How do my air intakes look?

For a vehicle with 199,000 this is how each of the cylinder air intakes looks like. How are we doing?

 

Here's another one they all kind of look the same

 

Looks like you need a catch can

 

for that many miles, i say you are in pretty good shape.

 

???

 

It looks nice and very clean down by the intake valves. What fuel brand do you use, any injector cleaner? A catch can or improved crank case breather may(?) help eliminate the oil and crud that exists further up in the ports. But again, down where it counts looks good.

 

I just got the vehicle around 191k I mostly use Costco brand gas. I think I'm going to start using a techron additive.
What is a catch can? And where would it be installed at?

There’s a lot of hub bub about them, but they are designed to keep your intakes cleaner

 

Costco gas is a Top Tier gas that has additives in it for cleaning. Catch can is to trap oil vapor from going back into the engine, as I understand it.

 

Cool. Thanks all
