Pic of valve cover area on Havoline

[Gary Allan]

Vad ..that's not a clean view there ..that's a pristine view. I didn't even have it look that good when it was an engine on M1 that never saw anything less then 300 miles a day. It still had a clean, yet "bronzed", appearance. That looks brand new

 

[vad]

Yea, yea.
I've been accused before already in falsifying the record in presenting a picture of a brand new engine.

If OriginlHacker decides to come over to open up his valve cover, then I will have a witness to support my claim.

The varnishing is not just a stain. It is a deposit of finite thickness that is a real threat to the engine parts, gaskets and seals. If I see it in my engines, I consider it to be an oiling failure on my part.

The synthetic oils and HDEO's have always done an excellent job on keeping the engine clean with the proper OCI. You should see white metal regardless of the mileage if the oil is correct for the engine.

I agree. it's stuff like this that makes me glad I now use Havoline 5w30.

I was curious, for comparison, what a badly sludged engine looks like. I did some Google Image Searching and

man, what a nightmare. I had no idea. I don't necessarily buy the 3K OCI but after seeing some pics of sludged up engines, I might go back!

I think it was more like 17,000 miles not 7,000 miles as stated.

That picture takes the cake! Has the oil EVER been changed?? Wow, and I thought I had seen it all.

You are partially correct. Yes, varnish forms as a resinous layer on surfaces exposed to fuel vapors.

Staining is due to exposure to heat and various components in the oil, which may be additives or the various combustion byproducts, acids, fuel components etc.

Keep in mind, the engine pictured in this thread has seen approximately 8000 hrs of operation and it is perfectly normal for some discoloration to occur. No failures on anyone's part.


Per the Noria site, the definition of Varnish -

When applied to lubrication, a thin, insoluble, nonwipeable film deposit occurring on interior parts, resulting from the oxidation and polymerization of fuels and lubricants. Can cause sticking and malfunction of close-clearance moving parts. Similar to, but softer, than lacquer.


And a good explanation of varnish in this Question of the Day Thread by Molakule.

Just a quick question here, vad. Is Redline "clear"? Now my Agip PC synthetic is virtually clear as water. It's almost impossible to see on the stick. If this is the case with RL ..cool ...


..but...I've never seen a head with the valve cover off that shows NO OIL if its been run. Just a hint of that high polar attraction stuff.

lil help

I don't fully agree. I've seen stainless steel forever discolored due to how pourous the metal may be. Sure there may be films that adhere (that's what they're supposed to do) and never get resuspended in future film formations ..but I've seen stains that highly resist removal short of a resurfacing.

Vad...Zetec?

 

[Rodbuckler]

The varnish actually wipes right off with ammonia solution or a caustic solution. I have only ever seen bare metal beneath it.

It started to sip some oil through, just enough to get the surrounding area a little wet.


Could that leakage be a result of synthetic usage?

It is amazing. Not even a speck of dirt on the outside or anything in the spark plug recesses...
