988 bentley eight right hand manifold removal help

Ok so I have a blow from the right hand manifold. It sounds like a tractor under acceleration. It's a 1988 bentley eight. It has lock tabs and bolts holding the manifold to the head with spacers. I managed to get one of the eight bolts undone and thought I'm in luck. Second one the bolt head rounded off with a 6 sided correct size socket. Now access is awful. So I cut the spacer or as much as I could away to try and relieve the pressure and still it wont move. I cant get a smaller socket and hit it on because of access so does anyone have an idea or has anyone ever had this problem and what did you do. As I dont want it to snap on me but very stuck !!!

If you have access to an air chisel, you can nudge the edge of the bolt head. When renewing the bolts, use a smear of anti-seize and torque correctly. They are low torque, hence the lock tabs since they are known to loosen over time.

Hi Chris, Same response I have put up on the other message


Obviously as stated as much penetration solution as possible. I had to change my manifold gaskets a few months back on my SS1 so I don't suppose it is much different. Had excatly the same problem with one that was a rounded head.


Amongst all my array of tools I thankfully had bought a 'superwrench' set from USA many years back and it ended up the only tool that I could get in the space and fit over the spacer and bolt head and managed to turn and remove the bolt.


Standard 'stilson' type wrenches were just too big at the end. I wonder what similar tools anyone else has because I have never seen these type of wrenches for sale in UK.


Wish you best of luck... I agree the prospect of it shearing was worrying as no way to access to drill out
