Ask Smithy Xtra leaky Mazda 626

Asked by Damien Clarke

My 1991 Mazda 626 has had an easy life with regular servicing and has had no reliability issues to date, but it has starting leaking a little oil and is also burning oil on a cold start. I would like to keep the car as it has never broken down, overheated, etc and I don't really have the money to buy a new car. What might cause the problems?

It’s an old car and you have to expect some wear and tear over what is now coming up for 20 years. Smoke on a cold start isn’t necessarily oil related; it is often condensation and nothing of concern. The oil leak is probably just a gasket that has hardened or split and needs replacing. If it is burning oil it could be due to wear in the valve guides or it could be worn piston rings or wear in the bores. If it’s not leaking a lot, just leaving a spot on the driveway, and it’s not using much oil I wouldn’t be too worried about it. The worst-case scenario would be that engine might need reconditioning.
