Hi,
it takes me 4 full days (nearly 8 hours per day), but the engine run yesterday at around 19:00 again.
in sequence:
First i have change the original engine bearing (behind the engine) with a special built one, which use a control arm bearing from a Audi A8.
Because the inner diameter was a bit larger than the original one, i make a bush, even when the force will be tranferred due to friction and not due to the bolt.
Anyway, here are the pictures which shows both bearings, the new one should be much stiffer:
As next step, i have modified the ventilation plate, to fit with the new Spal fan:
It took me a long time to fit the flange adapter and the wastegate flanges, by the way the exhaust manifold gets a hole for EGT measurement:
Here how all together should look:
After i cleaned the engine block, i have also cleaned the piston surface and have to notice, that there was some contact between the piston and the valve with the old arrangement.
Than i have measured the gap between the old headgasket and the pistons (1,0 mm) and also the distance between the valve and the cylinderhead (spilt surface) (IV 2,4 mm; EV 2,1 mm) to calculate the distance between the valves and the pistons in OT (TC?) (IV 3,4 mm; EV 3,1 mm). I have also measured the max. lift of the valves due to the springs or the spring caps with 11 mm, which is not really much by a valve lift of 9,9 mm.
After the cylinderhead was put in place again, it was high noon, will the turbo fit behind (under) the fire wall?
first check (after allready change the way of some cables and dismount the heat protection):
Seems as could be done, so i bent the heat shield and mount it with two new distance spacer:
and HERE IT IS:
quite a tight fitting with the compressor housing:
The next problem to solve was the oil pipes:
Step one
Step two
Step three
making the last gasket for cooling water connector:
And put it all together an start the engine:
Unfortunately i missed to make a picture from below. Up to now the only problem which must still be solved is
the downpipe with the conection for the wastegate pipe. to be honest i don't have just a idea how to start
that, but comes time, comes solutions.
Best Regards
