What can I do about this and take it off safely?

2000 grit sand paper with 30 weight motor oil.
Do it with the cylinder horizontal so nothing ends up between the piston and cylinder wall.
Wipe it dry with a clean paper towel then apply a thin coat of clean motor oil.
BTW
Did you paint the supercharger sealing surface of the LIM?
If you did I would take that off of there.
Honiing stone or maybe a buff with steel wool/green scrubby. I once took a cam to a machine shop to have it polished and the owner explained that basically they would use a green scrubby and some oil, lightly rub. That's a basic polish to get surface rust off. It worked great for me.

I cleaned off the surface rust and that **** worked great especially with the motor oil thanks guys :)
The work on the head should be OK but if you can see any really jagged metal in that chip I would get a really small grinding bit for the Dremel and smooth it out. It's the exposed casting grain that will cause detonation. Under hard acceleration a little glowing ember will fire that cylinder off early. People polish the combustion chambers for the very same reason. The smoother the less chance of pre-combustion.
i think i got it all down compared to the sharp edges it had and really cleaned them up pretty good especially the block.Quote:

Do you mean in the red circle?Quote:

correct
my heads are cracked in about four out of six cylinders.
Some of them go about 0.250"+ back too.
Go team 3800.
Ok so i finally cleaned up the heads and block i just have to take one bolt out of the head since it is blocked by a manifold bolt and doesnt let me take it out.
But is there a way in wich we shoud torque the bolts? meaning the top bolts first or bottom ones?
There is a torque sequence/pattern. should be in the box with the new head bolts.
Working length wise start at one of the 4 center bolts and work your way to the edge diagonally across center then across.
Then go across centerdiagonally
Then go across
7 1 3 5
8 4 2 6
Thanks the numbering helps lolQuote:

The hex on the end of the exhaust stud holding you up is a 5.5mm. If it's rusty or you strip the hex, put one of the exhaust nuts on it backwards, then put a nut on forwards and using two wrenches, lock them together. That should allow you to take it off.
Thanks never would of thought of that i think that would much easier to do i shall give it a tryQuote:
