Default Socket size to hand crank 3800 series 1

Hello. I'm seized up and need to crank it by hand to purge coolant. Anybody know the size of the socket I will need?

If my memory serves me correctly it is a 1 1/8" socket. I know it isn't metric. You could also remove the dust shield and use a flat screwdriver on the flywheel teeth to turn the engine.

1 1/8 too big. 24mm worked. good amount of coolant came out of one plug opening (between a cup and a quart). Maybe
a teaspoon out of its neighbor.

So how do I know if its head gasket on LIM?

Car has never overheated.

Cranked it clockwise BTW...assume that'* correct.

Which cylinder was it? If it was the one closest to the throttlebody, I would suspect something in the intake tract.

I would do a compression test. If it is the headgasket, it will leak compression in to the cooling system. If compression checks out, I would tear it down to the LIM gaskets. You should see evidence of leakage once you get in there. I suspect however you will see it as soon as you get the throttle body off.

For some reason I keep thinking the rear drivers side is the first, but I could be wrong. It is the correct side of the engine at least if it is ingesting through the intake. I keep coming back to the throttle body gasket to be honest.

If you are looking for an easy check, You may be able to look down the throttlebody with a flash light to see if you can see a leak. The MAF screen will probably be in your way, and a coolant pressure tester will likely help you out.

On a plus note, if you were looking for an excuse to do a LIM gasket job, you may have it, assuming a compression test doesn't prove it to be a waste of time.

@93PA

I was wondering if you ever figured out what caused it. My Regal GS is having the same symptoms.

What year is your Regal, and does it have a plastic or aluminum upper intake manifold?
