Fuel smell in oil
Hi!
Recently noticed fuel smell when I take off oil cap, is it normal on the M113K’s? ~2000km since last oil change but I can’t remember if the oil smelled fuel when I drained it. Don’t have a dipstick but the computer measures the same amount as I read when I did the oilchange
Been chasing a slight idle shake, might be related? Idles with a slight drop in RPM (drops maybe 50rpm and then back up) but drives fine or idles fine if I give a tiny amount of gas. Changed motor mounts 200km ago.

strongly advise a blackstone oil analysis
they will test exact amount of fuel in the oil, as well as many other traces that indicate anything (bearing wear, cam wear, piston rings, cylinder walls, etc)
all this for like 30 bucks. I just did it to test the health on my E55 with 204k miles that's blowing blue smoke and they stated they can see nothing in the oil indicating serious failure, such as zero wear from the piston rings. So this tells me it's valve stem seals
