My dad looked at it and said it was just really gassy....you can smell it when you get close to it....I'll try to post another picture.

I think it's just time after time over the period of 6 months or so of just starting it for people, letting it idle and shutting it down before it gets really warmed up. Having a big honkin cam doesn't help much....I'm sure it's loading up a little bit.

How many miles are on that engine at this point in time? I suspect it is not broken in yet (ie: 5000+ miles or more on it?)

Oh shoot no....I built and dyno'd this time last year. It has not been in a complete car. It may have 3-4 hours of run time on it, but I doubt it. I got some oil in a glass. I'll post a pic here in a minute.

You might want to try a picture with a white background in a clear smooth jar, glass. I can't see squat in that one.

That oil looks very discoloured from blow-by gasses. Not surprising considering the age of your engine, and the fact that it has seen no road miles yet.

Mobil 1 - is that a synthetic?

My info is that break-in with a synthetic is not a good idea - stops the rings from sealing. Do 5000 miles with dinosaur juice before you put synthetic in there. Then you know the rings are fully bedded, and they won't, virtually ever, with a synthetic.

JMHO of course, and what do I know about US engines????

Why the oil is green I do not know, long periods with the engine idling qualifies as "severe usage" in most new car manuals.

I have been told flat out by the builder of my engine, (and have read the break in directions supplied with several crate engines),

"Do not use synthetic oil untill at least 2500 miles or the oil consumption has stabilized."

If you go to www.Mobil1.com they describe their synthetic oils and suggest they are ok for breaking in NEW, as in recently manufactured, automobile engines by the major manufacturers.

I would guess that a modern, mass produced high quality engine has a "ring, piston and cylinder finish package" VERY specifically designed for minimum break in time and long life to meet emissions requirements from the git-go and then for 5 years+.

Opionions of professional high performance engine re-builders opinions would be great here...guys?...but it seems to me the rings, cylinder finishes, etc generally used on hi-performance rebuilds are an older technology, perfectly adapted to the application, but still requiring a ring break in period on standard mineral oil...chrome rings taking the longest to seat, and iron rings less, and the stuff in between, steel, moly-filled, whatever, I dunno.

I would change out your synthetic oil for a good mineral oil, stop idling the engine to show off to the gang, finish the car and start driving it with a heavy foot in the intermediate gears, avoiding approaching red line, but get on it hard without pinging till the rings seat...take your friends along for the ride.

Have fun.

It's not synthetic guys....Mobil 1 makes a synthetic oil which I use in my Mustang and such....but this oil that I've put in this engine is regular dinosaur oil....nothing synthetic about it. That's what I've always put in it, and had planned to do so until the engine was broken in.

i don't think i would worry about it now, but for some extra insurance, so to speak, you can get one of those oil analysis kits at most auto parts stores, and send it in, and see what it says.

I have done it occasionally in my cars. Never found anything i needed to worry about.

Dang, Let's talk about that pink thong you mentioned a few post ago.

Is this something you feel strong about?

Do we have to see you in the thong, or are you going to just photo the thong?

What ever you do, don't do a smear test with the thong.

Just change the cotton-pickin oil.

And laugh.
