The likely hood of all being blown is unlikely. Infact, I'm pretty certain it would take dozens of spins to get them to line up again. Runs great, engine smooth and quiet. Im thinking this because the sprocket becomes advance after rotation, a tooth before the reference mark on the cam sprocket and if im correct the solenoid uses spring tension and oil pressure to change the timing on the intake cam right? I don't yet have a Factory Service Manual for this Sentra so I'm guessing on this one. Ok, what i did do is, that on the tooth of where the aligning dot is on the cam sprocket, i colored that tooth in, to align with the timing covers and they all lined up.
Exhaust and crank marks lined up perfectly. It was extremely jarring, to say the least. Loosen the 14mm bolt in the center of the idler pulley, and then lo … osen the 8mm tensioner bolt till the belt can be slipped off. Long story short, had to change my timing belt and found that i tensioned it wrong. Adjust the ignition timing to spec. A friend said I should check the timing as this could also cause the problem. Suspected a timing chain problem on my 1997 Nissan Sentra with 128K and a 1.
Noise will stop after hydraulic pressure rises. It's far from a perfect fit. Manuals are in Knowledgebase section at the top menu tab. Removed, intake cam valve cover to check for anything out of the ordinary and didnt find anything. Reverse the process to install the new belt. Need to perform a compression test, to confirm this i dont have a air compressor to perform a cylinder leak down test.
My point is, if you put the belt on with all the dots lined up on the timing cover marks, you should be good to go once the tensioner is set properly. Remove them carefully ,tap on housing to remove, and thermostat is within. This engine has an automatic chain tensioner that keeps the chain tight so that it will not jump teeth when stretched due to wear. Here is a list of the tools you will need. I don't know why everyone went from using timing chains to belts on new cars, other than it is built in money for the dealers. You have done a lot, but there are some basic things you did not mention. Just trying to see if im missing something before i have the thought of having to tear the motor down.
Refill to the specified level, if necessary. Once your timing is set, recheck you base idle and adjust, as necessary. If you are planning on changing the belt then you will have to remove the powersteering belt too in order to get it off. I want to stress that it has trouble starting at all times now, cold or hot engine. Theres lots of bulbs in the dash, glove box, ash tray, Speedometer, heater control and console gearshift.
Popped the valve cover and discovered a lot of slack in the upper timing chain. To make things easier to rotate and to better feel if you have valve contact before damaging and overturning, I usually pull the plugs so that it doesn't build up any compression in the cylinders. Thanks for replying, and thanks for letting me know about the service manuals. If my memory serves me incorrectly, then they were replaced approx. Is the inspection result normal? Posted on Aug 11, 2009. However, this now happens on city streets, as well, at very low speeds and when hardly accelerating.
You might try a compression test too. From budget to performance build, Melling timing chains offer you the coverage and choices you desire. The 1994 Nissan altima has a timing chain. Looking for the suggestions on the next step to take. It certainly would be consistent with a hydraulic tensioner just before getting oil pressure. If the distributor is installed properly and after re-connecting the components such as plug wires, etc.
Procedures Performed Fuel Filter Per a recommendation on a forum etcg, to be specific , I replaced the fuel filter when I first posted somewhere attempting to solve my issues. The headlight switch can fail but you'll say the tails don't work and the fuses are good and they were good when you checked them. However, when I called the local Nissan dealer for my 2003 Sentra, they told me it does not ever need to be replaced. If you would like to see if everything is still where you set it, simply turn the engine counter clockwise two turns and the belt marks etc should be back to where you set them, but the manually added reference marks should usually be enough to convince you that it's where you left it. I have a Nissan Sentra 1.
The engine would not run if this was not the case. If you have to adjust idle speed, refer to page 35 of Engine Control Manual. You can always make your own marks for future reference. How much deflection should slack-side of upper chain have? So here's something from Memory. Does it happen all of the time? I usually put a third mark indicating where I had my crank sprocket too to avoid any tdc errors.
