My car smokes and now I know why....

After a hard run when I park the car and raise the bonnet to let everything cool down, I notice a lot of smoke coming from the back of the engine. I thought I had blown the rear seal on the back of the crank but found that not to be the case when I changed my flywheel. What I have has got to be unique to my car. When I installed my Falcon headers and the Falcon dual sport exhaust, I found that there is virtually no way to "hang" the exhaust system because of the size of the pipes and the huge size of the Falcon mufflers. Soooo, I decided to rigid-mount the entire system aft of the tunnel by making two cross braces on the frame and bolting the rear of the exhaust up tight and high. The middle part rides on a wide U-shaped cross brace right behind the tranny mounts and in front of the tunnel. Yes, I know, you can't do that, the system has to move or you will crack the header. I solved that by having made up 2 custom-built triple-walled stainless flex pipes and install these between the header and the rest of the exhaust. These two 10" flex pipes allow the sytem to vibrate and expand or contract without any problem. The only problem is they are mounted right below the transmission, and when I press the car hard, it weeps a bit of oil, just enought to get on the flex pipes. Now, I insulated the flex pipes with some fire-proof (I tried burning it with a torch, no go) fabric that wraps the flex pipes to insulate them from the overdrive. So in reality, it is my overdrive that weeps oil, not my tranny. John has tried everything to stop this but to no avail. Just a little, expecially when stressed, and enough to get on the cloth and create a fair amount of smoke. I was thinking of going over the top with a piece of thin-gauge aluminum to see if this would help. Like I say, no one else would have this problem. The exhaust system works for me, just the oddball flex pipes get very hot and don't like oil in their blankets. Any comments or suggestions.
 
Put a diaper on your tranny! /bcforum/images/%%GRAEMLIN_URL%%/jester.gif

Seriously, you might be able to use a heavy foil or thin aluminum sheet around the tranny to direct the offending drip away from the pipes. Just make sure it does not collect the fluid and cause a greater risk.
 
I like the idea of the SS sheet metal covering.
In the industrial pipe insulation world that is used as a jacket for mechanical and weather protection over the insulation and is secured with SS banding.
At least the metal would avoid the fire hazard from a more porous covering collecting oil and eventually lighting off!

Of course you could just lighten up the right foot but where's the fun in that?

4WD and off road vehicle use metal shielding that surrounds the exhaust pipe leaving a gap for air to move through. You would only need it on the top and sides.

Wash your mouth out, son.


Actually, today it happened when I drove past Stirling Sugars sugar cane processing mill. There is a housing unit where the Puerto Rican sugar makers live in (this is a highly trained specialty that it seems only the Puerto Ricans are good at), and it is in a wicked S-curve. I gotta go by in second gear at about 4K rpm and give them a rise. They always cheer me on. I speak enough Spanish to know they are impressed. I got carried away today.

I wonder if Pedro was there with them barbecuing???
 
Pedro was busy getting another fine restoration ready for delivery to an unsuspecting new customer.
 
It's the wiring harness!!!!!!!!!!!
The oil smoke is just a 'smoke screen'.......

I know a little about magnets, ceramic, ALNICO's, U shaped, shorting out a magnet, etc. etc. and even the attraction of static charges;

BUT, I have never read anything about the magnetic properties of any and all exhaust systems fitted up to a TR6 that make them a very strong magnet to oils. It just defies physics. What does ferrous got to do with magnetism? Zink in the oil, but it is not ferrous and where is the magnet?

Nothing to do with magnetism. It's all about gravity. The oil drips down onto my very hot exhaust flex pipes and smokes.
 
Think he was poking some fun there Bill?
