Lynda's "CJ" Buildup Progress

Hmm, I've never tried the first scenerio to see it's a check or not. I'll have to try and let you know - I think that it acts as a valve though.

thats what ive been reading, but i still see people use two of them...

[agjohn02]

i was thinking about the oil issue today. how long did the engine run upside down? at idle the PCV is pulling a pretty good vacuum and oil should run into the valve cover pretty quickly. the PCV was sucking oil into the manifold and filling it up while it was upside down. thats the only way i can see that much oil getting in there that quickly. theres no way that much oil got past piston rings and through an open valve. luckily it was nose down and ran out the filter. if it had been nose up it would have sat in the manifold until you flipped it back over and then filled the cylinders.

just run the PCV on the valve cover to a breather and cap the port on the TB. then roll it again and see if its any different.

I'm not sure about that part...

It was running upside down for - at most 5 seconds.

What about the other hose that attaches to the top of the TB? The hose with the PCV valve is on the driver side and comes into the middle of the mainfold

im trying to remember what it looks like. ive got the f-body manifold on mine now. ill look at the truck manifold when i get to the shop.

look on page 50

the hose on the passenger sid - top of the throttle body goes directly into the passenger side valve cover, no PCV valve

thats the one i was referring to. the f-body manifold doesnt have the port on top of the manifold so i forgot about the one coming from the driver's side.

i forgot about checking the manifold out. will do it tomorrow maybe...

messed with the line lock any? get out there in the front yard and try it out.

i thought of a good burn and decided to put it here instead of pirate.

you should have powdercoated this thing pink too, because its gonna fold up like a pair of panties the first time it sits down on a rock.

[DRAGOONRANCH]

needs more triangulation....

[DRAGOONRANCH]

I would really listen to John on this one, he knows about how limp some things can get...

look how close that skid is to the front axle. It's barely possible to even hit the pan on a rock. The front axle would have to clear it first and it's never going to hit.

Part II - the only way that the oil pan will crack will be from a "point" syle impact (a sharp point going into the middle of it). Even if for some reason, a rock was able to get past the frame, leaf springs, driveshaft, and front axle to bend the skid plate up - it will hit the oil pan as a flat surface and distribute the load across the entire oil pan. The majority of the energy from the hit will be absorbed in the bending of the skid support arms resulting in a minimal amount of force hitting the oil pan.

I have been wheeling pretty hard for over ten years and have only brushed my oil pan a few times. Take a look under anybody's rig that has 10 plus years of hard wheeling and check out the damage to the oil pan - it will be minimal - it's just really hard to hit - you never line up rocks down the center of your rig because you'll just hit it on your rear diff.

Like every decesion made in life, it's based on risk. This risk is minimal, and the protection on that risk is adaquate.

On a side note - I have seen one crack on Greg's low slung buggy, it just oozed oil in a slow drip, nothing to stop you on the trail.

decent arguement. i just couldnt resist.

Ok, so what's the consensus on this?
The driver side has a "check valve" on it at the valve cover, but the passenger side crankcase vent doesn't have anything. Should I add a check valve on that side or just plug it?
