View Full Version : egr valve?

04-28-2006, 09:02 AM
ok so i unbolted the egr valve (i think) (two bolts-vertically) from the block and what do ya know... there are/were two holes in this part, one comes from the diaphram looking thing and the other comes from a "nipple" through the part into the other hole. I know, great description.... if i have called this part the proper part and so on the problem(i think) is the hole that comes from the nipple into the block was totally clogged with rust/dirt/i dunno.. at first i thought i had broken a bolt, but to my luck(i guess) it was only dirt/ crap... this egr valve is tied into another valve above it with a bigger hose. i have a picture, cant load it up here cause im retarded or something. if need be i will send pict via e-mail and you, the all knowing can help me, not knowing, fix this problem...
please advise ole wise ones.....:mad:

so, obviously with this part being all fouled up and doing nothing, should i worry about fixing/replacing it? and if i replace it how much do they run? and how do i get all that crap out of the engine/ hole area?????? thanks for posting that for me!!!!

If it was me I would replace it if possible.
Contact sarge at www.performancewebers.com (http://www.performancewebers.com/) he sells them for around $60.

use a pick, a piece of wire what ever it takes to clean it out.

so saturday i took the egr valve off again and cleaned up the diaphram and the entire part, got all the gunk and crap out of the port that was clogged, (the port that was clogged is now (or might have been before i cleaned it) a connicle shape. to clean out between the clogged port and the diaphram side i made a pick and slowly picked out crap. sprayed it heavily with carb cleaner and finally rubbed (with good old toothbrush) hand cleaner, on, in, and all around the part to clean it thuroughly. it looks new and i tested it with a can of compressed air(cleaned it out finally with that also). made a new gasket and put it back together. does it work??? have'nt got a clue.....

if im correct i think i also found the fule mixture screw. right next to the bolts (kinda) is a screw sunk into a countersunk hole. as i turned it clockwise the engine ran rougher, then i dialed in the idle control and it ran smoother. i understand that all of these together make a unit and if one is off then the rest are effected likewise. how do i tell if they are set correctly? i still think my timing is way off. gotta take care of that before anything(i think)... well, thanks for the info and help... this site and the people on it rock!rockonn

...i still think my timing is way off. gotta take care of that before anything(i think)... Yes sir, you're right!

The carbs can be complicated - computer controlled. I bought the Suzuki shop manual and that helped, but then I swapped motors so I don't have a lot of advice. Start with the timing and make sure the carb is clean. If you're still having problems I can go to the manual for you or I've seen guys talk about being able to down load the FSM (factory service manual) from somewhere...

good luck!

Thanks both o you'z for the help. ill be tinkering on the beast this weekend. its running allittle better now but i have this feeling like its being held back or something. i can go downhill and it will slow instead of rolling freely? im kind of leaning towards the wheel bearings are in need of some serious inspection or something to do with the e-brake... i know the e-brake isnt worth allot on my rig because it really doesnt hold well. so maybe im gonna repack my wheel bearings this weekend.... again thanks ya'll

Wheel bearings and brake drag are easy to check. Jack up the wheel and spin it by hand. It should spin relatively easy.

Let us know!
