Changing oil pan gasket

[themechanic]

Put rtv in the cracks where the timing cover meets the block and in the back where the rear main seal holder meets the block. A dab will do. Just enough to fill the gap.

Are you saying you didn't drain it?
That is step 1.

No no i did, I was just wondering how high the oil level goes to on the pan.

 

[Gygeneral]

Not sure if I'll have time tomorrow but next time I'll try going throught the gasket, if that don't work, put the bolts back in with some RTV and leave it as is,LOL. Just wipe the oil once in a while. I'm going to call the engine builder and ask what the heck he used on those gaskets.

Now is a good time to check for oil pan to sump clearance. You never know unless you built it.

If it is black, it could be The Right Stuff. If so, that is a bugger to get off.

Yes it is black, great!

Some use weather strip adhesive. It comes in black and yellow.

I tried with a wedge and that didn't even do anything except the pan was starting to flex from prying, a knife didn't do anything either, its as if the cork is impregnated with what ever he used. I could see a new oil pan here

I would think if is weatherstrip adhesive, the pan would separate fairly easily? Probably with just sticking a putty knife in the joint.

Almost exactly 1.5 inches below the block.
Was curious so I put the dipstick in and measured.
Also people fill the dimples on the pan becouse instructions for those windage gasket say that.

Not on the 402 Oil Pan they don’t - I really liked the design but it did not work with my pan
Others have said it worked with the factory pans
I used two of these , ZERO SILICONE , ZERO DRIPS - Bone dry for years now since my build
I love them

Two of what, these?

I'm going to pull mine and add more/bigger drainback slots, as my car is apart again, like this:

Me likey. I'm thinking using studs would be beneficial?

Yes on the Superformance 2585

Geez, i would have guessed that the 6 qrts of oil does not fit in my pan, If I ever get this pan off I'm going to fill it and see. I heard also about the filling of the dimples with JBweld, but I'm afraid someday that filler will come loose and get to the oil pan.

Mine looks different, it's from Summitt, where did you get yours

 

[themechanic]

You'll have to straighten the pan flange once you get it off. It will seal without filling the reinforcement dimples.

Have you tried using a heat gun to get it started coming loose?

I’m gonna take a step back and ask are you positively sure it was the oil pan gasket that was leaking to begin with? As well as it seems to be sealed it makes me wonder. Valve covers can leak and run down the block and then spread along the oil pan giving the appearance of an oil pan leak.

 

[Bee1971]

I had a timing chain cover leaking oil once , the oil would flow back on the oil pan ridge and gaskets

Here the alignment pins didnt fit well in the factory timing chain cover holes pushing or dimpling out that area when it got tightened down after a camshaft change and not sealing

Dont ask me how many times i had that 402 Oil pan off before i finally got under the running engine after everything was perfectly clean and dry
