Hi
This is my first post after lurking around a bit. I have a 1981 750F which has been sat around for some time by the the look of it.
I have stripped it down to bare frame and thought I'd tackle the engine first. Wont take too long I thought!
The spark plugs were all very tight but I managed the gently get each started, worked them back and forward and eventually got 3 out. The fourth
snapped off instantly. Easiouts would not touch it and I decided the whip the head off and send it to the local engineers to remove the plug.
Anyway as per usual the head is stuck solid on the studs due to corrosion I guess as the studs are exposed to the elements.
I removed the 2 studs at each end if the head as these are protected from the outside. The 8 that are left will not budge.
Ive soaked with penetrating oil over and over, beat the head with a wooden block and hammer, tapped all the studs to try and shock the corrosion loose,
gently tried prising the head up, sworn a lot, beat my head against the wall, and even prayed, but still the b*****d won't move.
Ive even considered drilling or die grinding through the studs further down in the hope that the head will come off leaving the the top half of the studs in the head. At least then i would have access to the studs on both sides of the head to try and remove.
Ive had search and it seems that most people manage to remove most of the studs which allows a bit of head movement and that allows the studs to release. But with 8 studs thats not going to happen. Been on it for days now.....arggghhhhh
Any bright ideas.....anyone.......please.....before I phone the Samaritans.
