seafoam

ok your the pro nothing gets past the upper rings. should have used my head

Im not saying Im a pro but putting it in the oil cleans the rings more than putting it in the brake booster line.

Just did a seafoam treatment on my B2200. It has 120k on the motor. I was having some idle issues and after doing the treatment it works 100% better. Definately worth a shot.

FYI, when I pulled my motor apart with 168K, the top rings fell apart. On a motor with that much on the clock, the rings are pretty worn and it probably as a bit of blow-by so what was said about carbon helping to hold rings together is completely true.

It also depends on how well your motor was taken care of. On my mitsubishi I had 210,000 miles on the original motor, tore the motor down and the rings were fine.

Right. I should have said what I read is all the crud that comes loose and is blown out the exhaust may not be good for the O2 sensor. Since the O2 in my truck was replaced last year I will most likely put the old one back in before doing a treatment. May not be necessary but that new O2 sensor was an expensive bastard and I want to be safe. Looking forward to more replies about Seafoam treatment results.

Now that I will fuss with you about I doubt it will hurt it but if you got the old one a quick swap to be on the safe side makes since to me

i used 2 cans of seafoam on my gastank in my 92 (which sat for 5 years and had like 1/4" thick layer of varnish in the tank) well i let it sit for a day then sprayed it out like 10 times and let it dry out... put 5 gallons of fresh gas and 1 can of seafoam in it and it fired up... really rough at first but once it started idling correctly (after 15 minutes or so) it ran great.
