New guy questions

[madkickz]

Okay so have a few questions:

How do I remove this cover to access my windshield washer wiper motor?

Is this bad? (Second picture)

I've been running this push in breather but it's causing oil to leak out onto my exhaust. What do you suggest I do? Someone mentioned getting the stock setup but I don't have the money right now.

Thank you for all the help this forum is awesome.

I'd stick a pcv valve in there and plumb it to your carb or manifold,even just let it vent.

If you don't have a PCV valve, get one. It takes the pressure built up in the crankcase from the seal of the pistion rings and feeds it into the motor instead of a)venting to the atmosphere giving a burned oil smell or b) forcing oil out of anywhere it can. Normal carbs have a big 3/8 nipple near the base for a PCV hose. Just use 3/8 fuel hose.

Also the rubber boot on the steering isn't too much of a concern if your steering still works. Short term fix, duct tape if it bothers you that much. Not too tight, just enough to cover it. As for the wiper motor cover, there's bound to be clips or screws somewhere. Don't be surprised if you break it. 80s GM plastic is not the best over time.

Oil leaks can be caused by improper crankcase ventilation. For anything that is going to be street driven you need to have a properly operating crankcse vent. system. This includes the PCV valve (Positive Crankcase Ventilation). The PCV relieves the crankcase pressure at idle and when cruising, basically anytime the motor is in a high vacuum condition according to a vaccum gauge installed/hooked up below the throttle plates of the carb. The second part is a hose hooked up in some manner to a valve cover that is attached to the air cleaner or carb somewhere above the throttle plates. This hose will relieve crankcase pressure when accelerating or at WOT conditions. Many aftermarket valve cover breathers aren't designed to work with a stock system. They vent to the atmosphere which will work, but no where near as well as the factory system. And quite often one of the effects of using them is what you are describing.

Keep in mind that every motor has a certain amount of crankcase pressure and no matter the condition of the motor it will have some - and it needs to be addressed or you can expect what you are seeing. With that said, a worn out motor that has a poor piston ring to cylinder wall seal will have an excess amount of crankcase pressure which will result in oil leaks from most anywhere that a motor can leak. A compression test can be somewhat helpful in determining this, but a cylinder leak down test will give mmuch better results.

I don't know if you wanted all of this info, but from reading your post it appeared that you might not have a proper carnkcase ventilation system hooked up, so I thought I'd describe it with a little bit of detail.

Hey guys I installed a new pcv valve when I bought it. All your info ha been great. It sounds like I need to run a leak down test on this baby. Maybe the 350 is coming sooner than I thought. I'd like to get more life out of this ole 305. We shall see.

You can get a push in breather with a hose nipple on it. Many aftermarket air cleaners have a provision for connecting a breather hose to them. I would want some sort of breather filter like the stock setup to catch the oil vapor though. The stock setup is really well engineered.

Could it be just a leaky valve cover gasket? My V6 did that something terrible and it turned out to be a bad gasket. Is it at the base of the vc or is it dribbling down the top onto the manifold?
