Hey guys,

I am having oil sipping out from my exhaust manifold flange where it bolt onto the head. Any idea where that might be coming from?

 

bad exhaust manifold gasket.

 

Could be a couple of things, check your valve cover gasket and your head gasket. It can also be that you blew your exhaust valve seals. Also check your oil feed line from the head to the top of the turbo (this is for stock turbo set up, might apply for some aftermarket set ups).

 

The only place i can think of is the exhaust valves seal.

 

How much is it, a lot or a little? Could be road grime. I have what looks like oil around the edge of the header at the gasket. I think that its stuff that I have picked up from the road though.

 

its def oil...not dirt

I have took some pictures...tell me what u think?

 

Well sorry to say, but that definitely looks like your valve seals. If so, you'll have to pull the head to get them fixed. Are you blowing blue smoke out your exhaust? Have you had to add any oil recently? When did you notice leak?

 

There no smoke or not really losing any oil. The head has been tear apart by mitsu twice for other probs.

 

Have you cleaned it off? I would now that you have pics. If it doesn't reappear then the mech might have spilled some oil there and it is just burning off slowly. Otherwise its rings, or valve seals. The mech might have screwed either one of the tow up as well.... Bummer. Good thing that Mitsus are the best backed cars in the world

 

Ya, I cleaned it off yesterday and the picture was taken 1hr ago after work.

 

how does the oil make it outside the engine like that? Why wouldn't the oil burn off?

 

It is definantly your valve seals man. I had the same problem with my evo. I checked the gasket and put a new one on but that didn't solve the problem. So then i checked oil seals and they were all messed up! Got new ones, and now look at me!

 

Valve seal issues? Hmmm...do any of you guys have bigger cams? This reminds me of the "Any damage to stock valvetrain" thread.

 

I have the HKS 272i 262e cams. I still do not understand how the oil would get out like that though.

 

There is an oil passage behind one of the studs for the exhaust manifold. Im sure it is leaking and thats all. Its a very common problem on DSMs. Have you removed the manifold before? I would just remove the manifold, replace the gasket, tighten the hell out of all the studs and put it all back together. Im sure its nothing terrible if your not blowing a ton of smoke out the back.
