Tan,
Thanks for the advise.
I'm only worried that there is not a lot of room to manuver.
As soon as the weather allows, I'll check it out.
i found my EGR pipe leak and after took it off, i see, there are 2 leaking. there is no room to do the path at all. it took me 10 hours and several trip to tools store to be finally got pipe off the car. 10 hours. Later i found there is no way to put new EGR pipe back to the car, there is no room to insert the top bent end wtih flage... so i capped the two ends and put exhaust pipe back... Since the ends were capped, the check-engie light is on. I called Lexus delar - just to put pipe back to car will cost me $950+tax. ohter car shop chars $600. I'm think to get new EGR pipe into two pieces at top of bent area (because of that bent so i can not have it inserted into the limited room) and use muffler patch material to make them become one piece to save 950$... i know i will then take me another several hours to put middle 12mm bolt to be tightened.
if anyone like to know the details for how to remove the pipe especially middle 12mm bolt, please email me at seattle_usa@hotmail.com. Iwill go step by step for how I did it...
Needless to say the formal way to remove/install egr pipe is to removed the transmission......... but with muffler patch, i'm willing to cut my new EGR pipe to ahve it installed instead of $950.... as I really don't wannt those dealer or shop to mess up the transmission.
