I usually changed my oil 200 miles after I put seafoam in it.

I hear you're not supposed to put anything in your oil...IMO its a bad idea for anything except your gas tank...just use high quality oil.

I wouldn't even put it in your oil. It thins your oil now why would you want that? Just change your oil. I used it through the intake and put it in my gas tank. That works in my experience. You gain some throttle response back, some MPG and idles better.

Same here, though my engine was pretty clean to begin with so I didn't get the bellowing white smoke...it improved a little bit

I used it because I know Seafoam is a great product and have heard good things about it. My ZJ has 213k on it and figured it could use some cleaning then fixing if any oil leaks pop up. Currently have to change the oil filter housing O Rings next oil change so guess I'll knock that out today rather then waiting for a Lil bit.

How do o go about putting it throw the intake. Have always just used it in the gas personally. Only reason Why I'm trying in oil cause I've heard it cleans the internal really well that way. Know one person was saying after they used it a few times in oil there oil would be clean for oil changes after he did a cycle like newer cars usually are

I put Seafoam in the crankcase for the first time Sunday and then change the oil Monday morning. It does thin your oil some, but that is one of the reasons why you do not run it for a long time, I only ran mine about 70 miles. It cleaned it well and never did cause any leaks. The air intake hose is usually removed and then poured slowly in the throttle body while idling for about 1/3 of the bottle contents. Then you turn it off for a few minutes and then start it up and watch the smoke show.

Same here... 218K miles, just seafoamed the engine for the first time per the directions. No problems since and it runs much nicer. Just changed my oil after 50 miles running in the crankcase, then I changed my plugs, cap, rotor, wires afterwards since they needed to be changed anyway.

Ran a compression test after I changed the oil and read between 150-175 on all cylinders in my 4.0L engine.

In the "olden" days of leaded gas, we would run a quart of ATF for a day in the oil before a change. The high-detergent level of ATF would clean hell oughta the insides. On the other end of the spectrum, I would see diesel mechanics run a quart of diesel fuel in the engine for a minute, then drop it out.

crankcase's are made for oil, you should not have to play home chemist if your oil is not doing what you like than get a type of oil that does.

The best way to clean your engine is to run a HM or HDEO and let it clean over time.
I persoanlly run Rotella T5 10-30, It's rated for gas or deisle, it has a high dtergent level, an add pak that is equal to a HM oil, and HDEO's alway produce better ware numbers on a UOA, also if you have the 4.0 HDEO will give you a much neede healthy dose of zinc and phosphorus.

I C you do have the 4.0 after your SF run you should deff. switch to Rotella T5, your 4.0 will love this stuff, HDEO's produce better numbers in a 4.0 tahn anything on the market, thats a fact. best of all it's only @16 bucks a gallon at WM

Just did the oil change and had to change out the housing O RIngs and DAMN that torx bit sucks to get off but finally did with a big pipe over the wrench. Bad thing is i got the wrong O Rings but was able to change the main (large) O Ring gona keep an eye on it and maybe to the smaller ones later.

Bad thing is tho this is my second oil change in after buying this Jeep and my oil pressure is slowly getting lower (jsut under 40 driving at 30 on idle) and i have a small rod knock so quessing its going to be time to rebuild her before she throws a rod.

other than the obvious (a rebuild),
I would say Rotella triple T 15/40 would being your oil PSI up a little.

We still fill up filters with ATF on the cummins during a service.
