Oil Pan Gasket Question

I am helping a friend out and came across a situation. He has a 75 SBC with a stock Z28 oil pan. There are 2 fel pro gaskets available. One is 34510 which is set up for either side dip stick. Then there is 34509 which is set up for only passenger side dipstick. The 34509 is different where it goes around the back of the motor with 2 little blocks that look like they would fit into something. Any idea which gasket he needs?

He needs a one piece oil pan gasket.

Re: Oil Pan Gasket Question

both gaskets mentioned above are 1 piece. They are different at the back of the gasket.

Re: Oil Pan Gasket Question

First I will say being a '75, you will need to ask for the late model gasket (one piece you are working with) as not only you will see differance with the dip stick, you will see differance in thickness of the front pan seal, one thin , one thick. 1957 -1974 uses a 34509T and 1975 -85 used 34510T.. the latter is what I used , cutting off the outside pan lip seal for right hand (passenger) dipstick blocks.
The little blocks are necessary, they fit into the block next to main cap. I know it says dont use sealer but trust me, apply a dab of sealer in each corner front and back ,and it would not hurt to apply a smear of RTV on each side of the rear pan seals. Been there done that , twice.

Re: Oil Pan Gasket Question

It is a 75 block but it has a 69 timing cover and oil pan. Does it make a difference?

Same problem I got into, thats why you need the 34510T, Thicker front gasket than 1969. If you used an early style pan like 1969, you would use the other. Problem is not in the timing cover, its the pan front lips.

Wait , read your post wrong, pan is a 69? block is 75. My error, I thought you said pan was 75

Re: Oil Pan Gasket Question

if that was the case, 69 pan, then you need the other 34509T, sorry. I misread. Either way, on a one piece gasket, you have to cut off what you dont need or if its not in the way, leave it.

Re: Oil Pan Gasket Question

But it is the back of the gaskets that are different.

How? the little blocks? Let me look at my gaskets and see if I can see the differance. Get back shortly.

Ok, I don't see any differance in the rear sealing portion of either gasket. Its the front that is differant on each. One thick sealing area and the other thinner.

Re: Oil Pan Gasket Question

Here is a pic of the back of the 34509 gasket, you can see on each side the protruding blocks. The 34510 does not have them.

You have to have those blocks to lock the gasket on the main cap to block surface. If they are not there, take the gasket back . If I understood you correctly, your pan is a 69, then you need the 34509 gasket. The only differance between the two gaskets, is the front pan sealing area, one has thin seal and the other has a thick. What ever gasket fits your pan, you do need those rear alignment blocks. Both my gaskets have these. Does your block have these little pockets?
Anyone else see this differantly?

Re: Oil Pan Gasket Question

There is a little pamphlet in the package that describes the function of the blocks. Read on.

Don, I don't think that always holds true. My block is a 71 and I had to use the 34510 with the thick front seal. It is definately the right one because it's already installed and it sealed and fit prefectly.

The OS34510T does in fact have those tits sticking up in the rear. I just bought one and installed it. They seat themselves in the rear main seal cap. Both gaskets have them.
