The GT6 has had a bit of a blowing exhaust under acceleration recently, so I checked out the exhaust system today. I did find a slightly loose clamp where the downpipe meets the mid section but having just taken it out for a test drive that wasn't it. I've also had a few issues with pinking under acceleration lately especially when the car gets hot.
Having revved the car up on the driveway after the return from the test drive I can now hear that the blowing is coming from the manifold gasket. That's probably why the car is pinking as well as the gasket is a combined inlet and exhaust manifold gasket so it may well be leaking on the inlet leading to a weakening of the mixture at high vacuum.
The car is hot now so I can't really fix it yet as I haven't got asbestos fingers!, but at least I know what I need to do to sort it out later...
My Trials and Tribulations with My GT6, on my Suzuki T500 and previous antics in my Dolomite (now sold)
About Me
- Andy Cook
- Fleet, Hampshire, United Kingdom
- I've owned the same Triumph GT6 since 1988. A 71 Rotoflex model, over the years I've replaced nearly every mechanical component and I've had some major body work done. I'm a firm believer in using my car,I've driven it to Europe sveral times visiting Holland, France, Belgium, Germany, Luxembourg and Switzerland. I've also completed the Club Triumph Round Britain Run in it twice and got as far as John O'Groats a 3rd time. Prior to owning the GT6 I owned a '76 1500 Spitfire and a '76 Dolomite 1850. In 2013 I expanded my collection of Triumphs by adding a Dolomite 1500hl with overdrive, which I subsequently sold back to one of it's previous owners, my mate Darren in 2021. I'm an active member and club official of both the TSSC and Club Triumph holding the post of TSSC GT6 Register Secretary and Club Triumph Area Group rep for North Hampshire. I've now re-entered the field of biking having purchased a 1975 Suzuki T500 2 stroke twin after a break of 35 years from two wheels
