Hello all, I just had a question but I can't seem to find a straight reliable answer to online anywhere. Alot of misinformation out there. Now about 90% of what I see are people saying that that stock timing is set at the point where cylinder 1 is at TDC on the compression stroke. But I have also seen numerous other things that say it's actually when cylinder 1 is at TDC on the exhaust stroke (valve overlap phase) meaning cylinder 4 would be at TDC compression. I just performed a timing job replacing all timing components aside from the water pump. My main black intake side guide broke into about 6 pieces when the top bolt backed out, the chain also shaved two other bolts down pretty significantly. I still don't know how I never got any chain noise with it slapping against bolts like that, ANYWAY thats a story for another day. Now before I removed any timing components I rotated the engine by hand until my Cam Phaser timing marks were at the recommended 10 o clock and 2 o clock positions with the crank keyway at the 12 o clock position. Everything I have read or seen has said that that is the correct orientation to set stock timing. So at that point I removed everything. Started with the balance shaft set, aligned everything with their respective timing marks and after it was all installed I rotated it by hand 2 full revolutions and all the timing marks came back to where they started so I moved on to the main chain. Got everything reinstalled, unique colored link matches up on the intake phaser at 2:00, the first blue link lines up with the exhaust phaser timing mark at 10:00 and then the 3rd Blue Link lines up with the crankshaft sprocket timing mark at 5 o clock. Torqued everything down and rotated the engine again by hand 2 full revolutions. All 3 timing marks returned to where they started with no hard stops or binding during rotation. So that SHOULD HAVE verified that it is timed properly, from my understanding. But with all that being said, my cylinder 1 is definitely at TDC exhaust and NOT TDC compression. If I would have turned it another 360° from where it is to put cylinder 1 at top dead center compression than my phaser timing marks would have been at like 4:00 and 8:00, which is obviously not correct. Am I overthinking it and psyching myself out or am I missing something? Although I'm not a beginner with a wrench by any mean, This is the first timing job I've ever done. I have pictures attatched to verify location of all timing marks before just I rotated it. Any advice would be much appreciated
