But that link doesn't work?

Jake

No worries chap's.

Mystery trim left off and all bolted back up.

No exploded diagram, local dealer has no clue and I can't access any manual for car.

Joy!

Just bringing this up.

Still none the wiser and it's bugging me

No one got access to a workshop manual that could have a quick look for me?

Ambermarine,

Do you have a link?

I tried searching but can only find threads where tinonline talks about his intention to change the belt?

I've got my belt off all fine, just need to decided on these seals!

No details of cam seals changes or any pictures that I can find!

Thanks

Sorry.

I meant to put TB (timing belt) not TV.

Its a 98 do a vvti engine.

cams out for seal changes as I understand, anyone got a manual write up for this procedure?

would be handy, they are only slightly weeping and if I can't find them at a sensible price I shall ignore it.

Thanks

Jake

I'm doing a TV change and all are slightly weeping.

Lexus wanted

£52.15 per cam seal and £46.63 for crank seal.

Also need rocker cover gaskets which were just under £17 a side from lexus uk

This is over £200 in seals alone,

anyone know a better supplier with a sensible price?

Thanks all

Maybe a dodgy switch stuck on?

Only a guess!

It's probably very rotten once you remove the shields and poke around.

The heat shields hold moisture against it which is where they seem to go.

New y section from lexus is £300ish plus VAT.

Weld a new section in is the way to go.

With regards to other areas the cat flanges are known to rot, these can be repaired but not quite so simple and easy.

The rest is stainless I believe.

There is no Check Engine icon on UK spec Mk IV LS400s. There is a "Check Eng" message in the text display below the speedo/rev counter, together with a warning tone and a small flashing warning light next to the text display, but no icon. I have confirmed this in my own Mk IV LS400 and in the handbook that came with it.

The "Check Eng" message does not show at start up - it only comes on if you have a problem. So if you have a UK Mk IV, you will not see any little yellow engine icon at any time, but if you see "Check Eng" in the display in writing then you have a prob.

If you can't see anything at all in the text display, then you need to get it repaired because important warning notices will not be seen, though presumably the warning tone will still sound and the little warning light will still flash.

Thankyou very much for clarifying.

Bluesman must either have an import or a mk3. Or just have confused himself again!

Thanks all

Yes its the handbook that came with my MK4 Lexus LS400 here in the UK. Thank you. Mike.

Maybe it changed amongst the mk4 cars.

very strange!

Can you try to reload the picture from a mk4 handbook?

And confirm it is actually a UK handbook.

I can't see anywhere a light will be on my dash, no outline of it or blown bulb upon removal and inspection

Bluesman,

You've also replied in this thread but with a different answer?

http://www.lexusownersclub.co.uk/forum/topic/84522-hi-all-new-ls400-owner-here/

I'm feeling confused.

does no one have a uk owners manual they could check?!

Where abouts is your light located on the dash?

Also is yours a UK car?

Further research leads me to the fact that a UK MK4 ls400 has no check engine or check vsc light.

The us cars do,

but the UK cars will display 'check vsc' or 'check engine' on the multi function display.

Thanks for help guys

..... pictures would be nice and some idea of the issues with the car that's costing £400 in bits please.

We have an unhealthy interest in all these things at LOC ................. thanks.

I'll start a new thread on it soon :)

No real issues other than blowing centre section of exhaust I plan to repair and a wheel bearing that I'm hoping will adjust up and be okay!

Already sorted washer level sensor and polished the faded headlights up :)

I have on order;

cambelt, tensioner, water pump, air filter, fuel filter, oil filter, cabin filter, fan belt, spark plugs, ATF oil, diff oil and engine oil. :)

Also plan to clean throttle body, any ideas where to source a gasket cheaper than lexus OEM?

And valve clearances will be checked, are the rocker cover seals usually okay to re use?

also anyone done a guide for checking these on a mk4?

Cheers guys! :D

hopefully going to end up well sorted and last a few years!

£400+ of service parts on order

Being worked over to perfection ☺

Normally the check engine light should come on and then go off so you know it is working.

Do you know this for sure on a mk4 ls400?

I can't even see where the check light is on the dash, I can see the outline to every other light?

Anyone got a video showing different light sequence to mine on start up?

I can only find American models and the dash layout isn't the same.

Thanks

Yeah its a mk4 98.

What do they mean by cowl side?

https://m.youtube.com/watch?v=Jwr6HFCQ2Yg

Would the above sequence be considered normal?

No missing lights?

Thanks

Excellent.

My paranoia is killing me!

I've just spent my friday evening working out how to remove the dash from a mk4, not thay obvious.

I got some pictures ill share later for anyone needing to remove the instruments!

Where is the light located?

I tried shining a torch to see it, but I can't even see the outline of it?

Thanks for the quick response.

As per title.

I have a mk4 I purchased last week,

should the CEL/MIL light be coming on when the key is turned to the on position?

I have never seen mine work and a bit worried now!!

Thanks

I can't work it out on any parts diagrams or anywhere obvious by looking!

Very annoying!!

This was behind the front left arch liner loose when I was accessing the washer fluid level sensor.

I can't see how it fixes or where it goes?

Has a clip and one hole in it. And foam all around it.

Any help please!?

Lexus sell them.

List at just under £75 plus VAT!

This is now sitting on my drive :)

Not quite as described, but I didn't quite pay the asking price so happy all round!

Just getting it perfected and sorting the niggles out!
