04 Lexus RX330 231,500 miles - valve cover pics

[newtoncd8]

Not sure where to post this topic, wasn't really a UOA -- mods feel free to move to another forum.


Below are valve cover pics from our 2004 Lexus RX330 with 231,500 miles; the vehicle was purchased new in November 2003.

Oil changes have usually been at around 5,000 miles with:
--Started with Mobil 1, then switched to Pennzoil Platinum early on and later Pennzoil Platinum High Mileage (usually 5W30)
---At some intervals, I would mix 60/40 of Pennzoil Platinum and Pennzoil Conventional
--I usually use Toyota OEM oil filters (an occasional Fram Ultra was used)
--4 oz of Tufoil with each oil change




For completeness, the last UOA was completed at around 221,000 miles and is located here:

Wow, great looking engine. Nice job on the regular oil changes.

 

[PimTac]

Very nice. For that mileage it’s super clean.

Your arm in that photo is dirtier than the engine

So do you think it was the Tufoil or the Pennzoil that kept it clean?

Super impressive

 

[walterjay]

Amazingly clean for that mileage. Congrats

WOW! Bee-yoo-tee-full!

Very nice job over all those years!

You should feel proud.

Very very impressive

Wow that motor is good for another 200,000 miles. I had an 03 Toyota Corolla several years ago that had 230,000 miles on it. It was used as a hospital delivery car for samples etc. and they would think nothing of running it about 400 miles in 1 day! Your engine is in great shape and you should be proud of your maintenance.

Thanks all, I was pretty pleased with how clean it was for the mileage.

Why did you remove the VCs? Leaking?

 

[slacktide_bitog]

That looks nice

Front was leaking pretty bad and back was more of a moderate seep/weep.

 

[demarpaint]

That looks fantastic.

Good ole Tufoil...

 

[Boss302fan]

Great job on keeping up with maintenance. I think with regular syn oil changes your engine would look the same. Not sure if Tufoil really improves on a good synthetic oil in a modern engine.

Those came lobes look hardly broken in.

Very nice !

What is Tufoil ?
