TIFU, please help.

I'm doing the timing chain. It's been a bear. The torque spec is like 30lb + 180 degrees. I am not a smart man. I was in the zone. I had finally figured out how to get leverage on this freaking bolt. I got carried away and accidentally torqued it to like 210ish degrees. I didn't feel it break or yield more than it did before. Nothing made me stop other than just realizing that was one too many.

Am I screwed?

 

I think you will be fine, but you can always just replace the bolt. They aren't that expensive.

 

I also just went to rotate the engine to check the timing and the chain jumped a few teeth because the tensioner wasn't in.

Did I bend the valves?

I don't know why it happened this time because I did it after installing some other parts while the tensioner was out and it didn't jump.

 

 

I used a Proto digital torque angle meter when I installed my crankshaft timing gear bolt. It reports the final toque after you hit 180 degrees. My final torque was 125 ft lbs. What did you use to hold the crankshaft while torquing the bolt?

 

I used an analog angle gauge. It absolutely sucked and did not work for me. I ended up just marking the bolt and sprocket and measuring the degrees as I went. I used a combo of having someone stand on the brake pedal in 5th and I kept the crank locking pin in place while I tightened the crank down.

I had not torqued down the cams yet when they slipped, so those bolts should be fine still. I'll reinstall the crank locking pin and cam locking tool and that should get me back in time as long as the cams are TDC with the markings on top, correct? I also used the skewers in the cylinder method to visually confirm the pistons position.

 

Sounds like you are ok. Reinstall the crank and cam locking tools. Correct! The writing on the cams should face up. Then you have to install the tensioner tool. I think it's 5-6 inch pounds. Then you tighten the Vanos sprockets. I torqued mine to 66 ft lbs. That's the max for those bolts, and was greater than the xxx ft lbs + 180 degree method. When I tried the torque + 180 method, my timing slipped. After you torque everything, remove the tensioner tool, and install a new tensioner and torque it down.

Remember these three sprockets aren't keyed like many cam and crank sprockets. It's the tension on the bolts that keep them from spinning on the shaft. Personally, I'm not a big fan of this design!
