Question about 1998 Toyota Camry

1 Answer

Developed oil leak below oil filter where block mounts to upper sump section!!

V6 3 L has developed a rather serious oil leak that appears to be comming from either a upper secondary sump section that seals to the lower engine block.
Have checked lower sump and this appears dry and tight.
The leak CAN BE SEEN SEEPING when motor is turned off
It appears the seal is a silicon one from guys at auto one/ but how hard is it to redo the seal and will the motor need to be removed to fix the seal/ anyother way around this?

This is a real big problem with these cars! I have had the engine apart TWICE and it still leaks!

My guess is that the Aluminum parts are Warped and no matter how much sealant you use... it's going to leak. I used oil dye too and though I can see when it's coming from..the leak just won't seal!


I own a garage in CA

So, unless you have mad skills take it in..it's not going to be cheap to fix and it might not stay fixed for long. we have gotten it to leak less but never to stop %100.

2003 Durango with 5.9 serious oil leak just started below the exhaust manifold on the right side. It did not leak before and haven't had any work done such as oil change to cause problem. Upper control arm...


Check the oil filter and make sure there is only 1 gasket because these motors are known for the old gasket to stick to the engine.So when you put the new oil filter on it will leak badly.

I have a 2012 Kia Sedona van and the oil light is coming on at 1.5 rpms


Various things can cause this, not all serious. In a 2012 vehicle we can almost rule out worn big end bearings as a cause.

First ensure the oil level is correct on the dipstick. Some people also recommend changing the oil filter as they often have a bypass valve in them which can stick open. I personally don't think that will be the cause.

If oil is OK, have a mechanic remove the oil pressure sensor unit and replace it with a pressure gauge. This will tell you if the sender is faulty.

If the gauge reads too low the next thing to check is the oil pump over-pressure relief valve which may have stuck open. Also the oil pump itself may have developed a fault, although they are generally very reliable. The sump pan may have to come off for that.

Oil leak and a Cylinder 1 misfire.


Nothing to do with fuel chemistry

As long as ANY light is on you have a problem

My pickup has developed a leak between the block and the oil filter housing unit, not the filter. Is there a gasket that needs to be replaced?


I do believe that there is actually a gasket that is between the oil filter housing assembly and the engine block. If it is anything like the Nissans, they do have a tendancy to start leaking over time.

Hope this helps..

How do I change my oil on my 98 ford escort zx2


Try this.

On level ground, jack up the front of the car and support it with axle stands.

Get an open container that will take more than 5 ltrs.

Under the engine block you will find the sump.

On the sump you should find a 13mm nut, this is the drain plug.

Undo the drain plug and have the empty container directly below the sump plug.

Retain the sump plug and clean it with a rag.

When the oil has drained out of the sump, put back the plug making sure the washer is in good condition and the plug is tight.

Now unscrew the oil filter having the old oil container below the filter housing to catch any oil.

Wipe around the the filter housing to remove any and all old oil.

Now offer up the new oil filter but do not tighten.

If the new filter fits the oil filter housing, then remove it and lightly oil the rubber seal on the filter with clean oil.

Now refit the filter and tighten it up. Not too tight, you can do this by hand but get it as tight as you can.

Now lower the car to to the ground.

At the top of the engine you will find an oil filler cap. Undo this cap.

Now put in the new oil to just below the full mark on the dip stick. Let the oil drain through the engine to the sump for a couple of minutes before checking the oil level.

If the level is between 1/2 and full, replace the filler cap and start the engine.

Now look at the oil filter and the sump plug for any leaks. Also check around the oil filler cap for oil leaks and spillage.

With the engine turned off. Clean any oil spillages and tighten up the oil filter, sump and oil filler cap as required.

Now leave the oil to drain back to the sump for a few minutes.

Check the oil level and top up as required.

I find that it is best to top the oil up to just below the Max mark.

This should solve the problem.

Oil leaks from the oil filter adapter


If it is not the suggested gasket that is leaking then it is the oil pressure switch located exactly above the oil filter adapter. The black plastic housing could have developed a crack and oil will ooze downward and drip off the bottom of the adapter. I had this problem and changing the oil pressure switch took care of it.

1994 camry oil leak


Hi Toyota Ed
The silver plate seems to be a blank as there are no oil pipes running into.
The leak seems to be weeping along a secondary sump if that makes sense.
If looking from the bottom you have a black sump that bolts onto a silver alloy cast that then seems to be bolted to the lower engine block this seems to have a flexi seal of sealant ( can feel it where it has seeped out) this is were i think the leak is comming from.
Especially when you stop the motor you can see it seeping out around here, but as you know oil sometimes can travel in weird ways and i will check again around the blank plate that you mentioned.
Would i be able to repair it if it is the main sump/ gasket and do you have to remove the motor?

Oil leaking on front right side of the car near oil pan and oil filter


You need to clean the engine and then run the vehicle while watching the area. The most common failure is the oil sending unit located near the oil filter. I have also seen a leak develop between the oil pump housing, which is mounted directly behind the hamonic balencer and the engine block.

Oil Leak from oil filter housing


Seems to be a common problem.
there are two "O" rings a small one inside, and a larger one in a shallow groove where the housing mates to the block.
Would be an easy fix, except for the fact that one nut is almost impossible to remove unless the engine mount is removed.
My 2002 Kia Sportage developed the same problem, which I originally thought was because the oil filter was not tight.
it is a poor design, as the original O ring should have been made so it stayed more flexible IMO.
