Customer Question

Hi My name is ***** *****. My Toyota Diesel 3.0 D4D turbo has started to leak oil from the bottom of the unit. Can you suggest what is the problem please?
JA: Thanks. Can you give me any more details about your issue?
Customer: Thank for your reply Matt. I noticed oil on the floor overnight where I usually park the car. Checking for the source of the oil leak I put my fingers on the bottom of Turbo there was bit of oil on my fingers. Check all the pipes leading in & out of the unit all were secure and there was no oil leaks on any of the rubber pipes.
JA: OK got it. Last thing — Toyota Mechanics generally expect a deposit of about $20 to help with your type of question (you only pay if satisfied).

I'd 1st then remove the high pressure intake hose after the turbo and have a feel of the turbine wheel - there should be no play radially at all - but a little bit of axial / end to end float is normal

also check inside the pipework for oil deposits as a worn turbo can lose oil through its shaft seal

which then gets drawn into the engine

and also check the oil feed pipe to the turbo ( on the top ) and the drain pipe back to the sump on the bottom
