85 oldsmobile cutlass supreme

when i bought the car i was told it was a loud knocking noise but when i started it …it wasnt so loud…i was told it might be the lifters…and the timing

Do you have a question?

Change the motor oil to Hi-mileage 10-30w. Run that awhile. If you still hear the noise, try one of the fine “valve quite” products from the auto parts store. As a last resort, you could have a mechanic look at it.
