I found this thread. It confirms what you (sha4000) mentioned earlier that there is no need to remove the valve cover. Timing Belt, Water Pump Replaced...now Leaking Oil From Bottom Of Ocer

Thanks sha4000. I've observed some leaks on the camshaft pulley locations so that will be my other job while replacing the timing belt and WP.

Do you have to remove the valve cover to replace the camshaft seal?

Thank you for sharing. I hope that I won't have to do this.

It doesn't matter which one go to which location.

BTW, This is what I have.

I am thinking to upgrade my stereo with modern functions like Apple Play and Android. With Apple & Google Maps, no longer need NAV updates. Do you guys have any recommendation about Brands?

I haven't used it myself. But the size is adjustable between 2.5"-3.75" so it should be fine. I measured 2.5" on my 96.

I believe this was resolved in another the thread below: Stranger Things - 92 LS400 alternator saga continues - I think :o)

With the engine running, no lights (or load), the meter should read about above 14.2V. So,yours is normal. Turn on the lights and everything, it should drop a bit to maybe between 13.8 and 13.9V.. Turn off the lights and it should go up again. Your case is not normal if you ask me. Replacing the first one is normal, second strike is weird, the third one is even impossible (at least to me).. I've never been unlucky enough to replace more than two components. If it happens to me, I would say bye bye to Autozone and look where else. Besides the battery voltage, what else have you checked?

Thanks for making sure that I am not getting off the rail. Yes, after the second change, this time I replace the transmission filter. the car is quiet now. From looking at the filter, there are debris that were clogging it up. I think the transmission is reaching near to the end of its life. I don't remember reading anyone's post about transmission filter clogged with debris on this site but that's what happening to my car right now. After the filter has been changed, it runs smooth and quiet like there is nothing wrong with the transmission. Up to the point it started to clog up the filter, I was only using Toyota T-IV bought from local Toyota dealer. But now, I am switching to synthetic since type T-IV is not anything special anyway. Part 1 is done, Part 2: I will change the transmission filter again after 1000 miles and hope that the debris is no longer an issue. After that, I should be a happy driver until it happens again.

So, I change the fluid (drain and fill 2 qts) and it seems to help a bit. The noise occurs in the morning when I start up the engine and gone in maybe 5-10 minutes. There is nothing wrong with shifting or accelerating. Is the transmission pump failing and is there an instruction to replace one?

I got an alternator problem before (due to engine oil leaking out from the valve cover and camshaft). I replaced with a new alternator but covered the top of the alternator to protect it from happening again, so far so good.

There is a small circle shape rubber underneath the spare tire, you can pull it out to drain the water. A car hit lightly on the rear passenger side of my car to set the seal off causing water to get in. You may want to check the rear lights to see if any seal is knocked off.

I think the noise comes from transmission area. In the past, when it happened, the noise went away after I changed transmission fluid. I think this happens again. It just doesn't make sense that It happens again after only several thousand miles. I will wait until after the holiday to change the fluid and see how it goes. Thanks Trevor, I have not touched the EGR and MAF yet.

Thanks for getting back to me. I removed the drivebelt on Sunday hoping the sound came out from powersteering or alternator but the noise was unchanged. Does the MAF have anything to do with sound? The sound is generally at the end of the engine and near the firewall makes me think about the infamous broken EGR exhaust pipe but the sound is not like hissing air leak. I don't know what to do now so I leave the Lexus alone and drive my back up car.

The sound is like rattle noise. Yes, it is engine speed related as mentioned above.

Hello everyone, my car makes noise again. When it is cold in the morning, the car is idle with around 1400 rpm at first and the noise sounds like coming out from the back of the engine. When I drive it, the sound is noticeable at 1400 - 2200 rpm when I accelerate from stop or from low speed. It goes with engine rpm, not the car speed. What is the possible cause? Actually, the noise is also noticeable during the day but definitely much better than in the morning when it is cold. I am thinking about EGR pipe, MAF, or EGR temperature sensor but want to check if it makes sense.

I just want to follow up this thread. There was nothing wrong with the transmission. I spent time to change/flush the transmission fluid. It is now running so smooth and quiet.

The best way to find the part no. is to identify the small 5 digit number that is stamped on the connector Years ago, I bought two knock sensor wires with connectors from Sewell Lexus of Dallas & Fort Worth. It took some time for the part person but he finally found them for me. Their web site is https://www.sewell.com/showroom/lexus Good luck.

There is a buyer on Amazon bought this adapter (just follow the link below) for his 99 LS400. It should solve the problem for you. https://www.walmart.com/ip/BottlePro-2-Adjustable-Extendable-Car-Cup-Holder-Adapter-Hydro-Flasks-32oz-40oz-Nalgenes-32oz-40oz-Yeti-Ramblers-36oz-Klean-Kanteens-32oz-40oz-Large-/759427191

I think the battery should not have anything to do with the problem you are experiencing.
