oil in #6 spark plug...

[lppro]

ok so i was just changeing out my plugs on my freshley rebuilt 7m (has many other issues) i thought it was just burning oil because its a new motor and the rings havent set yet... well heres what the #6 plug looked like:

all of that oil on my hand came from the plug... im thinking that the idiot that rebuilt my motor got in a hurry and forgot to make shure the piston rings werent lined up on the #6 piston... this sucks... is there a way to tell if in fact the rings are all lined up? maby its valve seals? but the head has been freshley rebuilt... btw theres 385 miles on the motor..

i also just went back out there and took a flash light and looked down into the spark blug hole.. all you can see is oil... so the whole cylinder is full of oil... perfect...

Leaking Cam Cover.

If it were internal the insulator/electrode would be fouled.

but, correct me if im worng if it were a leeking cam cover woundent mt spark plug vally cover and vally be full of oil? how would oil from the cam cover get into the cylinder?

 

[IJ.]

So from the metal part of the plug upwards it was dry?

 

[lppro]

yep....

 

[IJ.]

DOH!

Sorry for my earlier misleading post then......

I'd be VERY concerned if a motor I built did that.

 

[lppro]

what do you think could caus this? am i correct to think that the ring gaps might be lined up?

 

[IJ.]

Even with the gaps in line I wouldn't expect to see that amount of Oil up top

 

[lppro]

what else could it be?

 

[IJ.]

I'm at a loss to even make a guess sorry.

Do a comp test and see if that reveals anything then maybe a leakdown test.

 

[lppro]

whare can i get the tools to do these tests? and i know what a comp, test is but what is a leak down test? sry if thats a noob question... lol

 

[IJ.]

Moroso make a leakdown tester but you'll need a compressor to do the test.

That's why I suggested the Comp test first and see what it reveals.

 

[lppro]

ok well ill go to my local auto parts store tomorow and get a comp. test kit...

I had a #6 plug look the same once. I took it out and it was covered in oil. Put a new plug in and ran it for a few days. When I pulled it back out it was completely dry. No idea what happened. There was no oil between the valve covers.

im hoping for your sake that a ring hasnt grabbed or youll be up for a warranty claim.Luck with the problem

 

[lppro]

omg i have no clue what happened... but i looked into the plug hole before i put the new plugs in.. and it was completley dry! wich makes no sence... but its fine with me.. lol i put the new plugs in and everything back togeather and WOW she has never ran this good.... this was freakin wierd...

I had a similar thing happen to me, it ended up being a faulty valve cover far back near the #6 plug, and as a result of the angle of the motor, the oil just pooled down in the galley near #6


New valve covers and gaskets fixed everything. Hope if anything this gives you and idea!
