Ok, so I have a '95 850 GLT n/a (obviouslyy) and I recently had my oil changed and they put in an extremely light oil, after a day or so i began to hear a faily loud clicking sound commi8ng from the block of my engine. I took it back and they change oil to 10w-30, and i still hear this clicking noise when i press on the accelerator; i can notice that the clicking sound will will appear at different times durring so many revs if i change the car from econ mode to sport mode.... I havent noticed a change in performance of the car, as i do drive it hard, and would feel it.

What should I do?
What could it be?
Can I fix it?

 

valve tick... try a can of restore from the auto parts store. (oil additive)

 

awesome! thanks man

 

anytime.

 

RESTORE is safe for Volvo?

 

wouldnt see why not... i have used it, no issues

 

i use it, no issues.

everyone always asks "can i use this with my VOLVO?" or "is this safe on a volvo motor?" guys and gals, in the end of it all it is still a basic 4 cycle gas motor with normal bearings and everything, nothing is spectacularly different from a normal motor and your volvo motor.

 

I would also suggest that the next time you change the oil, get a can of engine flush and use it before you change the oil!
