(the “didn’t fill” from above are all from AFTER the fix)

I did this a long time ago but I only posted it now because I wanted to make sure the issue is gone. And it is!

I finally found the culprit that’s been filling up my damn air filter, making the car run like shite and using oil like diddy.

It’s this at #4, the oil separator.

This car hasn’t had an oil change in a LONG time before I got it, gunked up the oil separator, clogged it, and the oil started going up instead of back down into the engine. Swapped, and you can see in the photo above how it was immediately fixed after. It’s actually pretty easy to remove, it just takes time to take off the airbox first, or at least that’s my mechanic told me. How he didn’t figure it out when I asked why I had oil in my airbox is beyond me, but whatever.

The whole job is almost as cheap as the oil I had to keep adding.

If you have this issue, you will see oil coming our from this tube that goes in the airbox at #36.

You didn’t ask for an auto troubleshooting tip? Well too bad!!!

Mine’s a Golf 4 1.4 petrol AXP by the way. Though, I think many cars have similar things.

If you know a community that could use this info lmk, I’m still trying to figure out lemmy.

      If the cylinders get scrubbed and pitted, diesel is under high pressure when it’s injected, and will get forced down into the sump. You can usually tell if there’s heavy blow-by from the crankcase breathers. Usually it’s something like an intake leak that lets dirt into the intake. I’ve also seen cylinder cooler jets fail and a cylinder will melt enough to create a hole. You’ll notice that as a cold cylinder because now it isn’t detonating.

      Diesels are born looking for new and expensive ways to die.

        Interesting, makes sense

        Maybe dad is right for fearing diesels lol

        I definitely would have messed up a diesel. I do quite a bit of city driving

          The ones that survive for a few years are pretty hard to kill. If you stick to a brand like Cummins or Cat, they’re bulletproof.

          Id never buy a diesel design with a single digit birthday.
