What should I do now?
 

I've got my engine out (Carrera3.0 1977) ready to be worked on. I was going to attempt a tensioner upgrade and new clutch. However, I've had look at the mechanical tensioners and clutch and they all look pretty good. Looking through all the paperwork I found that the engine has had a rebuild about 25K miles ago. Here is a list of items the PO replaced..
Clutch
Timing Chains and Tensioners (mechanical) and sprockets
Piston Rings
Main Bearing shells
Drain tubes
And I found some photos of all the pistons and valves on a bench looking all shiney.
The car was running fine but used to get a little hot in traffic. Think I've solved this one when I found a poly bag welded to the top of the oil cooler! It leaks abit but then again it's old and I don't mind topping it up now and again.
My questions are...
Should I bother replacing these parts?
How long to mechanical tensioners last?
Or should I just clean it all up and get it running again. Been off the road for 2 years now and summers coming!
Your opinions are always appreciated.
Cheers M

I would:
Leave the clutch alone.
Still do the tensioner upgrade.
Update/Install a Carrera cooler.

If the engine was rebuilt 25K ago, then it's not old. Don't be mistaken by the rumor that it's ok if they leak a little.
