Seafoamed my 1996 LSC... video

[turborich]

Well, I guess that each person's experience with seafoam is different. I personally saw NO noticable improvements. Idle isn't any different or smoother and mileage sure didn't go up in my case. Who knows, maybe it's genuine stuff when there is a problem or maybe just snake oil???

Haha pour some oil in your intake and see if it smokes. Yeah my guess would be that the smoke is mostly the seafoam itself.

Done properly, the seafoam will not smoke but very little by itself. For a high mileage car, there is tons of EGR/PCV sludge buildup in the intake, especially in the secondary passages of the four cammer. Many vehicles will take 2, 3 or more treatments with seafoam to effectively clean the induction system.

Seafoam is good but Auto-RX and Amsoil engine flush are better.

Cough *snakeoil* cough.

FYI - I had my induction system cleaned 'commercially' after I had previously treated it myself 3X's with Seafoam, the third time receiving very little smoke feeback.

The techs hooked everything up (BG products?), and were telling me what to expect... big smoke cloud, better performance and mileage, yada, yada, yada. When they were done they were inspecting their equipment for a malfunction since virtually NO smoke resulted from their treatment. They talked themselves into a 25% discount and I went on my way feeling assured the intake was as clean as it was going to get without physically removing parts and hot-tanking them.

Is there a how to thread on this? how many times can you do this thing?

Seafoam is much better than GM cleaner..............

It's easy to use, you just pour it through a vacuum hose like the brake booster. The can says you can add it to the crankcase and in the gas tank, but I really don't think it'll do anything there (maybe help a ticking lifter or something, but not on our cars.)

I still maintain it's pointless on an engine that doesn't have problems. I also maintain that GM Top Engine Cleaner available at any GM dealer will work a lot better if you do have a carbon buildup problem.

BTW here's what's IN Seafoam:
PALE OIL .01 68 40-60%
NAPHTHA 10 68 25-35%
IPA 33 68 10-20% (This is either Isophthalic Acid or Isopropyl Alcohol)
CARBON DIOXIDE 38650 60 3-5%

You can also use transmission fluid followed by water. That is how we did it back in the 70's. Half a quart of transmission fluid followed by 8 oz's of water. Never had a problem with carbon in any of my 70's muscle cars. Seafoam is not snake oil. It has been around a lot longer than GM's crap and is trusted and recommended by all of the off shore racing boat manufacturers. Go to any off shore racing event and you will see cases of this stuff in almost every pit. Simple answer is that the stuff works. Not only at removing existing carbon deposits, but in preventing future deposits.

I think Im going to get a can and see for myself.
