Hawkeye STi 2.5 - Burning oil and oil in coolant
My car is obviously poorly. Been using more and more oil lately and I notice it has contaminated the coolant too. What might this be?
It still pulls hard. But I'm assuming I'll need some kind of rebuild. What do I need to have done to make a 2.5 reliable at around 350bhp?
Thanks

Sounds like the headgaskets have gone. A compression check should determine this.
It could also be ringland damage.
Both will require the engine coming out and if it is just the gaskets, then I would recommend doing the pistons at the same time in case they have gone or about to go.
Gaskets could be anywhere between £600 and £1000 to do.
Pistons will be that plus the cost of the pistons of around £400 to £500 plus additional labor and possibly a re-hone or if done high mileage, a re-bore but some don't recommend this on a 2.5.
