benroden1983 Posted March 15, 2012 Report Share Posted March 15, 2012 Hi hope some one can help me!! I bought a 1999 1.4 lupo that has the ahw engine with 10700 miles as a project, when I bought it had a oil leak from the crank seal that I had changed !! So Ive taken it for a mot and it failed on a ball joint/wheel bearing& dreaded emissions on all three tests !! Ive changed the valve stem seal / lambda sensor / air filter / and run some redex through @ about 2500 rpm, and cleaned all the parts when doin the seals as the throttle body was full of black oily gunk!! When it's gone back to mot and it fails again, so I bring it home and do a compression test that was reading around 12 bar on 3 cylinders and 11 bar on the 4th cylinder !! Dose anyone have any ideas what this could be ?? Quote Link to comment Share on other sites More sharing options...
