Effects of Wrong Cam Timing

[s13satch]

About 2 years ago I replace my timing chains in my '91 240sx. I used the guides from All-Data and Jim Wolf to make sure my timing was correct. I was sure that I did it right, but yesterday when I was replacing my valve cover gaskets I decided to look at the timing marks again. The reason I did this is because my compression is at 150 psi for each cylinder. I have no drivability issues and don't burn oil. With that in mind and the fact that all the cylinders are equally low, I thought maybe my cam timing was off.

While I didn't have access to a computer yesterday, I did take a mental pic of the timing marks. Today I reference that "pic" with the one from Jim Wolf. I think I may be 1 tooth farther off than I should be. Generally speaking, this would open the intake valve a few degrees later and could possibly lower compression.

Anyone know what effect this has on the KA24DE?

This is the kicker - my motor (to my knowledge) had not been previously worked on in a manner that would require the removal of the cam gears. Yet, my compression was at 150 psi BEFORE I replaced the timing chains. So, the car may have been 1 tooth off from the factory as well.

a few degrees meaning just shy of 19 degrees off. a car with a cam 19 degrees off wouldnt be running too well at all.

its entirely possibly your car just hsa some crappy compression

That's what I figured. I'm just trying to explore all possibilities for my compression. I really need to take the time and have a leak-down test done.
