    I was driving this morning, went over a hill and heard a pop, pulled over opened the hood and my oil filler cap blew off, it broke a little bit but it was able to go back on and tighten. the cap also had moisture on the inside of it, and lately so has the dipstick, it started rusting. so tomorrow i'm changing pcv valve and get a new cap and check any hoses. but I did add a oil catch can (I don't remember how many months ago) ive drained it a few times but could that possibly causing it not to breath correctly? or the reason its getting moisture? im probably gonna take that off and see what happens, if it continues then its probably something else.

    Well, I had the same issue of moisture in my '04...never had the cap blow off though. I now have a new engine and transmission, and do not have the moisture issue. So possibly it's an oem issue...I don't know.

    Catastrophic failure.

    My understanding this is a common problem on hemis...on short trips only. Run your truck long enough to get it up to temp, then see if condensation exists on the cap. Again, I've never blown a cap, or seen moisture on the stick, only on the cap. Stick to the oil change interval as well.

    Well changed the pcv valve, that was clogged a little bit, it's been 4 years since I last changed it. took the oil catch can off and had a bunch of gunk in it, gunk in the hoses, in the oil fill tube, some where the pcv goes, some in the intake tube and a little in the throttle body. Cleaned the intake tube and throttle with carb cleaner. Cleaned the pcv valve area and the oil tube. Added some marvel mystery oil, started the truck and it sounded better, took it to go get the new oil cap, opened it right up with no problems, can't even tell it was running at idle. Gonna change the oil tomorrow with marvel added to the fresh oil, run for 2 weeks or so and change it again.
