I have a honda prelude w/ a 2.3 H23A1 block that has 160,000 miles and i began to look at sea foam to clean it. My friend used it on his trooper but it also has less miles on it and i was worried that using it might make my engine start smoking? I know it does for a little while after you use it but i mean like it would cause damage or pre-existing damage to show more. Anyways im good w/ cars but ive always been a little scared of addatives. Any help would be great. thanks

 

whats w/ everyone?? I was planning on doing this saturday and didnt want to mess anything up bc i do have a lot of miles on my engine. Any help would be great as long as its not guessing.

 

Seafoam is a great product. The thing will smoke like freight train for awhile, but will quit after the product is burned up. I have never had a problem with any excess smoking after using it on anything that i have owned. Good luck, Stubby
