Hello !

I have a 2000 4 door 2wd Sportage. A while back I noticed that it sounded like my motor had some sheet metal loose and rattled when I'd rev it up the rpms slowed back down and when I'd go thru the gears (like a harmonic vibration when it slowed back down).. Now I noticed that when I opened my oil filler cap on the valve cover that it had pressure behind it and think the PCV valve is stopped up. I can't seem to located it. Can anyone please tell me where to look. When the pressure is released it sounds different (if I loosen the filler cap while it is running). The pressure seems to be making the motor sound rattly. Like a sheet metal rattling sound. I am hoping this is what the problem is. It started a while back after changing my spark plugs and oil ...I don't know if it is related to something I did. The plug change went well and it ran way better. Does anyone have an idea of what it could be. Can the PCV valve and the crank case pressure cause it to sound funny? I am hoping I don't have a worse problem. I will not drive it until I figure it out. This motor has 80K miles and has not been any trouble at all til now. I love this little machine and it has been great so far. It has never used any oil at all and it should be nice and tight inside.

Can anyone tell me where the dang PCV valve is located ?

Any other comments about the what the rattling noise might be. There doesn't seem to be any sheet metal shrouds or anything that are loose and rattling. It seems internal. It does seem to change when the oil cap is loosened to let out the pressure. I hope I haven't somehow screwed up my motor. Any comments? I have confidence in you guys. I have never regretted buying this thing because there is such a 4WD following. I am a little worried about it tho. Please tell me what you think. Otherwise I may have to go get it diagnosed. I would rather do it myself. Any comments are appreciated. Thanks Guys !

Thanks.

look for the PCV on the side on the valve cover just passed the oil filler cap, when you do the timing belt do the tesioners and get a new tensioner spring, also buy a Kia dealer water pump only, you can get into big problems with after market ones not being the right one. the nosie you are getting unless I was standing there don't know off the top of my head.

Make shure it not the heating shields on the exaust pipes
they are nown to be a problem
Opening the oil cap changes the harmonic of the vibration so it MAY be the reason.

I had a similiar sound on my 01.. It was the catalytic converter rock sheild had been bent up close enough to just touch the cat and it made that noise, then the next year it was the exhaust manifold heat sheild. I'd start it up, and rev the motor while standing over it and listen for the source, whether it's on one side of the motor or the other or if it's underneath. The heat shields get brittle and break at the points where the 3 bolts bolts hold them on.

Any UPDATE Mr. Pat?????

With a flat head screwdriver you could just pop it in without taking anything apart....in like 10 seconds! <img src="/forums/images/graemlins/patriot.gif" alt="" />
