Another V/P engine problem

[mldpt]

Due to poor starting over the last season and increased smoke, I have had the injectors on my 2003 serviced £180 hopeing that this would cure both problems, it did cure the smoke problems considerably, but not the starting, so I removed the head and had the valves and seats ground, the exhaust valves were all verybadly pitted, ( all on one side of the valve ) While I had the head off I also replaced the engine mounts, but altered nothing else, I replaced the head and great cmpression and she starts first time , but now there is loads of smoke, unburnt desiel smoke, any sugestions please, I have had the injectors checked again and they are spot on, and have checked and reset the tappets.

Is it using oil?

Is the injection timing correct?

Hi Steve.
No not realy but its definetly unburnt fuel I have had a second opinion on this and had the injectors checked again, I have checked the tappets again and set them a thou over as sugested by the enginer he sugested the timing but as nothing has changes since it was running before doing the head, the timing I believe is set for each cylinder by shimming the individual pumps. I think the smoke is less now I have increased the tappets to .014"

Have you checked the air filter?If it is blocked only part of the fuel will burn,and starting will also be difficult.

Is it getting enough air, either form as someone said the air filter or the engine bay itself. Try running with the hatch open.
Opening up the tappets making it better strikes me as being low compression, as by doing this you're increasing the compression slightly. Although as you say it starts first time then this seems unlikely.
