Checked in with the mechanic who will be doing the CV boot in a couple of weeks..... He will also be replacing the unbranded cam belt with a cosworth item, replacing the water pump with a cast non cavitation wheel item and installing an uprated RCM oil pump.
Just too many unknowns for me - paranoia was too much, when I do hit the track ill be happier in myself 😀
Some used but working bits will be for sale in 3 weeks time 👍
