Over the last few weeks, I have had an "SES" light come on 3 or 4 times. When reading the code(s), I get P0303 Cyl 3 misfire and the BMW code P113C pre cat O2 sensor. Read by a generic Autel code reader. I have had the P113C code before, about 2 1/2 years ago.
I only use an OEM coil, NGK plugs and wires. All less than 3 months old. Nick at Detroit Tuned suggested doing a compression test to determine if an exhaust valve is bad or the rings. I will do this at the weekend. Already fitted a new NGK O2 sensor, and cleared codes.
Nick also suggested using Cooper S valves, less prone to burning out, and doing timing chain/guides at the same time. Car currently has about 128000 miles on it.
If I do this myself, the valves as supplied by DT would be about $330 and the timing chain/guides about $180. On top of this would be all of the gaskets, etc. This little project could end up costing $700+, if I turn the wrenches myself.
Although the Justa is in generally great condition, apart from stone chips on the bonnet, I don't know that I want to throw that kind of money into a 10 yr old car. Budget always has to be an issue, I'm the only wage earner in a household of 5 (including 2 teenage boys!!!!). I guess that I could sell the stuff that I have accumulated for the car (center arm rest, Redline armrest cover, new boot tray, etc.). Or I could just trade it, and let someone else have the potential headache.
Some local KC club members had been getting this code for a while too, and had thrown plugs, wires, coils etc at it without curing the problem, so they called me...... I loaned them my compression tester and sure enough - 50lbs on cyl 3.
They did the work themselves (other than the machine shop to do the valves- which was about $400 too!) and they wound up replacing the cam as well......the car now runs as well as it did when new and they are still in love with it - it's a 2005 Justa Cabriolet BTW with about 200K on it....original CVT too!
So, unless you're just ready for a new car, like Dave says it's a worthy investment.

Thanks for the input. Car payment is not really an issue, as we've been thinking of replacing my wife's Dodge anyway. Would trade the MINI against a new car for her, and I would take over the Dodge as my daily driver.
The [U]only[U] thing that makes me even think about fixing the Justa is how much I enjoy driving the damn thing. Get behind the wheel of a Gen 1 MINI, and all reasonable logic flies out of the window.
In all I have ordered almost $1500 in parts to refresh my 02 S. I can't think of a car I would want more with the exception of a 06 JCW or a Gen 1 GP. So to me it is worth fixing. I really wish I could send the motor to RMW and let them do their magic, maybe some time down the road.
The cheapest car is the one you already own. If you still love it fix it, it has many more miles left in it. If your MINI has a CVT (ticking time bomb) trade it in, because that one will kill you with its replacement co$t. Good luck.
