It would help if you state what kind of oil leak (or where the oil leak is) ? Depending on where it is the complexity can change drastically.

Well, the oil level reduces a lot, however there are no identifieable oil spots under the car when it's parked and it seems like it loses oil when the engine is running. Coolent level is not affected and there aren't any white smoke or smells while the engine is running.

Recently the car was lifted to do a suspension repair at auto miraj and they pointed out that there's a oil drop and a possible oxidation on the gearbox and engine joining bolts and said it's probably leaking oil from the main seal.

ps: the tappet cover packing was replace by A*W last year too but there aren't any visible oil streaks around that area.

It could be that your crank seals are spoiled, and the oil is seeping into the transmission/bellhousing. 

What a lot of people in SL get wrong is they focus on just fixing visible oil leaks. The thing is if one seal is spoilt the chances are it won't be too long before other seals start going bad too (unless you have verifiable proof that it was replaced within a recent amount of time in the past). Second mistake is people think that if the mileage is low it doesn't matter even if it has been 10 years. The thing is, these materials degrade with time. So even if the mileage is low seals, etc...need to be replaced.

yeah true, the last owner has changed the main oil seal about 8 years ago from Toyota (lol, not sure why not A*W). Also, the mileage is 192K so probably the seals have gone bad. I was just wondering about a good garage because I'm tired of makabases. I guess the best options would be to take the car to Toyota's pitstop or AWM then

Sorry I am not in Sri Lanka so don't know which garages are still good (the level of service keeps changing frequently). I usually get my stuff done at SpreyMech because of known people and an old school old gentleman.

Depending on how long you plan on keeping the car you might want to consider giving the entire engine a refresh (i.e. changing all oil seals, decarbonization, etc...)
