Hey guys, I have this D16z6 I'm rebuilding, Just got the head back from the machine shop. 3 new valves were put in , I'm trying to set my head to tdc but the camshaft won't just stay at the designated TDC Marks(head-deck level/rear timing cover marks, "up" ). . I tried loosening all my valve lash adjustment bolts to the loosest setting and still nothing. Normally on a b series LS/b20s I would go and lock the cams with a punch, but I'm at a lost and don't want to do serious damage to a fresh head. Serious advice and insight appreciated. Thanks in advance guys.

 

I don't know if it's possible to do but I've always had trouble getting the rockers to sit the right way all at once. Make sure that they weren't tightened down with them upside down (facing the wrong way) .

As i said i don't know that it's possible to do . But it's all i can think of. I'm taking about the vtec rockers of course

 

I have done this before. I had a similar situation like this before on my B18. My cams didn't have the option to lock it in TDC. I haven't dealt with a D-series in awhile but this should give you an idea how how you can do yours.

Try this if you would like....This will be a 2 man job.

Bolt the cam caps down to spec. Have someone take a wrench and place it on the bolt that holds the cam gear to the cam. Spin the cam and cam gear counter clock wise like the engine is supposed to rotate. Once the cam gear markings reach TDC then stop the wrench and hold it in place. Have the other guy slip the belt back on (making sure the the crank is also at TDC. This should do the trick. Be patient and make sure you don't have any spark plugs in as that can cause resistance while rotating the cam and the cam gear. Check timing and then reassemble.

 

You're using the wrong timing marks on the cam gear to mark TDC. For the z6 line it up with the 7 o'clock line.
