so there is a wire coming from the intake manifold into the top of the block head, i found a dark spot on the engine around the entrance, should i be concerned.

 

Try to post a picture.. I don't fully understand what you're asking.

 

ill try and get one, sorry not a wire, a small hose going into the block head that has a plastic piece connected directly, it comes from the intake manifold, soon as my camera is charged and ready to go ill go take some pics

 

I'm having a brain fart right now, as I cannot find the word for what it is. When you can post a picture.

 

older pic but at 12 o clock on the head right in the center there is a gray piece coming from the head and directly into the intake manifold, around that gray input there seems to be an oil stain of some sort around the lip of the entrance

sorry for the old pic and no circles in class right now worked late last night haha, but yeah thats it

god this engine bay is dirty compared to now lol

 

That's the PCV valve.

 

and there shouldnt be a dark oily looking spot right? if so should i replace it, or should it not be of any concern

 

it looks like it should be replaced every 50k miles which i am at 97k and from what i have read on pcv valves is that they tend to get clogged. common sense would tell me a clogged valve will spit up a little bit resulting in that oil on my block head. thanks psl for the part name, this could also be why my mileage is suckin lately, i guess i get to have some fun tomorrow, im buying new head light bulbs anyways so just a days work on the car haha

 

Yep.. They'll do that. For a long ass time I wasn't able to find one local. I stopped at a AutoZone out of town and they actually had them in stock. So I bought all of them lol.

I replace mine after every 2nd oil change. It's not needed, but I do it any way. When my old one was in, the car ran a little rough at idle, and I was burning a shit ton of oil. I knew it wasn't my rings or valve seals, either. Replaced the PCV and boom, no more oil burn.

 

hmmm strange my oil seems to be fine but i could just be blind haha, going to buy some today, they have a crap ton in stock haha every second oil change seems legit though keeps the engine runnin clean
