hi guys , im new to this , but i have a question regarding my volvo, i just bought a S70 and found out it needed a head gasket, so i decided to replace it , after all i am a tech and been a tech for years , but i have to admit i have little knowledge about volvo until now. Im having trouble lining up the cams with the marks on the upper timing cover, i know my mistake already , i didnt set the engine to TDC before removing the head, (but set it to TDC while it was apart), i set the intake cam , im having trouble with the exhaust cam, , does anyone know how to do this?

As rule 308 stated you now need the cam shaft setting tool to get the cam alignment, and to get the correct crank alignment, there is a tool that installs (I think, by the starter motor), that inserts a pin into the flywheel to hold things in proper alignment. I can't comment if that is a true TDC, or if this is just how Volvo does it.

Here was a link I found that MIGHT??? help, but they want money to see the answer, so who knows if it would be helpful.

Here is yet another that gives the process of doing cam maintenaince using the tooling. It might give you some idea.

Here is a link to e-bay for the tooling, but not sure it will work on a VVT engine, but it does have a crank locator in the set.

Yeah, you kind of screwed the pooch on this one. The correct way to do it is to install the factory tool that holds the cams in align as you drop the cam cover with the cams onto the top of the cylinder head, use the correct tools to pull it down into place and then bolt it all together. If you have installed the cam carrier with the cams already and the cam shaft is not in the correct place you will have to remove the cam cover and get it in the correct position before you reinstall it and hope that you did not bend any valves in you previous install.

If you look at the rear of the cams you will see that there is a slot ground in them. The proper tool aligns those slots so that they are inline, as in flat like you could place something in there that would lock them together. Look at the front of the cams and pay attention to the 3 bolt pattern that the cam gears bolt into. When you have it set up properly the slot in the back will be inline and the triangular bolt pattern will have one triangle pointing straight up and one pointing straight down. Truthfully, I forget which one goes up and which one goes down, if you say that you know how the intake goes in, then the bolt pattern for the exhaust will be opposite of it.

You said that you set he crank up at TDC. I hope that you mean that you align the timing marks for the crank, these engines do not assemble on TDC, when the marks are aligned it is about 30 degrees of crankshaft rotation off of TDC and if you spin the crank around until the number 1 piston is at the top of it's stroke regardless of the timing marks and then go ahead and assemble it you will surely bend valves.

Welcome to the world of Volvos, if you have any questions feel free to e-mail me or just give me a call at the shop on Monday.

So in order to do this job correctly one would need the cam locking tool and what else? I have access to these tools but this will also be my first white block head gasket replacement. Mine is a '95 850 turbo with oil in the coolant only.

Thanks,

It is easier to set the alignment marks prior to the removal of the cylinder head and cam removals. Keep in mind that when the camshaft alignment marks match the "V" marks on the top cover of the belt, the engine is not at TDC. It's actually slightly off of TDC.

You can certainly reset the marks afterward, however, make sure you properly align the crankshaft mark, and then align the cam marks and place the belt over the crankshaft working in a counter clockwise direction. It's difficult with the S70/V70 and 850s as there is only about 1" to maneuver. After you have the belt in-place, release the tensioning unit and spin the assembly 1 to 2 times. This way you'll be able to re-check all alignment marks and also tension the belt.

As you turn the crankshaft CCW you'll be able to feel the compression if spark plugs are in-place. I believe you'll need a 30mm sprocket and a medium breaker bar.

Good luck!
