Question about 1991 Nissan Maxima

1 Answer

1991 Nissan Maxima

168,000 miles on it. The upper engine area started making tapping sounds. We tried the oil change with the risoline additive to see if that would clean the lifters and such. Dulled the tapping sound but it didn't go away. I'm trying to sell the car. It would be nice to know what it was so I could call this a mechanics special or something.
Other than the tapping sound, it always ran well. Started right up, ran smooth. Just had the brakes replaced last year.
Any indication of what that tapping sound would be can be very helpful.
Thank you, Marilyn

I have a 2001 ford focus that has a tapping sound coming from the engine. 120,000 miles and the oil is full

Hi when was the last oil & filter change, what engine is it as it will have 2 specific oil types to use, and you need to use the right one for the miles it has done. also when was the timing last checked or changed. there are oil additives that can be used on warn engines. if the engine is more tapping when cold or hot or even no change in temps. How To Quiet any Noisy Engine Valves Lifters or Bearings you can use this type of additives but when you start to use them its best to keep using them. if you have an engine rebuild it would not be recommended to use these.

Lifters problem

my good friend the tap noise you have is not only due to taps failure. Is also coming due to not good oil viscosity and how often you do oil change.My Advice is to do and engine oil flush with a Restore flusher for 40 minutes then drain your old oil drain the old filter and after re-use the old filter with 2 liters of new oil and restart the car and leave it for 10 minutes and then renew oil & filter and use again the Restore friction reducer and every 3000 miles do oil change. If your valves are adjustable do the valve clearance,if not try every 3000 miles to do the same flush way I recommend. It will work unless is a long time working with the tap noise where surely caused damage . Good Luck and let me know with the outcome.

My maxima 2000 makes a sound like an electric antenna when i start the engine, what is your advice, thank you.

My guess would be an oil flow problem. have you had regular oil changes? Sounds like the hydraulic lifters either draining out or not getting enough oil

My 1991 Nissan Maxima won't start. When I depress

Probably a bad starter or battery. Is battery old? Any corrosion?

Tap on the starter - then try and start the car. To find the starter follow the big cable from the positive/red terminal on your battery to the starter.

What kind of oil I should use for a 98 nissan maxima gle

depending on how many miles you have on it.

usually 10W30 for cars around that year. (if you fill it with thinner oil the engine might make clicking sounds, and thicker oil might clog up the engine)

2003 Nissan Maxima Timing Chain

You can wait its just fine, However if you ever start to notice oil leaking from front cover, then you will need to change. If there is no loss in power feel sluggish especially on take off, Its almost impossible for these type of chains to break. So enjoy until the wheel fall good luck

I just went thru this on mine... it is easiest to get to from the bottom right corner... remove the shields and it's right there... take the lower adjustment bolt out , the upper rear bolt and the upper outer bolt out , drop it down and swap wires and replace . Tip; a shorty phillips screw driver works well to allign the holes on the upper rear bolt. DO NOT tighten any of the bolts untill they are all in.
