Holy Mother Of Valve Deposit


Recommended Posts

I will have to add a picture later to accompany this, but my description may suffice for most. Now, I went to the parts store and happened to get a valve cover gasket while I was there, since mine has been leaking a bit. Got back to the house to change it and took the cover off. What I'm looking at looks like a jumbled mess of mud stuck everywhere under it. I literally, I mean LITERALLY, have inches of burned up oil crowding everything under the valve cover. It looks like a disaster in there. I don't know what this may mean, or how to clean it, any suggestions?

Mostly it means the previous owner(s) probably never changed the oil, and did a lot of low-speed, local driving.

 

Start cleaning with a narrow putty knife and a shop vacuum. You need to keep the vacuum running so whatever you scrape loose gets sucked up rather than fall into the oil passages.

 

Or ... pull the head and send it to a shop to be hot tanked.

Here is a reference for it. I ended up just scraping it off with a shop vac handy. Any time something fell into the channels, I used my fingers to narrow the air flow and sucked it all out. It's amazing what people are too lazy to do on vehicles nowadays.
