It is attached to the timing cover, just behind the harmonic balancer, on the lower part of the engine.
It does not have a timing belt. The cam is chaindriven.
depends on what size motor you have in it. if v8 = 18436572
Some people mistakenly change the harmonic balancer or the timing cover, without matching it up. Some had a timing mark located at the top center of the timing cover, and some were off to the side (between 1 and 2 o'clock) If you have a mismatched balancer & timing cover, you will not be able to line up the marks. Sometimes the rubber goes bad, and the outer ring of the balancer slips... which would cause the timing mark to move.
It is possible that the harmonic balancer has spun.check the rubber around the balancer for cracks or decay.If so replace balancer...
there will be a timing mark on the harmonic balancer. and a timing tab on the timing chain cover. point your timing light at the timing tab and you should see the timing mark on balancer. if not timing is way out.markstang.
There is no timing belt on a 305 unless it is an aftermarket belt drive system.
The timing chain is behind the timing cover which is behind the water pump. To get at it, you'll need to remove everything in front of the cover and loosen the oil pan a little.
The timing marks should be on the balancer and the timing cover. If they are not there, someone removed the window marks.The timing marks should be on the balancer and the timing cover. If they are not there, someone removed the window marks.
Sounds like your timing chain might have jumped a notch. Timing is set by rotating the distributor. There is a nut underneath the distributor that locks it down. Timing mark is on the harmonic balancer, sorry I don't have the setting handy. I would start by checking the timing with a timing light. VBdenny
Yes to both questions.
with a timing light on the hermonic balancer NEW ANSWER: The timing is not adjustable, it is controlled by the computer.
The timing marks are on a tab adjacent to the harmonic balancer.
the timing is usually set by adjusting the distributor and using a timing light on the number one cylinder and pointing the light at the harmonic balancer on the bottom of the engine crankshaft pulley,the timing mark on thr balancer should be marked on the correct degree for example 10 degrees before top dead center. as the distributor is turned the timing on the light will adjust to the balancer . to get the correct timing look under your hood for a sticker that has timing and sparkplug gap specs.

Look at your timing scale the 305 times from behind the water pump & the 350 times in front of the water pump.
on the timing cover above the harmonic balancer leon
On the Crank Hermonic Balancer Depending on the year you may not have marks, my 99 has a 3.8 with coil packs, with no distributer you can't change timing unless you do it thru the computer in the car, so there is no need for timing marks.
The Chevy Classic doesn't use a timing belt.
There is no maintenance schedule for replacing a timing chain. Timing chains are designed to last the life of the engine and are normally replaced during a complete engine rebuild.
On the harmonic balancer/driverside
It is located on the harmonic balancer.
