Hi guys,

Got my cylinder heads cleaned up and my block mating surface cleaned up. Head gaskets being delivered as we speak. Head bolts from GM.

1.) What's the part number for the green sealant?
2.) What's the green sealant for? Apart from to help seal corroded parts of the cylinder head? i think Mark mentioned front bearing cap..... can someone tell me exactly where this is to go
3.) i have 3 earth leads that came off the LH cylinder head.... but i'm buggered if i can remember where / how they go on. they came off with 3 bolts but there arent 3 holes to screw them in to 
4.) is there a gasket to the downpipe to manifold connection?
5.) if i was really broke, like i am can i get away with using old manifold gaskets? as they werent leaking before

please forgive my stupidity on the abopve questions. first time ive ever done this and just making sure i get everything right.

Am about to get abused for this,by the purisit police.

manifold and downpipe gaskets can be reused, put a small bead of silicone sealent on both sides of the gasket and tighten up. You wont ever get a blowing manifold again, use clear silicone sealent from local diy shop,.

Any idea on the other questions? 

[biggriffin]

I think there's a bracket on the back of the cyl head,near the coil pack.guessing the bolts are 10mm socket,

[Webby the Bear]

hmmm. it may have come off and be laying in my parts pile somewhere  ive tried to be as sensible as possible with keeping bolts and brackets etc together. but seriously, the amount that have come off is ridiculous. 

ps, the silicone sealant.... is that just the stuff for the bathroom? got plenty of that i think

Never use that anywhere on a vehicle - unless it's got a bathroom in it.

Bathroom silicone gives off acetic acid as it cures, which will wreck lambda sensors.

I would replace the exhaust gaskets, TBH. They frequently give problems on the 2.5/3.0, so do them while you can get to them rather than have the @rse of a job that is replacing them later.

theres a metal silver bracket that the coil pack bolts onto, it has the three holes in it for the wires. DO NOT connect them all together.

I think Marks referring to adding a little under the actual bearing cap that the lip seals for the cams sit in

[Webby the Bear]

If you remove the Torx bolt that's only just in view (& its mate) this is holding the cam in place (along with the others along the length of the cam), but it also needs sealing to prevent oil escaping from the front of the head. The oil lip seal goes into the front of the cap/head ...... ignore the black sealant - it's sealing the cam cover to the head
