    It seems like it's happening more on the newer trucks which is surprising. I figured something like this would take 50-100k miles to show up. Very discouraging. It's not like the rear wheel sensor I had to replace for $260.00 ( did tick me off a bit tho). This is tearing the top half of the motor apart. I'm not sure I'd want to go through that regardless of who's paying for it.

    Hello all,
    First time posting but I have been monitoring this thread since Jan/19 as I noticed that my 2014 Tundra had been leaking. Both banks were repaired under the power train warranty on Jan. 11/2019 at 94495kms(58700miles). Over the last month or two, the engine seem nosier...nothing drastic though. I blamed it on the cold weather we had up here in Canada.Then I noticed a louder ticking present on cold start ups, similar to what you would hear when a lifter bleeds back. It only lasted a second or two but it was consistent. Never any drivabilty issues or warning lights present. I decided to pull the oil filter to see if everything looked ok but was disturbed with what I found. Metal filings throughout the filter. The truck has now 97699km(2000miles since repair) as of today. Its at the dealer as we speak. It is now out of power train warranty by 3 weeks. The dealer said he would try his best to work with Toyota on this. One of my concerns was that they never change the oil/filter after the repair..... isn't this part of the procedure or am I mistaken?? I have attached link to the photo oil filter photo

    I wonder it someone used a wire wheel to clean off the original sealant......Hmmmm?

    Ya when they finished mine and I brought it home, I opened the hood and I found a stainless iron wire sponge by my fuse box lol.
    It could be that too. But I also came back real early for an oil change, I believe it was 500km after the repair.

    I had the same findings with mine, took like 3 oil changes to remove the debris from the motor, I to feel they should give you an oil change as part of the procedure. I took pictures of my filter every time to document the findings in case I have any engine issues later on. But I definitely don't have a good feeling about it for the long haul.

    Happened with mine, I had pieces of wire wheel in my filter so who only knows what that did floating around the inside of my truck or if any is caught anywhere still in the motor.

    The visualization of a roach wedged in an oil filter just spontaneously manifested in my mind.....:rasta:

    I’ll know tomorrow or Friday what’s taking place hopefully. Can anyone confirm if the oil change is required as part of the cam tower seal repair?

    I believe all of the 5.7L engines are produced at Toyota's Huntsville, AL plant.

    Finally got the truck back. The mechanic said there were gaps in the gray sealant toward the back of the engine. He said it looked like a machine ran out of sealant during the process. He took his time to apply the black sealant appropriately and that’s why he tore it apart twice. He said as a fellow tundra owner he couldn’t let it leave the shop with being less than perfect. So I feel better. And hopefully I get some trouble free miles

    good news.

    and yes, I suggest getting an oil change at the 200 miles or less post surgery then another one after at 1,500 miles.
    IIRC I did 3 oil changes post surgery and with less than 3,000 miles: 200, 1500 and 3000. Maybe too much but oil is cheap.

    Changed my oil today since having both cam towers resealed. ~200 miles later and the oil filter looks pretty good. There was no sludge on the drain plug either.

    I saw this thread before I bought my Tundra in Feb. 2018. So far my Tundra has been great. At 10K miles, my engine has no sign of a leak.... Yet.

    After reading all the woes the F150s on the Ford forum were having, I decided to go with a Tundra. My old 99 F150 was running good, but it was costing me $$ with replacing the AC, leaky windshield, etc. I did not want to get stranded in the mountains here. There are areas of no cell coverage and tow trucks are not available in remote sites.

    Fortunately, a seeping or leaking cam tower shouldn't leave your Tundra stranded if that ever happens.

    I used this info to purchase a 2016 Tundra SR5 4WD.
    The dealer repaired both sides as part of the deal. Mine has 79k on the clock. Their price would have been $3200.
    I inspected three used Tundras and two had the cam tower leak. This is a very helpful forum.

    Yes
    Mine was there on the passenger side.
    It can occur on either. Have them do both sides. They use a black sealant rather than gray.
    Hold them accountable!

    So I got about 800mi on my 19' Tundra with the 5.7. I'm trying to keep up with this thread, but what should I be looking for to see if I have the problem?

    I looked in the wheel well from the front of the tire looking back into the engine bay, block. You'll see that woven mesh, think it's some heat shield. Should be the seam on the block right above that location.

    Shouldn't it really be a gasket and not just a sealant?

    Thanks I just went out for a quick peek and looks good so far from what I can see. Don't see any sealant squeezed out either like in the pic on the petition. Does this affect the Flex Fuel version of this engine as well?

    I've looked several times since I've had the truck, picked it up Labor day, 2018. Never saw a sign of it till this evening. Just rolled 19k on it. Can't answer about the Flex, don't think so but I'm sure someone will correct me.

    Watch the rounded area of the cover towards the fire wall. Look just above the front tires and shine a good light all along the sealant line. It is not difficult to see.

    Yes
    All versions can leak. Especially if your sealant is gray.

    Did a search on the leak. Found this forum. Signed up, add me to the list. 2013 Tundra Crew TSS, just over 76K miles. Had oil changed 3 weeks ago at dealership. Few days later, oil spots in the garage floor - nothing major. Took it back in following weekend. Advised it was dip stick o-ring. $150 later (was not happy, save for another thread) was also advised of the “minor-not to worry” cam leak. Service manager said if it gets worse, gonna be pricey. Could run up to $8K because they have to pull the engine or lift the cab off to repair. Talked to the technician, he said not to worry and if he does it, doesn’t have to pull the engine. Not sure what to do other than try not to worry about it.

    Bummer. My 2007 had it and I just kept an eye on the oil level. Maybe lost 1/2-1 qt over the oil change period. Noticed the leak at 100k miles when I did the 100k service on it. It had 137k miles on it and never had it fixed. Finally traded it in for a 2017 Tacoma had that for a year before going back to a 2018 Tundra. Cam tower started leaking before my first oil change. Toyota fixed both sides under warranty.
    There should be a TSB or recall on this for folks like you. It’s to bad all these 5.7L are going to be on the market to unsuspecting consumers.
