I noticed on the guide for replacing cam cover gaskets that the vx black seslent is recommended, however I only have blue silicone sealent to hand. Is this ok to use or is the black stuff a must? Also i gathered from the guide that the inlet needs removed, are the gasket on this ok to reuse usually?

Whilst taking out the Driver side coil I was presented with this:

Spark plug drowned in oil. Wonder how I never noticed running problems? Anyone got a turkey needle :)
-
Ive seen much worse - the whole recess full of oil - so you've almost caught it in time. Ive only ever used the correct GM sealant so cant comment on alternatives. Inlet gaskets are fine to reuse over and over.

And NS takes the biscuit, back one full to the brim, others have oil in them too, and the rear spark plug boot thing came off

I hope so, not had any running probs so wouldn't have suspected it until it filled further and started running bad. Hope that boot thing detaching hasn't buggered anything else. I think I've answered my own question now about using anything other than the proper sealant!
Pity vx never installed 6 mini dipsticks so at least we could check if it was filling up!

All pretty much standard stuff.the oil does tend to soften and swell the coil pack rubbers so be gentle with them and clean them best you can with something that won't make them worse.brake or carb cleaner is designed to be ok on rubber.mine were just as bad if fact I think about 3 had detached themselves from the coil pack.all was cleaned up and checked for damage.i glued mine back on with superglue and all was well.if car was running ok before it should be ok after in theory (coil pack wise).soak up / remove / suck etc oil from plug wells you choice of method.like others will say ,I used gm sealant on cover gaskets but at the end of the day it's only a silicone sealant so another brand should be ok ,can't see why not.

Whilst cam.in.head's comment re sealer makes perfect sense, considering the work and aggro involved in replacing the cam covers, isn't it worth the fiver or so that Vx want for the recommended sealant?
Just to add, Serek did mine a year or so ago and my plug wells were brimming with oil and he warned about the likely need for new coil packs, because my rubbers were cracked and loose.
However (NOT to tempt fate, so shhh.....), they have been fine so far, no misfiring.

Will give them a clean with WD plus hose the oil out the plug holes with my garden hose (KIDDING :) ) hopefully should be ok as it looks more or less dry in the plug apertures on the packs. I imagine the rubber seals pretty well round the plugs so not much if any oil would have got inside.
-
Before I got to the "KIDDING" bit, I screamed internally as I read the first bit.
Ok, you got me! :-[ :y

You imagine wrong... any oil in the wells for any length of time and the boots eventually perish... they are ultimately variations of the same chemicals... if you've a misfire, then you're too late. Sure you might get another 6 months out of the boots once cleaned and dried and any oil leaks sorted, but don't expect them to survive this process ;)

Looking at the NS coil against the OS it looks worse underneath and there are a fair few wee cracks appearing where the metal inside has been rusting. Personally I'd like to replace the rusty one, is it that bad though or is this just superficial but will still hold out? I'm also concerned that when I was cleaning out the oil from inside the rubber boot, where the spring sits, the plastic collar disintegrated. As in first pic, might not be very clear but half of it fell off.

Better looking coil - no rust. Think this has possibly been replaced at some point

Lol I hope you didn't think I really meant it ?

Might as well mention this too, was cleaning out the breathers and tried cleaning out the two little pin holes on the top hat bit however when I block one end of the plenum breather thing - the 4 pipes - and blow through it nothing comes out the little pin holes? Yet I can stick a thin wire right into it.
Top hat with 2 pin holes. I was actually wondering if I could get a wee tune out of this, sort of like pan pipes but made by vauxhall!

I'll have mayo with that. The Y shaped pipe at the back was also clogged well up.

Nope - the "KIDDING" brought my heart rate and blood pressure back to normal! :y

Glad I was a sort of calming influence there then :)

Rust indicates the presence of moisture, usually from the scuttle... It will only get worse ;)
Misfires are caused by one of two things... Oil reducing the current flow and moisture degrading the coil pack. Both lead to misfire codes.

And this being the coil that sits under that bit of the scuttle that projects out a bit more tan usual would make sense. Havent had much rain here recently so hard to see any water or proper dampness although a wee bit of the foam i though seemed a wee bit damp.
I was asking earlier about the little top hat with the two pin holes in i, which is on the plastic breather, seem blocked when i blow through it but the pin holes seem clear. Any thoughts on that one from anyone, where do the pin holes vent to on the plastic breather?
-
Larger of the two middle pipes goes to the purge valve and the larger holes on the top hat.
Smaller of the two middle pipes goes to the small outlet on breather box at back of 135 head and the smaller holes on the top hat.
If you can't blow through then they're still blocked.

Ok i was blowing through the other 2 pipes that sit at the front while blocking the 4 pipes at back and no flow. I'll try what you suggested thanks.
I also found a very thin round rubber gasket, thinner than rocker covers ones that sit on securing bolts, i think goes on the plastic plenum securing screw.
-
The outer two pipes run the full length of the breather bridge and connect the throttle body to the large spigot on the breather box ;)

Incidentally, that Coilpack is toast.

Got another bosch one winging it's way to me now. The back securing bolt on coil and rocker cover are rusty on N/S. Hint hint!

Were you taking pictures when my back was turned yesterday? Pretty much what mine look like.

Yip only one way for this coil and that's downhill!

All pretty much standard stuff.the oil does tend to soften and swell the coil pack rubbers so be gentle with them and clean them best you can with something that won't make them worse.brake or carb cleaner is designed to be ok on rubber.mine were just as bad if fact I think about 3 had detached themselves from the coil pack.all was cleaned up and checked for damage.i glued mine back on with superglue and all was well.if car was running ok before it should be ok after in theory (coil pack wise).soak up / remove / suck etc oil from plug wells you choice of method.like others will say ,I used gm sealant on cover gaskets but at the end of the day it's only a silicone sealant so another brand should be ok ,can't see why not.
Really :) what brand do you use then ??? Ruddy stuff I use damn nearlly melted me wubber gloves at the weekend ;D

The boots don't need gluing on. They're a separate part designed to be replaceable and available separately. New coilpack should include them, but they areca service item ;)
