The pan or plug could be leaking, but either of those would leak all the time, not just with the engine running. If you had to replace the cam and crank seals and timing belt you would be in the neighborhood of $500, the job is very labor intensive.
I have had an oil leak on that side for quite awhile. It just seems that after losing the oil cap (most likely from not putting it on correctly), then this more major oil leak got worse as I described. Not sure if the oil cap flying around inside the engine could have done something.
When you say $500, are you talking labor and parts? Thanks for your help.
The leak never been this bad; where a stream of oil is on the pavement and then pouring out when the engine was running at a stop. (All the oil was on the ground). The oil alert was chiming.
I had replaced all the oil from when the oil cap was off (last week). And then, when this started (major leak), I was driving and noticed the engine making the familiar sound of 'time to add oil', I stopped the car, pulled over and added 3 qts.(which I knew something was not right since I had just added a bunch of oil the week before). Then I noticed the stream of oil on the pavement from wherever I had driven. Then, while engine was running, the oil was pouring out (more toward the right side of engine, passenger side).
Also, from driving when this was happening, oil is sprayed up on back of van (bumper, window, liftgate, etc.)
Could this cam shaft seal or crank seal been leaking for quite some time and then suddenly get worse (major leak as described) since I have had the ongoing oil leak whick seemed to have been on that side? Also, would the oil leak be on that side if it was the oil pan or plug?
