PostSubject: Seafoam and TBI's   Sun Oct 14, 2012 10:47 am

I was cleaning out the garage this weekend and found a can of Seafoam I must have bought at some point to throw in the wagon. I figure it can't hurt to finally do it. I know the basic principles of how much and where, but need/want to know what vacuum line(s) to pour it in under the hood.

TIA!

I had a 91 TBI caprice. I started the engine with the air box off. I put about half a can in a spray bottle, and sprayed it down the throttle body till it was gone, while working the throttle to keep it running. After I put the remainder in the tank. It really cleaned the car up, and I saw an increase in miles between tank fulls.


It will smoke and cough like crazy while you are doing it, just keep the rpms up enough to keep it running.

On my OCC I slowely poured about 2/3 of the can into the throttle body while holding the throttle open a bit to keep it running. The I dumped the last 1/3 in until the engine stalled. Let it sit for 15 min, fight with it to start again and drive the hell out of it until the smoke show ends Very Happy

Thank you gentlemen. I think I'll do it this week when my neighbors have an open house. Twisted Evil

I did what Dave did. There were no mosquitoes in Malden for a while afterward.

I just found a can this week at my house, I may dump it in the Caprice since I've never done it on that car before... Twisted Evil
