Oil Pressure Line
« on: March 22, 2008, 06:22:46 »
After replacing the oil pressure line with a new line, is it necessary to somehow get the air out of the line and get a column of oil into it? In other words, do you have to bleed the air out of the line somehow before hooking it back up to the center instrument box?

I asked gernold this very question and he said no.

when I re-installed my instrument cluster I just hooked everything up and started the car.

you could, if you wanted to, bleed the system, but why chance the mess.

.
Of course you should do this, anytime you have the central cluster out. :)     .Both in order to bleed out any air, but also to displace the old, stale oil from the line.

Put a small cup to catch the oil, and crank the engine w/o starting until fresh oil comes out. That means, disconnect the ignition before cranking.

What's the easiest way to disconnect the ignition? Pull the center cable out of the distributor cap?

Hi Andy,

So yours must not have been the ivory car I saw at Hoyt's when I picked up Carling with her new soft top?  They used it as a model to reassemble her bits...

I think it is a Bourdon tube(the French rangled their way in).  It responds to a gas and/or a fluid equally-I think.

IMO I think its easier to disconnect from the coil than the distributor cap....but either one will do.

Trice,
My car is ivory, but I'm the only one playing with its bits... in the privacy of my garage.
