I just got put my head back on after a headgasket failure and when I am trying to install the cams they wont at up or dtc I checked my crank and its a dtc but my intake side cam wont stay in the position. I uploaded a video to show what I mean and sorry for the crap video but you can see what I mean. Any help is appreciated



I did search and stumbled across this thread http://www.clubintegra.com/board/showthread.php?t=63959 it seems hes having the same problem as me but I also tryed putting in the cams then installed the caps but I couldnt move the cam/camgears to the up position

The valvesprings are pushing on the cams. OFC they won't stay in place until everything is bolted down...

You just need to install the cam caps, rotate the cams into position, and install your timing belt. Double check your cam timing before and after you tension the belt.

I did install the cam caps but the cams wont rotate

TheRealTegger

In your first post, you said the cams won't stay where you want them because they keep moving on you.

In your second post you say you can't make them move.

So which is it?

He's say install the cam caps and tighten them down. On the video there on but not bolted down.

sometimes i had to put wrenches on the cam gears, move in back or forth a little, put the belt on. make sure everything is lined up then tighten the tensioner down.

Ok, set your crankshaft to top dead center, then turn it off a little (say an inch to be safe) in one direction or the other(clockwise or counter-clockwise, doesn't matter at this point).

So, now your crankshaft is an inch or so off from TDC. Bolt your cams in completely and don't worry about setting them perfectly yet. Just put them in how they want to lay(which should be reasonably close to TDC) and bolt them in. They will be off, this is why we set the crankshaft off of TDC by an inch so that when you bolt in and set your cams they don't push a valve onto the top of a piston and bend it...

Now, your cams are totally bolted in and they are not aligned correctly and your crankshaft is not set to TDC either. Put a ratchet on the bolt attaching the camgear to the camshaft and set the camshaft where it needs to be by turning it. Do the same for the other camshaft. You will need to put some force into it because you are turning the cam against the force of the valve springs.

Ok, now the dash marks or what ever you want to call them on your cam gears are algined and the up arrows are pointed in an upward direction. Now, set your crankshaft back to TDC. Everything is now aligned. Proceed with putting the timing belt on from the bottom up. You will probably have to tweak the camshafts a bit to get the timing belt to fit over them perfectly when your trying to get the timing belt to slide over the cam gears. That will explain itself better when you get to it. Good luck.

You're just not turning hard enough. Get your wrench on the cam gear bolt and give it some good (clockwise ONLY) twist. Be careful not to over-rotate.

1998GsRIntegra

Why clockwise only? Just curious...

I don't follow that because everything is opperating individually at that point, and the crank is offset so the shortest direction of rotation for the cam to get to TDC would be the best. Or no? Our motors (B-Series) also rotate counter-clockwise so...help me out with your logic.

whole engine is designed to move counterclockwise

So that you don't loosen the cam gear bolts when you try to turn the cams.

i dunno why you guys are making it that complex. it aint that difficult. just have a little finesse. with the belt on the crank gear and aligned at tdc, slip the belt on the exhaust cam gear while holding it in place. then, while holding the exhaust cam gear in place, slip it over the intake cam gear while holding it in place. just hold onto the belt to keep it all aligned.
main thing is you wanna start at the crank, then exhaust, then intake. this leaves the slack on the intake side to be taken up by the tensioner.
it may take a couple tries, but you'll get it.
don't know why people are unbolting things to do this.

No need to unbolt anything. OP just needs to replace the cam caps, position the crank and cams, and put on the TB.

OP whatever you do do not rotate the cams all the way around. Keep them as close as possible to TDC when the crank is also at TDC.

el crapitan

ok. sorry, i misread that

MurtazaDSM

ok cool thanks guys I completely forgot about the bolts that hold the cam gears I was trying to turn it by hand haha

Dogginator

Loosening the valve tappet adjusters helps for rotating and positioning the camshafts.

ok I got everything in place and now its time to rotate the crank pulley but how will I rotate the crankpulley counter clockwise if I dont have the crank pulley bolt in there? If I try to put it on it wont be in tdc anymore and requires me to turn the motor clockwise or is it ok to put the bolt in and turn the motor clock wise then set it all back to tdc then go counterclock wise 5 turns. Im stuck on number 14

IIRC, I put the car in gear and pushed it, while my wife watched for TDC. You should probably do that before you bolt the cams down.

I may have already had the belt and pulley on at that point. You can actually install the cams under the timing belt without removing it completely.

el crapitan

just use the belt to turn the crank gear. without it attached to the cams, there isn't all that much resistance.

MurtazaDSM

can I just a impact to get the bolt on tight enough to not unthread itself

Easiest way to do it.

sebTeggy

lol @ the people saying 'just put the cams in and rotate them'. Do you guys know what TDC means? There is a piston there =.=
