Hi guys, new to forums (well, not new, been lurking since 09) but not new to toyotas, well without further due,

Oil leak, and I dont even know where its coming from, its not coming from the front crank seal, or the valve cover, cause those part are dry,Its coming from underneath the manifold, and I washed the engine 2 times and it just ends up looking the same, so im lost on this one

don't know how to post pics from mobile,so help on that would be appeciated as well

Which manifold? Intake or exhaust? There are oil veins for the oil pressure gauge under the intake or passenger side of the engine. Oil filter too.

What type of vehicle we talking about?

1990 pickup 22r (carb'd), intake side

Hard to tell without pics. But like I said three options oil pressure unit, other oil vein connector in between the motor mount bolts, and the timing chain cover/pan.

not sure about the 22r but on my 3.0 the oil cooler seal was the culprit after about 2 years of having a leak

Can you tell what else is connected onto the oil veins other than the oil pressure gauge , i tried rewashing the engine and using uv dye but no luck, its just a humungous leak, its not the timing chain cover, cause nothing would come from there as I uv lighted that part

apparently uv light doesn't do any justice in the pics but looking at in in person its pretty useful

Maybe a valve cover leak wash it all down again and run/watch it. Start at the top and work your way down.

Oil filter, oil pressure unit, pan, timing chain cover, valve cover, fuel pump gasket. There is suppose to be a spacer between the pump and the valve cover gasket. There is no other possible source I can think of. It appears to me the oil comes when the engine is at higher rpms.


Be careful, but have it run at 2000 or 3000 while looking for the leak, parked of course.....
