My hawkeye started smoking lightly under boost so I thought instantly it would be the turbo in its early stages. I replaced this and it's only getting worse anyone had the same issue, hoping its not the rings

 

What colour smoke? Blue I take it?

 

Is it using oil? And a 2.5 uk? Have read plenty of posts on here regarding engine failure and ringland issues on the pistons, not saying it is but google 2.5 engine probs and a list will appear, best of luck with it fella, really hope it aint tremendous bad news for you

 

Doesnt sound good if the turbo has been changed.

best get a compression test, that will confirm either way. Good luck!

 

Yes it is blue smoke

 

Compression test to start with.

 

Yeah is using oil and iv read some posts about it was kinda hoping it could have been something else but looking like it ain't. Cheers buddy thanks for the replys guys

 

The most common issue is ring land breakage to the pistons.
I took this picture yesterday from a Hatch engine, (Same pistons) and you can clearly see the result! This owner sensibly hasn't carried on running it once the problem became obvious, so he's avoided real bore damage.



We are well used to dealing with this one!

 

What's the best aftermarket pistons to put back in?? Weisco any good ? Cheers

 

We would usually choose Mahle these days. They are a top quality piston and we don't get issues with incorrectly packed rings, which was becoming an annoyance with Wiseco. It was as though they were just chucking any old thing in the box. Only a perfect fit is acceptable of course.
When I say "usually" it's in response to the way all piston manufacturers batch produce pistons, and the fact that they aren't always available when you need them from suppliers.
Call me if we can help with any aspects of machining or building.

 

Hi Hibbs

If budget can cope go with Omega pistons, however plenty of quality alternatives as already stated.

All the best with it.
