I installed a catback exhaust with UEL headers over this last weekend, and there seems to be an exhaust leak coming from somewhere in the headers. So i was going to seafoam the car to clean it out and find the leaks. The problem i am having is finding a Vacuum hose that feeds all 4 cylinders. From my understanding, the brake booster hose only feeds one cylinder, and the PCV valve only feeds two. Anyone have any idea what line i am supposed to be using?
dont use seafoam u wont find it. mix up a cub of ATF and a cup or water and sux that. all u need in a vac line that is after the throttle body and before the before the cylinder split in the manafold that sux air in. if uneed help im doing nothing after noonish 2marrow
i already have the seafoam, i just need to know where to put it, as far as i can see, there arent any vac lines that feed all 4 cylinders. Anyone know of one that does?
There is a hose and nipple on the top of the intake manifold. T into that for the best result Right in front of the Coil Pack and right behind the Idle Control Soleniod. Best bet is make another hose with a T and put it all together and let it suck from the can.
If your headers are new, just drive the car for a bit. The leak will turn sooty and make it pretty obvious where they're cracked/leaking. Skip the seafoam.
i was under the impression that this only fed 2 cylinders, and when i did remove it, the car died immediately, i am assuming that is why i need the T?
if u plug it with ur finger it should stay running if nto give it a little gas. i have always keep the car at 2000rpm when i but ATF or seafoam though my car
Another thing you could do is a top engine clean this will clean the injectors and valves and burn properly in the cyclinder head wile still giving you what your after with the seafoam. The one down side to it is it can clog your injectors so you have to remove the baskets napa should still sell them there like 2$ a pice last time I looked.
What are these baskets you speak of? I have some Subaru Top Engine cleaner, but i never figured out where to put it until this thread. I'd rather not clog my injectors though...
the baskets are on the tips of the injectors Ive never done it on a Subaru but I have on a couple of maximas and Toyota. I cant find the tool but its a canister that you pet about 8-10 oz of fuel with a table spoon of sea foam/ top engine cleaner, you screw the top down pull the fuse to fuel pump and pull a fuel line that feeds all the injectors, hook up air and pressurize to idel fuel pressure and start car till it dies then thro the baskets back on and your done. Its been a couple of years since I've done this so you might want to do a little more poking around the web but this was big with the GM techs. http://www.auctiva.com/hostedimages...ages=314772667,312709054&formats=0,0&format=0 http://napaautoparts.com/Search/Detail.aspx?R=CRB215001_0000999999 Heres what the baskets look like.
