Greetings, just wondering if anyone has ever had a negative experience with seafoam? I'm a bit nervous about putting this stuff trough my intake manifold. Could large deposits of carbon break loose and get stuck somewhere else or is this a pretty safe practice? I have a 92 accord with 115,000 miles.

 

Do a search to see other posts on Seafoam. Last time I used on my Acura Legend it sucked in too quickly and I had hydrolock. What does this mean? It's like the starter motor jamming and engine won't turn over. Solution? Take all spark plugs out. Cover holes with a towel (or you'll spray Seafoam everywhere) and give it a quick crank with the starter. That blows excess Seafoam in the cylinders out. Replace plugs, start up and drive about 3 miles at a steady 3000 RPM, or until the smoke screen disappears.

 

lots of people on here us/have used it without any issues unless you put in to much.... do a search as was suggested and I'm sure it will work out just fine

 

cool, thanks for the advice, just dont want any hydrolock issues or anything like that.

 

in a post just recently someone poured about 1/3 of the can down the brake booster line (at a fairly slow pace) with the engine running, then 1/2 in the fuel tank and the remaining portion into the crankcase and got some great results
