pcv on manifold burning oil

does anyone have tips on doing this to the pvc pipe cause my engine is sucking about a qourt every 3 weeks and no sings of leaks on engine converted over to breather filters on mine (just put breathers on each PCV port)

I'm not sure what you're asking...how to convert from a PCV system to breather fiters?

yea thats exactly what im askingand does it take anything away from oil circulation i dont know too much on how the system works

It has nothing to do with "oil circulation", it has to do with venting the crankcase vapors and crankcase positive pressure. When the engine is running, there will always be a certain amount of "blow by" that makes it past the piston rings. This forms pressure in the crankcase, and needs to be relieved via some form of ventilation system. A byproduct of combustion is also moisture, which ends up in the crankcase as well, and needs to be vented.

The PCV system is nothing more than a breather system supplemented by the engine's vacuum. When the pcv valve opens, the vacuum from the engine sucks out moisture and vapors from the crankcase, and reburns them in the engine.

By converting to breather filters, you are venting the crankcase by means of evaporation and the fact that vapors rise with heat. So instead of the contaminants being sucked out and into the engine, they are dispersed into the air through the breather filters. This is the way older vehicles used to operate, and the way racing/aftermarket engines are set up as well. Basically you just install breather filters in the same places that the pcv hoses used to connect to the valve covers, remove the pcv lines and valve, and cap off the pcv hose port on the intake manifold.

You can also convert your system to a ls6 system for about 90.00 dollars or so. The kit would consist of a new valley pan cover and tube w/ pvc to the intake mainfold. I will try to get the part numbers to by tommorrow if you wish. By the way, it removes the orginal pvc system from the car, which runs behind the motor and firewall.Just a other opinon.
