Oil cap / dipstick blowing out?

Hey all! We have a ‘22 Tundra v6 turbo, our first “new” vehicle (bought it with 150 miles from Toyota dealer). We have not had any issues with the truck (it currently has 8k miles), except we noticed shortly after buying it the oil cap was off and sitting on top of the engine. I took it that the dealer (who had fixed the turbo on one side after 150 miles, the previous buyer traded it in upon the turbo failure, a common issue with these rigs it seems like) had simply forgot to put the oil cap back on. Today, noticed that the oil dipstick was out partially. My conclusion is that perhaps there is pressure inside the crankcase - which from what I understand, with so new an engine especially, there shouldn’t be. Anyone else have this same issue? Happy for any insights. The only thing I’ve done to this rig is change the oil after about 1k miles.

 

Sound like you could have compression getting by and going into crank case. I would call Toyota place.

 

I would think something else would let go before a dipstick getting pushed out, oil seals,vent tubs ect. I almost had to stand on the engine to get mine out yesterday! Maybe it never was put back in the whole way and you just noticed it?

 

Several of the new engines have been having major problems. Better do some homework, research, and get it to the shop for a look see. Hopefully it gets there before things go sideways.

 

I hope that is case. I him luck.

 

Welcome to Tundras
If you had that much crankcase pressure you would have many other lights, bells, and whistles going off
Hopefully you checked the oil, seated the dipstick properly and are enjoying your new truck

 

Could be the pcv isnt on correctly or broken.

 

Thanks for the responses. We're in rural Alaska, so simply taking the car into Toyota is not an option. It's an 8k barge ride to get to Anchorage We do have some local mechanics, but I'd rather figure out if I actually have a problem first. I've done almost all of my own automotive work out here so far, but was hoping there wasn't much to do with a new truck!

It makes sense to me given that there is a lot of variation on responses, and also that no check engine lights etc. have gone on, that maybe the best solution is to just check under the hood every other day and ensure nothing is amiss. FWIW I did open the oil cap while the engine was running - I read somewhere that there should be vacuum pressure and it is difficult to remove the cap while the engine is running. It was not difficult to remove the cap at all.

I wonder if there is something that is causing intermittent, but high, pressure? Is the PCV valve a possibility in that case?

Thanks all...

 

Ahh, a 22 in rural Alaska, yikes! I'd certainly be watching it closely. Might check the level just to confirm that it's correct. I'm almost thinking I'd consider letting it vent vs. blowing out elsewhere. Good luck!

 

Rural Alaska is the UN-candidate for a brand new platform vehicle. Would be rolling tried, true and easy to get parts if I was that remote.

 

I see a new engine in your future.

 

I’m betting PCV, it’s common and simple with turbo charged cars. Also… it’s probably your cheapest option. In a Subaru you can Pull it off and blow in it to validate if the check valve is working. I haven’t the slightest where it’s at on the new tundras.

 

Have you noticed the dip stick partially out more than once? I'm betting this is simply a coincidence and goes hand in hand with the guy that forgot to secure your oil cap. You'd likely be amazed at how often oil lube techs botch oil changes. Whatever the case, stick it back in and monitor it for a few days. If it doesn't come out, you're good to go. I highly doubt there is excessive crankcase pressure at hand. If there was, as others mentioned, you would have many more issues that are much more serious than a dip stick popping out. Welcome and enjoy your new truck!

 

Well in the infinite wisdom of Toyota and ford and gm and others they wind up with the dipstick tube too close to the center of the engine and this is the third truck I have had to put a long Phillips screwdriver in the dipstick hole and pull it closer to the driver side fender so I can reach it !! not everyone has a 6ft tall reach and after scuffing the stick where I can read it problem solved ! Hope this helps! smileytn1

 

The scuffing helped then? I need to do that. Really hard to gauge that dipstick.

 

This isn't as simple as someone forgetting to put dips tick in all the way. I've had my 2022 tundra right at 8, 000 miles blow the dip stick out and oil spewed out of it. It's happened 3 or 4 times already and the dealership is refusing to acknowledge the fact that something is wrong. Theybkeeo saying that this couldn't /didn't happen. However it's blatantly obvious that this is what's going on. The dips tick will be blown partially out and there will oil splatter on the underside of my hood directly above where the dip stick is and then it splatters from there all over my entire engine bay. The dealership just keeps pressure washing off my engine bay and putting a zip tie on the dip stick and give it back to me refusing to acknowledge what is going on.. They just say that there is. No way this could happen but if something does happen to your engine it's still under warranty and we will replace it for free.

Anyone else hanging this issue or does anyone have any idea what's going on? There's only 12,000 miles on my truck now and it's happens about 4 times already. This first time was right around 8,000 miles.

 

Something is obviously wrong. Try another dealer? What about if you open the oil cap when it's running?

Keep documenting it.

 

That sounds like blow-by from improperly clocked or gapped rings (on a turbo engine)

 

Maybe let everyone know if it does it again. For all you know it was left off and the dipstick wasn't pushed in . With the computers in these I highly doubt the oil pressure isn't monitored and warned if irregular

 

Blowing the dip stick out would be from crank case pressure not oil pressure but same thing I cant imagine there wouldn't be all the lights and warnings going on if cc pressure got that high

 

Definitely crank case pressure. The question is why. PCV valve not working? Massive blow by from improperly seated rings? Bad rings?

 

Make no sense other than a PCV problem. Any pressure in the case should be sucked into the intake and burned.

 

I'll keep yall posted on what happens. Thank you for the input. I just left my dealership again and they have the most incompetent mechanics at rick Hendrick Toyota in Charleston, sc. I just pulled out of the shop again where I bought my truck. This is the 4th time I have brought it here with oil all over my engine and they just keep saying nothing is wrong. I don't know what to do. I'm going to go to a different dealership and see if I can get a second opinion on this. Thanks again yall. I'll keep you posted.

 

Contact Toyota and open up a case. I'm sure they will tell you to try another Dealer first. That would get something started.

 

Try Fred Anderson on savannah hwy. Had my truck there for a couple scheduled services and they did good. Not sure about their mechanics/techs though. Hope you can get this resolved

 

We haven't figured out this problem yet. I would be willing to bet now that the dip stick wasn't pushed all the way down. Since we are not talking about engine failure.

 

Neither of the reporters in this thread with trouble have said whether the dipstick has unseated itself more than once due to pressure. Only mentioned the original instance where it may have been left loose. (and the OP with the fill cap off)

 

To my understanding with the DS not inserted completely wouldn't you just get oil vapor not actual oil being pushed out unless something is over filled or the pcv system is not working properly. Dealer keeps sending them down the road so there's a piece to the puzzle I believe we're missing.
