Engine leans to one side? (Not truck leaning.)

Hi, I'm new here.
I was just changing my oil and I noticed that my engine is leaning to one side.
I pulled out a torpedo level and put in on the truck front and back bumpers and the valve cover.

The valve cover and the entire engine is leaning a full bubble+ to the passenger side.

I'm a bit concerned. I don't remember it doing this in the past, I always thought or noticed that it was level.

Does this sound like a broken engine mount or something serious?!

Thanks for any reply I get, and thanks for being out there to ask.

The rest of the truck has a typical, but not noticeable lean to the driver's side, as per the torpedo level.

 

Welcome to TW

Yup both the old and new four cyls lean toward the passenger side. The whole truck should lean a bit to the drivers side (gas tank, battery, and driver all make it lean) if it isn't brand new.

Here is a picture of my 3RZ-FE doing the 4cyl lean...


Here is a 2TR-FE doing the lean...

Whew! Thanks Speedytech7 for taking the time to find those images and post them!
It's odd, I know, but I really didn't remember that amount of lean in there....

Wow, thanks again!

 

No prob! Good looking out for your motor mounts, many people forget that their motor is suspended by rubber.

 

The engine leans to one side to allow proper oil flow throughout everything
Its easier to tilt the engine some than to redesign the whole oiling system.

 

Thanks guys! I too thought there was something wrong with my engine. Funny how I never noticed the tilt until a tree branch poked through my radiator. Whew!

 

Welcome to tacoma world. It's cool to see how people find this place. Sorry to hear about your radiator.

 

Very possibly true, seems to make sense.

I understand that the engine is tilted to reduce secondary engine vibrations transferring into the chassis/cabin. I.e. a perfectly vertical cylinder bank would transfer more vibrations into the chassis, but a slight tilt to one side would offset the vibrations just enough so the engine feels smoother from inside the truck. It's a NVH thing.
