When you turn the engine over with the starter, which way does it turn? That is the direction it rotates.
It is a variable valve timing innovations from toyota, where in power and fuel efficiency can be optimized by varying the timing of the camshaft with respect to the crankshaft of an engine,by retarding or advancing the camshaft by a certain phase angles.A conventional engine has it's camshaft rotate half the crankshaft rotation and the performance of a such engine would be in it's peak efficiency for a single speed only.Engineers developed a technology to overcome this in-efficiencies by introducing variable valve timing where camshaft rotation can advance or retard with respect to the crankshaft,hence optimising performance and fuel efficiency.
what is the timing marks on the camshaft what is the timing marks on the camshaft
Timing chain
Timing belt
when installing a new timing belt and cam sprokets are removed to replace cam seals the tool holds the camshaft in place
You can set the camshaft timing on your automobile by lining up the timing marks. There will be timing marks on the front main pulley and timing marks on the camshaft.
The 4.0 litre V6 engine in a 2006 Nissan Pathfinder has a timing CHAIN
Timing chain
You don't. It has a Timing Chain
Get a shop manual from the parts store and it will show you what to set them at and give tips on how to replace it. GoodluckJoe
With the 3.5L motor it is definitely a chain. Should be maintenance free, but if it or the camshaft are not being properly oiled it could lock up causing extensive repair costs.
