Where are the cam marks on the exhaust and intake cams. The intake cam has a mark "l" on the front side of the gear. The exhaust has a mark "l" on the back side. Both cams have a "M" on them. I have replace the belt using the "l"
and it runs rough, missing on cylinder 4. Volvo dealer will not help. Any advice?

Here's the response I got...

If the mark alignment was wrong the problem would be more then cyl 4. Cyl # 4 could have bent valve. Why was the timing belt changed & was the car running rough before?

1999 2.4L head bolt torque, 15# 44# then 130 degrees

I am re-installing the head and found that the torque is 15, 44, then 103 degrees. I do not know what the 130 Degrees means.

Can any one help?

I finally got the head back on and now need a vacuum hoe diagram.
I didn't mark the hoses. Thought my memory would suffice. Does anyone know where I can get a vacuum diagram for a 1999 V70 AWD turbo 2.4?

vacuum diagram

I found it but it shows the red hose going to the pressure regulator from the TCV. I have a hose coded with a red dot that goes somewhere. I cannot figure it out from the diagram.

Also, thanks SULLEY007 for all the hard work and time you put into this forum.

The hose with the red dot.....where does it come from? Or, is it totally removed at both ends? Is there a vacuum fitting on the pressure regulator that is left naked currently?

where is the pressure regulator?

The diagram under the hood shows that the hose (red on the diagram, and coded with a red dot where it attaches to the TCV switch, at least I believe it is a TCV switch) goes from the TCV to the pressure regulator. I can't find the pressure regulator. The diagram shows it along the passenger side firewall. Not there.

turbo pressure regulator is located on the turbo pretty sure its on the top. lay over the top of the motor and look down on the drivers(left) side of the turbo it should be sitting right there next to the block. as for the timing marks the intake and exhaust cams are marked with a dimple on the FACE of the pulley, look at them from the right(passenger) side. the crank gear is slightly different. it has 2 marks on consecutive teeth. the mark is in between the marks. best bet would be to remove the crank pulley for the serpentine belt(4 bolts and a big 31 or 32 mm nut) so you can see the marks better. you should have reinstalled the coil cover/timing gear cover on the topside bc this is where you line up your cam marks.

runs rough like the timing is slightly off, marks line up

The vacuum hose went to the turbo, Thanks for the help. The engine is all back together and started. No leaks. It runs rough. ETC light is on. It runs like an engine that needs the distributor slightly adjusted. You know, the old way we adjusted timing. Any suggestions.
