If that doesn't work then try a very small amount of easy start down the side of the intake manifold inlet, where that rubber joint is undo the jubilee clip and push a screw driver down the side to make a gap to squirt down.
Only use a very small amount the D5 really doesn't like easy start and will sound awful. But it might help to clear those valve seats. |

Mine did take a total of about 10 seconds cranking before starting, following reassembly. This was one long crank (~8 seconds) with a 20 second pause, and it then started 2nd time (slightly lumpy for a couple of seconds and then perfect).

Hi and grazias for replys...
It started after couple attempts, no leaking at fuel lines, but it blew valve cover gasket in front right corner and also injectors 3,4 and 5 are leaking.... Hmm, I'm gonna repeat the process w/t a new gasket and small sealant spots and new injector clamps, bolts and of course new cooper washers. Hopefully it's gonna be ok, I 'm using torque spanner for 10Nm rocker cover and 13Nm injector clamps. |

When you say front right corner, do you mean the corner where the swirl flap control arm sits? If so, there is a rubber grommet holding the swirl throttle axle in place that needs pushing down quite hard into the cylinder head. Either way, there shouldn't be much air pressure inside the top cover. If anything, there should be suction of air. Maybe one of the intake valves isn't seating (as per previous suggestion) and combustion pressure is filling the top cover ? It must have taken a lot of pressure to flex that top cover. Was the gasket well seated in the top cover grooves? It should sit in place nicely and not fall out when you're fitting the top cover (no sealant needed). I only replaced the copper injector washers when I did mine, but did thoroughly clean the injector seats in the cylinder head until they were shiny:

Hi Semnoz I am just in the middle of replacing my swirl flaps - looking at your other detail post on this but seems to be locked for reply for some reason - anyway just wondering how you cleaned your inlet ports? have the cover off and the ports are full off oily gunk, but presumably if you disturb too much it is going to fall into the cylinder or get stuck on the valve seat...is this a problem or I guess it just gets burnt off?? My flaps seemed to be stuck closed but didn't notice any problems with power or error codes. thanks for any advice.

Hi - I am replacing my swirl flaps now...so would you suggest I don't try and remove any gunk from the inlet ports? being a clean freak I can't resist making everything shiny now I have made the effort to remove everthing. thanks

Wouldnt a tow from a friend be the answer. (Unless you have an Automatic car) I have had to do this when changing a cylinder head after a broken Timing Belt destroyed the Cam Shaft and several Valves, and finding the battery had gone flat, it would save a lot of mucking about with booster batteries etc.

When I replaced my swirl flaps, I tape a small length of hose to the end of my Henry Hoover hose and used this to suck away the carbon while cleaning the inlet chambers. Again using the hoover to suck any carbon down the injectors sleeves. Taking your time, double checking everything is clean is well worth while. Turn the key to No2 for a couple of mins, and away she starts. Smiles all round.
By the way Henry Hoover is mine not the Mrs so no ass kicking there lol |
