Hello,my 2000 odyssey leaks oil.guy said its front oil seal but im gonna need time belt,water pump,vtec valve and oil pan gasket.Do i really need all that just to change front seal? $400 for labor?


A leaking front seal will allow oil to get into the area where the timing belt is located. This will cause oil to get on the belt and can cause damage. Since the timing cover must be removed to access the front seal, it is recommended to replace the belt while you are in there. Also, the water pump is driven off the timing belt. Replacement of the water pump is always recommended when replacing the timing belt for two reasons. First, it is easily replaced at this time and it is good preventive maintenance. Secondly, the water pump bearing is under tension from the timing belt and develops a wear pattern. Replacement of the belt without replacing the pump will cause the new belt to wear the bearing in a different pattern, often causing leaking in a very short time after the replacement. This would then result in having to repeat all the labor again to replace the pump. It is easy to see that for $400.00 labor, you don't want to do that again in only 2-3 months. as far as the VTEC valve is concerned, I don't see a relationship to the oil leak. It could just be something else the mechanic found during the inspection. I can find nothing in the remove/replace procedures that requires replacement of the oil pan gasket. Again, maybe something additional that is needed from visual inspection, but not needed for the front seal.

Oil leak


If its a twin cam engine just replace both of them. They are cheap enough and if you buy locally you whould be able to return the one you don't need.

Personally I would replace both so you don't have to worry about it in the future.

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.

Leaks gear 90 oil by the throw out bearing on my 1999 ford f350 2 wheel drive dually diesel


The only gear oil near the throw-out bearing would be in the transmission and the only way to the throw-out bearing is out the transmission front bearing retainer. I would check the vent first. It's on the transmission top. If that's free you'll have to remove the transmission and front bearing retainer to check the front bearing and seal.

Camshaft seal? A friend of mine had a truck and it sounds like the same problem. He ended up selling it. They fixed it and drive by his house all of the time.

Leaking oil left side of motor


Since it's not clear whether you mean driver side or passenger side, I will address both.

On the driver side, the most common leak is from the distributor. This can be caused by the distributor shaft exterior o-ring, or it can be caused by the distributor shaft interior bearing seal. To determine which it is, remove the distributor. First detach the spark plug wires, then undo the bolt that holds the distributor to the head, then pull the distributor out of the head. You will see the o-ring on the exterior of the distributor shaft. This is a $0.50 part, so just replace it with a new one as long as you have the distributor out. The bearing seal is on the inside of the distributor. To inspect it, undo the three bolts holding the cap to the distributor body. Pop the rotor off the shaft, the unclip the inside plastic cover. If you see any oil inside the distributor or the distributor cap, this means the seal is leaking and must be replaced. You can get a seal and bearing replacement kit from kbox.ca. Or, you can just buy a new distributor. Note: To get the distributor back in place you must align the shaft correctly with the notch in the camshaft. There is a right way and a wrong way. If the shaft seems to be aligned but does not go in, pull it out and rotate it 180 degrees, then put it back in.

The other possibility on the driver side of the engine is the main seal between the engine and transmission. If this is the case, you would have to either drop the transmission or pull the engine to replace it.

What if the oil is leaking on the passenger side? If it's coming from behind the timing belt cover, there is a camshaft seal and a crankshaft seal, both of which can leak oil. To get to them, you will have to remove all accessory belts and the alternator, remove the exterior crankshaft pulley, remove the engine mount (support the engine) and the timing belt covers, remove the timing belt, then the crankshaft pulley and/or camshaft pulley, whichever is necessary to replace the leaking seal(s).

Where else could oil be leaking from? If it's coming out from near the top of the engine, that's the valve cover gasket. Remove the valve cover and replace the gasket. While you're at it, replace the spark plug tube seals.

If it's coming out from near the bottom of the engine, it could be the oil pan gasket. Remove the oil pan and replace the gasket.

One more possibility for oil leakage: The head gasket. But in this case you would have noticed other symptoms besides just an oil leak.

Good luck! Let us know how it turns out.

My toyota vienta 3VZ-FE 1996 - oil leak onto exhaust


Hi,

That engine will leak oil from

- cam cover gaskets (rear one drips on the exhaust)
- camshaft end seals
- distributor shaft o-ring (appears on top of transaxle housing)
- oil filter bracket to block o-ring seal (drips on front bank exhaust)
- crankshaft nose oil seal (have done with timing belt change)
- rear main seal (expensive, leave it be)
