Hi I've not had that pipe block up but have had a few blocked up egr coolers but it usually brings up p0400 code .gets full of soot. We used to send them to be cleaned out at local engineering shop who had a big hot degreasing machine that works under pressure

Hi did they put enough gas in the system?

I'm assuming that your ls has rear a/c

Hi you'll find the condenser in front of the radiator check for any oily stains on condenser and around pipe joints or damage to condenser fins etc. Have had a few compressors leak from front seal have you had it filled to check the operation of the a/c system? If it has got a leak you can fill it with nitrogen to find it not refrigerant

Hi did a few of these when I worked at lexus main dealer a few years ago. Underneath the car on the ns there is a plastic cover and the rear a/c pipes join there ( 2 unions one 19mm and another 24mm if if I remember correctly ) we used to cut the pipes further back towards the rear and remove the front pipes and take to a local a/c specialist who soldered them up then refit the pipes(leaving the rearmost pipes in place ) and regas the system. Only the front a/c works but it got cold enough. I still work on one of the ls430,s and a/c still works ok

Well I have had loads of these fall off mk 1 rx and never had a problem. It looks like the bracket has come off with it too so if you wanted to replace it you would req the centre section of the exhaust. Very expensive from lexus

Hi it looks like a vibration damper that is fitted to the exhaust I think it's on the centre section. Don't worry it shouldn't case any issues

Yes I think it was about £450ish a year strange that auto is cheaper!

Hi dexy sorry you are having a load of grief! That Is 250 sounds ok not much goes wrong with those is I manual or auto? I think auto drives a lot better and road tax is cheaper! I too have had lots of people complain about them too they just want to take your money and then you are on your own!

Hi dexy sounds like it may have damaged the head and block if that's the case will need new engine!

No problem glad to help

You will have to let us know how you get on

Yes you would have thought that the pre sales check would have picked up a problem as it has been faulty for a while staining on engine covers and pressuring the cooling system etc

Yes lexus told us it was carbon build up causing head gasket issues but whoever strips the engine needs to check the head surface and the block surface for damage where the gasket has blown. It may need a new cylinder head at least with the correct thickness gasket (usually the same as what came off) As I said earlier the heads cannot be skimmed we do try to in the earlier days but they didn't last too long before they went again

Hi all we used to fit lexus recon engines to 220d when I worked at lexus in Sheffield as you cannot skim the head and when gasket goes it damages the block too. Sorry I can't be more help

Fitted loads of towbar to 300 and 400h at main dealer with twin electrics or 13 pin socket was usually customer who specified which

That would be the first step and then try the to disarm the alarm I've done it before and it worked.

It looks like the hook for the accessory cargo net there should be one at each side and runs across where the boot opens

If remember correctly there are 3 chains 1 main one and 2 smaller ones on the cam each with their own tensioner. I will get in touch with one of techs at lexus main dealer I used to work at that I keep in touch with and run it past him but I've not come across any problems with chains on that engine but he may know different. I will let you know what he says

At least they found something but I don't understand this vvti belt thing as engine is chain driven only belt on it is the aux belt

It's a shame that you are not closer to me (I'm in Sheffield!!) would like to have look at

Cheers Simon I would be interested to know what's causing the noise because apart from the valve springs breaking (which I did have one once) not really come across any issues when I was at main dealers with that engine

Hi Simon has it had the valve spring recall done? Just wondered if it was a slight miss fire that was causing hybrid transmission to rattle I have had this before on Rx400h and Gs450h when they had slight miss fire sometimes with no engine light on either

Glad I could help☺

Hi Simon the noise was from the vvti controllers themselves not the chain. We just used to change the controllers. The noise was a loud rattle on initial cold start up for about 2 to 3 seconds does that sound the same as you have? As I said you can change them by taking out the camshafts without removing the timing chain front cover

No problem glad I could help
