Seafoam...

Anyone know anything about Seafoam. Is it actually a decent product? Would it benefit an old engine, would it benefit newer cars as well? Any dangers with using it? Will it smoke out my neighbourhood?

I'd be hesitant in using it in newer car due to the various make up of O' rings and seals in the FJ systems, some of these chemicals can attack the injector O'Rings.

i use it and no problems, i consider it a italian tuneup, add a can and drive the piss out of it.
evidently it is popular at my car store, it is out of stock often.

Used it on my boat for years as both a cylinder fogger (aerosol) and gas treatment between seasons (along with Sta-Bil).

Most of the boaters in Rhode Island swear by it.

It's very popular with the Porsche crowd. If you go to www.pelicanparts.com and do a search for Seafoam, you'll find that it's used quite a bit in Porsche engines with carburetors and Fuel Injection. I've used it in all my cars with great success. If you pour it down the carb, it will smoke some but all you have to do is put it in your gas tank.

I've seen it at local Autozone.

We have a home made turbo set-up on one of the drag engines and have added Sea Foam to the water injection system with great results. It's kinda of a magic panacea for engines.

As a quick aside, spraying windshield washer fluid (the Winter formula with alcohol added) is a great way of de-coking the valves in a VW engine. The water/alcohol/soap/heat combine to clean the valves, cylinders. piston tops and intake runners wonderfully. It's really weird to remove the heads on the turbo engine, the combustion pockets are pinky piggy clean.

"pinky piggy clean"?????

Hamm, from 'Toy Story', might take issue with that remark........

In his best "Bahstan" accent, too, I might add...

Used it on my old Sporty's,CBX,KZ900,and all sailboat engines and dive boats. Sometimes it truly werks wunders.Mystery oil is good too!
