I am in the process of building a stroker out of my 4.0 in my 87 Laredo. I haven't pulled it yet. I'd like to get some input on the best way to de grease the engine. Im thinking brake cleaner......alot of it. I want to do my engine bay as well. My block has the usual build up of grease, dirt, burnt on oil etc. My overall plan is to leave the block clean, not paint it because this Jeep is a daily driver for me. I did hear recently that simple green is a good cleaner for this kind of thing, but I don't have any expirience with it. Suggestions?

 

if there is alot of junk in there take it to a diy car wash. some places dont have it but it might. is the wheel/engine cleaner. its a degreaser that sprays out of the pressure washer. it works pretty well for the big stuff. then you just spray it off. then for the more detailed wash i just used bbq grill cleaner.

 

Are you talking about washing it inside the car, or after it's been pulled? Because if it's inside the car, how would you keep from getting cleaner all over the wires and sensors and any other places it doesn't need to be?

 

when the engine is hot and running and you wash in the "DIY" car wash, It usually seems to clean better, especially if you rinse before using the chemical.

Purple power has never failed me though. when you have it on the engine stand, a rough rag, putty knife and some patience works well.

 

If you go to Walmart and go to their automotive section they have a product there that is specially used to degrease your engine. Works like a charm.
Best of luck!

 

Simple Green

 

x2. Simple, effective and environmentally friendly!!! Works better than anything else I've ever used.

 

diesel works great for loosening up the big stuff if your not a tree hugger anyway

 

outside the Jeep of course. My headgasket is blown anyways.

 

Thanks for the suggestions Question about the simple green though. I was told earlier today that after using simple green on my engine/engine bay I will need to blast the cleaned area with brake cleaner or degreaser to get the residue off? It sounded like BS to me, but...that isn't true is it?

 

Simple green is the best.
NO, after you let it sit for a bit, just hose it down and wipe it off with some clean rags.

 

No, just rinse it with hot water.

 

i use some stuff called grease off its made by a company called knights they also sell spray nine . both of these work great another thing i used to use is oven cleaner if you know somebody with a steam cleaner works great to . no cleaners involved.
