+1 on Everything , But I wondering Why No one mentioned the Thermostat Housing being the Issue - with the New Hose Kit .. ( Unless that's Part of IPD Hose Kit )
Other Item seemed to Slide right By , TCV Acting Up will usually Degrade to Very Low Boost very Quickly which leaves U in Limp Mode - really - Fast with Possibly a few Days of Squirrel Behavior 1-2 Drives Before Hand ..
Shifting these Fine Mesh Gears on the M66 - is very much like Shifting Motorcycle ( Quick Clutch with Light Feathering with Quick Shift - Not - Fast ) The Gears will just Click Off like running Up through Gears on Motorcycle ..
Many Owners Find themselves doing 3/4 to Full Clutch - to - Shift and that's where it gets Slow and to Hard to be Smooth .. ( Transmission has Slave Cly. which Acts as Limiter ) If the Clutch is Let Out to Fast -
Slave Cly. Fitting WILL Limit Fluid Flow and Clutch will Slip & Heat & Then Burn some If - RPM's are Not Instantly Reduced OR Disengaged !
Like on Very Steep Hill - this may Happen Very Fast ( If You Engage Clutch to Fast to Catch Vehicle - from Rolling Backwards ..) ( Yet U don't want to Roll Backwards ) say someone is Right Behind You ..
Practice Very Steep Hills - Starts , just so U don't have an Issue when Situation Accrues . .
