Auto Mechanic Needed for Engine Repair

I need an expert witness inspection order by the court. I took my Renault traffic in to a garage for a new starter motor and on collection coming out of their garage there was a massive oil leak. On taking it to another garage it was found that they had removed the metal oil feed pipe from the turbo and did not put back the oil seal when refitting it. They have denied liability and the judge has order a inspect/report from an expert witness Ideal skills and experience: - Proficiency in engine repair - Experience with oil leakage problems Please provide a detailed plan and cost estimate. The vehicle is located in SA16 0HZ area. My number is 0780 5040501
