CATCH CAN vacum lines reversed! Did I F UP my engine?

Changing my oil. Went to clean out the catch can and it was bone dry.... I started looking at the lines and I think I had them reversed....

When I removed my oil fill cap it looked like a white cream.... SHIT, did I just F up my truck?

 

No. White thing is from cold weather

 

Maybe you blew a seal. Head gasket?

 

white colored oil usually means it has water contamination. I do not think a oil catch can could cause that. Also I don’t see how you could see that on the fill hole cap. Post a pic

 

Pull the dip stick

 

It’s highly unlikely you messed anything up.
Correct the lines and mark them (so the mistake isn’t made again)

The white milky liquid on the oil cap is normal.
Water vapor and oil. It’s common to see this in cold weather.
The problem can be mitigated by longer drive times with a warm engine.

 

Welcome to owning a Tacoma, you are fine.

So no part out?

 

Thank you all.

I cleaned the cap already.

Oil looked good. No noticable signs of discoloration other then oil color

 

I did..it looked normal

 

These "did I ruin my truck doing this completely benign thing" threads hurt my brain. The state of critical thinking skills is just sad.

 

Speaking of critical thinking, did you know you can identify the nature of a thread by the title and then not click it if you aren’t interested?

 

"Nah, it's just ice cream"

 

Awesome, thanks for the feedback. I am happy you are a master mechanic, engineer, etc...

 

Well said... My response to him I think is a good example of critical thinking

 

I’m calling dibs on your engine when you part it out.

 

Cream means water, has nothing to do with crankcase gases.

I find Toyota v6's don't produce much blowby, so I wouldn't expect much.

How is it routed?

 

Leave marine mammals out of this.

 

Done deal!
Where am I shipping it?
