Hey All, So i ran seafoam in the gas tank and now my temp gauge doesn't go above 150 what happend? It's a aftermarket gauge since I replaced the dummy gauge when I first got the Jeep. The aftermarket gauge worked fine until I ran the seafoam. Anybody know what's going on. Thanks

 

did anything get loose with the gauge? i ran seafoam through my rig and it worked great put a little in the intake,oil and tank

 

I think it just might be a fluke and the gauge just went bad the same day I put seafoam in it.. Cheapo from Advanced Auto. I'll get another one and check that. Thanks

 

Oil is a no no

 

you can seafoam the oil (crank case) so long as you change the oil within 300 miles afterward.



get rid of the crappy aftermarket gauge. junkyard trip, cluster, oil pressure and temp sender, done.

 

It tells you to add some to the crankcase

 

And Im telling you to jump off a bridge, will you?

Read and learn.

 

I'm telling YOU that seafoam has been around for a long time, and been used in crank cases with no ill effects for a long time.


the ill effects of sea foam are when some idiot just pours it in and doesn't do an oil change right away.

 

Wheres your evidence? Seafoam is petroleum based, that will sit on top of the oil and thats the first thing the pump is going to suck up. Your bearings will hate you and so will everything thats getting foam instead of oil.

 

Doesn't the oil pump draw from the bottom?

 

yeah...the sump is not at the surface of the pan.

the crankshaft turns and churns up the surface of the oil, plus the oil does what gravity tells it to and mixes back on top of the oil, thus mixing the seafoam in.

pretty simple...although I do agree that it is something that should be run through and drained immediately.

 

Right below the mid point

Im not a fan of the whole air pocket thing that takes place

 

That's not correct either, none of the crank is in/submerged/touches the upper oil level. The oil pump pick-up is located down low in and just off the inside bottom of the pan.

 

yeah, I actually just went out and was looking at my torn apart 4.0 to verify that.

reguardless, the sump being located low means it sucks from the bottom. oil from the bottom gets pumped through the motor, and drains back on top, mixing fluids if you put seafoam in. you wouldn't ever suck ONLY seafoam.

 

Your not taking into account how much oil is in the engine when its running, you would get some sucked through before it mixes.
