thanks will clean throttle body,,, also does anyone know if differential ep 80w/90 gl5 is good for power steering fluid on a lexus ls 400,,, thats what halfords recommended,,, thanks again

as an update, I have found that there is some p/steering fluid on the pump under the filler cap/tank, so it has a very small leak!, I cant look at it much due to restricted space I will have to dismantle some of the other parts to get access,,, the fluid level is ok though

thanks to everyone for their help,

yes that is very similar to what my car is doing,,,, I will give it a try in the next few days ( possibly next week when I have the money to buy the fluid), I will bleed the system and block up the valve/screw in the other posts,,, If i can I will include some photos to help anyone else who has this problem,,,, thanks

thanks to everyone for their help,,,, I have noticed that the steering fluid oil level is stable and not leaking,,,, its like a sprocket grinding sort of noise when the wheel is turned,,, maybe the bearings have gone in the pump??, the steering is in full working order,,, just very noisy

yeah, i will definately have a look at that when i remove the pump next week,,, thanks for the pointers,,,

thanks for the info I will have a look at that,,, do you know the approx area that the filter is at?, thanks again,,, Dan

thanks again

thanks fo your help, it is really appreciated and thanks for the tips,,, I wish u all the best with your car ,,, cheers, Dan

thanks for the offer but im a bit strapped for cash at the moment,,,, best of luck with your car, cheers Dan

Hi again, i think I need to replace the power steering unit on my 94 lexus as its very noisy, does anyone have any access to a sort of guide on its replacement??, any help will be greatly appreciated, thanks Dan ps, also my abs light sometimes comes on?? any ideas

thanks, will check all plugs and leads, the car is in rather good condition, it has been neglected even with a full service history! also I forgot to mention that sometimes the abs light comes on?/? the car has good brakes so I cant understand why,,, maybe its a sensor

thanks, will check all plugs and leads, the car is in rather good condition, it has been neglected even with a full service history!

thanks for your advice,,, anyway the power steering pump has no visable leaks and the fluid is at a constant level,,, I know it neds a lot of work but I have caught the lexus bug,,, I fell in love with the car as soon as I seen it, I know I shouldnt but its a very nice car and I value it highly to myself, I was going to have it painted white and maybe use it as a cheap wedding car. I think that the engine is flooding a lot when it was in the damp garage as it wouldnt start due to fuel all over the plugs, so hopefully it might be an injector problem? I was also thinking about getting an lpg convrsion. Im currently using a mercedes c class as my on the road car so I have lots of time to mess on with the lexus,, thanks for your quick reply, Dan

Hi, Im new to the lexus owners site, I have just got my new lexus ls400 today. I am fixing it up for a project and would like some advice from fello lexs owners, I swapped a rover coupe for it, an excellent deal if you ask me :winky: , anyway, I am very handy with spanners and I have noticed the following problems with the car,,,, , noisy power steering ( scraping grindy noise,,, fluid is clean red colour) I have also noticed that the car is running very rich on fuel,,, low on power, floods easily, lots of smoke, and engine oil smells like petrol . I have an general idea of what to do,,, but what do you think??, I think I need to service and flush the engine, replace the steering pump, clean the pipes and replace the troublesome valve/ switch that so many people have problems with. I would like to hear of your opinions and ideas, the only thing is that I have not heard of a lexus with the steering fluid leak that has oil that smells like petrol anyway, thanks for your help and advice on a very good site,,, dan
