Yeah they're excellent little things for just this sort of job.

Anyway, how's it coming? You checked those valve clearances yet? That's where my money's on at the moment & if you catch it before it's run too much you may even get to keep the affected valve & seat if it's only ally jammed in there.

One of those scopes would be a godsend if it is this, as you could use a flexi bar or screwdriver to loosen the bit of crap once you've found it & then put a screwdriver with blu-tak on the end down to fish it out, all by only removing at worst a manifold, the valve covers & plugs...

If it does come to pulling the head, there's NO need at all to drop the motor. Only thing that makes it tricky is if you have studs & nuts instead of bolts holding it down, even then you only need to take the rearmost studs out to do it in-situ. I've just pulled my head & the worst bit by far was accessing the turbo & oil feed bolts, you could even bypass this by undoing the 7 manifold nuts & tying the lot back a few mm, I think. One thing I will say though, if you're lifting the head on you're own then
1) remove the radiator so you can stand in the bay, or you'll break your back trying to lift it!
2) when you're ready to go lay a thick blanket over the nose of the car, then you can rest the head on this while you climb out.
3) ideally be in a garage, or at least a warm state of the US, it's no fun at all trying to strip an engine with freezing rain running down your neck!!!

You're getting close now, with the turbo off & inlet mani' out the way you're on plain sailing from here. Just make sure you undo the head bolts in 3 passes & in the correct order (opposite order to tightening sequence).. I'd say maybe an hour until the head's off now.

Oh, make sure the drain plug's out of the block too or water can get into the oil passages!

As to the oil, it's normal to have some oil in the intake but if you think it's excessive (only excessive if the car's visibly blue smoking IMO) then you might want to check the turbo oil drain isn't blocked with carbonised oil caused by shutting off without warming down. TSRM has specs for measuring turbo shaft play too.

Best of luck & let us see the carnage of the old HG when you're done!

EDIT-: Don't Black MA70's just look the dog's danglies compared to any other paint job? It's the ONLY colour for a big GT car like this IMO, and if I could respray mine the only thing I'd change is I'd go from Toyota's plain Black to BMW's "DiamantSchwartz-Metallik"

EDIT#2-: Re: Weather, YOU LUCKY BASTID YOU!!!! hahaha, hammering it down here...

no no no not the oil drain, the block coolant drain bolt (see the handbook p142 IIRC, or the tsrm) so that the remaining coolant in the block doesn't spill over into the oil passages & bores when you lift the head.

Oh & don't zip tie or fold the timing belt in any way as it can get damaged. There's no need to keep it on the teeth if you set the motor to TDC before you remove everything (again see the tsrm for locations of timing matchmarks, it's dead easy & failsafe for getting it back spot on, plus you'll probably want to turn the engine while the head's off so you can decoke all the pistons properly).

I'm gonna sing & do a rain dance for ya now! lol. Let's see if it really does have a metal HG..., maybe he meant "Moron-fitted Head Gasket" if it's gone already!!!

You don't HAVE to take the cam gears off to remove the head, but it's so easy I don't know why you wouldn't want to, just lock them together with an old screwdriver handle between them & undo the 14mm bolts, they pull right off, just make a note of which holes the dowels are in (usually the middle unless something's wierd)...

I did it just so I can paint the timing cover up nice & pretty!
