PCV? like EGR?

[VRV6BT1]

G'day,

Have been thinking lately about my old VK, it had EGR on it and we disabled the system with balbearings.

I believe that the PCV is much the same principal, are there any advantages from disabling this system on a buick 3800?

Are they're any other little tips or tricks such as this they may be beneficial?

[Doctor Bob]

no advantage at all,it would more than likely cause damage

[Peanuts Inc.]

if you block off the PCV system you will more than likely blow out the rear main seal and cause a nasty oil leak as the combustion gas blow-by has no where to go but out the weakest point which is usually the rear main or crankshaft seal

you don't want to block it as mentioned already, however you can alter it for better results.

the problem with the PVC system is that it lets oil vapours back into the intake manifold/combustion chambers. simply, this is not good in the long run as it leads to contamination of the spark plugs, fouled valves etc leading to reduced performance from your engine.

the best thing you can do is add a catch can to the PVC system, this will remove the majority of oil present before reaching the intake manifold

Ok sweet, that sounds like what I'm after.
if I was to install a catch can into the PCV line would that decrease the amount of oil in the system?

It doesn't use a drop of oil at the moment.
Also how frequently should I check the catch can system for oil? Weekly, bi weekly, monthly?

i used a monza catch can that i picked up at supercheap. it's been on there for about 2 months now and there is a small amount of oil in the bottom. i intend to empty it when i do the oil changes. there is however no more oil buildup in my TB

there are some pics in my ride thread (page 5)

basicly its there to stop polluting the planted and killing mother earth, its designed so all fumes from the motor get a chance to get burnt and go through the cats before entering atmosphere,
you see alot of motors that use thoughs tiny little air filters on the rocker covers instead of pcv valves, does the same thing just pollutes more and usually leave oil fume stains around it,
or as immortality said use a catch can, catch can would problely be the cleanest option

[VRV6BT1]

How much did u pay for the can from supercheap?

[vn calais manual]

arent catch cans also illegal?

why would it be illegal? as long as you don't vent to atmosphere you should be fine

[Pub24/7]

they are legal if they return line feeds back intothe engine... most people dont do that though and dont have drama's

[immortality]

if you set the catch can up properly having the return going back into the intake shouldn't effect the engine at all.

i also believe that having the engine under a constant vacuum aids ring seal. apparently, if you run a proper vacuum pump you can run low tension rings and the vacuum created by the vacuum pump helps to seal the rings properly, you can make power this way(actually your reducing the power losses due to friction but it's the same end result). so keeping a standard engine under vacuum should also have some advantage

[VRV6BT1]

So if I was to install a catch can where do I install it?

Coz I can see two points to install it.

The best place I can see is the small line running between the intake and the throttle body.

Would that be the best place?

Or should I plumb it in at the front of the inlet?

i would mount the can on the firewall or somewhere similar hose coming from pcv going to can then back to its original location on the TB
