nasty misfire

andy · 31-08-09, 08:24 PM

Got a problem with the UR, it has developed a nasty mis-fire, not constant but happens 90% of the time, cant get it out of first. Also when i rev it and then walk round the back of the car its spraying alot out of the exhaust, water i think.
have checked that all plugs are sparking and thats ok, thought maybe head gasket but have checked the oil and its the right color and no coolant is missing.
few weeks ago there was a problem with a wire behind the glovebox and if it was knocked then the car wouldnt start (glovebox was off) so just taped the wires and she fired up, could this e related??
many thanks,
Andy

andy · 31-08-09, 09:25 PM

any ideas? have been told when i bought it that it has an mb head, 2226cc block and hydraulic tappets if that helps anything

WR block cannot have an MB head as they are different, but lots of the parts on Johnathans old car were from an MB as it was a very late model WR. Nicely modded too if I remember a chase me and him had near Clocaenog in North Wales once. I had trouble loosing him in my S6

A wr can have an mb head

Oh no it can't, all the cooling apertures are different and WR head has shimms whereby a MB head has hydraulic tappets.
