This is Toyota Camry 98 with V6 3.0 engine.
After smelling burnt oil while driving (mostly during stops, to be more precise), I took the car to Toyota service mechanics. They found leaks in both valve cover gaskets, and a leak from behind the timing belt cover. The leaks from valve covers were dripping onto exhaust, causing the burning smell.
The total repair cost is quoted at around $2k ($700 for valve covers and $1300 for what is behind the timing belt assembly).
Is it worth doing ? My worry is that, since 3 separate seals are failing, it is likely that other seals will start failing soon.
Should the whole engine be rebuilt instead ?
Thank you in advance for advice.
