Could also be a vacuum leak. I had the same issue when I attempted to change my cam follower (I had 2 metal pipes so failed) - there's a vacuum pipe to the right of the HPFP but down a little which can easily break loose.

Check your PCV by having the engine running and taking the oil cap off to see if there's any noticable change. If it runs like a bag of crap but gets better when you put it back on it could be something else.

The other strange thing is that it only happens after a drive when the car is up to temp.

Does the car stay at temp?
