In Summary

Hello Paul, I read your article in Daily Monitor about a shrieking noise and I seem to have a similar problem. I have an old vista which makes a really bad noise that becomes louder each day. It also emits black smoke from the exhaust and the oil level depreciates rapidly. Each week, I have to refill with a litre of oil that is if I do not drive long distances. Naswif

Hello Naswif, noise in the engine and oil loss or leakage into the engine are signs of a damaged engine. Two things may be happening. First, engine oil starvation or restricted delivery of oil to the fast moving engine parts hence the noise in the lower engine and valve train areas.

We would need to carefully examine your car engine to confirm oil pressure, which may be a precursor of fast moving parts running dry. Secondly, there is a likelihood of an oil leakage past worn out piston rings (seals) into the combustion chamber.

This is consistent with the black or blue smoke which confirms poor fuel combustion and burning of engine oil and fuel air mixture. We can carry out a compression test using a special tool to confirm the above damage. Then guide you to your next big decision to repair or replace, based on conclusive findings.
