I tried today to adjust my timing cause of valve noise.I hooked up a timing light,ran engine to operating temp,jumped the plug at the kick panel,loosened dizzy,removed the rubber plug.Found the timing is way off moved the dizzy and it wouldnt move no more.Checked with timing light and is still off.If I take out the dizzy bolts I believe I can set the timing.But the dizzy bolts wont line up.Anyone have any suggestions on what is wrong.Could the timing belt be a few notches off?I checked he firing order and its correct.

Is it hooked up to the number 1 spark plug wire (driver side cylinder) ?

bdr_one

Yes double checked it

rockycat

Could it be you are still auto timing, jump not correct.

bdr_one

Dont know what you mean by auto timing

MAD_MIKE

If your jumper wire is not conducting the CEL will not be lit and the timing is still going to be adjusted by the ECU. Can usually tell if the jumper is working by watching the base timing, if it is steady the jumper is working, if it still jumps around the ECU still has control.
If the timing is stable and not adjusting but the timing is off recheck the camshaft timing belt adjustment, it is either not correctly timed or the tensioner on the timing belt has loosened and allowed slop/retarded timing.

If by "valve noise" you mean ping under load the first do as MAD MIKE posted and if all is good and base timing is ok and you still have ping then remember the computer does the timing so get better gas.

Ok I check it all again the timing wasn't jumping around it stayed in one spot I'm thinking the belt has slipped

MAD_MIKE

Check the big acorn nut on the timing cover. It should not be loose, if it is you have found your problem.

maybe mechanical timing is off

bdr_one

I dont see a alcorn nut been all over the timing cover.

Acorn nut should be below the motor mount coming through the timing cover on a 4cyl.

MAD_MIKE

Yellow arrow.

bdr_one

What the purpose for the nut is it a tensioner nut or something

rockycat

It is to tension the tbelt. Find and follow the proper way to do that.

It really gets old seeing all these ******* noobs tryin to give out advice when they dont know **** about these cars and even worse to see noobs askin questions they think they already know the answers to.

rockycat

May be a "noob" by thread count but Honda has seen fit to give me Master tech status.

When setting tension on the belt, that nut locks down the timing belt idlers. Installer never physically tightens the belt, that is the job of the spring loaded idlers.

If that nut comes loose the idlers will be allowed to move, causing slack in the belt and disrupting cam/ignition timing.

Also scary to think of damage they could when giving out wrong or just plain bad "advice"

Well I have tore the timing cover off and found the timing belt looks like it had been replaced.Lined up the crankshaft ,and looked at where the cam was sitting according to the marks.I have found the problem to why the engine cant be timed.The cam appeared to be a couple of teeth off.Hopefully when I get this thing together I can get the dizzy timed right and the misfire feeling will be gone.

bdr_one

Does anybody know if the tension idler have a washer behind the acorn nut

Treyschls

some look like this

MAD_MIKE

No washer. But the groove on the nut retains a rubber washer grommet that seals the timing belt cover to nut. #27 90401-PT0-000 ~$3

Replaced the timing belt and oil pump belt ,Now I dont have much tension on the oil pump belt.I think the springs are bad on the tensioners .Did i put the springs in the wrong place
