I'd burn that milky stuff out of there. Take it for a 30 mile or 40 mile drive, that'll clean the valve or cam covers up inside and they'll probably stay that way now that's it's warmer. Right after you dio that I'd change the oil, PCV valve and make sure you have a Motorcraft PVC valve in her. It SHOULD be a little easier on oil if your running the right stuff. According to Ford , there's nothing wrong with your motor. Using one court every 1000 miles is okay, according to them. I might try that first, see what happens. I doubt it stops the misfire, but burn as much crap as you can out of there, -then change the oil after you shut it off.
that's the weird thing, I've had that issue for about 8,000 miles now and the last two oil changes have been completely normal, only milky on the cap, the rest was a smooth brown. I'm definitely going to replace that valve and I'm going to do more research on the oil separator. Thanks for input and thanks to [MENTION=76842]Carcrazygts2[/MENTION]
The milky substance on the bottom of the cap is caused by short drives. It doesnt allow the engine to burn off the moisture
yeah but did I misunderstand him when he said burn off all of the milky stuff? I thought he was assuming all of my oil was milky, or was he saying since I have moisture in there (the cap) that I need to burn all that off by driving it? I may have just misunderstood his post, thanks
Yea that's the only way to get rid of it, a long drive. Takes a little while about 30 or 40 miles to burn most of it off. Some of it ends back crankcase thinning out the oil. That's why I suggested changing it right after the 30 or 40 mile drive. Those short trips are hell in the winter. It builds and fills the PCV system, - at times icing it up, IF you don't have a heated PCV valve.
If all you drive is short distances, that separator is great idea, - almost mandatory IMO.
My trucks down, it's been down for awile, couple years anyway. But I start it and run it on jackstands every 3 months to keep everything lubbed up, - run itr for about 20 miles and seems to work for me. Latley I've been screwing around with the engine and things. Allot of starts, idle then shutdown in a short period of time. for the last 3 moths. It's started to build under the cap, not much, but it doesn't take much. The more mile you got, the more blow by you get.
I think you have a better understanding now, Crazy's idea suggestion isn't the least bit crazy, it's spot on.
This stuff is almost non existent in the summer, but winter comes, you can get Miracle whipped!
User JMC from Canadia plumbed in a separator. I might have a pic, think it's...... Yea, here -
I'll try to nap some pictures of my setup. I have dual input single out put. I both valve covers in to oil seperator then it gets routed back to the PCV.
