Just put new timing chains on 2002 4,0
First could not get the engine to start. When I pulled the intake to check the cams there was oil in the valley .Not much so I cleaned it up. Checked cams again and I had right side off location ¼ turn.
Reset cam and engine fired right up.
B UT now I have oil filling up under the air intake .I let it run for 5 min and oil ran down the back of the bell housing . I bet I lost over a quart. Where can this oil come from???
