EGR pipe...came lose from cooler real easy??

[Spanky Pete]

I just pulled the E/I manifolds and the EGR system. Going to get rid of some leaks.

Once I had the EGR stuff out the pipe simply fell out of the cooler housing. I had read this was notoriously difficult to disconnect, but mine just fell apart. There was some carbon on the down pipe, but only on the part that was within the cooler and nut. no streaking down the pipe. The nut is still on the housing side really well. I need to put in a vice if I am going to loosen it.

I am planning on replacing this stock pipe with the SOR pipe, but when I do, how do I ensure that I get that pipe connected to the cooler? Anyone else experience a loose EGR pipe like that?

I really appreciate the help.

There is supposed to be a sleeve that fits over the tube and under the nut. As the nut is tightened, the sleeve is compressed into the tube to make a tight seal. If the nut is not tightened enough than the sleeve won't seat onto the tube, and the tube will be able to slide out. The best thing would be to fit everything up on the truck, them mark the location of the tube in the cooler, remove the cooler and tube and tighten the nut on a work bench where you can get some easy leverage on it. I'm not sure how easy it will be to tighten the nut once everything is mounted on the truck.

Ha, I was just about to copy and paste and 2mbb beat me to it. I should have known not to take on the diagram guru.

I was going to point out that the sleeve is probably gone as well.

Hey Spanky Pete
Did you feel you had enough room to do the double gasket trick without removing the whole system per 2mbb in the other post?
Thanks

There is a ferule (sp?) that fits on the cooler end of the J-pipe. Above that rides the compression nut, just like a plumbing compression fitting. When the attachment is made at the cooler, the ferule is compressed by the compression nut, making for a secure, tight, presumably leak-free joint. At the upper end of the J-pipe there is gasket required for a tight fit. This second mating surface is notorious for developing warping over time. With regard to your choice of the SOR replacement J-pipe, I have read on this site instances of incompatibility with OEM ferule? nut compression fitting. I think this is why SOR recommends purchase of the two other parts with their J-pipe. P.S. If you've gone to the trouble of disassembling the manifolds, I'd recommend have them both machined as a single unit. Ouiet is nice.

It could be done. I don't think I could have done it. It seems to me that you would have to pull the EGR system (at least the valve and inlet) to be able to pull the I/E manifolds away from the head far enough to get a couple gaskets on those studs. I wasn't able to disconnect the nuts connecting the tubes to either side of the EGR valve. I just removed the whole EGR system and I/E manifolds as one heavy ass unit. I plan to tear down the EGR system and use plenty of anti-sieze compound when recconnecting, so that I have more options if I need to get at some of those components without pulling the whole thing in the future.

I was also thinking of cutting that inlet tube. Take maybe 2" off of it. This would make removing the EGR from intake easier/possible while on the rig.

Do think this would cause ill effects? It seems that the tube is as long as it is so that gasses are dumped into the intake downstream of the fuel/air mixture.

A common mod when de-smogging the 2F; one less impediment to air flow in the intake manifold while still maintaining PCV function.

Does cutting that inlet pipe affect emissions ? I mean Mr. Toyota made it extend into manifold for a reason - wish I knew what it was.

Is Texas a smog-nazi State ?

But it is common with a de-smog to cut that tube back.

The tube is positioned to be under the primary throttle bore. This is probably so there will be good mixing when the secondary is not open. Cutting the tube may reduce the amount of mixing which could lead to an uneven distribution to the cylinders.

Ahhh... In other words, probably increase emissions.

Thanks 2mbb !

Thank goodness, no. Plus, we still have 2nd Amendment rights and no state income tax...

You California guys crack me up - you sure worry about a lot of stuff!
