white smoke from the exhaust?? - chuzie - 01-17-2011
One more post for the link to the block tester...

Don't use up all the fluid. I want to test mine just for fun when I get home.

chuzie Wrote:The other thing that concerns me is that it is only happening, so far, under load. I would venture to say, smoke color aside, that a cylinder compression test may be prudent just in case you have a ring going bad. Since you dont have true dual exhaust and cant duplicate the conditions we cant really narrow to which side this may be originating so test all 8. Have you looked at the spark plugs? I have a compression tester at home if you need it but I bet you have one too.
My bets are on head gasket or ring.
i dont have a compression tester

Ok, so it wasn't my last post. I am just brainstorming here so cu me some slack.
To duplicate I suggest locking the hubs and throwing it in 4 low on level ground with maybe a cylinder block in front of the tires to keep you stationary. If that does not produce the smoke unlock the hubs. I just want to try and strain the engine on level ground.
no compression tester? FAIL!!!

I have a theory. I believe you may need to look toward the top end of the motor. On an incline with the engine revving, oil is pumped to the valve covers and cannot drain back through just the rear drains. A little wear on the guides and the seals, and you have smoke.
I'd pull the plugs, a valve cover, do the compression check(for piece of mind), then pull a couple valve springs toward the rear of the engine. With the springs off and the piston at TDC, check for any rock in the valve stem.

Chuck, I posted in Classic too. I watched the video again and that really looks like oil now that I increased the resolution. When you test it tomorrow do two tests. One with the current configuration (no changes) to duplicate the smoke. Then pull the PCV out of the case (not off the vac line) and see if it does it again. I wonder if you will have oil leak out of the PCV hole @ the grommet. Make sure you get that high angle too.

Hope you get it solved. It doesn't take much oil to make a large amount of smoke. The smoke does not smell like antifreeze, right? Wish I had the answer for you. Just remember to unplug the coil before compression testing!!!

hope to do some testing today

Any testing get done? I'm curious to see what this smoke could be!!

That's oil smoke. Not a head gasket. I'm with the incline/valve guide theory. As a former Army Armor officer I've poured a ton of diesel on exhaust manifolds to generate smoke for cover. Kind of fun, actually. Big billowy clouds of smoke. Bad guide at the back of the motor. Don't let that get too bad. The valve could tip, contact the piston, snap off and grenade a motor. Ask me how I know.....

We will be testing this afternoon. More to come. Tim, now I want to pickup a gallon of diesel and have some fun with the headers. Thanks for the idea.
