TDi oil cap allowing dirt into the engine
Hi guys.
I don't know if anyone has observed this but i have noticed that the oil cap on my Polo 1.6 tdi seems to allow a little dirt into the engine overtime. I have bought a new one and changed it about 7 months ago since the old one even allowed water into the engine when it rained.
Any advice on how to sort out this issue.

Re: TDi oil cap allowing dirt into the engine
This cannot be good, seems like a design flaw. I don't know much about cars but having dirt in your engine will definitely stuff it up.

Re: TDi oil cap allowing dirt into the engine
Replace the rubber seal on the oil cap. Vw sells them separately, and wipe the area clean each time before opening the cap.
There's always positive pressure in the crankcase, I don't see how it would suck in dirt it's most likely falling in when u are opening the cap.
I had an issue on a 1.9tdi where the oil cap kept on leaking oil, a double seal fixed it. Might not work on your oil cap/Tappet cover tho
Does cap open and close loosely?

When a car tailgates me, i slow down - then floor it and give them a cloud of diesel smoke to choke on

No, it is not loose It is almost new. I bought it 7 months ago to stop rain water from getting into the engine.Ashveer03 wrote:Replace the rubber seal on the oil cap. Vw sells them separately, and wipe the area clean each time before opening the cap.

Another thing is if you look under the cap on the attached picture you will see dirt, how did that get in there?

Re: TDi oil cap allowing dirt into the engine
When I service my TDI, I pull the "funnel" from the valve cover and clean it (and that whole area).

Re: TDi oil cap allowing dirt into the engine
Buy a cover that goes over trailer electrical plugs. It fits almost perfectly over the cap. Stop sand from going into the funnel.
Drive the R21 with those uncovered sand trucks much?. there I days I want to kill them.
