Default HELP HELP HELP! Botched timing belt.

So I'm pretty sure that I messed up when putting the new belt on. Put everything back together and have this huge shaking coming from the engine. Getting these codes.

16775 Camshaft Position Sensor (G301): Implausible Signaland
16750 Camshaft Position Sensor B Bank 1 (G300): Implausible Signal

I took those descriptions from some other posts (don't know why those codes aren't in the Bentley manual)

Seems like a timing issue, and here's the kicker... I did it with out the cam locks. I know, let me have it for trying something so stupid. I'll take all the criticism you've got AudiWorld.

But now what!?!?!? Please any help would be appreciated. Also, coolant started pouring out the bottom after start up which makes me think that I did something wrong with the water pump so I'm gonna start there and see what I get.

Please help!! Thanks so much.

This was the one I followed. Great write up and I can't figure out where I went wrong. Was incredibly deliberate counting teeth and marking up the old belt and the gears. Beating myself up over this now.

Stop. Go back. Start over. Counting teeth and marking stuff will NOT work. Use the correct procedure and lock the crank and use the correct tool on the cam sprockets. Throw your markers and chalk and finger nail polish in the trash. Good luck.

Exactly. If you follow PART of it, you have to follow ALL of it. The engine really cares where the cams are in relation to the crank, and it is nigh on impossible to mount up a belt without the cam holders at the very least. I've done it without locking the CRANK on a V6 and V8, but NEVER without locking the cams.

Ok guys. Found a mechanic willing to lend me the cam locks for $50 down the street. Am motivated to get this done CORRECTLY today.

My only question is how do I get everything to TDC again. The cams have moved as well as possibly the crank. What next?

Why would you rent the tool for $50 when you can own it for $115?

Because I can't afford to wait 5-7 days for the item to ship here.

Ok. So I have the cam locks now. I just hope I'm not too late to get it all lined back up. If I get the locks on and my crankshaft is TDC according to the mark on the lower timing belt cover, am I back on track? I'm going to have to turn the camshafts by hand from the gears, which is not easy but if I get them all back to original spots and the locks fit on am I ok?

Feeling very lost right now. Def should have started with these locks but just didn't have the money to purchase or rent ($500 deposit from blauparts) initially. In desperate need of some assistance. Thanks in advance.

Cam locks are on. Timing seems to be set. Only question now is if the crankshaft is absolutely right. How can I tell if I set the crankshaft?

Is the little arrow on the lower pulley cover lined up with the mark on the pulley? If so you should be good to go.

So all the timing is back. Thank god. Only issue now is my water pump keeps leaking. Every time I put more coolant in and start the car, coolant starts pouring out the bottom. Any suggestions?

yeah take it all off and start over

you didnt get the pump seated properly ..

a little drop or two is normal out of the bleed hole on a new pump
if its pouring out you need to find out where and why.

you should have addressed this before setting the timing again .. the pump is behind the timing belt..

look at the bright sde .. you will be really good at this when you are done .. also make sure you got the thermostat and housing seated properly.

Be sure your doing the thermostat also. Its only accessible when the timing belt is off. Only way i see coolant just dumping out of the pump is if you didnt get the gasket on right or its not tightened down all the way.

Thermostat can be accessed at any time on 3.0. fix water pump set belt and dont forget to rest variable timing with special socket.

Thanks to all for the help. My stress level has gone down considerably since I found a car to borrow for a couple days. Here's a update of where I'm at...

Got the water pump seated correctly now. No more leaking but my timing is still off.

I rented the cam locks from a mechanic down the street for the day and had to return them so I'm at a standstill right now. I have a friend who is coming to help me this weekend. He thinks he knows where I went wrong just from talking to him but now I need to try and rent these locks from the mechanic again.

At this point I wish I could just buy them but I can't seem to find any retailers. Only shipping and that takes 5-7 days. Don't feel like waiting that long, plus my friend is coming tomorrow to patch up my handy work.

go ask your mechanic if you can borrow them again on Sunday as he should be closed.
