Mechanical Timing Off

[b-morr]

Question >>> If the crankshaft moved so that the pulley notch moved up 10 degrees advanced, could you use the adjustable cam gears to line everything up again? (Balance shafts removed)


Why I'm asking (if you want to know) >>> I had some people help me put my clutch and transmission in. When putting the flywheel on, we just had something between the cam gears to keep the rotating assembly from moving (later did something else to make sure everything was torqued). While doing this we thought the torque wrench gave to show it was torqued, but it gave harder than the others. We realigned the cam gears to make sure they were in line, but forgot to check the crankshaft pulley notch...

After driving the car, not really hard, but noticing around 3.5k rpms the car pulls timing. I re-did the ignition timing, but I had to retard the CAS all the way to get to 0 BTDC.. After looking at some stuff, and putting a screw driver in the number 1 cylinder spark plug hole, I found out that the crankshaft had moved 10 degrees advanced. No belt damage, and the proper tension on it. That's when I remembered the flywheel thing and it all made sense.

So pertaining to my question, would that work? I know it would line up (already tested it, but haven't started the car like that), but is that a big NO NO?

I dont understand how doing a clutch/tranny install could effect the angle of the crank as opposed to the cams.. Unless your saying that when you had whatever you did holding the cam gears together and were torquing the flywheel down, that maybe it jumped time then? But as far as your question goes, I dont see why that wouldnt work but I would NOT recommend it! Just take the time to redo your timing and save yourself the headache of bending some valves. At the least!

Redo your timing belt and do it properly. Adjustable cam gears only turn the cam stick x* to make the valves open/closed exactly when they should be in relation to true TDC.

I can get everything in time with the adjustable cam gears, they can only move x*, and I'm still in that amount getting it all timed.

Well, then why are you asking if you just want to do that anyway?.....

Why on earth would you jam something in between your cam gears to tighten a flywheel down... Sounds like you need new helpers...

The proper way would have been to use an air impact or easier use a half inch drive ratchet with a 17mm socket on the crank bolt on the other side of the engine.

I'm extremely busy for the next few weeks and absolutely need the car, today I was able to get a ride to work, but tomorrow I wont. I'm just trying to find out it that will work the way I'm thinking to be a temporary fix.

When adjusting the cam gears, your moving the cams to open/close the valves when you want them too. So if the pistons are 10degrees ahead of the cams, moving the cams 10 degrees ahead would get them in time with each other right?

After adjusting the cam gears, both cam pins point up at 12 o'clock when the crank pulley notch is at 0 degrees (the "T" mark), and I made two new marks on the cam gears to make sure they end up in the same place every time I rotate everything, and it all goes to the same place every time. So all I'm looking for is will that work for the time being.

I'll be home around 2-3am and have to wake up at 6 and go back out to work, so redoing the timing isn't an option. I'll be on that schedule for the next 10 days straight, and am going to need the car.
