So, I have a new cat, new sensors, air intake, lambda, MAP, crank, coolant and 2 brand new injectors from minispares (sorry Alexmozza).
I have lapped the valves in and smoke tested the inlet to check for air leaks, none visible.
I've done a leakdown test and it is leaking down the bores.
All I need to do now is take it back for a retest.
Watch this space.
