I think I fucked up.
Step 1: So I've set the crank pulley timing mark to the 8 o clock mark on the oil pump, removed the RH (drivers side) chain and tensioners. Locked the cams with the alignment tool and set the crank pulley mark to the 5 o clock position by hand cranking clockwise.
Step 2: Removed the primary chain, tensioner and RH idler gear. Replaced the oil pump. Removed the LH side chain, tensioners, and idler gear. Realised the LH side timing marks aren't at the top, so I decided to put every everything back for Step 2 except putting new guides, new gears and reusing the old tensioners.
Now the crank is locked up within probably 60-70 degrees. Clockwise or anticlockwise. At this point I was lost and thought maybe the alignment tool might be locking everything up so I decided to retrace everything to step 1. Now everything is back on, crank still locked.
I'm thinking either something fell in the intake, or it's completely out of time and locked up.
Do I try and pull the heads?
Edit: I have an SIDI engine, not alloytec.
Edit 2: from memory RH and LH side looked like it was like 3 to 4 teeth in front of the marks before but tight. And primary chain was loose.
