[QUOTE="GirlDriver, post: 20957, member: 6725"] I got my vehicle used, but lucky for me I did some research and found out about the PCV orifice before any issue.... until my son sat idling in the car for hours [SIZE=3]in 100 degree heat and the a/c on. Lucky for me I'd put this oil cap on 2 weeks prior. It did its job - lol. Blew oil all over the place - no other damage. [SIZE=3]ACDelco GM Original Equipment FC219 Engine Oil Filler Cap[/SIZE] I'll tell ya what I did to clean out that PCV orifice that no one else has researched enough to figure out. You can "wash out" that area real good doing this. Because I'm convinced that sludge builds up on the back of the manifold where that PCV orifice is, just drilling a hole in the front of the manifold and poking something through there isn't going to clean it to where it would last any period of time. Take off the valve cover. The front of the valve cover is part of the PCV system. The PCV system makes a loop through there. There's nylon baffles in there. You'll see a breather hose on the left side that goes into the throttle body - so you get the idea of how it works. Anyway, the PCV orifice is smack dab in the middle of the intake manifold on the back side. Remove your valve cover and the center rectangle space (in the front, butts up to the back of the intake manifold where the PCV orifice lives) get a rag to cover the rectangled opening and spray some throttle body/intake cleaner in there with the hose, facing towards your intake manifold. Then with your blow gun chuck on your compressor, blow it out (don't forget the rag). It won't go in your engine, I promise!! I had to repeat 4 times before it was clean. LOTS of stuff came up after 105,000 miles. The car sat for a couple days, and no problems and it's been 4,200 miles. I'd let the car sit until you're sure any cleaner residue is dry.[/SIZE] If you live up north where it can get iced up, you drill a hole in the front of the manifold - real small - enough for a paper clip where you can poke through the orifice - there's a video about that somewhere on youtube. Then use a screw to seal up your hole and access later. [SIZE=3]But seriously being a direct injection engine, you need to do the CRC GDI cleaner process to ungunk your valve tops and that cleaner will keep the PCV free flowing once you've "washed out" the PCV orifice area good a proper with my technique.[/SIZE] [HEADING=2][SIZE=3]I can't do my own oil changes, but about this same time, I did 3 oil changes in around five weeks time and put in the Pennzoil Premium, natural gas, full synthetic oil. I didn't have any oil loss til around 1,000 miles and the oil started getting dirty. That stuff actually cleaned the varnish off my dipstick!![/SIZE][/HEADING] So I will come back here and tell you what good, if any, the LiquiMoly Motor Oil Saver did with the Pennzoil Premium high mileage, natural gas... oil this time. They didn't carry the high mileage version last time. Firestone carries this oil, which is where I got the idea to try it with a coupon. I think it's totally worth it. It's cleaning junk in the engine, so the oil gets dirty quicker, but I think eventually that will slow down. [/QUOTE]
