Armed with 2 x 10m 1.25 ($8.00 at the local Toyota dealer) I crawled under the '97 LX450 to replace the gasket between the 2 cats.
Damn there was a drop of red fluid on the exhaust pipe and a small damp spot on the driveway...I figured great, now the transmission is shot!
The fluid turned out to be coolant....looked up and the culprit was the rear heater hose! Wonderful news!! I figure the lines have rusted through (Canadian winters and salt - lots of it!) and the day is pretty much shot.
When I reached up to see where the leak was coming from (core or line) I touched the little "T" clamp.. and it came away in my fingers...BOTH of them. The clamps had dissolved - literally ...was able to replace both in a few minutes with stainless Tridons (at least they claim to be stainless) and the leak appears to have stopped. Line replacements or a bypass are on the books now.
The Cat gasket didn't get done. First because the nuts and bolts are rusted beyond recognition and both bolts appear to be pointed (?) .. I will cut them off... BUT they definitely look a LOT smaller than 10mm....the rest of the exhaust bolts look 10m BUT the 2 holding the cats together are a lot smaller OR they have behaved in a very peculiar fashion and have lost 1/2 their diameter to heat and corrosion.....has anyone else seem this???
As Dan pointed out before ... 10m is what the FSM calls for BUT it sure is weird and looks closer to 6 or maybe 8... is the '97 LX450 different? are the holes bigger than they appear? Am I just too old for this?
thanks
