Cleaning a 4.0/Aw4/NP231

[cody.quattlebaum.16]

So, any tips on the best way to clean a motor/trans/transfer case? I want to clean mine up before installing it into my MJ. It has a ton of grime all over it.

 

Also, where does everyone get their gaskets? I need to replace most of the engine and trans gaskets. Rock auto?

When doing my swap I used a stiff brush, a pressure washer, and a whole lot of purple power sprayed on at full strength. Came out really well, I had to repeat the process a few times.

For gaskets, use Fel-Pro permadry wherever possible. They're more money but will outlast the rest of the vehicle and not leak a drop. RockAuto, Amazon, eBay, I buy from whoever's cheapest with shipping.

I used purple power and dawn dish washing liquid. Dawn works wonders on oil and grease.

Yep, all the above.

 

I use mineral spirits in a cup gun and use it like a mini pressure washer.

 

I also use Gunk Original.

 

Dollar General sells a product called Awesome that is $1 per spray bottle.....works great......you can't even buy a spray bottle for a dollar.....

Diesel makes an excellent parts cleaner, and it's relatively cheap.
