I got smoke comming from under my hood near the engine block on the right (diver side) of the intake. You know, where the exhaust pipe meets. It's a '76 GMC 350 and 350 tanny.
It just started this! I think it is oil, but I ain't no mechanic! But, I do need help!!
-
Top of the engine of bottom? Is it leaking any oil near the filter? Are the valve covers on snug and not leaking?
-
Bottom! It is near the filter but not directly from the filter! I did changed the oil 2 weeks ago. I'll check the valve covers.
The smoke is comming from the area right under where the last spark plug is on the right (driver side)(V8)!
-
Are u sure u didnt get some oil on your exhaust pipes??
-
Positive. I clean the whole area when I do an oil change!
I even let it run for about 45 mins. after i did the oil change to see if any thing was leaking!! I didn't smell any oil or see any oil anywhere.
Yesterday, I just back out my drive way and smelled oil in the cab, stopped, left it running, raised the hood and saw a little smoke rolling from under the engine block near the last spark plug on the right(driver) side of the block. Turned the engine off and the smoke kept comming.
When it cooled I notice some oil looking substance near the block! I looked on the other side and say transmission fluid dripping on the ground. This was on the opposit side of the block! But no smoke from there!!
Help!! Please!!

-
What has changed since this started? Can you not tell where the source of the smoke is?

Oil pressure is 60 (or high as it goes). I can get pictures posted today or tomorrow!What has changed since this started? Can you not tell where the source of the smoke is?
There are no changes that i am aware of since this started, but what do I know? She cranks sounds good and strong, just has a little smoke. The source of the smoke, I will crawl under her to see if I can see anything!

Have you rerouted the pcv system, or is the pcv valve clogged? or the ventelator from the valve cover. These could increase crankcase pressure and make thing leak, something to think about if this started suddenly. Or could be just time to change gaskets.

No, I have not rerouted the pcv system. heck, I don't even know what a pcv system is! ???
How will I know if it's time to change gaskets? The engine was just rebuilt in late '06 or early '07? The gaskets should not be leaking this soon...should it?
-
degrease your engine. Then pinpoint the leak. If you can't pinpoint the source of the leak use dye tracer and a UV light.

Thanks!! ;D
