if you remove it you will have to disable it in the PCM. if you leave the valve and the solenoid connected then when the PCM tries to activate it it will set an insufficient EGR code or it may open the valve and now your dumping hot exhaust gas into the engine compartment. if you have an xcal2 or a chip i would just get it disabled and be done with it.

If you don't program it out with a tune, the car surges at part throttle and deceleration. The car is expecting that extra air to come from somewhere and when it doesn't the car bogs.

The one thing that I never tried was to hack the EGR pipe off past where the DPFE hoses hook up (closer to the header). That way you could put a little crankcase style air filter on the pipe. It would just suck in fresh air instead of exhaust.

You would also need to plug the hole in the cat or crush the EGR pipe closed.

I'm turning my EGR off with xcal2 on the svt because something is wrong, probably DPFE. EGR really doesn't matter, it's emissions junk for the most part.

And I guess I ain't cleaning my intake manifold cuz 8 gallons is a lot and I don't care that much. I'll run some BG 44k in the tank and do a fuel system tune up. Maybe it'll get some of the stuff out and it's free.

You may be able to get away with less but then your soak time will go up. I originally tried 2 gallons and it barely made a dent. The water was a little dirty after sitting overnight. With the 8 gallon 50/50 mix, after sitting overnight, the water was soo black that I couldn't see the intake manifold below a couple inches of water.

If you can find one, I'd use a tiny wire wheel on the dremel. Like this...

Even then I'd be careful that you don't suck aluminum dust into the cylinders.

If you do a search on Sears.com, look for a...

Craftsman Brass Brush Wheel
Sears item #00953132000 Mfr. model #53132
$2.99

The Superclean might turn the aluminum black, but yeah, that'd be one great way to get it squeaky clean. Just take out the buckets(lifters) so that the cleaner doesn't get trapped in there. Also, thoroughly rinse it off. Maybe even stick it in the oven at 250 degrees to boil any moisture off.


BTW, sorry for hiijacking your thread Rich. :eek:
