A person can sync the timing belt on a 1990 Rocky SUV by aligning the timing marks. These can be found on both the camshaft sprocket and the crankshaft sprocket of the engine.
if your timing belt jumped one tooth or timing belt was installed incorrectly you will be out of sync also a defective timing belt tensioner will cause sync problems
The most common cause for no compression after a timing belt change is improper timing. Make sure that tdc is set correctly, and is not 180 degrees out of sync.
it has a chain.and needs to be set in sync with the distributor
probably put the timing belt out of sync
It probably has a belt, not a chain, but chains are in the same location.The timing belt is located under the timing cover. The timing cover is the plastic or metal cover at the front of the engine (the side where the fan belts are).This vehicle has an interference engine, which means that the valves can be damaged if the timing belt breaks or gets out of sync. This job should be done by a professional only.
The main cause for bent valves is a failure in the timing chain or belt. When the valves and pistons are not exactly in sync, they can collide.
In a VW Polo diesel, the timing belt is located at the front of the engine, underneath a protective cover. It connects the crankshaft to the camshaft, ensuring that they rotate in sync to regulate the engine's timing. Accessing the timing belt typically requires removing various engine components, including the engine cover and possibly the front bumper, depending on the model year. Regular maintenance and inspection of the timing belt are crucial to prevent engine damage.
A timing mark is usually a white line on the timing belt to sync the firing of cylinders in an engine. You can see this line when the engine is turned off or with a timing light also a strobe light when the engine is running.
Valves can be adjusted via the rocker arms, under the rocker arm cover. Remove this via the service manual, and they should be adjusted to give a small clearance, appx .02 inches. Timing is a different story, if it is your valve timing, you need to locate the timing belt or chain adjuster, and get a timing light. Sync the timing light to the timing mark on the belt or chain via the adjustment mechanism.
Unfortunately I fell victim to a "bad timing belt" in my 98 Audi A4. I guess the belt becomes worn and breaks. It ultimately causes the whole engine to run out of sync, leading to damaged cylinder heads and most other parts. Luckily I had all of my service records so Audi payed for all the new engine parts. If you got a letter in the mail from Audi then go get your timing belt checked ASAP. Unfortunately I fell victim to a "bad timing belt" in my 98 Audi A4. I guess the belt becomes worn and breaks.

If a timing belt breaks on a VW T4 the same as most other vehicles it could severly damage the engine as the pistons, valves and camshaft are no longer in sync and will hit each other. Normally the above results in bent and damged valves at the very least.
yes.....it is an interferance engine. The belt keeps moving parts in sync; when it breaks at speed, those parts can hit each other with great force.
