Completely agree. But it gave me a lot of practice messing round with different gaskets  ;D

If the car started and was running fine before you did the cam covers. And now you're left with stalling and code 19. And you unplugged the crank sensor. I'd be checking the connection you disconnected. If all is good then I'd stick a new sensor on and see what happens.

Also, regarding the cam covers. If you're using shit aftermarket ones (and they are all shit; I say with great sadness when I think about the cost of the genuine) I'd add a bit of sealant to a few key areas in the cam cover grooves. Stick the gasket in. Let that go off. Then fit the cam cover. Then you can concentrate on the seating of the half moons instead of fighting a gasket that just wants to fall out.

I'm guessing (don't know for sure) that the OE gasket would have little nubs in to help keep it in place during fitment.

Just my thoughts  :)Thanks for your thoughts Webby, much like mine.

To reiterate: I fotted aftermarket gaskets to right hand side cam cover, no problem. I fitted aftermarket gaskets to LH camcover, the one with lousy access, and it leaked. I replaced LH gaskets with used Gm gaskets, and did it more carefully, removing scuttle and front aircon pipe mounting -leaked again. I replaced second lot with new Gm gaskets, and using a new tube of sealant, sealed OK. Then engine started badly and wpuld not idle - air leak- so I removed plenum which improved things, but engine still stalled. I replaced crank sensor with known good sensor, now all is well.

All the gaskets had ribs on to retain them in the cam cover. Crank sensor failure was unfortunate. I did check that the original crank sensor was firmly plugged in before I replaced it.

What a lark, eh? It all began with an oil change and finding an oil leak. I still not have changed the oil. Next job is to change the wishbones to correct wandery steering, pulling left on braking. Current wishbones are ATP, fitted March 2014, 35000 miles ago. I persist because this car has very little rust, unlike my other Omegas.

Why should changing the oil filter from paper element to spin-on affect how much hot oil gets on the crank sensor?
Because the buggers frequently weep, particularly the cheap no-name ones, and make such a bloody mess to drain that oil ends up everywhere.

That's why they were replaced with the newer type - it sure as hell wasn't a cost cutting measure ;)

I've got to be honest, I like the paper filter set up.  :y

One question though. What size is the socket (Allen?) to tighten up he housing to the block? Haven't done it for a while...

That applies to the lid, not the retaining bolt ;)
