Car Forum / Honda Cars / April 2006D16 << Cylinder head STUCK to block
I removed all head studs, belts and even removed the cam and the head still won't come off. I even went as far as beating it with a plastic mallet - doesn't move a hair. Removed still the entire intake manifold with no progress. Sprayed the hell out of the seam with PB blaster. Not breaking free. Any ideas? > I removed all head studs, belts and even removed the cam and the head > still won't come off. I even went as far as beating it with a plastic > mallet - doesn't move a hair.

Any ideas? ---------------------------------- If the valves are all closed anyway (can't collide with anything), wouldn't SPINNING it over pop that sucker off, or just crack it in half? :-( 'Curly' >> I removed all head studs, belts and even removed the cam and the head >> still won't come off.

I didn't even have to tap it. This one is like fused in place or something. I'm very interested to know possible causes of this. Is it common? I realize the motor is old, but it was taken out of a _running_ car not 6 months ago. I first thought it may be warped but still it seems like there is nothing holding it in place but it's stuck anyways. >> I removed all head studs, belts and even removed the cam and the head >> still won't come off.

I took a fairly thin chisel and picked a spot where I could hammer it (more like wedge it) into a spot where it wouldn't affect the head/block seal, and then once I got it in I pryed it open by hitting the chisel downward. Now I have the same problem with another D16 I'm taking apart. The transmission won't break free from the block. It's really pissing me off. > I removed all head studs, belts and even removed the cam and the head > still won't come off.

Not > breaking free. Any ideas? One common trick is to feed lots of rope down the #1 or #4 cylinder's spark plug hole with the piston part way down, then crank it over by hand. The piston compresses the rope, then (theoretically) levers the head off. If cranking it by hand doesn't work, operate the starter motor. It's possible somebody used sealant at the last gasket change, or corrosion is holding everything together, SignatureTeGGeR® The Unofficial Honda/Acura FAQ www.tegger.com/hondafaq/ >> I removed all head studs, belts and even removed the cam and the head >> still won't come off.

Does one corner have protruding metal tabs where you can safely pry it open with a screwdriver tip? My previous two cars had those for the valve covers but I've never tried taking a head off. > > I removed all head studs, belts and even removed the cam and the head > > still won't come off.
