Water leaking, overheating

Water is leaking near the oil pan seal and oil filter. can't see beyond that point because the belt and pulleys are there and there is not enough space.

I had a similar leak which was traced to a bolt screwed into the back of the engine block.

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 leaking bad 1997 kia sportage seems to be leaking in the back of engine


Your problem will be on the oil seal, mechanical seal and gasket. This oil seal are located near the pulley of the engine or in the transmission . This seal need to replace when your car getting old. In gasket the best way is to replace the this with new the oil pan and the valve cover or did you check your oil filter maybe the it needed to tighten or need to replace. This is a heavy work it need service personnel to do this job because they going to open the engine. Your can still use your car as long as you monitor the oil level.

Leaking oil on right side of motor.


The crankshaft oils seals are known to leak after approx 100,000 miles. The Harmonic Balancer (fan belt pulley) end of the engine will have lots of oil and road grit around the oil pan, air conditioning compressor, power steering pump and other area in the engine bay due to wind spread. This seal can be replace without removing the engine. Remove the harmonic balancer bolt and use a pulley puller. If the seal mating surface is grooved replace the balancer too or the new seal will fail soon.

The transmission "bell housing" will weep oil and or trans fluid if the rear crankshaft seal or the transmission seal develops a leak. This seal is much larger than the front seal so it lasts longer and need replacing less often. The transmission will need to be removed from the car to reach these seals.

The oil pan is sealed with silicone engine sealant and will dry out and leak also. Sometimes the leak looks like it is the front or rear seal (pulley or transmission end of engine) but it may be the oil pan leaking and dripping into the pressure plate inspection plate or the pulley. The oil pan can be removed and resealed without removing the engine or transmission but it is a little tricky. Dropping the engine's under brace and exhaust pipe is recommended. Additional engine/transmission support is needed to do that.

While you are under the car look near the oil filter. Above and forward (toward the fan belt is forward) and see if there is oil dripping from the oil pressure sending unit wire. It will leak into the electrical connector. Squeeze it and see if oil seeps out. If so replace the sending unit. It looks kind of like a spark plug screwed into the block.

Near the oil filter you will see the power steering pump mounted to the side of the pulley end of the engine and it is over the right CV drive axle and has several hoses connected. One larger hose is a none pressure hose that gravity feeds the pump from the fluid reservoir mounted above it on the passenger side wheel well in the engine bay. This hose eventually leaks and drips power steering fluid everywhere! It is a molded hose from the dealer parts dept. and relatively easy to replace. Messy but do-able.



Now the top side of the engine. The valve cover has a rubber gasket that shrinks over time in that hot engine bay. Take a Phillips head screw driver is see how loose the screws holding it are. Really loose hu? You can tighten them but you should replace it because it shrunk and that makes the screws loose.

You will need some silicone engine sealant each side of the distributor bridge at the driver's side of the cover. Get a manual to make sure you tighten those screws in the correct order.



Distributor "O"ring seal can leak. Two 12MM bolts to remove it and put a new "O"ring on and you are set. Mark the Distributor's position to the bridge bracket BEFORE you loosen those screws. Line it back up to the marks so you don't mess up the timing and reset the timing after is even better.

I have a 1999 Chrysler 300m 3.5 that is leaking oil. There is no obvious source from the engine, though it is possible. The car overheated last year and I had the dealer replace water pump and timing...


CK- Try a set of Valve Cover Gaskets. It cannot leak from the front cover area because it is where the timing belt rides and there is no entrance into the engine EXCEPT the front CAM SEAL... Remove the cover and look toward that seal behind the cam sprocket. If so it is also leaking down into the front cover and beyond. But look at the Valve cover gasket first, since you mention that source.

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.

1998 olds Aurora i have an oil leak, is it common


There are common places, you'll just have to look around to see where the leak is:
Around the oil filter and the housing
Around the oil pan and the pan gasket
The oil seal behind the damper pulley
Valve cover gaskets
These are the most common places, leaks can spring up anywhere.

I have a 90 accord ex and it is leaking oil from some where and i don't know what to do i replaced the oil pan gasket and still am having the promble


Could be the cam seal (near the cam gear noticeable under the upper plastic timing cover). Or the back of the valve cover gasket, or the main seals (either on the flywheel,flex plate side, or the main pulley side). Could be an oil cooler hose near your oil filter or that the filter is not tight enough.

Oil leak


If you did not have a leak there before you had the work done and you do now, the shop needs to correct the problem. There is no reason why you should need to repair the repair. If they don't see if your dmv has a repair complaint division,,,many states do. As far as a new pan goes, have someone explain what exactly happened to your not leaking pan that warrants a replacement now. (I'd love to hear that answer!) Have another shop take a look and save receipts you will need to present them if you take this further!
good luck

Transmission leak!!


Had similar problem (Jetta 5 cylinder 2006) - leaks in the timing chain cover, large oil leak near the tranny (sounds like your problem), leak from "ALT belt side crank pulley seal and leak from oil pan. This car has only 23,000 kilometers about 14,000 miles on it!!! The dealer repaired this at no charge...
