I have been reading different posts about egr valves. I have a Canadian made 92 metro 4 door hatch back base model 1.0 liter with automatic 3 speed. Which gen is it and what should I do for the egr vavle. Getting ready to put a new head on net week. Can use all info I can get. Not new to head work. Replaced both head gaskets on my 94 plymouth grand voyager. This though is putting on a new head so I know things will have to be transferd from old head to new. Also what should I do once in there? Thanks in advance to all helpfull responces and a big thanks to the creator of this forum!

GEN2 (89-94) and MK3 (92-94) You should remove the EGR valve and clean out the passages snaking through the intake manifold from both ports. One goes toward the front and into a straight passage through the head to the exhaust side, the other one goes toward the rear and empties out under the throttle body. You should also consider replacing the rings while you've got it apart. Lots of folks have replaced the head and found that the new, tighter top end just pulls oil past the old, worn rings. |

Don't have the time or money to replace rings right now. Going to roll the dice and see what happens. Hope they don't come up snake eyes.

Did you do a compression or leakdown test to test your rings? I replaced the rings on my '93 when I had the head rebuilt. Wasn't terribly difficult or expensive. Would be a shame to go through the time and effort to replace the head only to find that your rings are bad. As for the EGR, many folks clean the passage from the block to the TBI with a drill and steel wire. Attach the wire to the drill, stick wire in passage, turn on drill and go nuts. I tried that years ago. More recently, I cleaned mine while the intake was removed by soaking the intake in simple green for a few days. I removed the freeze plug in the back of the intake and was able to find a new plug at a local engine rebuilder. Cleaning the EGR itself was more difficult. I tried soaking the EGR in simple green but it didn't seem to want to come clean. So I drilled out the freeze plug in the bottom and sure enough it was still full of "crap." I then soaked in Simple Green and scraped it clean with a small screwdriver. The freeze plug in the bottom is 22mm, which is hard to find. I now have a whole box of them. Let me know if you need a couple and I'll mail them to you. New EGRs are more than $100; I got the box of freeze plugs online for $10. Brian |
