Hep - EGR

[Padgett]

Was just finishing up the LQ1 intake manifold gasket replacement and as I tried to reconnect the EGR, the flanged end of the tube snapped off. Is there a "quick and dirty" fix for this or do I need a new EGR tube ? I need to have the car drivable tomorrow. Block off the EGR maybe  or will that screw up the mixture ?

 

Please let someone have an answer.

I would block off temporarily until you can fix it right.

OEM part is 10127572. discontinued. Anyone know of a dorman or summat tube that has the same end and I can cut/n/splice ?

I never run EGR

Sorry nearing exhaustion, been working on this since 4 pm. How to you block it off and does it bother the computer or did you reprogram it to eliminate ?

 

Since I turned the "lean highway" setting back on will it lean out ? Am trying to get the tube off an old 3800 in the shop and splice the end from that but getting so tired am making mistakes (day started early, just working on this since 4 pm).

 

BTW does anything seal the coolant O ring under the throttle body or does it just naturally seal ? I do not see any bolt anywhere near unless I missed one.

I've never removed one from a 60*. technically all you have to do is block it off on both ends and if it's a 5 wire EGR leave it plugged in so it sees the pintle move.

Um if its already broken, just fold the pipe over with pliers and crimp it shut and cut a piece of metal to block of off on the intake under the EGR till you can source a new one. I forget how it attaches to the manifold.

Well just ordered a Dorman 598-209 which is later but seems to have the end I need. On the LQ1 you have a sandwich with the EGR connection plate in the middle (3800 is part of the manifold). Suppose all I need to block is the tube hole and if blocked that way should not get more than gasket hot, right ?

Oh well, had an old 3800 here and managed to get the EGR tube off and modified to fit the end over the LQ1 tube (interference fit). Seems to be working and not leaking so may work for a while. Along the way found I had to tap out the EGR mount holes to be able to draw down all they way. Wonder if that may have been part of the issue all along - didn't see any real leaks in the manifold gaskets. In any event the idle is now down to where it should be. Seems to be holding now, will see in morning if any seepage. While there I pulled the cover from the timing belt and looks fine.

The coolant o ring under the throtttle body (on the LIM) is pressure sealed. When you bolt up the plenum, it will squish it. The major thing is that you need to change it or it will leak. I made that mistake the first time I changed the LIM and I had a leak where that o ring was. In my defense, the LIMG kit I bought didn't bring that o ring. It took me 2 days to figure it out.

Temporary fixes tend to become permanent ones. If it works now, it shouldn't mess up unless it blows apart by pressure.

I'd be tempted to carefully put a hose clamp on the repair...

[Padgett]

I did. Not my first rodeo. Shouldn't be much pressure.

Have to the EGR on my 94 Cutlass vert this week. Those suckers ain't cheap either.
