oil pooling in lim

[nascartech]

hi guy s i have oil pooling in my lim and was wondering what the cause would be i thought the lim gasket anyone know here is a pic its i s pooling in the back passenger corner and front drive corner thanks

ah, you noticed what i notice every time i pull my UIM off. That is ok and normal. It's oil getting past the pcv valve. I can't remember exactly why but i heard its normal and nothing to worry about. I just take a rag and soak the stuff up when i have the UIM off

could it be caused by a faulty pcv oh and i put up pics of the hv3

I just replaced my intake manifold gasket with the new aluminum one last night and I saw this EXACT same thing. I couldnt find the damn pcv valve though I was looking all around the intake but it was nowhere to be found? Where is this thing?

its on the passenger side of the UIM underneath a cap you can twist off.

hey bio would the oil be caused by bad lim gasket or pcv

It would blame the PVC, I did my LIM 3k miles ago and I just recently added a HV3 and mine was the same way

[Warbeaver]

its not a bad pcv. i've used several different new ones. current one is an ac/delco and it does the same thing. its not hurting anything having oil down in those pockets

PCV is to blame, its not faulty, that mess is just common.

The piston rings can be worn, and are allowing blow by, or the piston gap is large enough to allow blow by that way as well.

When I built my engine I set my ring gap larger because of the supercharger, and nitrous. Because of that, and driving it on the street, I get blow by, and my LIM has a nice film of oil on it as well.

I am currently setting up a catch can to divert, and catch all the oil vapor before it goes back into the intake. Its tricky to do with a L67 because the PCV is inside the supercharger housing. But I have a way.

Plan to do a write up on a "how to" mod. so be looking for that in the near future.

And people say I'm full of it when I tell them that a "little" oil consumption is normal for an engine...THIS is why it's normal for an engine.

Naa, its not just the PCV system, some oil is always left behind the rings otherwise the compression rings wouldn't have any lubrication. valve guides also need "some" lubrication.

IMO some oil will *always* be burned on any engine. Its when it starts slerping a quart down every 1K i get concerned. I had an 86 tbird that was doing a quart of 10w40 in 300 miles I think it had issues.

[Bio248]

for a bike 'normal' is defined as a quart every 500 miles.

you guys got it easy.

EXACTLY

In fact, if you constantly beat on a supercharged car, race it, drag it, then it WILL consume about a quart during changes....I've experienced it, and I know it. If I drove like a normal level minded person on the highway, like say, on a road trip and rarely got into the gas, then it wouldn't use any at all.

Let's just say, on the Power Tour a few years back, I had to top it off once before we headed back home. That was 1800 miles of hard drivin'.

hows your car running now anyways?

Bio : tho its not really a "bike" one of my atv's is a yamaha raptor 660 and it uses a nice amount of oil. Last time I paid attention it seemed like 1/8 a quart every 8 gallons of gas or so. But I beat the crap out of the thing.

Everyone I've known with a yamaha 660 says the same thing. They eat oil yet i've never seen any blue smoke.
My raptor 350 uses close to nothing.

[Bio248]

it's cool, my car burned a little oil, but i just let it go and said that i was keeping everything lubed.

[TorqueAutoMotiv]

ive had a few intakes off on the 3800's now ive never seen one with out oil must be fine

I think GM wants to see a documented quart every 750 miles before they'll talk to you for warranty work.

As for your T-Bird... well... it's a Ford...

"I think GM wants to see a documented quart every 750 miles before they'll talk to you for warranty work. "

According to the TSB on valve steam seals its a quart every 2K.
