Ignition Timing

[Nigelbs1]

Had to have offside manifold welded again, after manifold was refitted the car is pinking all over the place under load, 3rd gear at 2500rpm and i loose all 8 cylinders back off the power and she comes back to life. Connected up laptop Ignition advance is at 50 degrees under load at 3000 rpm. Whats the maximum the igntion advance should go up to and is the TDC sensor near the manifold if so i recon i've damaged the sensor or its moved, ecu doesnt report a fault with the sensor or wiring though. Or could it be a fuel pressure issue?

Crankshaft sensor may be?
