    The design flaw is with Toyota and the FIPG application process. Not enough is applied by the assembly robot toward the rear of the engine, leading to the leak. I was just using Nissan as another example of a design flaw.

    Anyway, I don't know what percentage people consider "rare" or "uncommon", but let's just assume, for illustration, that 25% of all Tundras have this issue (I would consider 25% not to be rare). For any three Tundras, the chance that all three have the leak would be about 1.6%. For any two Tundras, like in my case, the chance that both have the leak would be 6.25%. All I'm trying to illustrate is that even with a 25% chance of leak, the odds that any number of trucks all have it are pretty small. As the actual rate of the issue goes down, the odds become significantly smaller.

    So, either I have very bad luck, or this issue is much more widespread than people think.

    I have a 13 with the 4.6l (155k) and it’s leaking on the drivers side. It’s not loosing a lot of oil so I’m just going to leave it for now and keep an eye on it and hope it doesn’t get worse.

    So for two oil changes in a row, at around half service interval (5000 miles), I have noticed that the oil level on the dipstick is down half way from full. So far I have not seen any leaks but to be honest I have not looked very hard. Could a truck with a little over 15,000 be burning oil? Never had this happen on my 2008.

    Anyway, I don't know what percentage people consider "rare" or "uncommon", but let's just assume, for illustration, that 25% of all Tundras have this issue (I would consider 25% not to be rare).

    If you look at the above post on the number of Tundra’s built for any given year as well as the number of Forum members posting an actual leak it seems that 25% seems high? I can’t find the number of forum members on Tundras.com as that would be a good indicator as well. When you do a Google search for the cam tower leaking it brings you here to this thread with very few others. Again perhaps it’s too much optimism or wishful thinking on my part but I still think it’s not as widespread. The fact Toyota has resigned themselves to fixing these knowing full well it’s a possible robotic issue is an indicator too. I don’t believe they are sitting in the Corporate office thinking roll the dice by fixing a few while under warranty hoping most don’t leak until warranty expires. But again, perhaps my optimism is creeping in again…..

    This may not be a permanent fix but applied a small amount of permatex ultra gray RTV sealant to the area of the torn FIPG and possible leak. Time will tell. Better than an engine tear down if it works for peace of mind.

    Yes, most vehicles will burn oil to some extent. You generally won't notice unless you're specifically looking for it. The allowable amount is sometimes outlined in the owners manual. The Tundra seems to not specify how much, but just that it will burn some.

    Has anyone here signed up for the class action investigation from the link on page 86? I’m considering signing it.

    Last time I did that it was concerning a banks bad practice of applying late fees incorrectly, I got a check for $0.86 and a team of lawyers got millions.

    If I was to sign up for this class action investigation, it wouldn’t be to get money. It would be to try and get Toyota to take care of this problem.

    Ship has sailed on the 5.7 cam shaft leak class action. That Toyota is smart.

    Took my 18’ back to the dealer in November of last year for the cam tower oil leak again. Driver’s side had clearly been leaking including a drop on the heat shield. This time, the dealer cleaned up the oil and added dye with instructions to come back in 500 – 1000 miles. Well, during COVID, this would take months due to little driving and short trips. It’s now 8 months later and I have over a few thousand miles travelled.

    I bought a UV light to see if I could confirm the leak before scheduling a follow-up appointment. I could find no evidence of dye when viewing the cam tower seal with a UV light. Is there any point in returning to the dealer based on my findings? I find it hard to believe it just stopped leaking.

    I have been paranoid of this common leak ever since I noticed this forum for cam tower leaks. I went to the dealer as well and they stated no leak; However, the driver side appears a little wet in the area of the FIPG. The passenger side is bone dry so obviously it is something. I just spray some dawn dishwashing soap on it and rinsed off the existing sign of any moister and will monitor it. It sucks for sure that we even have to worry about such a minuscule thing such as sealant that should hold up in this area. I personally would not prefer they open up my engine to do this procedure. It may cause more issues later. Fingers crossed.

    This includes Gen 1, people who don’t have a tundra, and people who sign up but are never seen again. It’s at the bottom of the main page. 60,785 as of now.

    Thank you and in an effort to be optimistic that’s a large number as compared to folks indicating they actually have a leak. I’ll continue to hope most all of us dodge a bullet.
