Oil Pan Gasket help!

[BroncoBub]

I have searched this topic on which gasket to use and purchased this gasket (FEL-PRO OS 13260 T Oil Pan Gasket Set) and it is leaking in the front and back and on the passenger side toward the middle. I have torqued it to spec and still leaking. Its the original 75 Bronco oil pan I'm am using and the engine is from a 95 5.0 truck. Is this the right gasket? or Should I go a different route? I guess my question is should I be using the gasket for the 75 or for the 95?

Thanks, Bub

So no one has had issues with the one piece gasket?

The only issue I have had with one piece fel pro gasket on my 77 is the front in the back corners I put a dab of RTV on there on my 76 bronco 302 but it's a 1990 engine same gasket I think almost no leaks . Somebody on here said if it's not leaking it must be out of oil

I also put a dab rtv on the corners with no success.

I used a Felpro 1-piece gasket on my 351W and it works fine.
The best part is the little clips that screw into the block that hold the gasket and the oil pan so you can install the bolts easily.

Your pan rails could be bent. Worth checking into with a straight edge.

Always clean, clean and when you're done wiping every square inch with alcohol, clean it once more- I'm being serious here.

I hate leaks and won't put up with them. I dont have any leaks on my Bronco.

You really have to clean any area that will have a skiff of RTV. I'm sure I clean gasket surfaces 10x better than I've ever cleaned the body or windshield.

Thanks I'll check the rails.

One piece gaskets may be ok for newer engines, but I'm not a fan of the one piece gasket on old engines.
The problem is that saddles and side rails need to be made of different materials so they can compress properly.
I prefer cork, and mine have never leaked.
I put it in the same as I do valve covers. Contact cement or weather strip adhesive on the pan side, and a light coat of wheel bearing grease on the block side. Only use RTV in the corners, and just a dab.
Don't overtighten the bolts.

Whatever you do, whether you're using a one piece or cork set, don't put RTV on the side rails!
The gasket can squirt right out when you tighten it up.

Thanks blubuckaroo: I think I'm going that direction..

Isn't the rule of thumb that the 1 piece is for oil pans that are smooth, and cork are for oil pans with groves along the sealing surface?

I have grooves on the sealing surface of my oil pan. It's a PIA to find anything now a days because the local part stores don't stock anything where you could look at it cause it would have to be a flat gasket to seal.

Oh wait, cork is flat...sounds like a good rule as I'm looking right now and getting frustrated looking for the supposed, "better 1 piece gasket". The on line parts places are using the same picture for several items and the prices range...why? The descriptions suck.

The 60 year Phil tries not to screw over the 75 year old Phil where he has to redo an oil pan gasket down the road.

Why wouldn't you just use the '95 pan & gasket? It would fit exactly like this '88 pan:

I used the felpro single piece gasket with success. Are you using the 5.0 oil pan reinforcement rails? They fit the 302 pan and work as intended. Its common for the 302 pans to get over-torqued and deform the pan at the bold holes. Take the pan off and check the holes for any deformation. I suggest getting a set of rails if you dont already have them.

Rails? I have my passenger side dipstick pan off now. Cork gaskets arrived today. What year oil pans can I use for my 1979 302. The engine is in my 1973 Bronco.

The krinkle paint from the "Bronco by Ford" valve covers was on the underside in the mounting surface of the valve covers.....probably the source of my oil leak.

Thanks for the info guys.

I reused the stock rails that were on my 2000 Explorer 5.0 doner when I swapped it from my 1969 302.

I believe that all 289/302 Bronco pans will fit but it must be EB specific. There are aftermarket options from the various Bronco part suppliers.

I love those things. But at almost 100 bucks… Wow!
Since they are Ford racing I thought we should bring those in for the bronco crowd. Not too sure how many would be takers though.
Although anyone who ever had distorted pans leak, would be a huge fan too.

It was stock on my 2000 explorer junkyard motor. That Ford Racing link was just to show what I was talking about... Should be able to get it much cheaper.

I'd just go pull a set from the junkyard if I needed another pair.

Weren’t a lot of explorers the last time I checked, but it has been a while. And it was only on the steel pan, correct?
Good thing to grab for sure.
