I'm throwing this on here just in case you need it as i typed it out for some one esle and you may need it so why type it again.
Earlier in this topic I said i didn't know how to check the timing. I do in fact know how to check the timing, the reason i wrote i didn't is because i was getting my forums mixed up and thought i was on TRS for a minute.
On there I have made it known that the factory timing marks on my truck are wrong, but just realized that there is no way you could know that as this is a different forum.
Any way to check the timing, assuming your marks are correct, follow these steps.
1. Pull the top rubber plug out of the timing belt cover.
2. Locate the timing mark on your main drive pulley (harmonic balancer) and line it up with TDC on the timing meter located at the bottom of the timing belt cover.
3. Look in the Hole left by the removal of the rubber plug.
4. You should see a arrow made into the back of the plastic cover which is used to mark the timing.
5 the cam shaft pulley has a notch on it that is supposed to line up with that arrow.
If when you first look in there the notch is not there don't panic as the engine may be on the exhaust stroke making the mark 180 degrees off. just turn your main drive pulley (harmonic balancer) one more turn and then look.
If you still do not see it lining up that could mean your timing has slipped, or that the Balancer has sliped. You should look at the rear of the cam shaft pulley and see where the notch is, its real easy to see. Then line the notch up with the arrow inside the cover. Take a look at the timing ruler and if it says 10 degrees BTDC ur fine as that is where its actually supposed to be. If it says anything else and your having power problems you might want to get it checked by a mechanic.
Also a while back i paid for a timing diagram because i was so fed up with it and it said i could link it to friends so try clicking HERE
. If it doesnt show up and you want the info let me know and ill just copy the images off the page and put them on here.
