installing the oil pan.

[ClaudeC]

I about ready to install my oil pan....I know the pan gasket comes in two halves, I know there is a rope gasket at the front of the pan. Are there any other pieces of gasket that I must be aware? I purchased an entire engine gasket set.

[DaWizard]

Yes, the cork strip that goes on the rear main bearing cap.

And there are as many ways to install that as there are subscribers to this site.

You are welcome Claude, I have been doing this for awhile.

The Leakless Pan also resides in this engine topics technical forum thread

Encountered problem with pan installation. The holes on oil pan rail are all threaded except for one hole which is slightly larger near where the starter is located. Not sure what to do with this. Looks like this larger hole never was threaded.

[DaWizard]

Claude, those pan holes are suppose to be clearance holes. I think pictures of the pan rail are in order, also pictures of the rest of the pan as well. To my knowledge, none of the A pan designs called for threaded pan rail.

[ClaudeC]

Right. The holes in the pan are just holes. Bolts with lock washers tighten into the threaded holes on the engine block pan rail. except the ONE side of the bellhousing for the large flywheel gear has a slightly larger hole not threaded. I will get a photo

[ClaudeC]

The top side of this hole is structured for a bolt head

[Mitch]

This may not help you but have you seen these break downs on this site?

I will check that out. Funny the oil pan under this hole is the only one with thread, Perhaps for some reason this screw is put in from the bottom up. The only problem I see is that it needs a longer screw than the other oil pan bolts? When I got the engine the pan was already off so I could not see how it went together. All the dealers that sell the oil pan screw set, sell 16 screws which is the right number but they are all the same length, that is a problem.

[ClaudeC]

That threaded hole in the oil pan does not come anywhere close to the hole in the block.
So there is not upsidedown bot that goes here. And as far as the shown hole, there is no way a bolt head could fit under the flat portion of the pan " this is in the area of the starter.
The only problem that bothers me is that without this hole, I only require 15 oil pan bolts when all the literature says I need 16 bolts.

[DaWizard]

Claude, I really don't remembering a hole there for pan mounting. That could be a starter bolt hole.

What are the markings on that block?

Also, is there another pan mounting hole nearer the rear main cap on both sides? My memory is not as clear as I would like on this motor, but I am thinking there should be a bolt closer to the main cap on the pan rail.

[ClaudeC]

That is the oil pan gasket with the numbers on it.
It think you are right, about that hole being for the starter.
But I still only have 15 pan holes for bolts and all the oil pan bolt sets sell 16 bolts.
That last hole is actually outside the oil pan and on the flywheel bell. Strange that they would sell 16 bolts when only 15 are used.

[DaWizard]

Oh, not strange at all. See, they make that bolt set to fit ALL the flathead V8s, which some use 15, some 16, whats one bolt to them either way!

[ClaudeC]

Great point...Do some of the later ones use 16 bolts?

[DaWizard]

Yes

[ClaudeC]

here is the pan

[ClaudeC]

Just dry fit my pan to engine, and that rear hole lines up exactly with the threaded hole in the pan. Without the pan gasket the pan screw is just about fits, but with the gasket on I think the screw should be 1/4 or so longer to be able to reach the threaded pan. But that rear hole is an odd one because with the starter connected in the same area there would have been no room to put a bolt from the bottom.

[ClaudeC]

I contacted the place where I bought the oil pan bolts and they told me that the rear bolt should be 1/8 inch longer! But they only sent 16 short ones!
