Question about 1997 Toyota Camry
1997 camry 2.2 ltr. automatic. Oil leak passenger side when engine is running only. About 1. qt. per 10 miles driven. Oil sending unit sprayed all the oil out and car was driven 40 miles w/o oil. Could this be because the catylitic converter is clogged? Shop said engine has back-pressure. Could it be the head or valve cover gasket(s)? I did replace the oil sending unit and also tried stop leak to no avail. After the oil sending unit went out, there is now a buzzing/humming sound from the engine. Could this be the balance shaft and or cam shaft bearings? There isn't a knocking or pinging sound, it just sounds like there's bumble bees in my engine. No codes are showing. No check engine light showing. Looks like the oil leak might be coming from the upper part of the engine area (passenger side) in the upper back right, where the valve cover gasket is located. There's also a small black hose that looks like it might be where the leak is coming from. Thank you for any help you can give! This car has 212,000 miles on it and my be time to trade and not put too much money into it. Are there two catylitic converters on this car? I heard the front one is $1,000.00 just for the part? I need this car to drive to Cincinnati, Ohio every other weekend to take care of my 88 year old Mother and I also drive 150 miles round trip each day to work and back Monday thru Friday and 800 miles every other weekend. Oregon, Illinois to Hoffman Estates, Illinois. I'm a flavor chemist by trade.

The noise might be oil on the timing belt. The oil leak might be from the oil pump gasket. The oil pump is ran by the timing belt and the leak would saturate the timing belt. Inspect the belt

Take the filler cap off and see how much pressure there is. you should not have very much. Also check your PVC valve. For the oil leak, does the car have a electric oil sending unit or is there a hose going to it? when you replaced the sending unit do you show oil pressure inside your car? if it is a manual sending unit, then there will be a very small hose coming from it. it is about the size of a very small straw/ or like the red straws used with WD40. make sure that it does not have a hole in it or if it is broken. you have 60 lbs of oil pressure at that sending unit.
