After a year of intake valve problems we have managed to take out not only the under 2000cc 2wd class but also the outright 2wd state championship. The poor old 2 TG is being stressed fairly hard and has shown up as problems with intake valves. We only get 300km on a set of valves. I have tried stainless and titanium with no luck. I have tried soft valve springs and hard. does anyone have any suggesions. The cost in head gaskets alone is $1000. Go the 2t-g Andrew V
