Just out of sight of in that pic, behind the blob of sealant, is an oil hole. This should not be blocked!!

Soz, cant answer the green sealant Q

[Webby the Bear]

ok thanks TB. LOL I know im going to balls this up

I do confess that it's a job I've only been involved with once (Ian_D's car), but reading the description you gave & what you said Mark had said, this is the only place I can think of,

so in answer to your question of where it'll ooze from .... yes! But you only need a smear, so don't expect it to ooze out too much.  and careful of the oil hole that The Boy mentioned. 

[Webby the Bear]

ok cheers matie 

[Webby the Bear]

ok bit confused chaps....

took the end cam cap off and it looks like the oil passages go through the whole of the bottom of the cam cap and also the head where they attach also. are you guys sure I should be putting any sealant in this area? when I put this sealant on and refit the cam cap theres no 100% im going to leave this oil way clear

[Webby the Bear]

ps this is me just giessing that the semi circle ''track'' running round the bottom of the cam cap has oil going through it

[Andy B]

On  seconds thought, you're just putting a spot of sealant towards the front of each side of cap ...... you're just making the front of cam cap oil tight

Remember that each cam bearing cam should go back where it came from - they're line bored and so a matched set to a head - assemble all the cap on the head over the cams & very very gradually tighten them all up evenly & progressively until they're fully nipped up. Then use your torque wrench.

That's a good example of why you don't use the RTV sealant there, as it looks like someone has. You need something that only cures in the absence of air.

Those passages deliver oil to lubricate the cam bearing, and also allow oil to drain away from behind the camshaft oil seal. They have been partially blocked by previous work by the looks of it.

Clean the passages out and put a tiny smear of the green sealant on the front of the head, forward of the two diagonal passages that relieve oil from behind the seal, i.e. just the faces either side of the oil seal. Too much sealant and it will squeeze out on tightening and block the passages. This is the passage that TheBoy referred to earlier. Block it and the oil seal will leak!

 Fairly sure green sealant is 1#90542114   Gr.8.768  15 03 170 thats the info on my tube.

[Webby the Bear]

Thanks for the info guys. think i got it. a SMALL amount 

thanks for the part number also robson 

[Marks DTM Calib]

Yes, a small wipe.

As for the manifold gaskets, if they are the old composite ones then bin them, there is an updated metal multilayer one that is MUCH better.

As for silicon sealant the silicone can also damage the cats and it wont withstand the temperatures associated with the exhaust system.

If the front pipe to manifold gaskets look ok then re-using them is lower risk adn there not to demanding to change if there are issues (where as manifold gaskets are)

[Webby the Bear]

Yep fair play Mark ill swap them out. i dont remember a gasket coming off the downpipe to manifold connection and after double checking with martin i was right. if i inspected the downpipe is it likely id find a baked on gasket?

ok, when im putting this lot together where should i lubricate with oil? im thinking valve tops, tops of lifters, under cam caps (ones behind front ones)?
