If seafoam works in a 500hp Buick 350 (1971- pre-"common block") without catastrophic engine damage, I think it should work alright in a 4.0 Jeep... Just sayin from experience...

Sorry to jack my own thread but i just noticed I didnt spell seafoam correctly in the title. Now back to the oil seafoam, dead dinosaurs and velocity. Sorry for the jacking.

Well I'm going to use the Seafoam thing in my oil soon. I'm running almost 80 psi, it jumped up after an oil change. I recently bought the xj it was wrecked needed new rad, an condensor fan. I hope the foam works I cant afford A tear down right now, the Chevy crapped out. I'll let yall know how it goes.

My opinion to the original question is......it's purely coincidental that the gauge stopped working after Seafoam was added.Originally Posted by mwdouglas
Cherokee 91 isnt it amazing how one question can lead to so many opinions lol

Have you tested your oil sender to confirm that it is working correctly? Pull the connector off and see if it drops to zero. Then ground it nd see if the gauge goes high.Originally Posted by 7jeep

Seafoam works good. And yes you CAN use it in your crankcase without changing it, but it is petroleum based and can cause damage. I do not run it for more than 1000 miles MAX. Usually a few hundred at most. If I run it BEFORE my oil change, I put 1/3 into the crankcase, 1/3 in the intake thru the BB hose while running and in my tank.
MMO is cheaper for using in the tank tho.

Just to add my .02 Bob the oil guy didn't use any real type of uniformity in his test. Yeah he showed the before and after of the same oil using lucas but where is the control? Whats the deal with using only the schaffers in the left tank and, changing the brand used in the right tank when going from gear oil to engine oil? Also for the first test shouldn't BOTH tanks be the same viscosity? I'm not an engineer by trade but a redneck engineer by hobby and this "Just Don't Sit Right" And while I'm not saying seafoam is bad or good but isn't it a little odd that something that can be used as an additive for fuel which can be highly corrosive under the right conditions. i.e. nitrous when used in gas engines as a performance adder is highly corrosive/caustic. Nitrous used only as an example and not actually realted to seafoam in composition) can be placed into the crankcase and passed over around under and through bearings and all kind of sensitive surfaces and not cause any damage? Maybe not right away but long term!? Just my .01 but anything that can be used as a snake oil seems well like snake oil.

Doesnt mean you know anything about cars. Than make your own test. It is not one guy coming up with these tests, they have engineers, tribologists, chemists, and oil analysis professionals who come up with these tests and confirm them. Their degrees and experience make you look like an idiot.Originally Posted by dilljeepo
I wouldn't trust "Bob the Oil guy" over an international company whose website says that their product will not ruin your engine, that's huge for a company to declare, especially today when everyone and their dog wants to sue some company for money. Also... someone said there's bubbles in the oil... what happens when you put black vinegar into clear water and shake it excessively? The vinegar/water solution turns an in-between color. This is because it mixes... the same way seafoam and oil would, and once it's kicked around a lot in the engine it'll probably change the solution's color too...... air bubbles?... I doubt it. yeah sure it might change the color of the oil because it's clear and your oil isn't, after your engine sits it'll dissociate again, and your oil will change color. Why is oil black? because of detergents and **** that pick up carbon deposits (that happen to be black) that sit around in the oil, they're not actually part of the oil. My parents (now retired) are both professional Mechanical engineers and I'm in my third year, majoring in Chemistry and Biology...We all use Seafoam in the crankcase every once in a while. Seafoam is fine to use in engine oil. Don't trust "Bob the oil guy" he's full of garbage.

It is likely that the problem is in the gauge circuit, all engine oil pumps have a pressure relief valve which bleeds off excess oil when required to keep the oil pressure at a reasonable level. If the valve gets stuck or blocked, oil pressure can quite happily build up so high the oil filter will rupture, and all your oil will be pumped onto the ground.
Check gauge, sending unit.
Edit- DJB, girlfriend made plans for last night. Picking some up today after work to complete the test. Will be doing it with a 10W.
