Thread: seafoam in a higher mileage engine. Good or bad idea?

Our GP just rolled 233,xxx miles. I was thinking about doing a seafoam treatment since its over due for plugs and wires. If I decide to do it, I'll probably be using the vac line under the s/c snout instead of the brake booster line unless you guys think it will be ok. From my searching, some say the brake booster line is ok, while others say to use the vac line under the s/c snout.
But my main question is will the seafoam treatment through the vac line be a good idea for our car with so many miles? Is it going to hurt anything? I just dont want to damage anything. I already have about $700 worth of parts (junkyard parts/ used) to get and try to do myself. So I dont want to risk it if the treatment may do more harm than good. Which is why I decided to ask you guys first.

Thanks for you opinions and input.

Ask yourself, what are you trying to accomplish with it?

Cleaner pistons?
Cleaner intake tract?

Ehhhhh do your oil changes.. run enough fuel through it and ....drive on.

i used it with over 200,000 miles. she smoked like a pig.

i used the brake booster line. did a lim job after the fact and the rotors looked fine.

Scotty also makes my grandmother look like a race car driver

i drive faster then she does lol

she's dead, I sure hope you do.

I wasn't aware Scotty was known for driving slow

I'm with the other posters here, though. Just do your oil changes regularly, save the ten bucks.

I've put Sea Foam in my crank case tons of times.
