Straight up, because I am tired about dealing with my motor/caR.

The other day I noticed an oil spot on the ground under my car, I looked under and saw some oil on the tranny housing. After poping the hood I noticed that there was some oil coming from the front left side of the motor (tranny side) where the head and block meet, trickling down. Concerned I pulled the plugs finding all four were the same. The threads and electrodes were covered in oil. The body of the plug were the wire attaches was completely clean, almost new looking.

Now, I have had blown headgaskets before and the motor did not respond like this. Normally you are able to tell exactly which cylinder failed, but here they all look bad. Also there was no real blue smoke coming out of my tail pipe for the most part. At high rpms there would be some if I got on it real hard but that is normal. My oil pressure has also seemed to have dropped some as well.

Any and all opinions!

 

are u sure the plugs were covered in oil and not carbon/fuel deposits? i would think if there was that much oil on the plugs, you would definitely notice smoke from the exhaust.

 

What is likely is that either the valve cover seals at the spark plug holes are leaking or the o-ring seals a little farther down in the plug hole are leaking. Doesn't take much oil to leak down there and when you pull the plug out, it all dribbles down the threads onto the electrode.

If there's only a little down there, then it won't get the wires all messy.

Hopefully its the simplest fix... Valve cover seals...

 

stock motor or modded?

 

he said that side of the plug is clean though

Did you remember to install the head gasket?

But seriously, when was the last time you had the head off? Are you SURE your plugs are fouled with oil, or just carbon? Can you post a picture?

Any chance it's the valve cover and not the head?

Sounds like a head gasket to me, but I can't imagine all of your cylinders really have oil, I think you're just seeing old/carbon fouled plugs.

Pretty modded.

I was talking with the guy that built my motor and he said that it might be the valve cover spark plug rubber seals. I am gonna try and get a kit today.

And it was definately oil, and not carbon deposits, it was all "oily". I already cleaned them off so picks wont really help.

Now what about the fact that there is a leak between the head and the block? Is that just a coincidental occurance with the fact that the rubber seals are bad? Or is that a head gasket issue as well?

 

could be a head gasket, or possibly a "warped" head. if its really bad, I would probably end up pulling the head. and if I was gonna pull the head, Id send it out to a machine shop to make sure its flat. same goes for the block. assuming that hasnt been done already.

 

well actually it has the head was milled and the block was decked when I rebuilt the motor 2 months ago. everything was checked. and the plugs only have about 3k on them.

 

Sounds like a headgasket to me. Park the caR for a few days and take the head off and check everything out.

Since your head was milled and decked - I think the same

 

well I just spent a couple hours with the car. I pulled the headers off, as well as the tranny brace, checked all the oil pan bolts, cleaned up all the excess oil, so maybe I can have a better idea as to where it is coming from. I also changed the plugs, drove around a little bit, rechecked them and there was no oil on them now. So I have no idea what is going on.

I actually had a head gasket leak after my motor was built too, even though the head was milled and block was decked. I had to get them redone and everything was fine after that.

 

I really hope that that is not the problem, I am really tired of taking the motor out of my car.
