Default intake blockage/ buildup of stuff???

ok, i have yet another question.. ive heard mopars are notorious for the intake manifolds to build up crap to restrict air/fuel flow into the engine, is this true? how much can it affect the engines overall performance?? and is it easty to dislodge or clean out??

Never heard of it. But maybe an old iron intake manifold could develop some rust on the inside, if there was water in the gas?

What they are famous for is a build up of carbon in the exhaust crossover.

In many cases causing complete blockage.
We canucks notice it more, because it makes the warmup slower, and becomes a pita in the winter.

It won't affect all out power.
In fact many people block that passage off intentionally so the intake charge is cooler/more dense.

Hoep this helps

I think you're talking about the common plenum gasket failures on the '90's Magnum V8's. I know with those it would suck oil into the intake and create a bunch of carbon and sludge deposits and junk stuff up. I don't think old Mopars do that though. The only reason you might get buildup in the intake would be from some HARD CORE backfiring.

edit: Just read Dave's post, that may be what you're thinking of too...

Only blockage I've seen or heard of is the exhaust x-over as mentioned. That may also affect the EGR passage. None of it will affect the intake passages, only rust and dirt would maybe settle in there a bit. A hot tank will cure all of that.

I block all my crossovers, stupid thing, some intakes dont even have it.
PCV valves can suck some crap into the intake, but entirely block it, no, must be the crossover. It will make it a bit cold blooded, but I dont notice, as I dont have chokes on anything with a carb. My Valiant has a air gap intake, and it will ice over bad in the winter, kind of hard to tune that thing when it does that. I just let er idle a bit and the ice goes away.
