Nasty intake manifold

[nocashrider]

OK so I cleaned the inside of my intake manifold as good as i could with some b-12 chemtool and a brass brush because it was gross in there with a bunch of oil sludge/gunk. So my question is what can be done to stop this from happening again and also what caused it to build up in the intake manifold anyways?

That is build up over the years of blowby be recirculated. There is nothing that can really be done to eliminate it, but you can do things to reduce it. Stuff like a oil catch can or doing a Seafoam type treatment every 10K miles or so.....

Or just dont drive the car .... Just kidding...

Yeah +1 to what Ben said

[nocashrider]

ok so if i went with the catch can route how would that be piped into the system or is there already a write up for it?

The breather hose that goes from the valve cover to the intake, it goes in line with the hose. You'll get two seperate hoses: one from the catch can to the intake and one from the catch can to the valve cover. Then you find a place to mount it if its a universal kit with the mounting parts supplied and viola. You'll have to watch the level and dump it every so often. There will be a sight on the catch can itself so its idiot proof. Unless you neglect to check it that is.

You just connect the hose from the Valve Cover to the catch can and from there back to the intake.

It is the hose on the pipe that is pressed into the driver side of the Valve Cover.

nice thanks guys ill order one of those up here pretty soon

Cant you just eliminate that hose all together? get a breather filter for the head and plug the end on the intake. Then you wouldnt recirculate that junk through the motor???

[fvillota]

wouldnt the filter get oil in it? or make a mess?

[Luni]

Actually, most of the crap you get in your intake manifold, like a gummy buildup is because of your EGR valve. Its recirculating exhaust gases back through the intake. Thats where most your garbage in there comes from.

[issymr2]

just get rid of your egr and get an oil catch can anyways

[fvillota]

yupp i got my oil catch and the egr block is coming soonnnnnnn

[Jon3sgte]

what exactly is this block and what does it do? is it just to block all that junk from getting into the motor?

[TomsMR2]

it took 19 years for that much stuff to build up in your manifold. its fine, dont worry about it.

hahaha yea thats very true.

when i say egr blcok i ment take everything that was to do with egr off.

I doubt anyone has ever cleaned the one on mine. Soooo, I want to do it soon. Are there any things in particular I should watch out for? Anything I would want to avoid messing with?

just take the whole manifold off. take the egr off and everything else on it. take the throttle body off. and use what ever you want. what i did was put some degreaser and let it soak then i washed it off and then i used about 4 cans of carb cleaner.

the inside is as shiny as the outside.

if ur gonna keep ur egr i recommend cleaning that out too and making sure the valve moves up and down loosely.

[David]

Thanks. I'm gonna do it tommorow.

[fvillota]

no prob man good luck.
oh and dont forget the starter injector thingie in the (middle front)

[TomsMR2]

id stuff 4 rags down the runners and have at it with a wire brush and some solvent. taking it off is a pain in the ass.
