    assembly lube in oil?

    Just being jumpy about everything--
    Ready to drive off with a virgin rebuild, and my first rebuild, and every little thing worries me.

    my oil is clear, with clouds of pearly white mixed in.
    Could the white be from assembly lube?

    I know it could be coolant, but I can't think where it would come from!
    Just double checking

    And a very slight burning smell is also normal?

    burning smell is fine as long as it goes away after a few days of driving. I'd check for wisps of smoke and see if I could see what was burning. Check the o2 sensor wires and make sure they're not laying on the exhaust (or anything else laying on the exhaust for that matter).

    not sure about the assembly lube stuff since I've never gone there.

      should disintegrate in the oil. pearly white you say? sounds like coolant. Or some kind of moisture.

        Drive it a bit and keep an eye on it. It will either go away or get worse.

          Was the assembly lube you used white? The stuff I've had was either clear or grey and dissolved in oil pretty quick. Keep any eye on the coolant level and see if it goes down any. A burning smell on a fresh engine is 100% normal just make sure it isn't plastic...the gaskets/paint burning off have a pretty unique smell to them.

            words of wisdom.
            Give a man a fish and he will be fed for a day. Teach a man to fish and he will promptly forget that he once did not know, and proceed to call anyone who asks, a n00b and flame them on the boards for being stupid.

              When we put the engine in my friend's drag car for the first time, we thought we had a similar problem. I believe we used Comp break in lube, and there were a few different types of assembly lube in the engine. After running it, and checking the oil, we were fairly certain coolant was getting in somewhere, because the oil was very strangely colored.

              We continued to run it for a few more 20 minute sessions. Then we drained the oil into a clear tub, and let it sit for a couple days, hoping the water and oil might seperate. Never did. Then we poured the oil back into quart containers to find there wasn't quite 5 quarts (some stuck in filter, etc, etc).

              Changed the oil, and ran the car for 2 seasons with oil changes a couple times a season), and never had any issues; no strange coloring, or any cooling/ coolant leak type issues. The only reason we took it out was because of the hole in the number 4 piston.

              Since that engine, we have built a half dozen more, and always seems to note a similar oil color abefore the first oil change. It may be the combination of lubes and maybe some break in material. But either way, the oil color returns to normal after the first change, and we've never had any issues.

              I'm not saying you don't have an issue. I'd watch it, change it after a short time, and see what happens with the new oil. If you're really concerned, a cooling system pressure test might be of value.
