true story, before i fixed my egr tube i sealed up the noisy bit by taking a thick aluminum drink can, cutting it to the outline of the egr tube gasket, and then sandwiching the aluminum piece between the egr tube end and the exhaust manifold. it quieted things down nicely for a few years until i actually changed the egr tube, and it took only about 20 minutes.

Last year I had the pleasure (exagerrated) of replacing the starter on my 1996 LS400. It turned out that my EGR tube was damaged as well. I can tell you that I did not have to drop the tranny and/or the CAT. Obviously you will have to remove the front passenger tire. I had enough room to loosen the two bolts on the bottom of the EGR tube. I sprayed Liquid Wrench on the bolts and waited about 30 minutes before attempting it. I managed to reach the bolts by working my right hand from the front area of the EGR tube. I then used a deep well socket to loosen the bolts. Actually it was mor difficult to loosen the top bolts because the firewell is so close. I then fed the new tube from the top. You may have to wiggle it a bit but you will get it. I was amazed at how easy it was. On my first attempt, I attempted to loosen the CAT and it wasn't pretty. The bolts are not easy to break. Thank God I took a break. I could have created some unnecessary damage....

Hi,
I got a 95 LS400. The similar problem with lower EGR pipe. I heard some guys did it for 30 minutes. They must be extremely handy because I spent over 6 hours to take off the CAT. The bolts are like being welded to the nuts. I believe I have all the tools that I need: a few air chisels, wrenches, baby ratchets and air/eletric impact guns and more. The PB Blust doesn't work well, or no help at all. I have no choice but use a grinder with cutting wheels to cut the bolts. One of the 3 bolts of the CAT is hidden inside and the grinder cannot reach. I use one of the chisels of long shank to break the nut, so the stud is not broken but I need to tap the thread.
My problem now is, after the CAT off and the 2 nuts at the lower end, hard to reach the upper 2 bolts holding the pipe to the water bridge. They might get frozen too since using an impact wrench not helping. I know why some people have to drop the tranny. If tranny is gone, that shouldn't be a problem.
What about do it from under the hood? But removing the engine wire on the firewall should be a pain in the neck too.
Please help me out there. Btw, I replaced the starter a couple of years ago, which wasn't any fun at all; now the pipe. I'd never buy LS400 again: it's extremely hard to maintain. Really miss old American cars: you could sit inside the engine compartment doing whatever you wanted. Not any more because of the emission stuff.
Thanks in advance.
