How reliable is turbo
Hi I'm told there is some play in the turbo on my 1.8. How likely is it to give way? Is it better to replace now or wait until it deteriorates further and what would be the effect of that. Would welcome advice.

Play in the turbo's shaft will eventually allow enough oil into the exhaust flow to create blue smoke. Any hint of blue haze from the exhaust when driving indicates the CHRA will need replacing. The turbo compressor runs around 250K rpm so the shaft floats on an oil film. There's clearly a small gap between shaft, bearings and seals, but when that gets palpable, it means there's some wear. However, I wouldn't rush to buy a new CHRA unless there's a faint blue emission. Lack of clean oil in the sump kills turbochargers.

Up and till yesterday my 1.8t was running ok, but the turbo unit never been replaced or worked on and we are currently on 206,100 miles.
Hoping the mechanical problem that has sidelined us is a simple fix.

I personally would wait for blue tinted exhaust or turbo whine before replacing - i would also replace the whole turbo as opposed just to the CHRA cartridge - seem to hear a lot of stories of CHRA failure in the context of turbo reapir..

Turbos! Quart into a pint pot. Unhealthy way of powering a vehicle!

Many thanks everyone. I think I'll let it soldier on for the time being.

I was! I spent years replacing turbos on engines that were fine before the manufacturers started "messing" with them. Some of the old Ford commercial engines ran for the life of the chassis but with the "new fangled" turbos, they were cooking engines left, right and centre. The drivers loved them because they were much faster on acceleration but the mechanics hated them.

I think now that the engines have caught up with the turbines and our Rover ones seem to work very well with our engines as long as the engine oil is in good condition.--- |
