Thread: V8 intake plenum removal - front bolt rounded - ideas?

weld something onto the rounded bolt so that pliers can grab onto

Yeah was thinking about welding a socket to it. No access to a welder until Saturday sadly...

How about hammering a slightly smaller socket into the rounded head so it "bites" then undo?


Did this with my stuck locking wheel nuts and it worked!


Cheers, Jerry

A flat ended pin punch around 8mm in diameter and a medium hammer. Hit the punch firmly to mushroom the bolt head and hammer the socket on afterwards. Failing that drill through the head and replace the bolt with a standard hex head jobbie after.

Might give the punch a go, bee utey. Little worried about steel bolt wrecking alloy manifold thread though.


Also thought about removing alternator and front section of plenum/upper manifold for better access. Then cutting a groove in head with hacksaw or thin cutting disk and attempting to turn with screwdriver, or impact driver if space permits.


Reckon I'll end up drilling the damn thing. I'll post up results!


Cheers all.

Try this. The imperial ones are cheaper. Once the nut is rounded I don't think it matters if you use metric or imperil ones of these.


I got mine from Bunnings or Mitre10. Worth $45 for your time and effort.


Once you've used this you will need a new bolt.
