Just finished a trip east to see family and friends. Was a total of
about 5300miles over mostly highway. Some of the highways were pretty
poor condition. Used 1/2 quart of oil, coolant dropped a little bit, I
think it leaks through the front heater valve.

the '90 Mulitvan has about 125K miles with the original engine, although
I installed a 5sp few years ago. The van rides pretty rough on rough
roads, road imperfections coming through like bangs. On smooth roads,
not so bad.

One issue that keeps arising is the oil cooler leaks. I have replaced
and resealed this twice since I first got the van, and all is well for
1-2K miles and then starts leaking and getting progressively worse. Used
the proper gasket, torque, etc. but still leaks after a while. Anyone
else having this issue and any suggestions? The leak is more annoyance
than anything but does tend to make a mess eventually.�  Was surprised at
the (lack of) oil consumption - using Motil 5w-40. I have used other
5W-40 oils and they all seemed about the same.

Safe travels!
