Re: How To: Sea Foam Automotive Treatment
Just did my first ever seafoam treatment on the 08 5.7l. I used this write up and some info from the comments. I got 2 bottles off amazon on sale for 6.99 each. Full bottle went into 1/2 tank of gas. 1/2 bottle each into oil and break booster line.
I got a rather large puff of smoke and was also able to confirm an exhaust leak that my dealer swears doesn't exist but I fricken always hear and it drives me nuts. As the engine began to smoke I saw a small puff come from under center of the truck. I suspect a gasket or something at one of the connections.
Anyway, it's only been in the truck for about 40 miles. I will be doing plugs, PVC, egr, map, oil change, and serpentine belt this weekend. I think I already see an improvement but nothing major at all. I'll report back after the full tune up.
