This isn't just another "How do I Seafoam" thread. I have done my homework on most of the subject but I still have some questions.. (1) When adding Seafoam to the crank case do I put it in when the motor is warm or cold? (2) how long do I leave it in for? Because I have heard some say no more then 5 minutes but then again I have heard someone else say you could leave it in for about 200 miles. (3) What your opinion on stalling the motor when sucking it in with the vac hose? A lot of people say to do this but cant the engine be damaged in doing so (hydro-lock)?
I added the SF to the oil after i did the whole SF run through with the brake booster. So that being said, anything is fine (temp wise).
I left my SF in there for about 1000 miles. if your motor is pretty gunked up, you should change it sooner u know.. also the next time you do your oil, change it at like 2000 miles.. this way its all getting out and efficiently.
I didnt let mine stall, it scared me. I kept my truck running until i was out of the SF into the booster. The idle would kick down really low, but i had my hand on the throttle....
After spending 20 bucks on this crap, i did everything i was supposed to, and didnt even get a smoke show
which then again is really good. and the previous owner of my motor rebuilt it. so explains alot huh> lol
