FS: 911 ST Preschona Oil Pressure Relief Valve

This is another photo of my preshona mk1 installed (without engine)

Attachment 470384

And remeber you need also this little tube to attach preshona valve to inlet engine oil tube.

Attachment 470385

The last photo you posted is a "914-6 GT" factory oil line with a '914' pn, in fact, it is my OEM and NOS part which I also reproduced for a friend many years ago.

See pix below...

Andrea, are you saying that the ST used a 914-6 GT oil line? Was not aware... :rolleyes:

Andrea, you posted this photo. Note the small solid oil line indicated by the red arrow...

Attachment 470389

Now look at this 'Aluminum' solid oil line which I purchased at the 2018 Literature show.

Attachment 470390

Is this the same part as in your photo?

Attachment 470391

I could not find a match to the p/n written on my piece.

Attachment 470392

I knew it was not a 'street part, but rather a 'racing' component--unable to correctly ID, I forgot all about it.

Could you verify for me??? :cool:

This piece of the puzzle is solved. Thx!

Did the "911 ST" use it also? I have no such photo...

Thanks Jim! So a 904 part?

The NOS piece I have is Aluminum and has a hex at both ends, appears more like the one shown in Andreas pix. That said, the p.n. scribbled on my piece is the same 904 p.n. as you indicated. A bit confusing still... :confused:

904 case fittings

Just walked in from San Clemente! Over 150+ views since last count when we left this morning. Must be an interesting topic? :p

Hi Ernie, thank you for the exploded view diagram. Jim is correct, the p/n written on my piece is for a '904' and NOT the correct p/n for my part. Obviously an error.

A big THANK-YOU to both you and JimmyT for clearing this up.

So, to complete this lesson; what exactly is the correct part number for this part, and--is it a 911R, or a 911 ST component?

Attachment 470488

:confused:

Armando, the oil filler is correct for ST cars too ...

About the 914/6 gt tube , I posted a wrong photo! It was a photo from YOUR website! Sorry

It’s not the oil tube correct for a 911

this is a close up with the flexible oil tube directed to the engine..

Attachment 470491

And now you can see with this photo the correct rigid oil tube with the special connection for the flexible one from preshona valve. It’s a quite complicated stuff!!!

Attachment 470492

finally, about the little 911R connection tube you posted , i’ll Try to find the correct p/n.

Ciao
