So I was checking to see if the car repair shop I took my car to to have the timing belt replaced and timing re-done had done what I asked and fixed my sprocket adjustment and set the camshafts back to 0 degrees. Turns out to my delight they had, however when I was tightening down the bolts that hold the camshaft sprocket back on I broke off one of the bolts. Attributing the minor slip of the wrench to the torque wrench telling me I had reached 15 ft-lbs i carried on and tried to rotate the engine using the crankshaft. It turned easier than before (when aligning the timing marks on the cover and got stuck and would not rotate all the way around. So my question is, I have messed up the timing right? how badly? and is this an easy fix for a car repair shop? ps, the car ran fine before I broke it and I have not started it since, im dumb but not that dumb. Thanks

Got any pics?

What you are describing doesn't make any sense as far as locking the motor - it requires more than a few degrees of movement to cause valve/piston contact.

I don't quite understand what you were doing - if they set the cams are desired, why did you loosen the gears?

Pics of the gears @ the Volvo markers (with crank marker set) would be helpful.

sorry for the poor wording, I posted this in the heat of the moment. I have actually contacted a volvo mechanic and he has told me what to do to fix it ( as far as renting the kit and how to re-time the car). Basically what happened is i broke one of the bolts that holds the intake cam to its sprocket.

I was probably just nervous and worried and saw a problem that was not there when i was talking about the crank not turning. Although i will obviously check after the timing job and before starting the car.

I was loosening the gears to check with my IPD cam adjustment tool to see if the garage had done what i requested in addition to the timing job because i still get multiple, what feel like backfires, at WOT and i thought misaligned cams might be the cause.

The only question I still have is where can i find a replacement bolt for the one that holds the sprocket to the cam? To try to help you visualize if im still being ambiguous, it is one of the three bolts that holds the intake camshaft to its sprocket (see pic). Thanks!


ps thats not my car but i will take a photo later today with my cams and their markings in relation to the alignment slots.

Get a new bolt from Volvo, it needs to be grade 8.8, with the built in flange.

I knew what bolt you meant, I just didn't understand why you were messing with it, you have clarified that.

Because im a fool. Thanks and this is the correct bolt right?

No, the camshaft bolts are only M6 or M7, shouldn't be that much

you need # 982778 (968159 old number)
