good chance the cam and crank shafts were not aligned properly or the engine just needs to be timed correctly
The timing on a Toyota 2Y engine is typically set to 10 degrees before top dead center (BTDC) at idle when the engine is warm. It’s important to ensure that the timing belt or chain is in good condition and properly aligned during maintenance, as improper timing can lead to engine performance issues. Always refer to the specific service manual for the exact timing specifications and procedures for your model year.
The timing is computer controlled, there is no adjustments. I know this is a little late, but timing could be off because the timing belt is not properly aligned. If the timing belt is installed incorrectly the timing will never be right.
The timing will be off and the engine will have no power and get poor mileage. In some cases if the engine is an interference engine you could have serious internal engine damage if the belt is installed incorrectly.
To set the timing for the Isuzu 4HF1 engine, first ensure that the engine is at top dead center (TDC) on the compression stroke for cylinder one. Then, align the timing marks on the crankshaft and camshaft gears according to the specifications in the service manual. Once aligned, check the timing of the injection pump and adjust it if necessary, ensuring the pump's timing mark aligns with the specified mark on the engine. Finally, secure all components and recheck the timing before starting the engine.
To set up the timing on a Mazda T3500 diesel pump, first ensure the engine is at TDC (Top Dead Center) on the compression stroke for cylinder one. Remove the timing cover and locate the timing marks on the pump and engine. Align the pump's timing mark with the engine's timing mark, and then secure the pump in place. Finally, recheck the timing by rotating the engine and verifying that the marks remain aligned before reassembling any components.
If the original belt didn't break and it was just replaced , the timing marks were not aligned when the new belt was installed. If the timing marks are not aligned or moved during replacement, the engine is out of time and firing when valves are not in the proper position. If the belt broke during operation and then replaced, the belt can be installed correctly with the timing marks aligned however when the belt broke the pistons (still moving) and the valves(not moving) came in contact and bent one or more valves and are now valve(s) not sealing properly when they close. Valve sealing can be checked by performing a compression check on each cylinder, it will be obvious if a cylinder is bad if the compression shows little or no compression.
If you have installed a timing chain and the engine will only turn a half a turn, you are out of time and may have bent valves.If you have installed a timing chain and the engine will only turn a half a turn, you are out of time and may have bent valves.
Both the crank and cam sprockets have timing marks on the sprocket and on the engine. As you face the front of the engine, with the sprockets in front of you, the cam timing mark is approx. 85 degrees right of top center. The crank mark is approx. 10-15 degrees right of top center (piston #1 should be top dead center). Line marks on sprockets with timing marks on block (tin), slip on belt and tighten tensioner. Manually rotate engine 2 complete revolutions and check that both marks are still aligned.
On a 2001 Suzuki XL-7 with a 2.7L engine, the timing marks for the upper timing can be found on the camshaft gears. There are usually alignment marks or notches on the cam gears that should be aligned with the corresponding marks on the engine's timing cover. It's crucial to ensure these marks are properly aligned during timing belt installation or maintenance to ensure correct engine timing. Always consult the service manual for specific details and diagrams.
To set the timing marks on a 2005 Chevy Aveo, first ensure the engine is at top dead center (TDC) on the compression stroke for cylinder one. Locate the timing marks on the crankshaft pulley and the timing cover; align the mark on the crankshaft pulley with the TDC mark on the cover. Next, check the camshaft timing marks, ensuring they are aligned properly with the corresponding marks on the cylinder head. If necessary, adjust the timing belt or chain to ensure all marks are aligned correctly.
To set the correct timing on a 1.7 TD Opel Astra, first ensure the engine is at top dead center (TDC) on the compression stroke for cylinder one. Align the timing marks on the crankshaft and camshaft gears, ensuring the timing belt is properly tensioned. Double-check that the timing belt is correctly routed and that all timing marks are still aligned after tensioning. Finally, rotate the engine manually to confirm there are no obstructions before starting the engine.
