^ This. I don't see anywhere they could put it without it ruining the back end. Genuinely the advice of RainX is good though - used that on my 2nd gen IS250. :D Brill.

End of thread

Could I be put down as maybe? :) Won't be camping, so thinking of attending just one of those two days if that's okay.

No surprise with the warranty, I expected as much! At the end of the day the dealer is responsible under the SOGA to either repair the car FOC or accept it back and refund you in full. If you do wish to continue with a repair according to my information P0138 is the bank 1 sensor 2 which is the post cat one on the passenger side Lexus part number 89465-50140. You could probably buy a Denso ( which are same as the Lexus/Toyota ones) for half the Lexus price. I would personally get another diagnosis from a trusted local independant garage as I am surprised that an O2 sensor is causing a rough idle from cold, O2 sensors don't begin operating correctly until the engine has warmed up and the post cat sensors only monitor the gases they don't control fuel ratios.

Who said they were dodgy? Are you speaking from experience? The one I bought was legit and half the price so why go to Lexus? I think there problem here is some people are to scared to touch their cars, like the type of person who drives to the dealer to put a new battery in there key!

Question from a grey haired old codger please.................what is WOT? Is that wot comes under the heading 'text speak'?

what i would do is put a radiator in it approx £140(but get it checked(pressure tested) not seen a is200 rad leak yet) put a new thermostat in it and try that first no point in jumpin in head first mate.if you still need to do the head gasket well you have some of the bits you were needing anyway so you've not lost anything. gasket kits with bolts are approx£100 timing belt kit approx £70 coolant approx £30 water pump approx £100 oil filter approx £8 (lexus one) oil approx £40 approx 6-7 hours labour if your taking it to a garage if you source all the parts it will be cheaper for you!!
