I was working on my car a few days ago and I noticed this dark slime around my engine... I'm not really sure what it is but I will post pictures here and I hope somebody can help me out and possibly tell me what caused it thanks !


On the bolt and to the right of it




As you can see its on the bolt...

 

looks like hard/old oil..

 

Looks like you need a front valve cover gasket. I haven't done the job myself because I don't need to yet, but fr what I understand, it's pretty easy. If it bothers you that much, take it off, use a brush attachment on your drill to clean it up, and replace the gasket.

 

If you wipe it off you will see it is part of the head. It might have been made that way for a gasket long ago. It came that way from the factory. Clean it off with brake cleaner or something else and you will see that it is metal.

Here is a link where you can get a closer look.

It could be coolant leaking from the o-rings seal on your rusty coolant pipes.

 

Asand1might be right. I see matching rust areas on the pipe, and right below it. The other mess is on the valve cover.

You might need to replace that pipe.

Are you slowly adding coolant by chance?

 

Yeah I was adding coolant every couple days because the water pump in my car went bad and it was like that for a couple months, but after that got fixed I seem to have no coolant leaks

 

I wouldn't worry about it. It's just built up carbon/oil

 

Same ugly issue on mine as well. It builds up quick and you don't realize.
