What is the function of a pcv valve?
The purpose of the PCV valve is to regulate the flow of crankcase fumes into the intake manifold where they can be burned. Prior to 1963, cars had no PCV and used road draft tubes that just left the hydrocarbon emissions from the crankcase out into the open air. The PCV valve also has a secondary role as a check valve, to prevent flow back into the crankcase. This prevents potential ignition of the crankcase fumes, should the engine backfire. The PCV system is also crucial for to proper engine sealing. The system alleviates crankcase pressure, which can push out on seals and gaskets, contributing to oil leaks.
What size alternator does a 350 chevy engine need?
The engine doesn't need an alternator. The vehicle it's sitting in does. If the vehicle is very basic, has no electrical accessories, a 36 amp would be enough to keep the battery charged. A vehicle with common accessories such as electric windows and locks should have a 63 amp or greater. A vehicle with a winch, high output sound system or other high-draw accessories should be 100 amp or higher.

If you don't vent your crank case in your Chevy sb will it cause coolant to go to your crankcase?
No, but your crankcase should be vented anyway. If your getting coolant in the crankcase it is getting in from a bad head gasket or cracked head or bad intake manifold gaskets. If you don't fix it soon your engine will be toast.

What is the crankcase oil capacity for a 1980 Yamaha Enticer snowmobile?
I have an 1980 Yamaha Enticer 250 (ET250D). Here's what the sticker under the hoods says...The oil capacity for the "Chain Case" is 15.21 oz (or 450 cc).If you are talking about the engine crankcase, there is no oil in the crankcase of a two-stroke engine. It is lubricated by the oil that is mixed into the gas.I am not sure what weight oil to use. The dealer told me to use Yamaha Chain Case Oil (but he didn't know the weight of the oil).Hope this helps!TK
Should A 1974 Volkswagen bus be turned on to check the oil?
No, leave the engine off to check the oil. When you start the engine it sucks all the oil out of the crankcase, so none will appear on the dipstick.
