Hey guys, well I've been planning on seafoaming my 94 Jimmy tomorrow but my dad insists that I don't do it. I've researched it a lot and don't seem to have any problems with it but he thinks I'm gonna blow up my engine. And I read a youtube comment on a seafoaming vid somewhere that said that you might hydrolock your engine(and bend connecting rods) if you dump the stuff in through the brake booster line. However that's the only "risk" I heard about seafoam. Is this true?

 

Speaking from only my experience, no, you will not damage the engine. I've done it more than a few times on a few different vehicles with absolutely no adverse affects, let alone blowing up an engine.

 

Thanks! My dad thinks I'm 4 years old or something when it comes to car stuff . Anybody else got any responses?

 

Same as AJ, speaking only from my experience, I did it to my blazer and the Wife's Explorer. Didn't bother with booster lines or dumping it in the tank: i went straight through the throttle body. Other than running the risk of fouling your plugs (possibly) and needing to get an oil change after seafoaming, you should have no problems.

There are also a number of how-tos on here if you search for them

 

I'm with these guys. I have used it in a lot of vehicles with no negative effects, through the brake booster line and down the throttle body. I don't bother with the gas tank or the oil, I use Lucas for that stuff.

 

Ok well I seafoamed my S15 about 20 minutes ago and it runs fine. Even better than before actually, better throttle response, feels like its got a little more power, and the idle is a bit smoother (but not perfect, but I think I need new spark plugs anyway). Not so dangerous at all! lol

 

another convert!

 

hahahha yep!

 

Hey for you guys that have seafoamed, you put it in the tank, oil, and vacum, do you have to do all 3 at the same time, or can I do the oil and gas, then some other time do the vacum, will that effect how well it works?

 

I don't see why not. Just make sure you don't put more than 200 miles on the oil with the seafoam mixed in it.
