Engine builders advise, rockers arms and shaft
Hi all, So rebuilding a W code 1700 engine. Put a new everything inside. Bigger B+P into 2 liter heads, but I need advise regarding rocker arms and shafts.
2 liter heads didn't come with rocker assemblies and the 1700 rocker arms are wrong.
What rocker arm assemblies do people recommend for the 2 liter heads, and where on earth can I get them. Having trouble finding them.
Been a member for years but had to re-register as I couldn't login in.
Many thanks in advance, Jon

Re: Engine builders advise, rockers arms and shaft
W code is a Type 4 411/412 engine, originally on D-Jet fuel injection.
Look at using rockers from the 1800 / 2000 engine fitted to the T2 bay or the CU engine
Here's a starter - other people will have more in depth knowledge than me, though I do seem to recall a difference in the rockers between 1700/1800 412 engines, but I thought that was only adjusting nut size. https://www.vwheritage.com/vw-bay-windo ... s-camshaft

Hi mate, yep engines out my shed and a spare for my a 411LE and 1700 rockers are different, angles wrong.
Where I'm getting confused is the 1700 rockers are spring loaded but I think 1800/2000 are solid??
Thanks for the link.

Re: Engine builders advise, rockers arms and shaft
Is this for the 411 then ? (I have a 412LE and 412LS)
Just fired up ETKA, part codes as follows
1700 - Inlet 022 109 443, exhaust not listed
1800 - Inlet 022 109 443, exhaust not listed
1970 CU - Inlet 022 109 443, exhaust not listed
All seem to be the same
The tappets are solid in all engines apart from the CU I believe. Definitely hydraulic in the CU, I have issues with mine, definitely solid in a W engine when I rebuilt them 35 years ago. Different pushrods correspondingly

Yep I have a 411 LE variant, she's my baby and has been driving me made this last 12 month chasing issues but pretty much sorted bar replacing clutch master.
Thanks for the info, you've confused me even more. Are you talking about rocker arms?
I need to know about rocker arms and the shaft for the 2.0 heads. The ones I have are from 1.7 heads and are not correct.
Thanks, Jon

Re: Engine builders advise, rockers arms and shaft
Have a look at the diagram on the VW Heritage site
Camshaft rotates
The cam followers / hydraulic tappets press on the camshaft and follow its profile
Pushrod goes between the cam followers and the rocker arms
Other side of the rocker arm presses on the valve head, which is under spring pressure
Hope that removes any confusion, the point is that the 411 has "solid" tappets, the CU has hydraulic, but the rocker arms are supposed to be the same for both.
When you know what you want, you might have success with a wanted ad on here, or on type3and4club, I recognise you now
What part of the world are you ?

Re: Engine builders advise, rockers arms and shaft
Yes the mist has cleared...!
Thanks for the info. I will have to have a closer look at the arms I have off the 1700 heads. Test fitted the yesterday in the 2.0 heads but didn't seem/want to sit right.
Hence me asking question and bringing on my confusion..... And the fact that the 1700 arms have some wear, shafts seem ok, but arms have taken a bit of a pounding in the cups. And me asking what to use and where do I get them.
If the shaft are good, could I use these arms, or something similar?

Re: Engine builders advise, rockers arms and shaft
You could, but Ray Greenwood is pretty clear that OE is best, Porsche 914 items the best of the best. I have no experience of them
