I've spent hours trying to set the timing on my d16a6. It has a milled head (do not know the exact spec's). All parts are stock. After installing the timing belt, I set the cam gear to TDC, and then the crank to TDC. However, when I install and tension the belt, timing is thrown off what appears to be 4-6 degrees (advanced).

My last best guess is that the milled head is throwing off the timing. First, is that most likely the problem, and if so, what do I need to do to get timing set properly?

 

When a head is milled the cam are closer to the crank, therefore, the timing will be retarded. To resolve this problem, you would have remove the head the mic it for thickness. If the thickness is below minum, a slim can be use. However, I would recommend a machine shop to perform the work.

 

Definately find out how much the head was decked... thats priority #1

My head on my h22 was milled 4 thousands and my timing marks aren't off. So, unless they milled your head down more than they should have I don't think thats the problem.

 

My head is milled a lot more than that. The timing marks are off a very little bit. You are probably installing it off a tooth or are not reading the marks correctly. It should line up very close to stock.

 

move it one teeth either way depending on your timing to set it correctly,

You can correct it by using a thicker hg

 

Milling will retard your cam timing, like said above. Do not adjust by moving a tooth over. You need to adjust by using an adjustable cam gear. It will move your timing marks off slightly, but not by a complete tooth.
