Lay carboard down to catch oil to see where is dropping from and color.As the subject says...
2008 Mazda CX9 Burning Smell with smoke from under hood... started out of nowhere... ironically after we had ourselves a cold spell come through here so not sure if that is any indication or important fact... smells like burning oil, there are drops of oil under the car but I can't see where it could be coming from. I do not see any bubbling or anything in the reservoir, I don't see smoke from exhaust pipe, I'm not overheating (thankfully)... so asking if there are any certain things I can check. Was on my way to church when it started, turned around and went home to not take a chance on Christmas Eve... today... didn't wanna spend it on the side of the road with family. I plan on taking it somewhere to get looked at but who knows what they may come up with or make up... so hoping for a heads up or something I can check out myself. Thanks in advance.
Thats alot of oil.Brownish
Most recent repair was replaced oil pan but that was almost a year ago and have had no issues along the way. We drive just around town or highway so no offroading...

More than likely it's an oil pan gasket fail...which would leak all night with vehicle off.Was good on all fluids bit after seeing this, was half quart low on oil...
In old days we used to replace the gaskets and seals... a real PITA.I know many people feel there is no quick fix for leaking seals. I HAVE used Blue Devil in cars in the past, however I am curious if anyone else has and how did that turn out?
I think they're all the same and probably use alot of similar ingredients, maybe slightly different formulas.here's what I'm gonna try to do tomorrow... thing smokes way too bad to go down the road...
change oil with slightly thicker fully synthetic oil... thinking 5w30, then also add a bottle of Bar's Leaks Rear Main Sealer, then hope for the best.
Feedback encouraged and appreciated...
If you could, how old are your mazda's with leaking seals??Am having the same issue this week after some extreme cold night in georgia. I've just replace the valve cover gasket but it's still leaking ..its coming from behind the rear exhaust manifold.i don't see anything running down from the top so far
Thanks. Good to know the seals are lasting long on the mazdas.2008 Mazda CX9
2007 cx9 with 200k on it. I've never replace any gasket until now. Not even the water pump as yet.i may have the remove the cat,if the bolts aren't frozenIf you could, how old are your mazda's with leaking seals??
Just asking beacuse I've had an older Toyota engine that didnt need valve cover gasket til it's 9th year. More recent Toyota and Ford engines both lasted for about 12-13 years before very minor seepage and only needed Valvoline high mileage oil to recondition the seals.
Maybe you should try some valvo high mileage or some blue devil or other seal additive.
Unless your keeping it for several more years(or waiting for it to be a classic), just do next oil change with Valvoline high mileage, or another seal conditioner additive. It should seal it up for a few more years.2007 cx9 with 200k on it. I've never replace any gasket until now. Not even the water pump as yet.i may have the remove the cat,if the bolts aren't frozen
I don't want to take that chance because it's getting on the exhaust manifold. I prefer to just fix it ,once I figure out the issueUnless your keeping it for several more years(or waiting for it to be a classic), just do next oil change with Valvoline high mileage, or another seal conditioner additive.

Depends on how bad your leak is. Mine was seeping with occasional drips. The Valvoline high mileage is all that was needed and fixed it within several weeks. 2nd oil change completely stopped it.so, you're saying that I could just use/switch over to Valvoline High Mileage and it may fix the issue on it's own? or saying to do that PLUS the rear main sealer?
Don't forget to degrease the engine.OK... so I've done a full oil change... using Valvoline High Mileage, PLUS put in the Bar's Leak Rear Main Sealant, PLUS some stuff for ORings... now to drive around and see if it improves... fingers crossed.
Give it time. It'll work.at 50 miles now and still leaking and smoking
