F134 Coolant Bypass Connection, Replace?

ran the crank case hard line tonight, and got a new waterpump and thermostat on there.

I got to thinking that I'd rather make hard lines for the inlet and outlet of the oil canister, rather than replace the soft lines with new soft lines. I have plenty of hard line material.

Any reason they shouldn't be hard lines?

 

The people at Willys must have thought so.

 

Again, I don't think the action is quite so simple. I believe it allows some venting at conditions. Dismantling mine it seemed to have a center position at rest, not a simple "normal closed."

 

the vacuum tubes are hard line, as is the fuel lines, so I was just figuring the oil lines could be too? I usually put soft lines inbetween a hardline that is on the frame going to the engine but these oil lines are going from the engine to the engine

 

I cleaned my valve out in an ultrasonic cleaner, couldn't figure out how to take it apart, but there appears to be no moving parts, and a very small hole through the center

 

They will come apart. And there are moving parts.

But you need to be very careful to note and maintain the order and orientation of the internal parts.

 

ok, I'll order a soft line then

Is the hard line on the vacuum/pvc setup factory? or was that made hard line because it doesn't matter as much if it cracks?

 

is it because the oil canister is hanging off of a bracket, and might have some movement/flex to it? Just trying to figure out why one is hard line and the other is soft

 

Well, I stand by my ignorance. So there.

A PCV actually reduces flow when 'full open.' So it is not quite a simple check valve.

 

it seems pretty solid to me when I give it a shake, but I guess if there was a soft line there from the factory, might as well replace it with a softline.

 

I've had the entire filter bracket fatigue and crack....

 

I guess Ive been lucky, or my habit of checking nuts and bolts has paid off, lol! I've never had any brackets, bolts, hard lines or anything else crack and break on me, except for when trying to remove old bolt.
