Timing on 99 S70 non-Turbo

Removed PDF.

Just FYI, I don't think that pdf is completely relevant, I think it only shows the timing marks for the VVT engine. OP's is clearly not VVT, I am expecting it to have a top cover with the offset notches. General procedure is of course the same, but which marks you use is of critical importance.

Can anyone verify about which timing marks to use?

His 99 should be just like my 98, or any 850. There's one mark on each camshaft sprocket that will line up with the notches on the timing belt cover.

The only difference may be the marks on the crankshaft, which can sometimes be a real PITA to see or read correctly..

OK, I thought so. As I understand it (and the pdf shows) the marks for VVT engines are straight up, at 12 o'clock, not offset like the 850 or 98 x70. So OP needs to keep that in mind, not use those notches that you can see in his photo.

Maybe I posted the link to wrong PDF. It was for B5244S. I removed it just in case. I don't want to be responsible for someones engine damage.

B5244s was a split year. Some got VVT, some didn't.

They changed some things mid-98 too. Silly Volvo engineers.

Basically, we want to do a couple of things.

Can somebody please verify, or explain how I can verify, if I have VVT?
1. Can you identify based on the picture I've provided?
2.If it is VVT, where can I find the timing procedure process to time this? I think I know if it's non-VVT how to time it, if it's non-VVT, is it just a matter of lining up the two cams with the cover and the crankshaft at the same time?
3. If it is VVT, how does this procedure differ?

You do not have VVT. Just line up all of the marks.

Thanks for the quick reply. Since the crank sprocket is half the size in diameter of the cam sprocket I can turn the crank twice and get the cams in two different positions. Although I realize all three need to line up, I believe (since I jumped some teeth) I will need to start from scratch. In other words I can't just line all three up I need to make sure a particular piston is at tdc.....I need these procedures to make sure I'm doing it correctly. Is there a post or does anyone know the full procedure from scatch?

thanks I really appreciate all the help from everyone.

For info on setting timing, you can either read the head gasket replacement instructions or the timing belt instructions. You should be fully comfortable with the timing belt job procedures going into this, but the steps are very straightforward:

1. Set the crank on the mark.
2. Remove the timing belt.
3. It is now safe to rotate the cams as much as you want. Put them where they belong.
4. Zip it up.

Step one sets the engine so that piston #1 is just before TDC, and the other four pistons are out of the way of the valves. Hence you can do step three.
