A New Turbo?

Recommended Posts

Hi,

Amongst the many things on my to do list I came acorss an issue with my turbo and was wondering whether this problem is going to be repairable or whether I'm going to have to fork out for a new turbo.

There appears to be a small crack on the outside of the turbo near the wastgate. Upon further investigation this crack has gone right through into the internal part of the turbo. Would it be possible to repair the crack by welding it up? Or am I going to have to shell out for a new turbo? I'm pretty sure there was no 'gas' leaking as there is no build up of carbon around the 'outside' crack.

Thats not ideal is it! :scared:

I'd not think welding was much of an option on a part that heat cycles so much and with such severity, then theres remachining the seat for the valve...

It doesn't look to positive for a rescue!

Braze might work, but it'll need a professional to do it, it'll need careful heating in an oven, brazing quick and cooling very slowly.

Bugger!!!

Bibs thanks for the offer about helping me to source a new one, I'll probably contact you when I get round to putting the engine back in. Might be a while though, I've still got to:

1) get the right fuel tank out and recondition both of them (thankfully they're not too bad)

2) reassemble the front suspension

3) Fix the heat damage on the chassis

4) Generally tidy up the engine.

Actually whilst I'm here is there anything wrong with powder coating the fuel tanks? I'm just thinking about protecting them for the future.

Someone's going to be a busy boy this winter!

While the tanks are out you'll do well to use something like this to prevent future problems.

Remember to replace the foam with some closed cell stuff :)

Is the turbine housing unique to Lotus?

Normally they are made from a small number of housings, bearings and so on

Maybe a call to Turbo-technics or another turbo specialist might find you a replacement housing.
