I have a 1990 CRX HF, all stock getting bad MPG (35-40 MPG is all). 230K miles, uses no oil at all, oil at the full mark from oil change to oil change.

I did a full tune-up and found the timing off.

The timing, using a good snap on timing light, is off by 39 degrees advanced.

Thinking the timing belt was off a tooth or 2 I took the car to a good Honda Mech and had the timing belt checked and found it to be right on! But the timing mark is off 39 degrees. The timing belt would have to be off 4 teeth (9.44 degrees per tooth) to make a 40 degree diff.

I had them replace the belt and all the valve cover seals/gaskets.

But the timing mark (the white one on the bottom pulley) is off by 39 degrees.

I have just replaced the EGR valve, plugs, wires, cap, rotor, timing belt, and had the valves adjusted but the timing is still 39 degrees off (advanced).

How/what can make the timing so far off?

The Honda dude does not know but thinks the pickups or something in the dizzy might have come loss.

What about the rotor (wrong one) or?

Any ideas

TIA

here are the timing marks on your engine. Also make sure you attach the timing light to ignition wire for cylinder #1 after the engine warms up.

Thanks for th info.

This is exactly how we set the belt.

But the timing is still 39 off.
