Thanks for the ideas!

The common chamber is made up of a top and a bottom section. The top section has 6 bolts that fasten it to the bottom section. The bottom section (intake manifold) has 4 studs/nuts which attach the bottom section to the 2 heads (2 studs/nuts into each head). All the surrounding stuff is gone.

None of the 6 top section bolts have been removed yet. The 4 nuts attaching the bottom section to the heads have been removed. The bottom section (intake manifold) will not separate from the heads. I can clearly see the gasket all the way around but there is no separation happening yet.

I even went so far as to put a chain under the whole common chamber unit and lift up with the engine lift... the entire engine and engine stand lifted up off the ground but the unit did not separate from the heads.

I will try again later.

Thanks again.

Looking at the gaskets, and if you are referring to intake manifolds to head, there are 4 bolts/studs per head.

I'm currently trying to separate the crankcase (upper oil pan) from the block.

All allen head fasteners are off and the two nuts are loose. Front main seal cover is unbolted (I can get the upper part of the cover pryed away from the block a bit but the bottom is stuck fast to the crankcase. The mating surface is tight and I can't even get a thin paint scraper in between. A razor or utility knife might barely start to go in between.

Those side bolts on the lower part of the block don't connect to the crankcase do they? I've pushed down on the lower oil pan portion with all my weight but no separation so far.

Any tips for this?

Thanks!

How many bolts did you remove?

Those look like marks from the casting. Are they flush with the surface or can you feel them?

Do you have access to a welder?

I am at the point of needing to drill the extra holes in the new piston ring lands for the oil consumption problem. I do not want to screw this up.

I have a drill press and am trying to set up a rig to hold the piston (rubber base for the piston to lay on and rubber on top to be clamped down). Because of the piston's shape (cylindrical but not a full cylinder) it may be difficult to hold down. Not sure if it is going to work but if it does, I think it will be a time-consuming process to get the piston into the proper position for each hole (I don't mind spending the time). The slowest speed of the drill press is 540 rpm.

(I do have a variable speed hand-held corded drill which can spin much slower but I'm leery of handheld with the tiny 1/16th size bits and holding the piston is still a problem).

I'm going to use a Dremel with a tiny bit to put a pilot divit in the hole location before drilling.

Any tips for getting this done successfully?

Thanks!

If you have a drill press I would probably build a jig. Some wood, a piece of PVC pipe and a hose clamp. Or just freehand it will the hand drill.
