No error codes but i think my idle air valve is cooked. Buzzing like an electric motor that's seized and then valve just flaps about when it's got power.. can't be right
 
Gearbox and gaskets today. Not sure if THAT is really good news so...

Ah, another problem. The side cover on the gearbox, the one with the filler plug and the small magnet, was wet. So I removed it to replace the cover. Filled up with some good 20W50 mineral oil. Now the gasket is not just wet but dripping. Any ideas? Some high temp silicone or engine sealant?
 
Another question, does one have an idea which size the nut behind the hand brake of a LT95 gearbox is? The biggest one I have is a 29 mm, and that is too small... Again not my day it seems...
 
Ah ****! Well, it's too late now... One cannot have too many tools, can you?

Once everything is there, hand brake o-ring next. And I'll maybe redo the gearbox gasket properly again.

Two fun questions so. The workshop manual says motor oil for the gearbox as well. JLR is using gearbox oil now. I am asking because I have plenty of gearbox oil left (initially ordered for the axles) but not enough 20W50 left to do TC. I'll just reuse today's oil again for the gearbox.

Second question, shouldn't the lower bellhousing cover, the one in the front right next to the engine oil pan, have a gasket also around the lower edge, and not just on the top? None of the gasket sets, gearbox, engine lower and upper, has a fitting one nor was one fitted there. Because I have to use the silicone anyway, so I wondered if I don't seal that part as well. If it is supposed to be sealed that is...

Ah, final task for today was a new steering damper. And a short bike ride with my older son along our nearby river.
 
Cleaned the pushrods - they are now metal instead of looking like black paint. Also cut cardboard covers for 2 tall jamjars, with 8 holepunches / slits in with scissors. Labelled drive / pass, bulk and an arrow to one hole, arrow for direction of storage, and then inserted the correctly ordered pushrods for a final wipe down / lube / reinsertion in the engine in due course. Keeps them clean, takes up less space, less risk of losing / displacing / bending them.

Stripped the first rocker shaft ready for inspection. The rockers slide off easily but the pillars are a bugger. With the second one I think I will try a heat gun to expand the aluminium enough to slide down the shaft easier. Can recommend Autoglym engine and parts degreasant. Low odour, seems OK for indoors unlike carb cleaner (unless you prefer migraines). A little goes a long way and seems very effective, especially with some brass brush assistance on the varnish buildup.

If gasket wasn't fitted then I wouldn't fit one. Might be to let air in / out. When wading the gasket at the top will trap air in. Lack of gasket at the bottom might let moisture out.
