Ok, so, a friend and I replaced my PCV valve the other day hoping to fix an oil leak. It was definatly clogged but the oil leak hasn't stopped after replacing it. Not only that, but my car has a rough idle. It sorta scares me to drive it. I also took a look under the hood while the engine was on and it was vibrating more than it ever has. Now, my dad said that he thinks one possible reason for the rough idle is that the ECU is used to a clogged PCV. I read a forum saying that the PCV could be the problem. We have three cars in my family, one for my mom, one for dad, and one for me. Mom has work. Dad's at home so he can't drive...but my grandmother and uncle are coming in and they'll be using that car. I've got a very busy schedule so I have to rely on myself AND my car to get places. Dad wants to wait and fix it ourselves, but I don't have the time! I either need a quick, cheap fix or put it into the stealership. HELP!!!!

 

Well, I can tell you that the ECU doesn't "get used" to a plugged PCV system. It sounds as though you may have a vacuum leak. Make sure all your intake manifold bolts are good and tight, make sure you used a new gasket (most PCV kits come with one, but just checking) and make sure all the hoses are on good and tight- especially the one between the manifold and power steering pump. Also, before installing the PCV kit, did you make sure that both holes in the block were clean, as well? The bottom one, especially, is tough to clean up- you have to use a small, really stiff brush with plenty of solvent to get that one fully clean. The other important spot to clean is the part where the hose connects to the air intake hose right next to the turbo. I can't remember the name of that part offhand, but make sure it is good and clean, especially where the vacuum hose attaches to it- that's usually plugged. If the car is running worse than it was before, you left something loose or disconnected, or accidentally disconnected something and didn't catch it. Check all the vacuum lines along the back of the cylinder head, by the distributor- those tend to be cracked and brittle, and may break when disturbed. Good luck!

 

Oh- one other thing to check. Is the car misfiring? if so... do a compression check.

 

PM sent!

 

I went to AutoZone to see if I was getting a new code that may help with what to look for and apparently something is wrong wtih cylinder 1. Guy gave me a new spark plug and I'm working on that now.

 

Here's a loose vaccum line, but I don't know where it connects.

 

just behind your radiator there's a plastic cover that has a valve attached underneath it. pass it under the hose going to the intercooler, then plug & play.
