After replacing my timing belt on a 2001 civic 1.7 the engine is pinging.how do i adjust the timing

pinging in the engine is detonation caused fro wrong air fuel mixture for the accelerator opening and engine load. It is controlled by knock sensors that adjust the mixture in the CPU .IT has nothing to do with valve timing but may be affected by ignition timing . I would be having a compression test done to check for bent valves ( bent during the belt replacement). Have the cam timing re checked as it may be still out a bit.

The factory calls for replacing the belt every 110,000 miles

Timing Belt and Tensioner REMOVAL & INSTALLATION 1984–87 Engines

1. Turn the crankshaft pulley until it is at Top Dead Center.
2. Remove the pulley belt, water pump pulley, crankshaft pulley, and timing gear cover. Mark the direction of timing belt rotation.
3. Loosen, but do not remove, the tensioner adjusting bolt and pivot bolt.
4. Slide the timing belt off of the camshaft timing gear and the crankshaft pulley gear and remove it from the engine.
5. To remove the camshaft timing gear pulley, first remove the center bolt and then remove the pulley with a pulley remover or a brass hammer. This can be accomplished by simply removing the timing belt upper cover, loosening the tensioner bolts, and sliding the timing belt off of the gear to expose the gear for removal. NOTE: If you remove the timing gear with the timing belt cover in place, be sure not to let the woodruff key fall inside the timing cover when removing the gear from the camshaft. Inspect the timing belt. Replace if over 90,000 miles old, if oil soaked (find source of oil leak also), or if worn on leading edges of belt teeth.

   To install:
   
6. Be sure to install the crankshaft pulley and the camshaft timing gear pulley in the top dead center position. Align the marks on the camshaft timing gear so they are parallel with the top of the cylinder head and the woodruff key is facing up. NOTE: When installing the timing belt, do not allow oil to come in contact with the belt. Oil will cause the rubber to swell. Be careful not to twist the belt unnecessarily or bend in a 90°angle, since it is made with fiberglass; nor should you use tools having sharp edges when installing or removing the belt. Be sure to install the belt with the arrow facing in the same direction it was facing during removal.
   
7. After installing the belt, adjust the belt tension by first rotating the crankshaft counterclockwise 1/4 turn. Then, re-tighten the adjusting bolt and finally the tensioner pivot bolt.
8. Replace the other components removed for belt access.
9. Start the car, check timing and adjust if necessary WARNING
   Do not remove the adjusting or pivot bolts, only loosen them. When adjusting, do not use any force other than the adjuster spring. If the belt is too tight, it will result in a shortened belt life.
   

Solution 1 would be to diagnose the problem of the low comp in 2& 3 and solve that issue. I would of started w the timing belt 1st. If that didn't solve it,ck head gasket, valves,rings. CK for oil & coolant mixing. Good Luck

We cannot stress this enough: Be careful! Make sure you know where the timing marks are on your engine, and that you have them set up properly with No. 1 cylinder at top dead center (TDC) on the compression stroke before attempting to replace the timing belt.

Why? 1) That interference engine thing again; and 2) Every camshaft and crankshaft on planet Earth is indexed to No. 1 TDC. If you try to remove and replace the timing belt with the engine in any other position, chances are good you'll throw things out of time. Then you'll get confused and have to pull off the valve cover as you try to determine when No. 1's valves are closed (which begins the compression stroke) in order to re-index the engine. Get your marks lined up right the first time.

It is not an eays job. I would have it done by a tecknician so you have a warranty. The honda dealer is your best bet because you will oem parts and the job will be done right . then you are good for another 90,000 miles. I hope this helps. Don't forget to rate my answer.

maybe its low on oil

The only other thing could the the timing belt tensioner if there is any doubt. Here's the timing marks.

I know of no adjustment for the timing belt, they have a spring loaded tensioner that keeps the belt tight. Honda wants you to change the belt every 90,000 mile. I would always change the tensioner and the water pump, which is driven by the timing belt, at the same time. If there is any question about how long the belt has been on the engine, replace it, you do not want the belt to fail at highway speed.

The ticking sound is probably an out of adjustment valve.This can cause performance problems if it is severe enough. Go to www.georgebelton.com/6g.civic.tech/valve.clearance/index.php for step by step instructions w/ detailed photographs for this repair. The timing belt is one of those type of things that works 100% or not at all. At 126,000 miles I recommend having the belt(s) replaced. It is fairly inexpensive to have done and will extend the life of your vehicle 2 fold. If you belt fails it will probably destroy your motor so it is money well spent. Good Luck!!!
