Bad Diesel Head Bolt 700

Those bolts can be a PAIN to say the least. I had one where water managed to get up inside the thing and fill it almost to the bottom of the washer and over time turned the alum into corrosion guck that no amount of torque would bust loose. Snapped off the bolt head as the final result and was left with the shank down inside with that guck holding everything together. I ended up pulling the engine out of the car and on a stand turning the head to unscrew the bolt from the block...

As for your issue and not knowing what bolt is giving you the trouble my favorite is to pound in a T-55 TORX bit using a 8-10 pound hammer running it all the way down making new splines going in. Go get the better branded bits on 1/2 drive and use a cheap and I mean cheap-ass 2" extension as your anvil to drive it home. If you're lucky the shocking from the hammer blows will break everything loose and you can get the bolt out, if not and the engine is on the ground your best bet might be to "unscrew" the head from the block.


Good luck and let us know K?
