I'm not a mechanic, but have read that the head gaskets sometimes crack and leak oil into the coolant. Maybe a cracked head gasket could leak oil onto the timing chain.
I'm adding a bit here to the answer and I am a mechanic. Generally there is a seal on the cam and if that is leaking you need to replace it. As for the cover, did you put silicon sealer on the curved piece of the gasket, especially the corners (where it goes up over the cam) and also the other end if it has the same curve. Do this on both sides of the gasket at this point. Don't use too much but you need an even film on both sides of the curved bit and more at the corners. These gaskets are famous for leaking at this point and this is how I stop it. If you didn't, just take the cover off, clean up the gasket and cover so no oil and then reinstall.
If it is cam seal you will need to take off the front cam pulley and the chain, loosen the cam very carefully a little at a time on the bolts, and replace the seal. Not a big job either and any good manual will tell you how.
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.
Head gasket, timing cover gasket, or hose leaking.
Failed gasket.
Not to my knowledge...but there is a gasket around the timing cover that will leak antifreez if it goes bad. It is a pain to replace, but it can be done. If you've replaced the water pump and it's still leaking (as was my case), then go one step further and replace the gasket around the timing cover. ***caution*** use a repair manual before attempting this!!! There are ***a lot *** of bolts to undo and some require sealant on them when they are replaced. The manual will tell you which ones to put sealant on. steve phx az
Possible cause is a leaking head gasket or timing chain gasket if the water pump mounts to the timing chain like on a ford 302 cid You probably are leaking into the crankcase through the headgasket. There is a slight possibility that the block is cracked.
I just had the timing cover gasket on my 2000 Ford Taurus replaced...Cost of Repair was $513
It is possible and if it is you have a serious problem. Seek professional help.
Not unless there are other problems with the engine, such as worn rings, leaking head gasket, failing oil pump, or something of that sort. Timing chains and belts wear out after a while, just like tires.

Leaking antifreeze from a timing belt gasket in a 1997 Buick Skylark could be due to a worn or damaged gasket that has failed to maintain a proper seal. Over time, heat and exposure to coolant can degrade the gasket material, leading to leaks. Additionally, if the timing belt is improperly installed or if there is excessive pressure in the cooling system, it can exacerbate the leak. It's important to address this issue promptly to prevent engine overheating and potential damage.
