Brad850 Posted July 5, 2013 Report Share Posted July 5, 2013 Picked up two na cams today and just realized they have no timing marks on them. I know that the dist and cam sensor ends are parallel when lined up correctly, but how will I know I'm not 180 degrees off? And with the engine in the car, it's impossible to get a good angle to make sure they are exactly parallel. Any tricks? Also does anyone have any definitive info regarding 93 cams being better than 94+? Might just head back to the junkyard this weekend and get cams from the 93 I saw and hope it has timing marks. Don't want to spend another 40 bucks though. Link to comment Share on other sites More sharing options...
survolvo Posted July 5, 2013 Report Share Posted July 5, 2013 There is a tool that you can use to line them up, or what I did was just cut a piece of metal stock down to fit inside the holes in the head/cam cover, and line them up with the seam.

survolvo Posted July 5, 2013 Report Share Posted July 5, 2013 Here is a pic of how they line up, notice they are staggered. Link to comment Share on other sites More sharing options...
Brad850 Posted July 5, 2013 Author Report Share Posted July 5, 2013 O I understand that now. So the 180 thing is easy. My only problem is...with the engine being in the car, I'm looking at those slots at an angle. I can't look at it dead on as if my engine was on a stand. Out of curiosity I recently set my current cams with the timing cover marks, removed my dist and cam sensor, and even though I knew they were parallel I couldn't be sure just from looking at it. Plus the engine sits at an angle which doesn't help. Link to comment Share on other sites More sharing options...
survolvo Posted July 5, 2013 Report Share Posted July 5, 2013 That is where the piece of metal comes in handy, you cut it so it fits in there and slide it in the slots and line it up with the seam on between the head and cam cover Link to comment Share on other sites More sharing options...
Brad850 Posted July 5, 2013 Author Report Share Posted July 5, 2013 Got it.. thanks man. I guess I can make my own marks later once I get them in and line them up. Link to comment Share on other sites More sharing options...
Simply Volvo Posted July 5, 2013 Report Share Posted July 5, 2013 Make sure the cam gears are in the middle of their slots as well so when you adjust timing you have a full 7 degrees in each direction. As long as the rear is lined up the cam gear position does not matter. Link to comment Share on other sites More sharing options...

Can't see any gaps under the 3 bolts like my turbo ones that I've already adjusted. All Volvo cams are adjustable right? I'm just more worried about getting the shaft itself straight Factory tool.... In use.... Could definitely make one of these. Would be cool if I could rent one for cheap though. Also just found out that the cams rcstdad dyno-ed with are 94, so hoping for 11 hp lol. Still wondering how much better the 93's are though. Probably not worth another 40 bucks. Link to comment Share on other sites More sharing options...

Brad850 Posted July 5, 2013 Author Report Share Posted July 5, 2013 Would definitely rather rent. Guy has 96 feedback, but his neg feedback looks to be from 2 idiots...hmmm. Might call the dealer see if I can rent from them. Thanks man. Link to comment Share on other sites More sharing options...
Simply Volvo Posted July 5, 2013 Report Share Posted July 5, 2013 You really don't need to use the tool. Just line up the slots with the grooves where the cover seals to the head parallel and you'll be fine. All gears are adjustable. Also if you're replacing the cam seals you need to take off the gears. Also I got the 93 cams as I heard they were better as well. My reasoning is that if the intake manifold was different in the 93 there is a good shot the cams are different too and in a good way.

Brad850 Posted July 6, 2013 Author Report Share Posted July 6, 2013 Think I'm going to change out the front seals once the cams are aligned and I mark the gears. Link to comment Share on other sites More sharing options...
Keaton85 Posted July 6, 2013 Report Share Posted July 6, 2013 The intake is above the line and the exhaust is below if you note the pictures. You do NOT need the tool as the cams will set the timing. - Make sure the crank is on the timing mark!!! - Put the cams in and align them with the head like pictured (does not have to be perfect) - Bolt the cover down - Install seals - Put the intake and exhaust cams on, aligning the timing marks in the general direction - Make sure the bolts are in the center of the slots on the cam gears - Put the timing belt cover on and move the cams to the correct marks Link to comment Share on other sites More sharing options...
D s50r Posted July 6, 2013 Report Share Posted July 6, 2013 thats one thing i would never attempt to do with a interference engine. even renting the tool for x amount of money is cheaper then a vlave job if u dont do something right. i do these weekely and i still use the right tool everytime, Link to comment Share on other sites More sharing options...
