Heads on 2000 D2

[ezjuarez]

Getting heads done on 2000 D2 with 94K miles. Decided to take engine completely out to change front/rear engine seals, oil pan gasket, and all seals/gaskets associated with head job. Anything else I should do while I have the engine out of the bay?

Thx for your tips

You could put it in my MGB! woo hoo!

Only if it looked like this:

Somehow doesn't that engine look more powerful in an MGB?! lol

 

[Ed Cheung]

It LOOKS powerful indeed, haha.

Cool Buick emblem on the air cleaner.

You could fit a new timing chain and oil pump rotor while you have it all torn down, and if the water pump is original then that could be retired and the thermostat with it.

Use the composite head gaskets rather than the tin ones on a rebuild, and make sure that the faces are scrupulously clean before reassembly.

When you assemble the heads back to the block, get the inlet manifold in place but with just four bolts holding it to the heads, with the original gasket in place. Nip the bolts up to half tight then go through the head pulling down sequence. The inlet can be removed now and new gasket fitted. It aligns the inlet and heads nicely to each other and saves stresses being set up.

The heads have a lot of leeway to move, even though they are dowelled to the block.

Good info. Why the composite over the steel? I've heard the steel last longer.

the heads cannot move around with the dowels. There is no need to do the trick with the intake manifold.

Check the rod bearings while the pan is off. I bet you'll see a lot of copper.

 

[ezjuarez]

Good call on the rod bearings.

since you have it out I would go ahead and attach a chain to it and use it as a boat anchor.
