Title: TDI style PCV system on 1.6td. Does it fit?
Post by: Ortho Stice on May 28, 2015, 04:43:01 pm

I have an '83 Quantum turbodiesel and it has blow-by that's causing what I would call mild runaway. I've done a lot of reading on the subject and it seems that the band-aid "solution" is to vent the crankcase into a tee back into the intake as well as putting one of those handy cam baffles under the valve cover. Because I have a Quantum, there is a block off plate on the block, not the piece with the hose barb.

My question is this, does anyone know if I can just throw the breather hose and hockey puck from a TDI on? As far as I can see it should mount right up and accomplish exactly what I'd like; crankcase vents back into the intake along with the head.

This breather hose for reference:

and this hockey puck:

I have access to both but they're not easily accessible so I thought I'd ask the boards first. Plus, if this does work it seems like a pretty elegant OEM+ solution to a problem lots of people (who for one reason or another aren't interested in or inclined to rebuild) seem to have on these old IDI's.

it will definitely bolt on and i have seen it done before.  the only issue i would see is that the 1.6 block is slightly shorter than tdi, so u might have to section part of it and make it a little shorter

Thanks! It was actually way easier to get those parts than I thought it would be and they do in fact bolt right up without any clearance issues.

So for anyone searching for an elegant solution to excessive crankcase pressure; go ahead and use TDI parts!

I would love to see this installed, and how much was this to acquire? What are the part numbers / year TDI?

Have you noticed a difference with blow by and oil?

I've always wondered why the old 1.5's had a similar system, then the 1.6's just had a plate bolted up, then the 1.9's went back again to the breather in the block setup...

 ??? Why did every generation of VW diesel get the block ventilation except the 1.6?  ???

I put one of these on an old worn out 1.6 that had tons of blow-by coming out of dipstick and oil filler thinking it would miraculously cure my oil consumption.
It still consumed/leaked an awful lot, so not sure what it really accomplished.
All the seals/gaskets in the block probably thanked me, I'm sure it relieves some pressure and stops weeping a bit...

I had 2 of these complete sets for sale recently, but they both sold quick.

I'm going to run one on my 1.6TD Caddy just because I think the set-up looks cool.  :)
