Oil Leak So I recently had my rear main seal replaced but oil still leaked. Took it to another shop and they replaced the left front axle seal but the oil leak still persisted. Now I want to know what type of repair will I have to make in order to fix this oil leaking problem?

SOURCE: Rear Main Seal Leak

To replace the seal, the mechanic will have to either lift the engine or lower the transmission. You will get much better pricing going to a transmission shop (e.g. AAMCO) and getting a quote from them to replace the seal.

Just had axle oil leak, left front, had axle replaced, could this have been prevented or is it natural wear and tear?


Hi Dolores ! by replacing the axle shaft have you changed also the oil seal on the gear box or not? If not surely is the old oil seal and is leaking.

Oil leak front engine timing chan


1995 Tracker would have a timing BELT. Normal oil leak points (in order) on a Suzuki G16 engine are the distributor base (rear of motor), valve cover (top of motor), front main seal (behind lower timing belt cog) cam seal (behind the upper timing belt cog) and rear main seal. (behind the flywheel). I'd suspect the front main seal or cam seal. I use foot power to help find oil leaks.

Oil leak on driveway coming from front of engine


Dear Sir,
Here is the oil leaking Problem Identifying Technique

Engine oil leaks from the valve cover gasket are common.

  • The intake manifold plenum gasket may leak and cause increased oil consumption/burning and a spark knock during acceleration; the gasket should be replaced.
  • External oil leaks from valve cover gaskets, intake gaskets (front or rear), and the rear crankshaft (rear main) seal area are common. The rear main seal is an unlikely source. Normally, the bearing cap mating surfaces (as well as the sealing surface between the oil pan and bearing cap) are the source for the leaks.
  • Engine oil leaks at the distributor can be misdiagnosed as leaks from theintake manifold seal, oil pan gasket, or rear crankshaft (rear main) seal. A revised distributor is available if oil is found inside the distributor.
  • If the oil filter casing shows signs of distortion from excessive oil pressure, theoil pump should be replaced.
  • Often misdiagnosed as a leaking oil filter gasket, the oil filter adapter can seep from between the adapter and engine block.
  • Carbon buildup on the top of the piston is common. As the buildup increases with mileage and over time, symptoms may vary from light ticking, to ticking/hammering, to hammering/knocking noises. Fuel injector cleaner often solves the problem.

    My side rearview mirror was broken by someone or something running into my mirror and I have a oil leak thats in the undercarriage. approximately how much is this going to cost to get it fixed?


    look on ebay for mirrors replacement or junk yard, it will save you allot and you can do it yourself just by popping the mirror cover off on the opposite side of the door to access the bolts that hold the side mirrors on. 10 minute job. the mirrrors should cost you 25-50 bucks depending on condition of it. if the mirrors is diffrent color, it will need to be repainted to match the car, 50-100 buck depending on the shop, check macos, they are cheap or call around and shop and get couple estimate wont hurt. Lots of car dealers use those portable/mobile touch up guys, the dealers used them to fix and touch up all of their cars, you might want to stop by some dealership and ask one of the used car managers ask him/her who they use and phone number, those portable/mobile touch up guys does very good job, cheap and fast. oil leak under the car, can be transmission leaks or you rear main seal, common to high miles cars to leak from the rear main seal which they have to remove the tranny from the motor to get to it, the parts is cheap but the labors will get you. you probably looking if the rear main seal, 500- 900 bucks depending on the shop. you can drive on the leaks as long you keep the tranny fluid monitor making sure the fluid does not go empty in the transmission.

    Oil leaking in engine have replaced seal and O rings but still leaks. I am going to scream!


    ok, There are many areas that the oil could leak from. Head gasket, oil pan gasket, rear main seal, front seal, valve cover gasket. You'll need to locate the leak under the car in order to know which one to replace. There is nothing simple about replacing the rear main seal and although he front seal is easier it can still be a problem. Good Luck.

    First I'd find a different shop. $100 to look at it? I don't think so. Sounds like this may be a transmission issue.

    Oil Leak


    i would have to say the oil pan gasket. that is the one that I have replaced more often. it is ever usual for the rear main seal to go out but not impossible. but i would have to say oil pan gasket.
    hope this helps and if you need anything else let me know. happy holidays.
