yeah i dont think seafoam will do it maby reving her up to some high rpms but it prob wouldnt work

 

Yeah, unclogged probably wasn't the best choice of words. My cat was still clogged, but after all the hoopla with Pep Boys and their guessing of what was wrong, the bottle of seafoam got me to my destination safely.

 

i did seafoam on my 2.8 B5 earlier today and these are the results

nice vid....minus the plumber pants. haha

 

hahaha i know. too late

 

just curious but what exactly does seafoam do? ive heard bad things about it before... how does it work and can it hurt ur motor? i htink i have clogged cats thats why i ask.. i have 12v 2.8

 

Seafoam is like any engine cleaner. It eats up carbons and engine gunk. In your fuel system it's vaporized like any fuel additive and burned. It will clean your injectors. In your crankcase (vac lines) it eats up all that unburnt fuel/oil and helps your performance. In the oil it cleans out everything the oil touches.

When doing the gas, pour 3/4 to a full can into a full tank.
When doing the oil, add a 1/3 can to oil and drive 5-10 miles. Change oil immediately after. (Best to do as part of oil change obviously)
When doing the vac lines suck 1/3 to 1/4 can into the intake manifold via the vaccum ports. (Search the forums, lots of how-tos). Turn of motor for 15 min. Turn back on and rev until white smoke stops pouring out of exhaust. This is where a cat can get clogged. All that crap that is eaten by the Seafoam goes through the cat. The cat tries to do its job and stop that **** from entering the atmosphere and it can clog it. I had no problems though, and I don't know of anyone personally who has. Plus cat removal is a total pain in the ***.

(Also, just remembered you're 2.8, not 1.8T so your vac line seafoam entry point will be different than mine.)

 

so it actually clogs the cats? i hears it was supposed to clean them lol... and personally i dont think its smart to put in the crankcase (my personal opinion) but i will do vac line and gas tank... i just got to find out where the vac line is

 

Yeah, i dunno. I threw it in mine before an oil change. No problems. Why don't you think its a good idea?

Logically, it makes more sense that it'd clog cats right? I'm not sure that there's much out there to clear cats, but I could be wrong.

 

idk... just doesnt seem right to put anything other than oil in the block lol... just being paranoid i guess lol... but ive looked up the crap on seafoam and i cant find the diy.. anyone know where it is? and all the youtube videos are for 1.8 not 2.8
