Question about 1996 Nissan Maxima

Nissan Timing Chain still rattling

Hi,

I rebuilt the engine in my 94 Nissan Altima. It has a brand new cylinder head and timing chain kit installed, including a new tensioner.

At normal idle the chain rattles. I removed both upper chain guides and it still rattles, this time sounds like it is hitting the head itself.

Any ideas? Is it possible the chain is slightly to long? tensioner bad even though it's new?

Thanks,
Ryan

    Yes, I did replace the tensioner. And yes, I also pulled the pin.

    I had the block hot tanked at a machine shop so I am pretty confident the oil gallery is clear.

    Last week I took down the upper chain cover to examine things, and I noticed the chain was very tight. I mean, I had to press very hard against the tensioner to loosen the chain enough to take it off. Does that mean it is working correctly?




  • rpreeves Apr 16, 2009

    No a dealer has not looked at this, but the cylinder head shop that provided the head did and they said it was the chain.

    I am confident it is the chain making the noise because it goes away at high RPMs (hence, higher oil pressure I guess). Also, the "texture" of the sound changed after I removed the guides. Before it sounded like hitting a screwdriver against a steel bracket. Now it sounds like it's hitting a solid piece of aluminum.


  • rpreeves Apr 16, 2009

    No scar marks. The head was a different, reconditioned head, so I'm not sure if it was resurfaced or not.

    I bought the entire engine rebuild kit from JIS Engine (jisengine.com)


  • rpreeves Apr 16, 2009

    Yes, I actually had it all off last week. I didn't see anything abnormal, and the chain was very tight.

    Is it possible my oil pressure is low for some reason?

    BTW, I appreciate all the responses to my problem.

    Funny you suggested that. I actually bought and installed a dash gauge last night.

    On my way to work this morning on the interstate I got 60-75 psi. At red lights and stops I got 15-20 psi, which is when you can hear the rattling sound.


  • Anonymous Apr 20, 2009

    If the head I replaced was one that had been resurfaced and therefore causing too much slack in the chain, what can I do about that?

  • rpreeves Apr 20, 2009

    i replaced that one

  • Richard Scordino May 11, 2010

    When you opened it up did you see any scar marks where the chain is hitting? Also, when the head was rebuilt, was it cut? Last, if you got your tensioner or other components from SA Gear co, they have absolutely no quality control...therefore anything from there is suspect.

    If the chain is tight, that's good, I'm wondering if there might be something else hitting. Are you absolutely sure the chain is on correctly? I recently ran into a problem like this with BMW 318, chain driven dohc 4 cylinder. The owner did the chain but put it on one link out and the valves were just barely hitting the pistons making quite a noise that really sounded like the chain.

  • yadayada
    yadayada May 11, 2010

    then based on what u say about the chain your rattle is not the timing chain, better look elsewhere. has a Nissan dealer listened to this noise? They would know right away what it is.

  • Dave  C

    This engine has a hydraulic chain tensioner that receives oil pressure from the block where it is bolted on. Are you sure that the oil port on the block was clear? Also, when you buy these new, sometimes they are pinned so that they don't fall apart during assembly. Once the chain is on and timed properly, you remove the pin so that the piston can come out and do it's job. Did you pull the pin?

  • yadayada
    yadayada May 11, 2010

    did you replace the timing chain tensioners?

  • yadayada
    yadayada May 11, 2010

    15-20 psi at idle is within normal pressure range, be it the lower end, if it were to low (10 psi) the light would come on.

  • yadayada
    yadayada May 11, 2010

    put a gauge on the engine and measure the hot engine oil pressure.

  • Dave  C
    Dave C May 11, 2010

    Can you get the timing cover off and have a look at the whole mess without removing the engine, this will also give you a chance to have a look for marks on the inside of the cover?

  • Richard Scordino May 11, 2010

    If the chain is touching anything, it will leave a mark (like a chainsaw) If there are no marks, likely the possibility exists that cam phasing may be off and valves are striking piston tops. (very bad thing) The only thing you can do is to re-check cam and crank gear positioning or have someone actually look inside the chambers with a bore scope
    (very expensive) camera that can look inside and actually see what's going on inside cylinders...some really good shops and dealers have them. Reason I asked about resurfacing of head is that if it was taken down too far, chain slack will be more than tensioner can compensate for. Also in some engines can cause valve/piston clearance problems.

I have a 2002 Nissan Altima 2.5L. When i drive more than 11 miles, it sound like the timing chain is rattlling inside the engine. But if i stop and shut the car off for like ten minutes then the rattl


There is, in fact, a timing chain on your car. Unfortunately, the Altimas around this year have issues with stretched chains. This car probably should not be driven. If the chain breaks, you will destroy your valves and need to get your head rebuilt. The parts for this repair can be had for under 100 dollars, however, the labor involved is quite a lot. I was quoted $1000.00 for the job and thought it was too much until I got into it. Very time consuming and not for a beginner mechanic. If you know someone who is a VERY good mechanic, maybe they can give you a break on the labor.

I NEED TIMING CHAIN DIAGRAM FOR VQ20 NISSAN SERFIRO 1999


Instructions
  1. Remove Your Timing Chain
    • 1 Check your owner's manual for the recommended mileage for replacing your timing chain. Replacement for a Nissan Altima is 60,000 miles.
    • 2 Locate the timing chain. Replace it if the automatic chain adjuster (also known as the tensioner) is damaged or worn.
    • 3 Drain the cooling system and disengage the negative battery cable. Undo the spark plug wires and set the No. 1 piston at "Top Dead Center" (TDC) of the compression stroke.
    • 4 Disconnect the engine undercover, vacuum and fuel hoses, harness and connectors, drive belts, power steering reservoir, alternator and bracket, upper radiator hose, air duct, front exhaust tube, intake manifold collector supports, collector and exhaust manifold and the distributor.
    • 5 Prop up the oil pan and take out the front engine mounting, the valve cover, camshaft sprockets, cam bearing caps, camshafts, cylinder head bolts (reverse the installation order), cam sprocket cover, upper chain tensioner, chain guides and chain, idler sprocket bolt, cylinder head, intake manifold and cylinder head gasket and the steel oil pan.
    • 6 Place a steel cutter between the steel and aluminum oil pans. Slip the cutter around the oil pan's edge. Disengage the steel oil pan, baffle plate, oil strainer and the front tube.
    • 7 Secure the car on jack stands and place a seal cutter in between the oil pan and cylinder block. Slip the cutter around the oil pan's edge.
    Install Your Timing Chain
    • 8 Reconnect the crankshaft sprocket, oil pump drive spacer, idler sprocket and lower timing chain. Position the lower timing chain on the sprockets and line up the mating marks.
    • 9 Rub on an unbroken bead of liquid gasket and put in a new front cover and oil seal. Secure the bolt at 105 to 112 foot pounds (142 to 152 Nm).
    • 10 Eliminate any old material from the pan and cylinder block mounting surfaces. Rub on a 3.5 to 4.5mm bead of liquid gasket over the oil pan and cylinder block.
    • 11 Attach the upper timing chain to the idler sprockets and secure the cylinder head bolts.
    • 12 Refill the cooling system and add clean oil in the engine.
    • 13 Hook up the negative battery cable and any other disconnected parts or items. Start the engine and look for leaks.
Tips & Warnings
  • Procedures for replacing timing chains in Nissan Altimas vary slightly depending on engine size.
  • Make sure the new timing chain matches the chain you are removing.

Does 2007 altima 3.5 have a chain or timing belt


After 2002 Altima offers two types of engine: the new 4 cylinder 2.5 L QR model engine which is fairly powerful (175 horsepower) and, I believe, one of the best engine in its class the 3.5L V6 VQ model engine with 240 horsepower. The same V6 model as in in the Nissan Maxima, Pathfinder and Murano.
Both engines feature continuously variable valve timing using a silent chain instead of timing belt. Throttle cable is gone - the throttle operates electronically by wire based on gas pedal sensor readings. This design provides smoother transmission shifting and lower emission.
The 2007 Nissan Altima 3.5L Sedan, has a Timing Chain, and an Ignition Coil Pack. NO DISTRIBUTOR.

Timing chain tensioner


I have a '94 Altima with 2.4 liter 4 cyl. engine. At around 150K the timing chain and tensioner were replaced - should solve your problem, too. If you're sure the chain is rattling you should really get it serviced now, not later. Also, if your car is running rough it could be more than just the chain and tensioner; it could be your ignition system, such as plugs, coil, distributor, etc. Bottom line is, your car needs to be checked out right away.

What will my car sound like, if the timing chain needs to be replaced? I have a 1997 Nissan Altima.


there will be a rattle the front of the engine. the end with all your pulleys and belts on. And it will be hard to work out if it's in the engine or the pulleys.

It is a common that a TICKING coming from the front of the engine is the timing chain guide.
