Oil tubing to hollow camshafts

[pss]

What is the correct look for 20 en 21 below, the oil feeding tubes to the hollow camshafts? I have tubes fitted with steel armor on the outside, is that correct?

The center oil cams did use an metal armored oil line. They used a galvanized wire braid. The manufactures chose different color thread tics to identify their brand. The two crimped hoses are from Porsche for center oil cams. The other is Coline brand. The wire darkens when exposed to the air. The bright crimped hose was in a bag, the other left out. G.Led

Wow, more behind this than I would have thought. Txs Led.

Hello PSS,

TCH (Thechno Chemie) made all of the center lube oil lines. Back in the 60s they had a specific plating combination and tracer braiding color combo. The tubes were clear zinc and the crimp collar and nut were yellow zinc. The steel braiding on the hose had a blue tracer with two tiny red thread tracers. Later in the replacement lines in the 70s and 80s had the blue and black tracers. As Gordon mentioned each manufacturer had a different color as their signature. Cohnen (Cohline) had an orange tracer and TCH used blue.

I make the center lube cam lines and will be happy to help you.

Thank you,

Brad

What about the to-return oil tank tubing? You also show one on yr picture Brad. Were both tubes armored like this right from the start 1964?

Hi J,

The 64 and very early 65 cars used Argus lines for the scavenge and feed. Argus lines were always used on the race cars and often in prototype situations. 300 950's are the last cars I have found Argus lines on and 301 920's are where I have first found TCH (BraideBlue Tracer) oil lines used. The TCH (Steel Braided / Blue Tracer) lines were used all the way up early 68.

Thanks,

Brad

Jacques,

Here is a picture of the Argus scavenge line.

Best regards,

Txs Brad.
On both my cars (300700 and 301379) I have rubber lines for the long and armored for the short tube. So they should both be of the armored type then?
The fittings in your last pictures look different from the one in post 4. What is correct for 1965?

Hello J,

The crimped line with blue tracer is a TCH line. The yellow gold collar line is an Argus assembled line. Your 300 700 car would have Argus originally from the factory. Your 301 379 car would have TCH lines.

Thanks,

Brad

So Brad, that would be a early 1965 change. How do you know this? Which engine/car number did this change take place?
