Oil leak 90 shadow

I have been trying to track down an oil leak for several months. My 2.5l engine has 120,000 mi on it. (1990 dodge shadow)

I love this car, but an oil leak near the front of the engine (timing belt area) gets worse each month. It is now leaking a quart every 300 mi. I have replaced the crankshaft seal and I have re-done the oil pan 4 times.

I get a drip at the bottom of the crankshaft area when the engine is running, but it is hard to tell exaclty where it is comming from because of all the pulleys, timing cover, and belts etc. in the way.

When I go on a trip (highway driving 65-70 MPH) oil leaks at a much higher rate.

Does anyone have any ideas? I have searched the internet and found 2 other posts with similar problems on a 2.5l but there didn't seem to be any solutions.

any suggestions appreciated

camshaft and balance shafts are in there too, a little time consuming but ..... take the timing belt covers off, clean the area good, degreaser, steam clean, etc, leave the covers off, take a two hour trip up and down the local interstate, back home, see where the oil is coming from

Sounds like a good plan. It sure seems like a seal from a moving/rotating part might be the problem, as sustained high speed increases the leak. Thanks for the suggestion.
