Have you had a read of my post ? A few down from this one ?
I think it was called " turbo oil pipe link " Is this the same leak / area as yours. Perhaps ? |

The oil in the IC and the pipes could be from the PCV running from the rocker cover to the turbo. The crank pressure has to be let out, hence the port. This however causes the issue of oil also being forced through this, which is the reason it's fed back to pre-turbo (this is also partly due to the turbo creating an amount of vacuum to help pull this pressure & oil mixture through, though IMO, TD5's breath heavy enough to do it themselves).
This then mixes in with the incoming air and supposed to burn off, however, TD5's will start breathing heavier the older they get and if you start tweaking them (mine breathes like a trooper), so more oil will pull through and hoses will get covered and your IC will slowely fill up with oil and clog up. This however doesn't explain the patch on the floor as it shouldn't have anywhere to leak unless it's escaping through the joints of the hoses or your IC is full up and letting it out when not under normal running pressure. The other way of getting oil in your pipes is if the turbo is on its way out and letting oil through the seals around the compressor wheel (this could cause a runaway engine). Have a wiggle of the compressor wheel. Should be minimal movement at all. In terms of the patch, have you checked all the normal checks? Rocker gasket half moon? The front circle cam seal? The rear circle cam seal? Sump gasket? Turbo oil drain seals at both top and bottom? Oil filter housing gasket? Rotor filter housing gasket? |

taazzukcb thank you for your time in explaining this is much appreciated, ive now stripped everything open to have a look and firstly the turbo rota is good, and there is no oil coming through there, the U shaped turbo hose has minimal oil in side but this could have been blown out passed the hose clamps as ive noticed the steel hose is badly blistered, a couple hose clamps are threaded to, so im going to start looking for some upgraded replacements and see if that rectifies the leak..

Have you considered fitting an oil catch can? Something along the lines of a Provent 200. IMHO it is a modification worth doing as it prevents any oil mist entering the turbo and the subsequent carbon build up. If you go through life with your head in the sand....all people will see is an ar5e!!

My turbo pipe is wet with oil as well, I aslo have it on the end of the interncooler (turbo side) and on the upgright where the intercooler is mounted to. This drips down and wets the front chassis rail.
Now I have a spare intercooler I am going to strip out the old one, replace with the spare and degunk/clean/check the old intercooler for leaks/pinholes etc. Part of me does wonder if its blocked/restricted and causing extra pressure and now the oil hasfound the path of least resistance and is escaping? 1999 Defender TD5 110 Regards John M0VAZ Econet Station 48 no clock |
