I've noticed a slight oil burning smell from engine bay and decided to remove the rockers and check the gaskets and re-seal them with a bit of gasket sealer with main gasket.
During the removal I broke my extremely brittle breather pipe (again, already has 3 repairs to it!!) I noticed that the pipework from Bank 1 was full of gunked, mayo residue whilst the short pipe on Bank 2 was clear.
The underside of the rockers were both clear and no residue anywhere to be seen. Both sides were dribbling a bit of oil onto the manifolds so hopefully that's now sorted.
Why is there lots of white gunk? What harm will it do? I have cleaned it all out. I started the car and felt for any pressure/vacuum coming from the broken breather pipe from the TB, and there was nothing at all. Also, the same thing was with the breather coming from the rocker cover! Nothing.
Also, I whipped out all the plugs whilst in there and found that cylinder three plug was wet and all the others were dark black but dry. Car hadn't been started since last night. I checked the resistance on the HT lead for both side. The lead with the wet plug measured 5.11 K ohms where the opposite plug lead only measured 5.03 K ohms.
So I measured the two medium length leads and they were almost the same in resistance. Any one have any ideas if the higher resistance could be causing the missfire/hesistation?
