Bad oil leak front main seal in 1986 toyota 4 runner

Just leaking oil really bad all over the engine compartment after I washed it and drove it back home and opened the hood I could see where oil was on the battery and upper radiator hose and was fresh,so I have taken the radiator out and the fan and fan clutch,now here where I am not sure what to do I see 4 bolts on the cam shaft pulley and the center nut I have a puller to remove the harmonic balancer,which from what pictures I have seen the seal is behind that pulley so how do I apply the puller to the pulley to get it off and do I have to replace or do other things as far as gaskets or other parts such as timing cover or oil pump

    the spark seals where leaking oil really bad so I had seals replaced under the rocker shaft now it makes a really loud ticking noise in the upper engine. It's a 96 accord lx model

    Bad oil leak appears to be coming from behind crank pulley. Has 70,000 miles. Can the seal be replaced without dropping the oil pan and Head?

You need to walk the pulley off.You will need three long bolts that match the thread in the balancer.Undo the centre bolt about half way and bolt the puller to the pulley.the centr bolt is used so the puller has something to push on in the centre Once you have wound the puller up and pulls the balancer until its stopped by the centre bolt.Undo the puller so you can unwind the centre bolt some more and repeat until the balancer falls off.Every thing must be evenly bolted,puller must be mounted squarely or you will have real trouble removing it.Unless the seal can be removed and replaced from the outside of the timing cover you should not need to replace anything else.Did you check the oil pressure switch as the amount of oil your talking about doesnt usualy leak that badly from a balancer seal

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 leaking from toyota camry 1992, 1994 model


    You don't say what engine it has. The 4-cyl was a better than the V6 for oil leaks.

    The V6 had oil leaks from

    -rear bank cam cover gasket

    -distributor o-ring seal

    -oil filter bracket o-ring seal

    -crankshaft nose oil seal (less common)

    -rear main bearing oil seal (expensive, just leave it)

    The 4 cyl leaked oil from

    -distributor o-ring seal

    -camshaft cover gasket

    -rear main bearing seal (expensive, leave it)

    I have a huge oil leak in my 98 Toyota Camry It leaks roughly 1 qt of oil for each hour of driving. What would be the cost of repair?


    Need to find out where leak is from. Kinda sounds like a crankshaft main seal, front or rear of engine. Front one is pretty easy to change, but rear main seal leak means you have to drop transmission to get to it. But it could be another seal or gasket. Can you tell about where leak is, from oil spills on ground where parked? Look at engine. Is oil seeming to leak from bottom end or upper engine. May need to wipe or clean it off to see where fresh oil leak develops. A mechanic may need to put it on a car lift to pinpoint the leak. Good luck.

    Im leaking about a quart a day the motor is covere in oil not sure where its comeing from but think its the front seal


    Are you sure it is leaking or burning it. First give the engine a good clean, then run it to see if it is leaking and from where. If it is leaking that amount then it should be easy to see.
    If it is a front seal, I presume you mean the crankshaft, then you will need to remove the crankshaft pulley to get at it.

    My 1986 toyota Mr2 has a horrible synthetic oil leak. i believe its coming from the crankshaft pulley seal. can i take the crankshaft pulley off the engine without removing the engine from the car?


    yes if its in the front but it more like the back one you might just drop the oil pan and do it if you have room to get the iol pan down

    Oil is leaking bad and oil pan gasket has been replaced what else could be leaking really bad like 2 quarts in 50 miles e-mail jimmybumgarner@rocketmail.com


    is the leak visually on the ground, then it seems like you could get under car and wipe a few things and see what leaks, thats a big leak, car would be leaving a smoke screen behind you from getting all over exhaust system. I would have to say, REAR MAIN SEAL BETWEEN MOTOR AND TRANS, OIL FILTER NOT TIGHT, Is oil all over the timing belt? front gasket/seal failure, Oil sending unit, is the light on or pressure gauge work?

    I dont know where the oil pump is on my 89 toyota


    On a 22RE the oil pump is on the timing cover behind the crank pulley/harmonic balancer,it has the crank timing pointer built onto it,generally they don't leak around the pump seal but as Monster80 pointed out they leak from the front main seal wich is installed on the front of the oil pump,pretty common for the 22R/RE to leak around the timing cover gaskets or out the bolt holes on the timing cover also,usually due to uneven tourqe on the bolts,to check the front main seal you need to look at the the crank from the underside right after you've shut the motor down,if the seals bad you'll see oil starting to form a drop on the backside of the pulley or the front of the oil pump housing.

    Front oil seal


    They are right. The sleeve will seal against the crank seal. The ridges are what is letting the seal leak. I install sleeves quite often on older models, the success rate is pretty high.
