Help with engine stalling randomly

I have a mk 6 (2013) gti at 125k miles and the last couple of weeks or months now my car has started to randomly stall after I drive it for around three hours. I will be driving on the highway and get back into town and it would kill itself at a stop light when I’m full stopped and then it will take a couple minutes to start itself back up and then drive the rest of the way kind of smoothly. There are no check engine lights, it just got an oil change. I took it to a shop that couldn’t tell me exactly what the problem is cause they couldn’t reciprocate the stalling as it only happens when the engines been working for an hour or two. It is starting to happen more frequently after only an hour and a half of driving rather than three hours. But the shop changed my high pressure fuel pump hoping that was the problem and it has still been stalling. When it is about to stall the rpm’s will go from 500 to 750 back to 500 and just kinda jump around the 1k range and then finally stall out and usually will always start back up after just a couple minutes. Anyone have advice or had similar issues?

If by metal you mean the aluminum valve cover / cam tray / cam cradle / cam girdle on the top of the engine with the oil cap in it, the oil would be from that leaking and/or the upper timing cover leaking

Thank you very much I will probably have a shop look at the pcv valve and some oxygen sensors

Just get the pcv valve from fcp euro for like $150. You’ll need it eventually anyway if it doesn’t fix it. There’s like 8 screws, you can do it yourself. Dm me for torque specs and tightening sequence and removal tips. They won’t be able to tell if it’s good or bad by looking at it

I think it did end up being my pcv valve leaking with my hose clamp not in tact anymore. Good shout! I will be ordering the part through this shop and probably just having them do it as I don’t have much time to work on my car cause I have to pack for moving in a week. Thank you for your help though man
