Hi all
Been a member for just a couple of month and this will be my 1st post.
Car was towed in by the AA with timing belt failure.
Stripped it down to find all exhaust valves bent and all exhaust rockers broken. So we fitted 16 new valves and 8 new rockers.
Built car back up having fitted new
Timing belt kit
Water pump
Head gasket
Head bolts
Gaskets
16 valves
8 rockers
On starting car after job completed car smokes badly and does not run properly. Smoke is black from incomplete combustion.
Our first thought was timing was a tooth out.
So wee stripped down to find timing is perfect ( we used vauxhall timing tools and clock dial gauge)
The car has no fault codes
Things we have tried
Swapping with a good running donor car.
4 injectors
Air flow sensor
Air pressure sensor in manifold
Egr valve
Compressions are all even at 30 bar
Disconnect exhaust
Turbo pressure is good
All reading in live data are good.
Called in our auto spark who has tech
2 and still no fault codes in Ecu. He also can't find problem.
Advised wrongly by main dealer master tech who thought that cam lobs on camshafts might have moved.
Camshafts are perfect and camshaft and lobs are the same piece of metal.
Reading live data from our donor car
The only difference is
Injection quantity is 4 mm
And our problem car reading is 16mm cubed.
Bosch say it should be between 5 and 8 at idle.
We don't know if our reading is higher because the car is not running properly or could this be our problem.
Hoping someone out there could help
Thanks
