Topic: Detailing PCV tube

[J_Speegle]

What about the brass 90 that connects to the pcv valve, is it also painted?

IMO sometimes - just depended on where the painter got the paint. Have original examples where the paint ended (soft sprayed edge) between the bend and the PCV block while others have spray out to the block and overspray on the PCV

The photo below was posted in a recent ebay auction, with the following description:

The two LHS ones  are for a 428CJ, the third one is the 68 GT390 - they're very similar but different - the final tube is for a 390/352/360 PCV setup as defined by the angle of the nipple on the tube to acount for the difference in intake manifold height between the engines in question.

Is that an accurate statement? Are there tubes with different nominal angles? Or is there one design with a fair amount of variation at assembly?

Yes ,different angles on pcv hose nipple. Also different ends for different forward fitting placement.

+1 different angles = different applications

While we are on the subject of the PCV tube and the fittings, should the fittings be painted or bare? I have seen photos of both. Also looking to confirm the difference between the 390 and 428 fittings front & rear on the intake and the vacuum tree, assuming there are different applications.

Thanks

The one that isn't painted is the accessory vacuum block that the brake booster tube is connected to. The other fittings are painted including the hose and clamps.
