  1. - I just tried this suggestion on my 1992 LS400 and it didn't work. :( I took the failed EGR pipe to a hose shop and they did a fairly decent job of replacing the accordion section with braided stainless steel (w/ teflon lining) The fix only lasted a few days before the lining was breached and the exhaust gas began coming out through the braided section. So its a nice idea but it didn't work. I suspect the problem is either the exhaust gas temp is too high for the lining or the hose can't stretch lengthwise as much as the accordion can. I ended up having to take that fix out and put in a new OEM EGR pipe. (My mechanic was not too excited about doing it again but it took him less time the second time around) :whistles: The original pipe failure was two cracks in the accordion section. They are clearly fatigue cracks which means they will inevitably and eventually appear again on the new pipe. Witha all due respects to Lexus, the EGR pipe arrangement on this model is simple a badly engineered design.
