Cockpit exhaust fumes

Share this page

Wooolffy brings up a good point about making sure the gap in the trunk seal is at the top side of the trunk (closer to the fuel filler than the latch). It sounds as if you have already run the routine of gasket replacement including the lens to base and base to body gaskets for the rear lights. Another trick that I did was to strip out the rear interior and vapor seal it with plastic and duct tape (just like the Dept of Homeland Security suggested /ubbthreads/images/graemlins/grin.gif).

I did that before I drove the car for an entire winter with the hardtop in place. Never encountered the "Triumph Smell" again with that set up. Items left in the trunk though would still smell of exhaust. Since my rebuild, the hardtop has hardly been on and the soft top has hardly been up. My windblocker set up keeps the cockpit exhaust free though.

with the seam at the top side of opening. I then greased gasket and adjusted lid to fit compressing all the way around lid.

wooolffy Will definitely try your suggestion.

can do that 'bro.

Ah... vettedog72...don't get smart. This ain't no Cobra.

I was thinking about Healey's, and AM's........... geesh, I must have lost my head for a few minutes /ubbthreads/images/graemlins/smile.gif
 
I guess you did. BTW it ain't no 60's/70's 427 StingRay either.

not really put the tail pipes on a 6x6 ond stand/jump and make sure your hanger is up as far as it can go with out hitting the frame
 
Alright, Thank you. soup111

Have the same problem with the TOP DOWN when you come to a stop. The trailing exhaust fumes just catch up to the stopped car and wash right over it. Grrr!
Maybe bend the pipes down a little or out to the sides ???
 
Same problem here. I've been chasing it since I've had the car, going on 12 years now. I have tried sealing off ahead of the fuel tank using tape and plastic, but admittedly I am not sure how well I got it sealed. I wonder if the winter sealing film for house windows would be any good? Sources of fumes can be oil cooking off the motor if you have any significant leaks, fuel fumes from leaking carb seals, gearbox leaking onto the exhaust(?), but I too have been convinced a lot of it is from the tailpipes. I have cheapo slash-cut chrome tips on the stock pipes, which don't look great but hopefully encourage the exhaust away from the back of the car (they bring the pipe out about an inch or two behind the bumper). I have never noticed soot trails going into the boot (we can say boot on here can't we...?). I will take a look at the seal. One thing that mystifies me somewhat is that, having a poor seal around the lower *rear* edges of the doors, I get a strong positive pressure draft when I'm going down the road. If anything I would have thought there would be suction there.

In any case, I will try some of the suggestions this spring and see if I can make any improvements...! Pete
 
Go to pep boys or some place and put a long extension on your exhaust pipe for a test to see if that is the problem. Maybe one that deverts exhaust down?
 
Heard that jlaird.
Am wundrin' now whether the presence of a luggage rack makes a difference in vortex activity or perhaps whether single or dual exhausts are more or less apt to draw fumes into the cockpit or would a rear spoiler exacerbate or eliminate this phenom.
Looks like I'll have to head to my local neighborhood wind tunnel and experiment with some modified TR6 rear profiles. Heh,Heh,Heh.

One of the quirks of the TR6 is the Kammback design that creates a more pronounced vortex or vacumn effect at the tail end. Every TR6 owner has to deal with washing that nice layer of exhaust film off the rear of the car and bumper. I always felt this is one of the reasons Triumph decided to paint this area semi-flat black. I call it "exhaust-gas black"! My duals have rather large scavenging tips on the tail end and extend about 3/4" past the bumper. I know when it is time to tune the car by reading the colour of my rear bumper. i.e., sooty bumper=carbs set too rich, and on. I really don't notice exhaust fumes in the car.

I had a look last night, and my trunk weatherstrip is installed with the gap to the rear of the car, and it's about a 2" gap. I'll plug it off and see if it makes any difference next time I drive it.
 
I wonder if flipping your sunvisors up would help to break up the back wash ?
Someone pinched my previous post by the way....
 
Right about that TR6Bill. My rear bulkhead gets enough crud that plants could take root there.
 
uuuuuhhhhhh ohhh looks like you guys are gonna have to try side pipes.....lol /ubbthreads/images/graemlins/wink.gif im curious though, has anyone seen a nicely done set of side pipes, say perhaps coming through the rockers like the modern mustangs? or has anyone ever experimented with using healey mufflers on a tr6? i was curious about this one since i love that healey sound and i think that these mufflers would be a little bit quieter than the monza ones....??
Randy
 
TR6BILL says he does not have the problem with fumes. Other than Bill, I have not read anything from anyone that does not have a problem with fumes.

Side pipes; OMG! Through the rockers.... you butcher. Like a Healey; now that needs censoring /ubbthreads/images/graemlins/smile.gif
