luk Posted May 9, 2009 Share Posted May 9, 2009 Hi everyone, my turbo blew on the motorway and as i pulled up the engine reved at full till i stalled it to stop it. Iv had a new turbo fitted but there is still a major problem The garage says it could be a bent valve or con rod due to the oil been forced in engine, but they need to investigate. The car drives but wen pressing accellerator the engine vibrates and is slowish to pik up, but when u just hold pedal steady doing 2000 to 3000 revs the car feels fine and cruises along, its just when you press the pedal. It surges and struggles The garage cleaned the intercooler, inlet manifold twice. The car starts fine and idle`s ok ish, maybe a little iratic, and revs ok with no noises from engine.There are also no warning lights/codes When the car get warm u get a few drops of oil coming out of exhaust and a bit of smoke off this, so there is still oil in sytem. My next plan is to remove intercooler and try and drain oil a bit more if theres any in.Iv also added some fuel system treetment. ALSO iv removed the EGR valve , iv been told i need to clean this ? how do i do this ? is it the halam key socket on the valve ? ANY IDEAS on what it could be, and does anybody think it could be the valve / conrod ? when it is fine when idleing What would be the best way to clean the intercooler ? Thanks in advance for reading Quote Link to comment Share on other sites More sharing options...

Thanks in advance for reading sounds like your system still have a fair amount of oil in it. You will need to clean all the pipework connecting the intercooler etc. Also give the egr valve a clean as its probably contaminated aswell. not sure on what you could use to clean the parts, carb cleaner is good for egr valves though.

sr-performance Posted May 10, 2009 Share Posted May 10, 2009 Hi mate, should think when your turbo blew it will have lost oil into the exhaust which may have contaminated your cat which explains why your getting oil droplets from tailpipe.. steve Quote Link to comment Share on other sites More sharing options...

jasmeet Posted May 29, 2009 Share Posted May 29, 2009 just be gentle, and the oil should burn off in due course. after some time it might be a good idea to clean the pipework Quote Link to comment Share on other sites More sharing options...
luk Posted May 29, 2009 Author Share Posted May 29, 2009 thanks jasmeet, yes iv cleaned inlet and outlet pipe and intercooler has been washed out (they were dripping in oil) iv done about 60 miles since, not sure if geting better or not it seems to struggle at 2000rpm , very juddery , sometimes shaking the car nobody seems to know the symptoms of a bent conrod or bent valve (thats what garage said it could be) it idles over ok and is notbad upto 2000 rpm and over 2400 rpm one day it stalled, then when i started it , i got tons of smoke out of exh so i parked up for the night and iv not had any smoke like that since Quote Link to comment Share on other sites More sharing options...
