Put the car back together after noticing the exhaust cam was a bit off.
But the same code came back immediately. P1554
So the exhaust cam is probably unaligned again...
I’m putting the splines in the first available slot rotating and using the alignment bridge but the exhaust cam keeps getting unaligned?
I even rotate the assembly by hand a couple of rotations and the cams are fine before assembling the valve cover. But the minute I turn the car on the code comes back and my cam is off.
I must be missing something.
Do the pistons need to be fully inserted into the vanos before rotating the splines into the cams? Or vice versa?
I don’t understand why the intake cam seems fine though if I’m doing it wrong.
Any more advice?
Thanks!
