Bkue is tailamp failure indicator. Top red is oil pressure. Bottom red is low oil level. Yellow is Check Engine Light. Purple is catalytic convertor overheat ( I think--I have never seen that before ). Green is low coolant level.

The shims typically don't wear. If there is excessive valve clearance, have your mechanic check the bottom side of the lifter bucket for wear where the valve tip contacts the bucket.

More than likely it is not a rod or engine damage, since the sound was not there when shut off, then appeared when restarted later. It is probably a piece of carbon on top of a piston. Sometimes the intake valves get VERY heavy deposits on the tulip portion of the valve ( between the stem and...

The pump pressure could be low, the rack control valve could be acting up, the solenoid on the rack may not be working, the pwr.str. ECU may not be working, or there could be a restriction in a hose or the cooler. The power steering on these cars is actually fairly complex. There is no way to...

That is 1 of the mounting holes for the steering damper ( kind of like a skinny shock absorber ).

More than likely the A/C compressor is locking up. WITH THE ENGINE OFF try to turn the front part of the clutch by hand. It should turn with slight resistance, if it takes a lot of effort or doesn't want to move you have a bad compressor.

Have you checked into the MEGASQUIRT EFI system. MSEFI.com I am currently assembling the MSIIV3.0 kit. It is very cost effective and very much hands on. You can purchase a kit that you assemble yourself or you can purchase an assembled unit. You can get an assembled unit and a basic cut and...

It is not possible to diagnose noises on a forum but,---The older V8 engines seem to get wear under the lifter buckets on the drivers side on the rear cylinders. If this seems to be where the noise is coming from then you will need to replace the bucket and adjust the valves. PS your drivers...

Usually when a car dies when letting off the gas when exiting the freeway, it has an EGR valve that is sticking.

Check for corrosion where the mast goes into the motor assembly. If that's OK Ohm check the coax from the radio to the antenna. If that is OK then you probably need an antenna assembly

Anything is possible as far as a short goes, but I have been working on Lexus for 16 1/2 years and I have NEVER had your problem that it wasn't the battery or alternator.

Either the car is not charging or the battery is so bad it will not accept any charging input---But more than likely it is not charging.

What kind of car and radio( Pioneer or Nakamichi)

Sounds like the trunk struts are weak. When you replace them, remove the little rubber block from on top of the hinge tube, this will allow the trunk lid to open farther making strut replacement MUCH easier.

I personally will never assemble heads without lapping the valves. Once when I was a young mechanic I assembled a brand new Mitsubishi head with brand new valves, then installed it and got it running only to find out one of the intake valves was very slightly bent. I have lapped every valve...
