I need to know the Timing marks on a 93 sentra GA14 I can't seem to figure out the exact timing on it

GA14 NISSAN SENTRA model 1988 no rocker arm direct to cam lobes all intake and exhaust valve. what the procedure to adjust the between the camshaft lobes to valve steam.

Here are the diagrams showing how to set the cam timing.

See , the fuel pump regulator is a sealed unit and all you can do is check for vacuum and hook up a fuel pump tester and check for pressure and volum.

sincerely. Merry Christmas.

• Here are the diagrams you requested.

You want to wipe off the links of the lower timing chain next to the timing marks on the sprocket and put paint marks on the timing chain matching them with the timing marks on the idler sprocket and crankshaft sprocket.

Regards, Tony

There is 3 marks on the timing chain, 2 are exactly 16 links apart and the other is 22 from either of the 2. The engine should be at top dead center. Line the 2 (16 apart) marks with marks on your cam gears and the 3rd with your crank gear. Torque cam bearings to 100 inch lbs.

The timing marks indicate degrees of advance. Thus, the first mark would be top dead center and in increments of two it increases to 10 degrees before top dead center.

Mark the direction of rotation on the timing belt in case you need to re-install the original belt


Cam and crankshaft sprocket alignment positions for the 2.0L engine


Rotate the crankshaft until the timing marks (arrows) on the camshaft sprockets align with each other


Please don't forget to rate

What motor and year? If it is the Ej 25 DOHC all the marks are on the cam sprockets except the crank is marked in the block almost straight up, Just a small notch. Good luck and hope this helps. Have a good day.

Step1 First step is to open your hood on your vehicle and locate the distributor. Step2 Next loosen your distributor just enough that it will turn from side to side with some resistance. Step3After Loosening the distributor take a piece of chalk and mark on theharmonic balancer the timing mark so it can be seen easily. Step4Then take the timing light and connect it to the battery and the Numberone spark plug wire. Then have your helper start the vehicle while youshine the timing light on the harmonic balance and the timing mark onthe timing chain cover. Step5The Timing Light will illuminate the mark on the harmonic balancer whenthe Number one cylinder is firing. The mark should correspond to thetiming mark on the timing chain cover. You can then adjust the timingforward or backwards by rotating the distributor ever so slightly. Step6 When you have the timing where you want it then shut off the engine and carefully tighten back down the distributor without moving it.

The belt tensioner is located under the timing cover. It is 1 1/2 round and about 3/4 inch with a groove in the middle where a bolt is tightened. When you remove the timing cover you will see the timing belt, the camshaft sprocket and the crankshaft gear. The timing belt goes around these components.. The belt tensioner is loosened and the new timing belt is placed. The sproket also has to be replaced if it is broken. Be careful to notice the little marks that are aligned on the sproket and above the camshaft.. They can be small arrows that have to be aligned exactly the way you took them off. replace the belt and you tighten the tensioner so the belt fits snug and tighten the bolt in the middle of the belt tensioner. It is not too difficult, if you know something about mechanics. If you don't, you will be better of taking it to somebody who does know.
