[Healeys] Clutch bearing

[pieter scheenhouwer]

About to replace the clutch in my daily driver BJ7. The clutch has lasted nearly 20 years but I am on my third throw out bearing/bush. In the past I have heated the bush and soaked in oil for 24hrs before installing. 
 Do you guys think this makes any difference to bush life or have any other suggestions. I do a fair bit of driving in stop start traffic so the bush gets a lot of work.
Cheers
Piet
