would you guys recommend a full seafoam treatment on my 02 blazer .... the spray for the intake and a shot in the oil..... already tried it in the fuel...

 

I would....you dont need the spray though.
stick a vac line in the bottle and let it suck up some till she stalls then leave the truck set for awhile and then fire it up...and watch the smoke fly.
you can check the seafoam website for more info

 

my buddy with his zr2 is doubtful of its effectiveness... how effective is it with the engine and its ability to restore lost power. did you do all three steps. gas, oil air?

 

Just did it to mine over the weekend...Runs so smooth now.

 

I did mine a couple years/engines ago lol. It ran smoother after a long haul afterwards.

A lot has changed since then with the engine mods etc, that was stock, dual exhaust (obviously) & a CAI.

 

sexy vid dude... im stoaked.. i want duals but what about the box on that side... is it safe

 

Box, what box? What do you mean?
My "duals" are a single in, dual out with the pre cat removed. Pre cat was removed after that vid was taken btw. It sounds 'healthier' now but not obnoxious. Surely isn't sounding like a mom n pops grocery go getter lol

 

the box in the fender... the fuel vapor canaster... and doesnt the cutting of the precats hurt the engine.... lemme know cause if its kosher im so ripping trhem out

 

i posted my exhaust in the exhaust thread... a recent thread

 

Ive heard that the way the vortec engines are designed putting the seafoam in through the vac line only covers the back two cylinders, and that why they make the intake spray kind. I think Swartlkk said something about that.
