dash vent tubes
Discussion
My dash vents and the tubes they slide into have become loose and rattle. I was going to drop the dash out enough to get a sealant gun in behind to silicone the aluminum tube at the back.
I see on the RV8 pages its suggested I remove the dash steering cowling. As I only want to drop it forward enough to get behind has anyone done this before? Would appreciate any advice.
I always used to remove the steering cowling to get behind the dash BUT.... having just watched a mechanic who is used to working on these cars he dropped the steering column, so much quicker and easier, and so much easier to pull the dash straight out, rather the sliding it out side ways (less chance of damage to both leather and potential cracking the dash)
Hi Mcosh, if you are talking about the aluminium 'housings' that the vents push into I recommend the following: When my car was stripped out for its retrim earlier I took the opportunity of completely redesigning the venting system, I will publish on this later, anyway with the housings just put some thin sticky backed foam (I used 1mm) around the inside edges, the vents then push firmly into the housings then. If you mean the 'Marley' waste pipe fittings that are glued into the TVR made housings, yes just either a silicon sealant or acrylic will suffice. I got rid of all the old pipes and aluminium housings, making new ones and using nice proper pipe fittings etc. Best regards, Pete
I re-made all the aluminium tubes and sockets. Has cured the rattles and the expandiding tube makes re-fitting much easier.

Yep was pretty unimpressed when I took a look behind the dash...
Will try and post some pictures of my solution. Basically I made some new aluminium sleeves, Tig welded the joints (rather than the TVR black sticky tape), punched 40mm holes in the back, fitted soem nice 40mm conduit fittings (which are fixed with flange nuts), used some 40mm 'pond' water system flexible pipe plus the appropriate 'Y' pieces and angles, put some 2mm neoprene around the inside of the sleeves so as the vents just 'snick in' nice and firm and seal, used the same foam around periphery of pipe the pushed it into the conduit fitting nice and tight. Voila, it looks neat, professional and works! By the way, my Griff had 40mm (1.25") pipe from the blower, pushed inside a piece of 48mm, which then fitted into the grey Marley waste fittings all glued and taped in!! Total cost about £20.Regards, Pete

Pete, you better add this to the list of things to manufacture for your fellow Griff mates, I'll have two sets please.......! I'm surprised you've got time for a real job. PeteRegards, Pete

I haven't that's the problem. When I go part time or take early retirement will have more time for all my projects! Just out of interest, if you had a Tuscan I developed a gas strut and hinge lifting mechanism for the bonnet for a local TVRCC member!
