#$% 83 240D My cylinder head won't come off!

I just replaced the engine in my 83 240D. Now I am trying to reclaim the old engine but I cant getthe cylinder head off!! Maybe the problem is I used Hylomar to seal the Head Gasket. No matter how I hammer, kick or throw the engine around I cant get the head off!!(Facetious)
Any ideas? I tried a ten pound sledge and wood block, no use!!

What is Hylomar? Can I use it to re-attach the wood on the dash?

The combination of sealer and ONE bolt still in place is enough to give you a H.... So are you sure you have all the bolts out.... Can you guess how I know to ask about this ?

When I pulled the head, or I should say tried, on my daughter's 240d we jacked up the front of the car, placed a 2x4 up from the floor up to the exhaust manifold then slowly lowered the jack. This is how we broke the head loose. I know the engine is out of the car in your case but I'm sure you'll come up with something short of plastic explosives.

You might consider something harder than the wood block ... I have sometimes been surprised at how much impact a wood block can absorb. Try large chuck of plastic ... big handle on a screw driver using the sledge?

Is your wood block pine or something harder? Sounds silly, but an oak piece has worked in some cases for me when pine did not ... I have also had to go steel on steel before, but would certainly NOT do this with a head, aluminum or iron.

My first thought was the same as leathermang. Don't forget the small bolts in the timing chain well off to the drivers side as well as the one or two that are around the outside of that part of the head.

Good luck,

Like the above post.. I think there is a bolt or two down in the front part of the head down by the timing gear.. Got to get those too.

The chunk of 2x4 I used was doug fir and I put a corner of it inside a port of the exhaust manifold then slacked off the floor jack SLOWLY and the head gently was lifted off. BTW I was a little nervous about the possibility of loosing those cap screws that are down inside where the timing chain is, especially when I was putting things back together. what a drag that would be. grooon

I can remember a similar problem with the 220D. Seems a socket head capscrew in a counterbored hole was covered with black oil...Like Leathermang and Larry said, make sure you have all the bolts out. Once I got the bolts out, a few medium raps got it loose. But you have to get those bolts out...
Good luck, Jim
