Changed all rubber pipes today. Elbow from turbo to bottom intercooler pipe was really soft and on onside had bubbled up. Cleaned intercooler and did full servive (again). Also today i cleaned inlet manifold and fitted back on with new gasket and exhaust studs. Seems fine now revs up fine with no smoke. Next job is to blank off egr. Anyone know if this is worth doing. Also exhaust is blowing quite bad on flexi. Will this make performance poor because it still seems a bit sluggish. Cheers.
