** Oil Leak** (FOUND WITH PICS) (2nd leak same area) 7/28/2016
*** Oil leak found*** I have a had an oil leak since i bought my evo. I cleaned up the oil that has been leaking from the top of my engine all the way down the back of the engine, near the head gasket, under the timing cover soaking the lower oil pump cover, and eventually down to the oil filter housing. I would get about 6-10 drips a night.
Culprit is the small aluminum drain tube from the spark galley to the outside of the valve cover. * See picture. Now here is the funny part, its not coming from inside the tube like it is cracked, its coming from (AROUND) the tube. I ended up removing the valve cover and taking out the tube. It is not cracked, so i added permatex Right Stuff to both ends to seal it. Lets see if this works. This leak was able to be seen with the engine running in 15 seconds. So it was pretty interesting.
Has anyone seen this before?

Okay so one leak has been found, the other is is the same exact area, if you look to the left of the injector on on cylinder #1, there si a little (yellow/brown oil puddle) I can't seem to find where it is coming from. Oil cap is new, valve cover gasket is new, and re-torqued along with permatex used around cam caps etc.
By any chance are there is area that oil can come out from milling, I.E NPT fitting around that area?

I pulled the intake manifold off the car last night. I really hate knowing the entire back of my block was soaked in oil. It is all cleaned now and I am about to put everything back together. I also decided to go out and buy engine dye, UV light pen, and the yellow glasses to help find the leak quicker.
I may be leaning towards the HG in the back where the oil returns to the block area since the head's hole is about twice as large as the block's oil return hole. I guess it is a common area.
I will post more pictures later.

Hey OP how much oil were you losing from this leak?
I may pull my vc and just seal around that area for good measure but Im skeptical that this is my issue just because it seems like Im loosing way too much oil for it so be from that.
I started this thread years ago and have numerous pics throughout it: https://www.evolutionm.net/forums/ev...fold-help.html
The one picture that makes me think this could be related is right here

I just pulled back up this thread and saw your most recent post and see you are still losing oil and suspect its the HG. I'd be curious as to what you find with that. I did the dye a couple years ago and came up with nothing bc there was oil everywhere haha! I struggled to pinpoint the actual source. Maybe I suck but my oil leak has literally kept me up at night for years now.
FWIW I don't thing its your HG. Although I can't offer any feedback other than that I just don't think it's your HG. I pulled my head last season (well maybe 2 years ago I cant remember) seems like Im always pulling the thing apart and Im still losing oil.
Im curious though how much oil are you losing? Drips on the ground? Noticeable on the dipstick?

I ended up looking. it appear it is the Alternator stud at the bottom, it connect into the side of the block and through the oil pump case. It looks like a little oil is coming out of there. Main leak was at the top pictured.
