Drivers side timing cover leaking oil. One place says it is just a gasket another thinks it is cam phasers leaking the oil. Which one is correct?

    Could one of the problems be the cam seal? Is that also behind the timing cover? I lose about half a quart in about 1,000 miles. Would a conditioning oil that is supposed to help fix seals be worth while for a short term fix or is that stuff a gimmick?

Its just a gasket at this point. There is no way to say if something behind the cover is the issue without removing the cover.

    Is the cam phaser behind the cover? Or better where is it located to make the tech think it is the cam phaster leaking?

    He is just taking a guess at what the problem is without being able to see it. Timing covers dont hold back oil. They are a housing for the timing belt, crankshaft gear, camshaft gears, tensionor for the timing belt, and sometimes a water pump.

    There is no oil supply there so if oil is coming from the cover then there is an issue beind the cover. Without removing it the task of identifying the source of the issue is impossible. What he may have been doing is giving you the worst case scenario without saying it.

    It depends on how you look at it on wether its a gimmick or not. Yes they do work but not to the level of exspectation that most people buying would want. Its meant for a very minor leak. In your case i would say its cheaper then the repair so why not give it a shot.

    As far as it being a cam seal sure its a possibility but it could be the oil seal for the crank shaft or main front oil seal. Depending on the engine setup it could even be the valve cover seal. Im not going to pretend i remember every engine set up i come across.Some of the seals are fairly easy to replace once you remove everything from the front of the engine but when you get into seals that require removing the timing belt it becomes more complicated. Not putting it back in precise time will result in a non functioning engine.

    I would say try the stop leak. If it does not fix the problem to your satisfaction then you need to replace which ever seal has gone bad. You level of automotive knowledge will have to be the judge on wether you fix it or your mechanic does.

    Just remember never sign the line of the waiver that says you do not want an estimate. Where i live and not all states are the same shops are required to give written estimates but they can have you sign the line that says you do not want one. By signing the line that says you do means they now have to call you before they do anything extra because the price has to be within 10% of what you were told or you dont have to pay for any additionals.

Oil pressure sensor replaced 9/14/2015started to leak oil again. Valve cover gasket replaced 1/6/2016 9/14/2015 now leaking oil again

When you replace the rocker cover gaskets, clean the surfaces where the gasket contacts the heads and the rocker cover with alcohol and a rag. Make sure there is absolutely no oil residue on either surface. Use a silicon sealer and spread it on the side of the gasket that will touch the head. Position it and use the head bolts temporarily as guide pins to hold the gasket in place until the sealant dries COMPLETELY. Remove the bolts. Now put more sealant on the surface of the rocker cover and install the cover on the gasket gently so as not to disturb the gasket. Install the cover bolts and tighten firmly but not so as to squeeze or deform the gasket. If dine correctly, the gasket will not leak.

1997 camry ce 1mz v6

Almost certainly it is coming from the rear bank cam cover gasket, for which leak the Camry V6 is notorious. Other common places are the distributor shaft o-ring seal, the crankshaft nose seal (replaceable), and the oil filter adapter bracket (if fitted)

If you get the cam cover gaskets done, specify Toyota parts, as the aftermarket parts don't last, they harden quickly.

Oil leak from cam seal

Check that the cover gasket is in fact still under the cover and hasn't slipped inside when being fitted . Remove the cover and reposition the gasket using an adhesive to hold it in place while refitting

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.

    Oil leak from rocca cover or cam seal

    I don't understand what a rocca cover is, but your two most common oil leak locations are the front cam seal behind the timing belt pulley and the rear cam journal plug in the valve cover.
    For a leak at the front, next time you replace your timing belt, unbolt the pulley, extract the old seal with a sharp hook, and press in a new seal. Be sure that the new seal is pressed in straight, and grease the lips before you press it in. Often, the front crankshaft seal fails about the same time, so replace that one as well while you have the timing belt off.
    For a leak at the rear, reach back there behind the valve cover with solvent on a rag and clean it up nice and dry, then coat the edges of the rubber plug liberally with silicone seal. Allow to dry. Replace the rubber plug next time you have the valve cover off, but use some silicone seal to secure the new one so it stays in place and won't start leaking.
    These cars are prone to valve cover gasket leaks, so expect to replace the valve cover gasket every few years. This is a particular problem if you use synthetic oil.
    Any time you have problems with oil leaks, suspect that the crankcase is pressurizing due to a plugged ventilation system. Check the flame arrestor to make sure it is clean and clear. The flame arrestor is between the legs of the intake manifold, generally in a hard-to-get-at location. Also, blow down the hose below the flame arrestor to make sure that the oil mist separator box on the side of the engine block has not plugged up with sludge.

    Do the timing belt cover on a 1996 camry have a seal or gasket that can leak oil, mine seems to be leaking for around that area. If so how to replace the seal/gasket?

    The timing cover itself does not seal any oil from leaking. It is just a cover to prevent debris from getting into the timing belt and ruining it.

    To find the oil leak you will need to remove the timing cover and inspect the seals behind the cam gear, crank gear, and oil pump drive gear, and the oil pump to block seal. The most common leaks on these are the cam gear.

    Hard to find oil leak.

    yes if the repair was something related to the oil leak,it would be covered by the 12 / 12,000 mile warranty from the dealer... if they performed the work..when taking back to the dealer, ask them to use an engine dye to pinpoint the leak if they cannot see the obvious..theres many possibilities of an oil leak from the back o the cyl head, there is several gaskets that can be leaking, the dye would be the best or looking at it from below o a lift..if they performed the work they shouldnt have a problem looking at it...sometimes just a few pair of eyes helps as well... from different angles.

    Oil leaking from front of motor.

    Being it is a 97 outbac, I believe you have the EJ25 Duel over head cam Boxer motor, Very good motor. If i am correct you have 5 places that most likely could be the leak. THe crank pulley, in center, Or either of the 4 cam shafts. You will have to look for more signs of the leak. If leaking from the cams you will usualy see the oil on the iside of the pulleys them selves. The crank seal on the other hand generally runs down the center of the block.Please be very careful to check your timing marks on your pulleys before you start it, due to the belt posibly slipping from what you had said. The crank has a small hash line that points up to a mark in the block The top pulleys on both sides have a sigle line that points to a notch straight up on the cover and double lines that point straght down at double lines on the lower pulleys. And the lower pulleys also have a single line that point to a notch outward that is on the cover. Hope this helps and have a good day.
