a quick question about the engine

what part is this and what is it for because mine does not have that there and is that a bad thing



and oh yeah another problem is that when i give it a lot of i think about 15% or more throttle when it is on low rpm's it bogs down like it is getting to much gas, but it does fine when i am above 3500 rpm from then on i can put the peddle to to metal. could i just need to fuel/air ratio adjusted or what.

Re: a quick question about the engine

thats your PCV valve. if you don't have it, what do you have? a hole in your valve cover?

Re: a quick question about the engine

Yeah you can find a nozzle that fits at Autozone, and get the vacuum line for it too, or just a breather filter.

Re: a quick question about the engine

yea there should be a pcv valve there and a hose going from that back into the intake manifold, i replaced mine, cost like less than 3 at advance auto. but looking at your pic, i dont see where the tube would go. the first pic, you can see it can fit in the top right hole, but yours, the top right bent tubing, it looks like the hose goes to the right..to brake booster? in the normal stock manifolds actually, brake booster hose goes and fits behind the manifold, but that seems like aftermarket. usually, going from left to right on the manifold, its fuel pressure reg. and then pcv valve. heres a pic of mine. red valve cover with ngk wires on Flickr - Photo Sharing! hope that helps a bit! hmm nice fuel rail and fpr btw

so to answer your question. yes. there is an open hole in his valve cover. shouldnt that thing be spewing oil like a BP oil rig?

Re: a quick question about the engine

Hey that hole is very important ,its a way for the engine to breath unburned gases. so don't even think of blocking it,it will cause your engine to leak oil all over and your seals and gaskets to leak

Re: a quick question about the engine

PCV (Positive Crankcase Ventilation) not PVC (Polly Vinyl Chloride), and it goes from your ventilation valve to your intake manifold, you have the picture posted in your original post you can use for reference.
The nipple you have your brake booster vacuum line attached to is where your PCV should be connected to your intake manifold, your brake booster line should be attached on the rear of your intake manifold.

EDIT: Considering your Intake manifold is not OEM you may not have a connection for PCV
A: Replace your 90* nipple with a T-connector
B: Install a small breather filter to your PCV inlet on your valve cover

Those are your two current choices but leaving it open like that can lead to moisture in your oil and engine block or debris getting into your valve train neither very pleasant.

Re: a quick question about the engine

just bought the pcv so nothing can get in there now buy do not know where to hook the hose up to. Now how about the other question when i give it about 15% or more throttle when it is on low rpm's it bogs down, like it is getting to much gas, kind of like when you are in to high of a gear but worse. It does this in the lower gears and its fine when i am above 3500 rpm from then on i can put the peddle to to metal. could i just need my fuel/air ratio adjusted or what.

Re: a quick question about the engine

Find a T fitting and cut your booster line put it in and route a hose from your PCV to the fitting.

Do me a favor could you take a picture of your intake manifold check for a large nipple on the left top area of your IM.



A little more explanatory of original routing...

For your bogging you could try replacing your Fuel filter and Air filter for starters but to diagnose a problem like bogging requires more info. It could be a vacuum leak, clogged injector, fuel restriction, partially open EGR valve, bad timing, faulty distributor, spark plugs, ETC....

What maintenance have you done lately?
