‘21 Valve cover gasket seeping at 30k?

Seems my 2021’s passenger side valve cover gasket is seeping at 30k miles. Will bring this up at next service appointment. Seems way premature to me. Is this common on these engines? Just did my 2004 Tacoma for the first time last year at 125k. Different engines of course.

 

Wonder if Toyota would consider that leak a warranty fix? Is it a failure? Well, if it leaks enough to have to add oil between changes, it sounds like a failure. Might be something they would not fix? Seems very premature IMO. I didn’t have any valve cover leakage on my 2016 Tacoma but I had front cover leakage. It was considered a failure by Toyota. Expensive repair as engine needed to be removed to reseal front timing chain cover.

 

That seems very premature to me, as well. I don't recall hearing about any others, so I don't think it is common.

 

Hard to tell if that's valve cover or cam tower leaking.

This leak is coming from cam tower. 245K miles though.

 

It all depends on the Dealer to be completely honest, Back in my wrench turning days with Infiniti, I was advised any leak was excessive and it would be covered under the manufactures powertrain warranty up until expiration.

I know people have a poor view of technicians but there are some very good technicians at dealers but they are far and few between. I can attest that I worked with some of the greatest techs in the region and made a very conformable living simply being honest. This is the exception not the rule.

At a minimum see if they could add some dye on your next visit and then verify on a return trip to definitely nail down the leak location.

Keep us updated on what you encounter.

 

Hey OP, what ever happened with this? I noticed a small amount of residue on the same area on my 22 with 13k miles. Completely unacceptable to me, as I plan to keep this long term, but the service manager mentioned that it needs to be a certain amount of leakage to be considered a failure. I am not sure how they determine that. I did not pursue it yet, and only asked that they note it on the ticket when I went in for a tire rotation last month. I will follow up and push for a repair, but as @Thatbassguy mentioned, this doesn't seem common and I could only really find your post on it.

 

I'll see if I can find my post but... our 21' had a timing cover leak at 40k, they covered it under warranty but it was 5k in work and took a week. Got a rental for the week on them as well. It was where the head timing cover and the block all meet. Ugh... not happy but it was free.

This. Once you cleaned off the oil residue and monitor you should be easily able to tell if it's cam tower or valve cover.

 

Don't worry, when the time comes, I will not let them get away with ignoring it. I just don't want to get too stressed about it until I have time to focus on the fight.

 

No this isn't the answer at all. I know my easy around the shop, but I will not be tightening it monitoring anything on my 50k truck with 13k miles. I will be having them replace the gasket so I didn't have an issue 10 years from now.

 

Don’t clean it off. Oil needs to form a drip for warranty repair. Otherwise they call it sweating which is not covered.
