Of course you have, it’s almost the rule of thumb when working on our vans.

I just swapped in some new spark plug leads, and some new injector seals ( little ones that go on pintle cap, seating in intake manifold) and the injector rubber bushings that press against the securing bracket.

All of those items needed replacement. Especially the injector rubber. All of them were cracked and somewhat hard.

Nosing around the engine I saw a “tell” on the metal coolant line , the lower one of the pair, that crosses the engine at the front (2.1, syncro). Seems that the hose from that pipe to the bleeding ring up around the compartment, was also getting hard and slightly weeping at the nipple connection.

Replaced that, a little awkward getting the new hose on. Nothing really bad, just ... you know.

Lost coolant during that. Had to go get more, top up, and I bled at rad just to make sure. 

Changed oil and filter ( Mann w719/12m castrol 20w50 dino).

Adjusted idle, and I think the adjustment was more responsive this time. I have the distinct impression that one of the injector seals was letting air in.

It’s warm and sunny here, not cold and wet or freezing so take this with grain of salt.... Van idles and runs so much better after all this . This old wbx which i abuse so badly, sometimes really puts a smile on my face.
