Seafoam does not hurt anything.

Period.


The only problem is when it knocks loose the built-up **** and reveals leaks or the sludge clogs something.

I run a can through each car about every 6 months. If you put it in your oil, don't drive more than ~150mi before doing an oil change.

 

Thats exactly the issue. Knocking crap lose. Hence if you dont take care of the engine. Op can always use gumout and use the mopar tool to run it through the injector

 

Got a 89 with the straight six

Does anyone know if I need to use a different belt if I'm installing a a/c bypass pulley?

Also would I be better off just using a shorter belt instead of the bypass pulley and if so by chance does anyone know the length?

 

Belt should stay the same.


I wouldn't just leave the AC out of the system. Might not get enough contact on the alt or fan.

 

It's an AC compressor delete pulley/bracket. It just takes the place of the compressor. Uses the same belt.

 

Can it affect the cat' in any way? - Not trolling, just curious enough to ask, but not nearly enough to search lol.

 

seafoam works wonders and I love it but it can knock sludge and such lose on older dirty engines which can clog ports and valves and mess up seals

 

Which is why it will never make it into my 91 with 314k and poor service record (none) lol

 

When I seafoamed mines I had a great service record and previous owner did a port cleanout probably 100k prior

 

yea... got mine with 294k and an ashtray that had never been cleaned. I think the oil had been in there long enough to turn back into a t-rex.

 

Anyway to help break my o2 sensor loose? I've sprayed the crap out of it with wd40 and tried knocking it lose with a mallet, not been a budge.

 

Try letting the Jeep run for a while and get it warm then try?

 

Wd40 sucks try pb plaster, and try to get it out after the exhaust has been at running temp.

 

Good idea, ill go do that.

 

WD40 is for lubrication and water displacement.

Use PB Blaster or a similar penetrating oil like Seafoam Deep Creep, Liquid Wrench, or Kroil.
