Oil coated spark plugs and metal
 

'88 928 s4 auto

OK, so I've done more work on my car and pulled a few plugs , so here are some pics. There were flakes of metal along with oil. Because there is so much oil I'm thinking the piston rings are shot, or as a friend suggested the car sat for so long and possibly the oil leaked passed the rings?

Here's my previous thread that has a little bit of history on the car.

Repost of my last post from the original thread:

On the surface, this sounds serious.

Could you find a way to repost the pictures? The links don't seem to be working correctly.

Linkies no workie here, but I think those are the same pic's that you included links to at the end of your previous thread??

Looking at the high-water mark on the socket, I am thinking that the oil was above the spark plug, in the bottom of the spark-plug well in the head-- and not in the cylinder itself. The upper part of that well is formed by the cam cover, the lower part is in the head--- with a fat o-ring between that likes to get old and brittle. That allows oil to leak from the cam housing into the spark-plug wells.

That doesn't explain the metal (which I am not seeing in this picture), but that could just be dirt, corrosion and paint flakes from the outside world and not the inside. Unfortunately pulling the plugs before draining the well let all that crap into the cylinders. Flaking paint is no big deal, sand would be.

Unless the car was stored upside down, I wouldn't recommend soliciting futher advice from this particular friend. Oil tends to leak downwards...

What's the stick-thing shown in this picture?

Jim... I think he used the stick to see if there was oil in the cylinder (?) but that could be from the cam cover as well. Not so good if it introduced foreign (non-Porsche) material into the cylinder.... :(

KpAtch3s, is this the metal you mentioned? (This is your DSCN1226 picture from photobucket).
Flake of something at the edge of the socket, some smaller stuff at the end of the threads.

It looks more like paint flakes to me. Is there any corrosion or flaking paint on the inside of those spark-plug wells?

If the plugs are still out, be very careful about anything dropping into those holes.

That makes sense, and looks like oil wiped along the side but not immersed- which would be consistent with oil in the plug wells.
If it is just leaking oil and flaking paint then it should be OK-- that assumes the plug-connectors were in good shape and kept everything else out of there... :icon107:

Mine had major bodies pf oil in the plug galleys. It ended up just being oil seeped passed the valve cover gasket from sitting so long

looks like peeled paint and oil coming from cam cover

Same. O-rings in valve covers leak oil on top of plugs.

Only mistake here was pulling the sparkplugs before soaking up the oil that collected above them.

Messed up my shopvac hose, but I duct taped small diam hoses on the end of the hose and stuck them into the holes to suck stuff out.

No need to intoduce dirt or worse into cylinders... if it can be helped.
