What's everyone doing for oil pan replacement? I take it not the thin oem? Moroso, Big Iron oil pan, Dorman? Why did you go with it? I'm leaning towards Big iron as it has the welded in dip stick tube. I just want something that won't rust through so easy. Mine is original but in areas I see where if I a rock were to bounce up and hit it right it would puncture.

 

There is another member her that puled his to do some work and replaced his pan with a Big Iron. I think he is happy with it, even though he's still working on things and hasn't gotten it back in yet.
I recently saw another member that plans to do a Moroso. I've never had an issue with the OEM pan, so I can't help

 

Seems it partially depends where you live how long the oil pan lasts. My truck has a leaking timing cover planning on to replace with an oem while the motors out. With so many supplemental parts to replace when pulling the engine the oil pan will be one of the first purchased. Then I can use marine paint and put a decent amount of coats on with more than enough cure time. This type of paint has additives to resist salt degradation. Although hopefully any day now the RiffRaff billet oil pan is coming out lol

 

Thanks. Maybe I will go with oem and Por15 it. The only other issue is that oring on the dip tube receivers that swells and leaks after soo long. I'll be looking for a fix for that if I go this route. Thanks all!

 

Yeah I'd want to nip that potential problem in the bud while I had the chance. There's always the nuclear option. For those that are all about that BLING.

I went with the Big Iron pan because it’s simply the same cost or cheaper than an oem + weld in dipstick. Motors not back in the truck yet but the pan seems to be good quality and the customer service was top notch when I called them.

I forget who it is off the top of my head but he’s done a bunch of them and likes spectra plus the weld in flange (which is cheaper) and gets them PROFESSIONALLY coated with bedliner. I have not coated or painted mine “yet” but I figured the oem one made it 20 years in the rust belt, this one will last long enough (that and the fact that my local bedliner/undercoat place is a bunch of halfassers).

 

What are your thoughts on the big iron. I was looking at those as well.

 

Heads up on POR15. I did my e99 frame with that in 2014. I've put up my fair share of industrial coatings over the years so I understand and appreciate the prep part of the POR15 program. Long and short, I had a hole rust through the frame. In 8 years - in northern Maine. Once micro-cracks form, it is game over. Rust will develop and spread under the hard skin of the POR15. My first indication that something was amiss was a postcard sized piece flaked off, revealing a major soft spot at the forward spring perch under the bed.

Granted the oil pan doesn't flex and move like a frame, but it does thermally cycle quite a bit - which could introduce micro cracking.

On my '02 I have a Moreso that went in Nov '22 (during a clutch replacement; truck lived a few years in CO, then the rest in AZ before I got it; there was some rust on the pan; enough that I felt compelled to put one in). I also sprung for that big blue gasket. I just noticed the slightest of slight weeping at the crank part of the pan, which I think a check on the bolts will likely take care of (now that I think of it, I never did check bolts a month or 2 after the install). I have switched over to a lanolin based product for rust prevention. I had some put on the pan, but that is a tough environment to keep something on, especially the lower corners.

Back to the e99: it lived in northern Maine all it's life. I got it at 15 years old, and replaced the oil pan 2 yrs later (clutch job). The stock oil pan did have rust that I was closely monitoring. But after the pan was down and I could check it out, it wasn't nearly as bad as I was thinking it was. I replaced it with a Moreso and after 6 years it didn't have any rust to speak of. On that, the Ford sealant was used. It always weeped a little bit (at the crank mostly), but nothing that made it to the ground as drips.
