hi , I am a new member with a 2004 copen that has done 125000 km I have no service records other then the last 2 . and they show that the oil and filter was replaced at a 10000km interval . so the oil has been in the engine too long ..... I would like to get the turbo rebuild , is that possible ?
Hello and welcome! Of course its possible to get the turbo rebuilt, but is it really dead? A new one can easily go into the thousands....
i didnt take the car for a ride yet , I need to give it a service etc .I did test drive the car for 10 min or so I didnt hear any nasty things from the turbo .... but i thought before it goes up in smoke a rebuild might be a lot cheaper then a new one ....
Warm up the engine, add an oil flush, drain, change filter and refill then test drive. Use that as a base point to evaluate the turbo condition, but turbo performance is also affected by other factors. Turbo seal and bearing changes won't be an easy job and I expect not cheap. Not likely to be an easy DIY job even assuming you can find spares and your probably not going to have the tools in a basic DIY tool box. Not even sure how rebuildable a Copen turbo is. It will need a rebalance if you strip it else it will likely tear itself apart. In my limited Copen experience the standard Denso plastic blow off valve did not perform well at all and the car now performs much better with a cheap Chinese rebuldable clone of a The Forge splitter. Maybe the Denso is crappy mabe my Denso was just knackered. 3000 mile oil changes are recommended by most everyone.
hee thanks , I do most things myself , but turbos is for the specialist I will get some info at a local turbo specialist . and will keep you informed . if the turbo blows up , its time to fit a bigger engine
I agree with Bemused, change the oil for a nice 0W40 or 5W40 + filter; oil flush is optional. If it does not make trouble after that I would drive it without touching anything
