_Bug_

So this next week I'm planing on doing quite a bit of work to my car. I'm changing the motor mounts, axles, oil, tranny fluid, and some other stuff. Anyways, I was reading some info on cleaning out the motor as well and came across some seafoam threads. I found out how to do it from this site http://www.diyimports.com/seafoamprint.html
I was wondering if I should do all three of the methods: brake booster, crank case and gas tank? Or would that be overkill and might risk hydrolocking my motor. I was also wondering is this stuff hazardous to my motors health? I want my car to run clean and strong, but I cant afford to put more money into it right now incase something does happen. From what I understand if I do it correctly and don't put too much in at once, I shoudn't have any problems. Any info would help, THANKS

how many miles on it?

i would do it : 2/3 bottle through the gas tank, and 1/3 bottle to brake booster (vaccum hose which goes into the throttle body).

Follow the directions on the can....1/3 booster, 1/3 tank, 1/3 oil cap

If you put it through the booster slowly, it will be fine...you will need to pull the throttle cable though
It can be bad if your engine has a **** load of miles and a **** load of crud in it..because the crud can act as seals - breaking them could cause leaking.

Use at your own risk

The motor (B16) has around 50k on it. When I do it through the gas tank and oil cap, do I leave the car running as well?

not to be smart, but do you add oil and gas to your car when its running?
no...shut it off for those

Sorry for the thread jack but if I were to pour it into the gas tank, would i need a fill up first like that heet stuff?

I did 1/3 of each. HELLA smoked bad when I poured it through the brake booster line and gave it a slight rev. It caused 2 of my spark plugs to go bad, so I just replaced them. Everythings fine now. Make sure to change your oil afterwards cause it thins it out.

If the motor's in good condition there won't be any problems. A friend of mine just bought a car with a H22 in it. He seafoamed it through the brake booster and then he went for a hard drive. He ended up throwing a road bearing.

The motor was in bad shape when he bought it and the seafoam loosened up carbon, which clogged up his oil pump/feed (something oil related) and he ended up throwing a rod bearing.

See reading about stuff like that makes me not want to do it. I'm pretty confindent that my motor is still in good conditon, bet then again I bought the car with the swap in it and have the recipt for the swap which is less than a year old. I'll have to think about it.

lol sea foams not the reason for throwing a rod. if you dont over kill nothing bad will happen. just remember if you have a lot of carbon build up in your motor it might smoke and burn oil for a while untill it builds up again. i poured almost a full bottle in my 84 toyota supra it already burned oil but i think it made it worse. becasue now 6 months later it doesnt even burn a quart between oil changes. use to burn 5 quarts between oil changes. but remember sea foam is suppose to be good
