Well after coming very, very close to selling the SC to fund the purchase of a pre-impact bumper 911S restoration project, I've decided to keep the car and leave the early stuff alone as the rust is on another level to IB's although the prices being asked doesn't reflect that.
So having made that decision, I've completed a couple more 'preventative maintenanace' jobs over the last week. Installing the hydraulic chain tensioner kit (thanks Matt) was the first task.
The first stage was removing the rear valance, silencer and engine tin wear to gain access to the chain covers. The dizzy also needed to be removed to gain access to one of the oil lines.
Then removed the covers and fitted the new tensioners (after securing the chains in place)
Then installed the new covers/gaskets plus gasket sealant for good measure...
Followed by the new oil lines and modified tin wear...
The engine is now less noisy so the old tensioners must have been getting tired so glad this is completed. Next up was to remove the valve covers to check the head studs and cure some minor oil dampness. Hands were too oil covered to pick up the iphone and get more pictures at this stage but all head studs OK and new gaskets now installed.
Then removed the reflector to fit a new bumper seal using high temp adhesive rather than the self adhesive tape.
