engine uses a lot of oil ..1qt every 150 miles....it is a 2.3 with the dohc

What is your question?

engine sometimes runs like new and then just doesn't seem right...chiga chiga sound when idleing..take off oil cap and much air out of cap..engine only has 193000 miles on it I had a 97 ranger with 237000 and didn't use a drop of oil..i don't think the 2.3 I have now is as good a engine as the one in the 97..whhat do you think
