174 Turbo

Just to update, I came across the part from the Turbo which was blamed for the failure

While it shows signs of blowby and wear, its hard to believe that such a small part condemed my turbo and cost me a packet.............

I had the same problem with my 130ps t28 turbo,

Ha! No hallucinations bud, but my giant pink kitten has complained that he is having problems getting to sleep..

Had a disc removed in February but it seems like I have buggered up another disc and it is giving me crippling pains down my left leg, they have given me the tramodol to dull the nerves. The side affects aren't too bad but I do have to focus on one thing at a time otherwise I lose the thread of what I'm doing.. I'm off for an MRI tomorrow which I hope will throw some more light on the issue

Still not sorted mine yet, been on 6 Tramadol a day for my back so I've not been much in the mood for leaning over engines just of late.. I did remove the upper heat shield from the manifold a while ago and have noticed that there is black smudging developing round the welds on the manifold, suggesting that the welds have cracked so when I have the time and inclination I shall remove the entire manifold and get it all welded and reinforced but in the mean time I'll just live with it...

Turns out a gasket which was renewed when the turbo was replaced has shat itself after the grand total of 30 miles

Update:

Hmmm... Not at all sure that I would allow that mechanic fix my bicycle.

I would say that most turbos are wrecked by either not allowing them to cool down sufficiently before shutting off the engine, shutting off the engine and therefore the oil supply to the bearings before the turbo has slowed down or possibly the wrong oil... I am still amazed at the ignorance of some mechanics be they professional or DIYers to the importance of the correct spec of oil. I have heard plenty of guys with PD engines say that they use cheaper oils...

Another suggestion from the guy who rebuilt my pals RangeRover turbocharger was that older engines should never be flushed as this loosens crud which will find its way and will ultimately clog the oil ways to the turbo.

Just picked mine up and parted with another £230 - ouch

I give mine a good blast pretty much every time I drive it, it's unusual for the needle not to be past 120 at some point on a long motorway journey... :)
