What do you guys make of this ?

[sirgerman]

Saturn sl1 2001 , 94000 miles , burn oil so therefore , I use a mix(50/50) of 15w40 diesel oil with 10/30 PYB

Far better than any Saturn S-Series engine I am used to seeing. That may be a combination of your careful choice of oil, and because many other people who drive those cars treat them poorly.

How come one side is darker than the other ?

Because Saturn engines are like the Moon...

In repsonse to SirGerman:

Because there is air circulation on the right side of this picture due to the PCV system. The right half should be slightly cooler and have less carbonaceous gases under the valve cover.

*****!!!!

 

[oggb]

Looks just dandy.

 

[4D-56]

im no expert, but that looks like a case of "valve cover back on....whats for dinner honey?"

keep doin what yer doin.

 

[bustednutz]

Looks excellent! No need to worry about a single thing. Little oil burning, and use a quality oil to top off. Used a decent filter and button it up. Good to go. Put another 94k on it and enjoy.

 

[sirgerman]

that why I try to use 15w40 diesel oil as much as possible

What's the OCI history?

 

[sirgerman]

I got it whith 84000 miles , and since then every 5000 miles and a oversize filter ,

It's probably just the camera angle or it's on the lobe, but the spring on the exhaust valve on the far left looks funny.

I wish my son's 2000 was that clean. I was expecting some varnish but not the other accumulated crud that I found. I'd put the cover back on and forget it, which I'm hoping to do next time I take it off.

LOL I agree, nothing dirty in those pics. Put it together and worry about something else!

 

[jmsjags]

so do all mineral oils cause varnish like that? i guess it doesn't really hurt anything because no one will be looking under your valve cover, but still..why is it that synthetics don't cause varnish?

 

[sirgerman]

you should try 15w40 during the summer or a mix with 15w40, it may help in your case

No not all mineral oils cause varnish, and there can be varnish from synthetic oils, too. That's the short answer, at least.

 

[A_Harman]

Looks pretty good under the valve cover.

Why not run some kind of 10w40 High Mileage oil, instead of doing a mix?
