Hi, I have a 3.4sfi 1994 camaro and i was just wondering what vacume line to use to poor the seafoam into? Pictures would be nice. Thanks, B.Berg

 

ahhh. i personally dont suggest using seafoam dude. Unles you have mad miles on the car. Ive heard some pretty bad stuff about sea foam and what its done to cars, but i have heard good stuff too. But i would recommend just pouring half a liter of automatic transmission fluid into your motor( with all the other oil ), and then drive it around for 20 minutes. automatic transmission fluid has great cleaning detergants in it. then change ur oil back with pure engine oil of course.


but if you go with sea foam, i have no idea where the fuel line is cuz im a carb guy/kid lol. if u do use seafoam dont forget to put some in the gas tank and engine as well.

 

Any small vacuum line will work. Just don't use the one attached to the fuel regulator. Be careful and bubble the seafoam in slowly, you don't want a liquid lock while the engine is running. I've used it many times in many different cars and it works wonders. Be prepared for massive amounts of smoke. Best to do it at night.
P.S. change your oil right after.

 

did it to my buddies stang with he 3800 series v6 we just used the vacuum line on the brake booster.Seems like we put it there, and the crankcase, then changed oil. There was a crapload of white smoke. even if it didnt do anything it was worth the ten bucks just to see all the smoke lol. But I would recommend the brake booster just make sure u put it back on

 

I used the brake booster. Seafoam will definitely liven up an old engine. Just be prepared to see tons of blue smoke if you have a significant amount of build up lol.
