Hi All,
Changed the head on my Gen 3, over weekend. Fired up more or less first turn of the key but sounded a bit rough.
Things changed
Head & gasket, also gaskets for every bit removed
Oil & filter
Coolant, thermostat & rad cap
Timing belt, tensioner & idler
Fan belts
I have the following issues
Noisy top end on start up for first few seconds which disappears
Misfire between 1750 & 2000 RPM that seems to disappear when warmed up
Black smoke on start up (really quite bad) that goes once warmed up
Doesn't switch of instantly and shudders to a stop regardless of temp.
Drives & pulls OK however, and once warm sounds better than it ever did at idle. Today it would not start without the aid of some easy start.
Things I have checked.
Timing belt - marks are all bang on
Vacuum hoses checked for correct placement and for splits,
Correct fit of injector pipes
Injector pipes cracked - fuel to each
All plugs / electrical connections are secured and correctly fitted
Only non-planned thing during head swap was accidental loosening of an injector, rather than undoing the whole thing, I split one of them which was quickly torqued back up to spec.
Anyone got any ideas or had a similar issue?
Many thanks
Ben
