hey has anyone here done the intake cam sproket install on the s14 black top?

im gonna do mine and want to make sure im not overlookin anything.. I have the fsm but it gives me a bunch of extra steps...

so far just by lookin at the engine from the top of my mind i got :

remove batt. neg

remove valve cover

set to tdc on cyl # 1

mark the chain and cams

loosen the tensioner

move chain over

remove cam caps in correct order

remove cam

swap sproket

lube mains

install cam

install caps in order then torque

move chain back

tighten tensioner

put on all the cover shit back on and cool done right...

I would do this shit on the hummer h3s all day a couple of years ago but that was a couple of years ago lol

I would like to ellaborate with some one whos done this before thnx ^^ should only take like 2 hrs at the most I hope lol

Follow the FSM, it's really not that hard, it's not brain surgery. I've done it, but I'm too lazy to add anything to what you've said above at the moment.

You can remove the cam sprocket without removing the cam. You will need a 1" box end wrench to keep the cam from spinning. It has a hex on it right behind the gear. Before completely removing the center bolt, make sure the nvcs gear is still in one piece and not popped apart (parts may fall out if it has come apart).

ok so all i do is remove the valve cover, set to tdc, mark the cams, loosen the tensioner. and move the chain aside? and i should be able to take the sproket out without remvin the cam.. correct?

yup just hold the cam with i believe its a 27mm open end wrench and zapp the 24 mm bolt on the sprocket with and impact and it should come rite off

If the timing chain already has the grey and gold mating links, you really should take the extra 5 minutes to turn the crank until they line up with the cam mating marks at BDTC.

When it comes time to put the chain back on, it's easy for one of the two cams to rotate and skip a link, so it's a GREAT visual aid and help to have the colored links in the right places....that way you CAN'T go wrong.

I used a bungy cord connected to a hole in the hood to hold the chain up the whole time I did this, just to be safe.

MAKE SURE you follow torque specs on the cam caps.....I was lucking enough to have a friend lend me his inch-lb torque wrench....

Sup man happen to have changed out my VCT cam sprocket like 2 weeks ago, and I have to say that it wasn't as bad as I thought it would be when I first knew I had to change it out.

The whole process was like 2hrs at the most and one thing that could prove helpful to you that made my life a bit easier is that I left the tranny in 5th gear and that prevents the engine from turnning when trying to break that dam cam bolt loose.

It was a bi$%h to get loose but that helped alot, as far as any helpful write-up's I highly recommend you to check out the frsport.com writeup they did for S13 cam install.

It's basically the same dam thing and they provide pics so it helps a lot, good luck man and let us know how it went.
