Traded my 93 in for it. Its got 87k miles on it... was wondering if I should seafoam it or not? I highly doubt it has ever been before. But it looks like it has been very well taken care of. So what are the chances of fouling plugs, clogging the fuel filter, or otherwise damaging the car with this many miles assuming its never been seafoamed before and may have quite a bit of buildup in there?? Also, I have never seafoamed a car before. Yes I have seen the write up. Asking for opinions on doing this to a stock car without knowing any history of it. I have seen guys seafoam their cars at high mileage for the first time... but generally it had been their car for quite some time and they knew how it had been maintained.

 

Do it for fun. Smoke out the neighborhood.

 

87 k Really is'nt a big deal on a well treated LS 1 , just follow the instructions on the can. I would change my oil after the treatment.

 

At 87K you will probably get quite a smoke show if it has never been done. Go do it and be amazed at the difference!

 

I did it to mine when it hit 100,000 and man was it a smoke show on the beach. haha. Right during spring break. Man did I **** off a lot of people.

 

Haha, I might do it just cuz what black01_ws6 said sounds like a lot of fun. Maybe I'll do it at the park on base...

 

What kind of oil do you people run that makes your car need a sea-foam type cleaning at 80k?

That car hasn't even got its cherry popped yet.

 

I doubt it NEEDs it, but doesn't mean it isn't good for it. And I dunno how it was treated before I bought it, so why not clean it out as long as it won't hurt it?? Under normal use, no matter the oil used, a car with 80k+ miles is going to have some carbon buildup.
I just wanted to make sure I wasn't risking the car or more maintenance than its worth doing it. Seems so far most think it will be perfectly fine, so I may do it here in the next month or two. Just changed the oil... so really don't wanna waste the money doing another right now. Wait a few months and seafoam it before.

 

What do you mean by seafoaming it?

 

trade the seafoam for nitrous...it will be fatser...with a better smoke show

Edit: bout the nitrous, no. haha. Nitrous would be the absolute last thing I will do to the car. I'm just one of those guys that like to be able to say "all motor" when I do something instead of only being able to go fast as long as I have a bottle. Once its as fast as I can get it on motor alone, then maybe. Even then... probably go FI.

Thanks for the comments tho... for those of you who actually posted something worth while that is, instead of something like the N2O or "do it for fun" comments.

 

Oh wow. I think I need to do that. 103k miles and bet the previous owners hadn't done any cleaning to it.

 

I sea foamed my T/A at 80k and I had the fire department called on me because of the amount of smoke. I bought it used with 60k on the clock, and apparently it had some build-up LOL.

 

I used GM top end cleaner on my 2000 (through the brake booster hose...it's better than seafoam in my opinion) at 87K when I bought it. It seemed to help the car out a lot. I didn't bother pouring it into the fuel tank, I don't think thats as necessary at all. I did change the fuel filter and PCV the same day. The car I bought is very very clean/well maintained...but I think it was also pretty much barely ever above 10% throttle...it coughed out a few gigantic clouds of crap when I ran the stuff through it...and since then does run better. I think I'm going to run another can through it this weekend and then replace the plugs and maybe the O2 sensors.

 

Not to hijac the thread, but I'm gunna try to this here soon and was sure about somethign. The sticky doesn't seem to be clear about it. When you seafoam your oil does it need to be rigth after you changed the oil? Or do you just put it in whenever and change the oil within 250 miles?

 

I changed my oil 20 minutes after I did it.

 

is there a chance you can damage or foul things out when you seafoam?

 

i did mine at 84k and it made NO smoke. i guess mine was pretty clean. The fuel mileage went up and hesitation did go away though. i would recommend replacing your fuel filter after that tank of gas has run out. like mine, it was probably original. the fuel that came out was nasty brown.

 

I doubt you need to at 80k. I say pass on it.

 

pass, unless needed for a specific troubleshooting reason.
