Camshaft Oil Seal Mystery

Recommended Posts

Hello folks.

I just purchased a 1999 LS400 with 300.000 km on the clock. Runs super smooth but the timing belt and valves were not done in the last 150.000 km's so I decided to do it myself. I have all the tools so I ordered a complete set. Timing belt, water pump, Tensioner, tensioner and idler bearings and camshaft seals.

Now the problem was that I got the wrong camshaft seals. The seals that were provided have a smaller inner diameter. They are probably suitable for the non VVTi 1uz-fe. In my case the cam seal seals around the outer side of the VVTi unit. The inner diameter is 71mm. Outer diameter is 85mm Thickness is 10mm

Now I went back on the internet looking for the right camshaft oil seal. The original seal had the label:

NOK BH5855E

Well.. Now I type this number in google and I find no information or offers. Then I looked in the rockauto database and look for the correct oil seal. Well.. This is where the confusion started..

I go to my 1999-ls400-4.0l-engine-camshaft seal. Here I find many seals that look like they are correct. But also they all have different sizes..

List of 1999 ls400 camshaft seals according to rockauto:

DNJ CS970

Timken 223802

SKF14713

National 710554

National 710861

Fel-ProTCS46050

Beck/Arnley 0524008

Now the weird thing is that when the sizes are given all these seals are only 50mm outer diameter according to the database information. Some of them have no size information.

When looking simply in the google and ebay ads that pop up when typing lexus ls400 1999 camshaft oil seal the most common article number I find is: 9031171002. But when I check the interchange information this seal is only 50mm in diameter!!

It should be 85mm outer 71mm inner and 10mm thickness.(these are the sizes of the original seal with number NOK BH5855E that I have measured)

Well. After checking all the yoyopart and kakapart database on interchangeable oil seals the only seals that I find all have 50mm outer 38 inner diameter according to these website. Also i find the SKF 14707 and SKF 14713 As a interchangeable part.. Also this part has a 50mm outer diameter according to that website.. So its not the part I need.

I now spend the last 2 days looking at the part numbers and checking the sizes of them and the proper seal can not be found for sale as far as I can see. So or I have become crazy. Or all the sizes given with the seal numbers are wrong.. Wich one is true?

Well. Since I can nowhere find the real proper partnumber of the correct oil seal I have no idea what I should order.. Anyone have the correct number or lexus part no for the oil seal that goes around the VVTi unit in the 1uz-fe VVTi engine?? And if possible alternative brands and part numbers that will fit. If there is a SKF number for this seal I would be very happy as well.

I hope anyone knows exactly what I need and found a way through all the seal numbers..

I hope someone can help!

Welcome!

The Toyota DIY site shows part# 90311-71001 for the cam seal. A quick search reveals a few sources but as to exact size, I do not know.

Take a look at this and see if it might be a possibility. You do know that you have to remove the cams to get to the seal?

You are going to find out that some parts books other than the dealer ones are goofed up on some parts for these cars.

The cost dealer seals will not break the bank. That is where I would go if your local auto parts store can't find some. Forget all the online stuff when you are stuck. Rock auto is good but if there was a goof up with not so costly parts like a seal, then go in person some place and show them in person what the problem is. So much less hassle than dealing with something you can't see online.

Yes I have the complete cams already removed. Reason is that I had to set the valves. It was really really time.. I only had 0.05mm play at some of my exhaust ports. I hope there is no damage already done. It ran sweet and strong so I hope i am just in time. I also have to screw of the VVTI unit to be able to change the seal I see. It will not get on from the back. Anyways. The part number you gave me is a number I have also found. Just stupid thing is I can nowhere find the sizes that this seal should have.. And according to the kakapart list it is interchangeable with seals that are only 50mm in diameter.. Maybe that Kakaparts website is totally *BLEEP*ed up with its interchangeable list... Maybe that is what causes my doubts..

Just still no alternative part numbers for a real interchangable part from different brands. I would like to have those if anyone has them. If they exist at all ;-)

Cheers.

Here is a pic with part number of the seal that you need. I also posted a pic of the first seal they sent me which was way too small next to the correct seal so I understand your confusion. I had to go to the dealer and pay $30 a seal to get the job done. It seems like the beck/arnley one on rock auto is a match

Wow! a new number again! I am slowly getting crazy.. So now I need 90311-71001 or 90311-71002 or now a new number 90311-A0004. Whahahahaha.. Wich one is best?? Are they all the same?? Is this seal the same for the LS400 VVTi and LS430?? Seems like no one has the seal here in the netherlands except for the dealer. And the dealer dares to ask 51 euro for one seal!!!! I would say let them die.... Thats why I tend to find out the right part no so I can order online. But still I get more and more numbers..

The 90311-A0004 that you now give me. Was this one fitted to a LS400 with VVTi? or a later model?

The world of Toyota and Lexus parts is getting completely rediculous and Crazy. I now got the number 90311-95012 ;-) We keep saving numbers. But I really think this dealer was drunk..

Well I'm going with the ones I posted since I changed them myself back in May. I got them from the lexus dealer. That 90311-71001 is cross referenced with 90311-A0004 on the lexus site.

http://www.lexussouthatlantaparts.com/products/LEXUS/1999/LS4004000CC-32-VALVE-DOHC-EFI--AUTOMATIC-5-SPEEDSEDAN/SEAL--OIL-FOR-CAMSHAFT-SETTING-SEAL--TYPE-T-OIL-L/9928096/90311A0004.html

The 90311-95012 is a part number for a rear crankshaft seal so I would ignore it.

The 90311-71002 seal is for later year vehicles. Mainly the 4.3L and 4.7L engines.

Ok.. It sounds logically. Although the dealer here told me the 71002 is the same as the 71001. He told me they just updated the numbers. . So that would mean they are all correct exept the 95012. Wich I already knew can never be the correct one.. Well. If you are sure it works on your vehicle.. Its unfortunate the A0004 is nowhere for sale here in the netherlands. Ill have to order it online then and wait a !Removed! 10 days or so..

Well.. somehow I will need to take the train then ;-)

Wow! I found a new part number that absolutely matches the sizes of my old seal. Its AJUSA 15063500

its the exact match..

85X71X10.. aND NOT 85X71,5X10 LIKE THE 90311-71001

I already found it weird that the 71001 is 71.5mm according to this link: http://www.infodozer.ru/catalogs/musashi/search.php?model=SOARER&maker=TOYOTA

And my VVTi unit has 71mm diameter. I wonder if the 0.5 difference will make it work better or worse.. But the 71,0 should at least be the correct one! So Ill try to find the AJUSA 15063500 ;-)

OK.. just bought the cam seals at my local lexus dealer. Had to pay 102 euro ex VAT. Means 122 euro wich is around 154 dollar for 2 oil seals. This is how we get beeped in our asses in the Netherlands by our dealerships.. Its true and unfortunate. In the US tehere are plenty of parts available... Here we can get bankrubt on one screw

Gosh a friend in US could have sent you a gift, that's a horrible high price. I wonder what the sewell price would be here?

Well. I did like to order in the us for around 15 dollar each but ill have to wait an other 10 days untill I get it here. I have time this week to finish my car and no time after the weekends. I surely wished I could buy here locally from different brand and dealership for a normal price but the seal really is not available outside the dealership. They have the monopoly so it seems so thats why they just do.. The Netherlands is not like the US. We are not protected from monopoly positions. Unfortunately.. Now you understand why I was desperately trying to find the alternative part numbers for the right seal. And even though I found quite a lot of them. They were all not available at this moment..... This is europe.. Down the drain I would say..

I never saw anything saying where you were at. I thought it was US. Any future LS projects try to plan ahead and order from US.

Yes I did plan ahead. Unfortunately the ebay shop that I ordered from supplied the wrong oil seal. Its basicly their fault that I am now 10 days behind and in the end pay double the price of the whole set cause of oure rediculous dealerships. I know Rockauto has it but its also comming from the US... Would take around 10 days.. Anyway.. Next time I will only start after double checking what I have got... I guess thats the only way...

Amazon also has compatible seals. When I got mine I did not know what was compatible so I did not want to take a chance but after I got them from the dealer I knew I could of saved some money and went with the amazon seals.

I did check Amazon too. Unfortunately all suppliers on amazon were also positioned in the US. So no option if you need them quickly. Anyways. Thanx everyone for thinking along. Unfortulately none of the part numbers are for sale in the netherlands for a normal Price.

Cheers!

Ok make sure you seat the seals correctly and pay attention to the front bearing caps to make sure they are not leaking. Those are supposed to be cleaned and new FIPG is supposed to be applied.
