using oil

rollin315s · Feb 18, 2012

Car is going through roughly 2qts a month. It doesn't smoke and its not leaving an oil spot on the ground.
It gets a little oil on the driver side valve cover but I can't tell from what. Only engine mod is a typhoon intake.
I also drive it 5 days a week 70 miles each day at a pretty constant 2k ish rpm, no loss of power from what I can tell and is getting good mpg
How can I find out if my cat is getting blow by?
How can I tell if my pcv valve odds functioning?
If I cap of the vacuum line coming off the valve cover would that help the pcv out?

Thanks

Check the radiator just in case for HG

Coolant is nice and green. my friend suggested that my intake manifold gaskets could not be sealing. Anyone else second that opponion?

where on the valve cover are you getting oil on? I would suggest checking lower intake gasket and valve cover gaskets. cheap gaskets to replace for some security and hopefully able to find out whats causing it! otherwise you may be burning oil also. with that much oil, i'd be scared you're burning oil...

Ill take a picture of the valve cover later. I just left. I swapped the short block a few months ago and I put in what apeared to be a good shortblock from a reputable local guy. The cylinder walls still showed the hasp marks and didn't show any signs of the rings not scrapping the walls evenly. I also put on a cheap o felpro gasket set. I might just have to put on some 1250s and see wt happens. How can I check for burning. Will the plugs show signs?

Plugs will show. You can also take the cover off your typhoon intake and see how greasy and oily it's in there.

normally if the intake gasket is bad it causes a vaccum like leak and the car will idle bad and run rough.with using 2qt's a month it'd have to leak some or burn it.since it's doing neither it's a strange thing forsure.like said above,pull the plugs and look at them.

Pull your intake off your Throttle body and have a look around in there. Ive seen them push oil out through the passenger valve cover right under the oil cap up the hose into your intake tube and all through your tb/ intake.

pulled the cover plate off of the intake and found a bunch of oil. it looks as though it might be coming from or going to the vacum lines, im gona pick up a new pcv valve and see if that helps any. the throttle body side has no oil

my friend suggested a leakdown test if the pcv doesnt fix the problem. any other suggestions?

That's why I said to take the cover off, I read something about this style of intake (same as edelbrock) that talked about the uppers always being full of oil. It's something in the design, I'll search through my history and see if I can find it. Obviously there isn't 2 quarts of oil there but it's a start to find the source of your problem

rollin315s · Feb 19, 2012

I read up on that and found that the performer and typhoon had a mistake in the design and that they put too much vacuum on the pcv. my friend said I could just run an open pcv valve system. Gut the pcv and put in a catch can then to the valve cover. Anyone else runnin a pcv system like that?

verify that the lower intake has a oil baffle for the pcv... if it does not then you will ingest a lot of oil into the motor.

rollin315s · Feb 20, 2012

Is this the baffle you are referring to?

thats the baffle.

94RedGt · Feb 20, 2012

Wow this looks weird. A friend of mine has that very same intake and he to had some sort of pcv problem, maybe what you could do is run a valve cover style pcv system , but u also gotta make sure u have the baffle in the valve cover or else ull get the same result. That baffle looks tiny compared to the one the stock system has that could be the problem because i honestly dont see any other way for oil to get inside the engine, you could probably run a much smaller vacuum line to the pcv.

rollin315s · Feb 20, 2012

its already hooked up to one of the smaller ports on the intake. i think wt im gona do is just run an open pcv system like my friend is. just gona gut a cheap pcv, run to a catch can and then to the valve cover and cap the vaccum port in the intake and at the intake elbow. that way it returns the oil that gets sucked up into the line and still vents the crankcase pressure.
