The valve timing phasers and timing chain tensioners on these 5.7’s is controlled with oil pressure. Same as all the VVT timing engines as far as I know. Ford ecoboost engines notoriously had those codes from chain stretching. It stretched so much the phaser didn’t have enough throw to compensate for it. Some of the 5.7 Tundras had problems with chain tensioners and you would get a rattle at startup especially if it sat for a while and the tensioner would bleed off. If it went away, it’s probably okay. You might have had a bit of sludge in a tensioner or phaser and it wigged out for a bit. If it happens again, try some seafoam and rev the piss out of it to get the oil pressure high and warm to flush out any little bits of sludge. Then change the oil again right away. I’d hate to see you buy a new crappy HD truck just because of a few problems with that Tundra. It’s still a really good truck and should be for a long while.
You should consider switching to 5w30 since your truck is a work horse with all that towing. Middle Eastern Land Cruisers use heavier oil than US market engines because MPG efficiency isn't of a concern out there.
Could be an ECM issue with detecting ethanol content in the fuel. It could be pushing more fuel in and flooding the engine if it thinks there's more ethanol than there is.
@@kedrevs4037 whats weird is when I get ethanol free at buccees (87ictane), I get worse gas mileage. Idk why except maybe its a computer calibration glitch with ethanol
Question I have a 2020 platinum...im thinking of changing my radio but I haven't because I heard you can't put the mic in the same spot as the stock mic...do you have your mic in the stock mic location
Maybe it's the sensor itself? Different vehicle, but my Dad's 06 Silverado HD had check engine light on and it kept saying there was a misfire. After replacing literally everything having to do with a misfire, engine light was still on. After even more research, found out the crank shaft position senser was slightly "off" and needed to be recalibrated. 5-10 minutes in the shop to get reprogrammed and no problems since. Maybe it's something to do with the sensor?
@kedrevs4037 I just got ny tundra 6 months ago and just found it takes ethanol. Haven't tried it yet. My truck is long cranking and smoking at startup sometimes. It has 130k on it
I have a 19’ Tundra .. NO issues, sounds to me like you’re having an issue with the ECU computer. I’ve had weird starting things happen before, i just disconnect the battery.. wait a few minutes, then try it again. Been fine ever since. I’d probably visit the dealer so they can check it out.
@@Swindy1794 many on tundra groups on Facebook have switched. In addition there is a post showing the manual from Mexico suggesting 5-30. That leads many to conclude the 0-20 is more for emissions rather than what is best for the truck. Plus it’s hot in Mexico. Also my wife’s Mazda 6 turbo requires 5-30. Same engine non turbo is 0-20. I would think for hot conditions and towing 5-30 is best. Mobil even makes a 0-30 I’ve considered
@@kedrevs4037 5W-20 agreed would be a better option than 30. Glad things were an easy fix so far. My 2021 TRD Pro has 42,500'ish so far and been awesome. I am definitely thinking about that Alphine head unit you have. Was it worth the price?

Certainly crossed my mind

Think that was the problem, fix I found is to switch to ethanol free when it happens

My mic is located just above the mirror very obscure.

All the electronics in modern vehicles, wouldn't surprise me
So, your fix was to change the oil? Is that what I am getting from this video?
I don't know, the issue stopped and hasn't returned for about 10k miles now.
Any more long crank issues since last video? Mine is doing the exact same thing now ...
It seems to happen with Winter gas, a fillup with ethanol free took care of it. No more issues

If it happens again, I may do that
💯💯👍🇦🇱
Timing issues don't resolve themselves with an oil change, not when you've been diligent with oil. This will come back eventually IMHO
Been about 4 months now, don’t know that was problem but time will tell and I will certainly document it
This would all happen at 2000 miles with new gen😂
😂
Have you considered 5-30. I’ve considered changing
Don’t do that!.. stay with 0-W20 full synthetic… change every 5K

Tundra owners manual says 5w20 is acceptable, But recommends switching back and forth bewtween Ow20 and 5w20 if you do that.
