so I have a 91 ka24de. I was told that when I set the engine to TDC (top dead center) the cams would point away from each other at 180 degrees… basically flat… but I was checking mine… and they never seem to point at 180 degrees… they do point away… but slightly facing up. about 5-10 degrees… I had that stupid timing guide noise… I took out the timing guides… one which was broken in half… loosened the top tensioner… my question is… could my timing have jumped off a bit for one of the cams? because my engine shakes alot at idle… and the fact that they aren’t facing away at 180 degrees at TDC… ty ed ---

What’s up ED the chain and the gears should be marked, I had to pretty much had to remove the head on my ka a while back, i order to get the right timing , I kept rotating the crank till all the gear/ chain marking were lined up. Use the chain as a reference,
