supra head gasket questions+ rebuild

Vacuum Solenoid Valve: part of the EGR unit (Exhaust Gas Recirculation) as it says on the label, it recirculates a percentage of the exhaust gas back into the inlet manifold. All to do with lowing exhaust emissions, some UK members have removed theirs, as you probably know vehicles registered before 1992 in the UK are allowed a higher Nitrogen Oxides emission levels that’s also why many remove their cats.
Back to your pipes, I would suggest you replace the ones that are difficult to get at and look inexpensive, there are a couple of small 90? elbows one on the exhaust side rear of the head and one at the front just behind the thermostat housing. How does that large turbo concertina pipe look ?, the one that fits to inlet side of the turbo with a few pipe coming off of it.

Andy, I marked up some hoses in red and blue in the pic`s in my earlier post. The blue hose which supramacist was referring to (“Lower block hose back behind those pesky starter bolts”) on early Supras was capped off with a rubber end cap, on later Supras this was redesigned so the pipe terminated with a metal end cap. The hoses marked in red are the 90? elbow hoses I was referred to in my earlier post.

Ya...., I just blew the coolant line coming from the water pump to the t-stat housing. Yeeehaw.

Luckily I have just replaced a different coolant line and I may be able to scavange a bit here without ordering a new line.

None the less I'll call monday and get a price and an eta if I order it.
