Seafoam Advice

**Kjz99z28** · 08-01-2007, 09:05 AM

I've been reading a lot about using seafoam to clean things out. It sounds like a great idea and I'd love to try it, but I've heard a few things that have made me a little wary about using it on my car. I figured I'd ask you guys cause if anybody knew.. it'd be you!

I heard that seafoam will do its job and clean everything out, but that it may not be a great idea on an older car with higher mileage because the "junk" in my engine may be keeping things from leaking. I was warned that it might create problems because of this.

My car currently runs fine, I just wanted to help it out a little. I just rolled over 90K miles.

I take great care of the car.. but I've only had it since 70K miles, and I have no idea how it was treated before me. Should I bother trying it?

Sorry.. this was a little long.
CLIFFNOTES: My car has 90K miles.. should I use seafoam or will it clean the junk out and give me leaks?

Very true. I guess I should think about that

DO NOT USE SEAFOAM!! I will clean out your combustion chamber yes, BUT it will also eat away at any rubber gaskets and seals that it come in contact with whether its in liquid form or gas form.

Here is what i suggest:

Talk to a GM mechanic or a really experienced person on what kind of fuel cleaner they recommend to clean the injectors. Every manufacture likes a specific brand. Run that in your fuel system. At the same time replace your fuel filter with OEM or better.

Take off your intake and throttle body, use brake cleaner or carb cleaner and get all the gunk out of your intake and make sure the throttle body is lubed.

If you have a MAF, take it off and use the CRL Mass Air Cleaner from the parts store. Clean it out making sure not to physically touch your sensor on the inside, but wipe excess away from inside with a rag.

Change ALL your plugs! Even that horrible one in the very back.

Then its just checking your plug wires and all fluids. I would suggest flushing your tranny if you havent in 50K miles. Autotragics need that kind of attention in order to last. Especially on high performance vehicles.

Hope this helps

Go for it but only if I can watch when you start it!

I have always been a fan of SeaFoam. As long as you don't keep it in longer that say 2 hours, everything should be fine including your seals. There is a sticky on ls1tech that has pretty much everything about SeaFoam. You should check it out. I know lot's of people that use it with no problems. Though, my friend kept it in there over night in his 200,000 + chevy truck and ruined his cat's

I actually know of a guy that used it to pass smog after a 1 hour SeaFoam clean. +1 for SeaFoam

I'll have to look into that one, thanks!!

check out the stickies in general help

There are guys who have used SeaFoam for years and swear by it, same with Marvel Mystery oil and any other aftermarket additive. Best thing to do is ask questions, read the stickies (LS1Tech has a few good ones too). And it certainly won't hurt to ask a GM technician (not the oil/lube jockey) who knows his shit what he uses, THEN make your own choice, not everyone has a good experience with every product. I tend to look for stuff that has the Least negative feedback. Not the one that ONE guy swears did the trick. It's time consuming, but then again, so isn't swapping in a new engine..just my opinion.
Good Luck
and I have had good experiences with Sea Foam. As well as almost any product CRC makes..

My One Auto tech teacher(A Master Tech...) Had us using Seafoam in class one time. I had used it in other cars before hand and i swear by it. im doing mine again once i get it running.
