Puzzled on oil leak
Puzzled on oil leak
So i have an oil leak it seems from the back of my Engine Head. I have been searching for this leak for a few weeks, i got new oil cooler and lines, resealed my oil pan and that didn't help. I am now feeling behind my engine and feel oil along that pipe that runs behind and underneath the intake manifold. So from searching on here i am seeing it is either valve seals or my Head Gasket. Think i can rule out head gasket but someone can tell me otherwise, as when i run the car there is no white or any different color coming from the exhaust, so there is no coolant mixing, am i right ?
If its the valve seals or head gasket i think i am just going to wait and build my engine. This is an Evolution IX.
Any input is appreciated guys.

The Mivec line is banjo fittings on either end, so those don't leak.
I have found higher mileage cars can start leaking oil from the intake manifold gasket as oil builds up in the manifold and charge pipes from the PCV system. Worth a shot to pull the manidold, charge pipes, and intercooler, clean everything out, and put it back together. I would also do a new valve cover gasket, they're not too expensive and easy enough to do. And with the manifold off the back of the motor you'll have lots of room to hose off the back of the engine with brake clean.
The head gasket generally won't leak oil.

Car has 67k on the Dash but i will definitely try all of that, won't hurt to try and i will get to clean my engine bay. Its a small leak when idling but when i put some gas on it, it starts to flow a bit more. Will report back, i will try and start this today.
Oh, this is an actual dripping leak... Never mind on the intake manifold lol. Thats usually just like seepage, enough to make a mess. But it never really drips..
I would check the mivec line out. One of the banjos may have come loose. Or maybe the oring on the mivec solenoid is leaking.

Haven't had my head off, so in looking i am going to go with @letsgetthisdone suggestion and going to order some new gaskets and line, maybe the whole thing or upgrade to the MAP mivec line.

How would i change the boring on the Move solenoid, is it as simple as taking out the Mivec Solenoid and replacing the O-ring. I recently got all new Banjos and washers for the Mivec feed line and started her up and oil was still coming out faster than i can type this passage.

Is the valve cover leaking from the little moisture drain tube that goes into the spark plug valley?
No leakage from moisture drain tube, just that back area, any idea on the size of O-RING, now that i do some reading on here i wonder if when i installed my ported intake manifold, i wonder if i bumped the mivec solenoid.
