  • Turbo Oil Leak

    Hi,

    I've noticed an oil leak from my turbo. There's oil dripping from the turbo (appears to be the intake side) onto my garage floor. My car has 100 000km on it with 5000km oil and filter changes.

    Is this normal for D4d's?

    Additionally, I have a squealing noise which I was told was and exhaust gas leak.

    What would cause these problems?

    Thanks,

    Answer: click the link below and read from paragraph #8 and this should give you an understanding what could be the oil leak as 100K seems to be low Ks for the turbo seals to be worn on the 1KD-D4D.

    Answer: This could possibly be a loose hose clamp on the turbo-intake hose and that it is possibly leaking turbo boost and causing a squeal noise and also possibly encouraging the oil leak at the turbo intake.

    Cheers

      Mine too gxl_d4d, same year too - 11/07

      No noises though

      Less than 100k km on the clock too - don't make 'em like they used to hey!

      Probably what messed up my EGR?

        Turbo Overhaul $$??

        Does anyone have a cost to have the turbo seals replaced?

          Not sure. Mine is being replaced under extended warrantee. I stumbled across genuine turbos on a US site a few weeks ago for around the $900. The picture showed the servo motor included.

              Just need the seals replace, hopefully not the entire turbo!

                Had turbo replaced about 2 -3 weeks ago under extended warranty. The dealer said the same thing, leaking oil and I had also noticed a hi pitched noise (fant though) which is now gone... Mine has only done 84,000 kms!

                Cheers

                  Seccond the turbo replacement, mine was starting to weep oil, that was done at about 74,000 under warranty, they wanted to do just the seals but ended up doing the whole turbo under warranty.

                    I have had my turbo replaced under waranty also, sounded like i had a very small chip or damage on the compressor wheel. I have heard that they cant replace parts on the turbo assembly, has to be done as a complete unit..........

                      Just FYI one of my customers has a 2008 120 D4D which has done 100,000k or so and has recently moved to QLD from NSW. When he went to a Toyo dealership here for a pre-rego inspection they pointed out an oil leak from the turbo and quoted him some astronomical sum to replace it, as well as failing him on the inspection apparently.

                      He then contacted someone experienced in turbos he knew and trusted from his old stamping ground in Coffs Harbour who assured him that the design of the turbo meant that over time during normal operation oil will pool on some small lip internally and when it reaches a certain level starts to weep out and so, there's a "leak". He actually went back down to the guy who I believe removed the turbo, gave it a clean or whatever and recommended a catch can.

                      Anyway the end result is he's happy he doesn't actually have a leak and that what he saw wasn't a real problem.

                      Just my 2 cents.

                      Cheers,

                      Dave

                        The inlet housing can be resealed with silicone sealant. It will stop the external leak however if the internal seal is stuffed, you'll end up with a lot of oil in the intercooler and intake manifold which will gunk up over time with EGR gas.
