A quart in 200 miles is a lot to lose unless there is a pressure leak.
I had a leak and could not determine where the oil was coming from.
Took a look under the truck a number of time, found what looked like a top of the motor leak, traced it to the Distributor area (’88 2.9L).
Replaced the gasket under that and still had the leak.
Using my findings from the earlier chks, determined it had to be the valve cover gaskets, replaced those, still had the leak, wtf.
Then I finally did the run the engine/under truck oil leak chk (make sure to block the truck as well as the e-brake).
I had the oil chg’d by a local guy who uses Valvoline (always liked that brand) and he replaced the filter and tightened it with one of those bottom of the filter wrenches, (stamped metal version).
Guess what, the wrench had to be a really cheap one because it had cut the filter in three places and it didn’t show until the engine was running. there is was oil leaking out of the lower side of the oil filter, F@@K, how did I miss that.
Replaced the filter, leak was all gone and the guy swore he did not use a wrench to put the filter on, @sshole.
So, chk for leaks with the engine running as “always dirty" said.
