Hi there,

After having problems with the emission test all the years here in Germany (high CO) I started to fix the D-Jet with rebuilding the intake system to sort out the leaks.

While disassembling the thing I found some creative solutions from the PO. (IMG:style_emoticons/default/barf.gif)

The seal from the throttle to the plenum missed a piece but was „sealed“ with some gunk („Bärenscheisse“ you may have the right english word too).
Seal between runners to cylinder head had the same black paste in a crack.
Thermo switch wire was broken and drilled together with a little tape under the plenum.

I replaced most of the Vacuum hoses some years ago. Sadly not the crankcase vent.
The PCV valve was connected to the plenum but there was u T connection to the charcoal canister wich wasn’t easy to see. The PO then blocked the T side to the plenum with glue. So no crankcase vent... (IMG:style_emoticons/default/WTF.gif)

Oil separator gasket was glued in as well

And finally three screws of the crankcase split were loose...with one nut missing (IMG:style_emoticons/default/headbang.gif)

And some minor things...


What I did so far.
I cleaned all the parts, removed all the gaskets, glue and rust.
Painted everything.

Now the question. Should I reconnect the PCV or not? The valve operates when I apply some vacuum. How is idle stability with the PCV?

Thanks for help
