SOME Chystler products & PROBABLY others (older vehicles) have water jsckets that run through the timing Cover,SOMETIMES if the cover get a hole in the cover INTERNALLY -(IT) will fill the Engine with oil & ruin the Engine.
it could be a head gasket or water pump or a freeze plug leaking
Check to be sure it isn't the water pump.
Maybe but i think they have a timing chain. but i could be wrong. i could be pushrod. lust take the valve cover off the to of the wngine and look. and yes it does have a waterpump.
1. Check out the water pump 2. check Timing cover gaskets
There are 7 bolts going into the water pump, 4 long and 3 short. The short bolts will go into the 12:00, 5:00, and 7:00 O'clock positions. Look for those 3 (short bolt) positions to have the timing chain cover threaded. The timing chain cover for the 4 long bolts will be smooth. Glad I could help.
(belt) if it needs replacing do water pump at the same time it runs off the timing belt save time and money
timing chain is inside the timing chain cover which is located between block and water pump. the water pump mounts to the front of timing case There is a cover that is behind the water pump... The timing chain is under that cover.
next to the timing chain you will find it in the cover on front of engine where the water pump is mounted they call it the timing chain cover you will have to remove this cover to get at it
It can get in through the timing cover. That does car does not have a "timing belt" cover, but it has a "timing chain cover." There is a BIG difference, as a timing belt cover does not have coolant and oil running through it, but a timing chain cover does have both coolant and oil running through it.
Timing chain cover is where the water pump hooks to on the very front of the engine block.
The time chain is located under the timing chain cover, which is behind the fan and under the water pump.
timing chain cover
Behind the timing cover, which is the large aluminium part that cover the front of the engine. The water pump, bolts to the center of the timing cover.
it is under the timing chain cover located to left of the water pump if you are facing the engine. locate you fan and your fan is coming directly out of your timing chain cover if you have a 4.3.
Look down between the water pump and the timing chain cover and you will see it.
A Dodge Durango does not have a timing belt. It has timing chain. If the timing cover chain gasket is leaking it is normal to change it while changing the water pump.
Check to be sure it isn't the water pump.
The timing chain is behind the timing cover which is behind the water pump. To get at it, you'll need to remove everything in front of the cover and loosen the oil pan a little.
