Ay up Stu,
I've just done alot of work on my engine. New throttle body, TPS sensor, thermostat, and injector seals, which meant I had to take off the inlet manifold, so i put on a new set of manifold seals.
I had replaced the seals about 7 years ago. The old ones I just took off are as soft and supple as the new ones, just a bit discoloured.
You are welcome to them if you want to PM me your address.
Cheers Kev.
