So to start off I've got a 2002 SC430 and a few questions, I was looking under the rear end the other day and the exhaust tubes are smashed in on the top where they pass under the A-arms but both look like a match with the angle and amount of compression with the tube, is this done by lexus to prevent the A-arms from hitting the exhaust or is it from making a hard "landing" from a bump? Also I seafoamed my enigine through the PCV Intake hose(into the intake not the PCV) then I removed the Intake tube and looked through the main valve and there appears to be a pool of some fluid, I'd assume its oil as there is more fluid in there than the amount of seafoam I put in, is this part of the lubrication system? I didn't get a chance to check it afterwards but it was a thick fluid in there.

I think that the tubes are done that way at Lexus.
