Here's a quick how-to on changing an oil pan gasket on a 302 without removing the engine. It's the same steps as changing a starter more or less, so it's basically 2 birds with 1 stone.

First, raise the car to an appropriate height and support it. Remove the (-) battery cable from the battery.

Pull the mounting bolts from the rack and pinion. You're not going to remove it, just manipulate it so it's out of your way. In my case, I lifted the right front tire from the pedestal it was on so that side would turn freely.

Remove the cable from the starter.



If your car still has the secondary cross member bolted in place, remove it. That gives you access to the bottom starter bolt as well as clearer access to the back oil pan bolts. Remove the starter by removing the 2 bolts holding it in.

Remove the sway bar bushings and brackets from the frame and let the sway bar hang.

Remove the oil pan bolts and remove the oil pan from the car. I had to wiggle it over the sway bar and out of the car.



This picture is to illustrate the difference between a II oil pan and another stock front sump pan. I also have a picture of the part number for the oil pan. I'm not sure if it's the complete part number or not, but what I have is still visible. The II pan is behind the standard.





Installation is the reverse of these steps. I purchased the newer one piece oil pan gasket which comes with threaded plastic retaining clips, they're extremely helpful for reinstalling everything.

I like and also recommend the one piece pan gasket.

Just got back from a test drive after adjusting the carburetor with the A/F gauge (https://www.stangnet.com/mustang-fo...-holley-4150-tuning-exhaust-escapades.915742/) and so far I have no leaks anywhere again!

Hello Lilcbra

Does the front oil pan not fit at all?
I can't get my originals tight and bought the front one.
Does only the original oil pan fit?

You'll most likely run into clearance issues with the rack and pinion. It may fit without modifying, but it's unlikely. You can shim the motor mounts up to accommodate, but you may then run into hood clearance problems.

You can lift the engine up about 3/4" with spacers without clearance issues as long as the engine is running the stock manifold or similar with a drop-base air cleaner. It's when you get into mid-rise intakes like your car and mine are running that things get... "interesting".

I'm wondering why your MII oil pan doesn't seal? I always thought with silicon sealer it will not leak...
What gasket did you use?

Nope. Just the steering coupler, the 2 mounting bolts, and the tie rods and it's out. Easy peasy!

Rolling through this thread again since it was recently referenced for @78 Mach1 and noticed I never replied to you @extra_stout - sorry about that! The reason I changed the gasket is that it looked like it was leaking from around the front seal area. I wasn't sure why it would've been leaking there from the oil pan, but I decided to go ahead and try swapping the pan gasket anyway. But I mentioned this in the carb tuning thread -

- I replaced the front seal and installed a harmonic damper repair sleeve at roughly the same time I did the pan gasket. I guess I figured I'd make sure that I covered all of my bases since I did all of this at roughly the same time. The good news is that I've not noticed a leak from that area since then!

Anyway, I just wanted to let you know that I wasn't ignoring you since I never responded. My apologies.....
