Question:
We bought a used 07 Nissan Sentra and the engine make a knocking/ticking lifter noise we have taken it to 2 different Nissan dealerships the say it is normal my boyfriend doesn't like the sound he says the lifters sound bad and that at times it sounds like a diesel... so even if this is nothing to be concerned with is there a way to remedy it ?
Answer:
One thing you can try is when it gets warmer outside I would run a little heaver engine oil like a 10-40w engine oil with a Nissan oil filter.
