Hello new to the forum and to the mini world, ive just bought a 2003 mini cooper s Lohan tuned. I bought it with a suspected head gasket failure but on removing the head tonight one of the pistons is knackered and scored the bore in the process.

whats my options on oversize pistons? cheapest place to shop?

Hi ya

Was the piston damage caused but destination or running lean can you post a pic

Pull the engine get it rebored and oversize pistons, there's lots of options for pistons depends on budget buy the best you can if your going to drive it hard.
Get a full gasket set victor reniz these are what mini use but 10x mark up, call express car parts one of the only places I have found that sell them.

http://www.expresscarparts.co.uk/productresults.php

Soon as it's back together and run in you need to get it on the dyno get the air fuel ratio checked.
Also while you gave it in bits check you vacuum pipe from you fuel press regulator to your Intake manifold this will cause what you have described

Or the quick option engine swap as mab says make shore you get a W11 not a W10 engine

Hope this helps

Thanks for your responses, I've had a ring about and seems number 3 piston in prone to failure, the bore is scored but if the option of oversize pistons are about then this is going to be the way forward.
I looked into secondhand engines but these are high mileage an probs no better off.

Best I've found at the moment are wiseco forged pistons .50 oversize for around 300 in America so I guess with duty ect looking at 400

This wAs only meant to be my run about now turning into a big project

Hi ya

Piston wise you have a few choices JE, CP, Mahle, wossner. Mahle are the standard ones if your not going to go made with power they will be ok to use.
Just make shore you get cooper s ones as the coopers are different co p ratio.

Hope this helps

Hi ya

It depends on your budget, there are lots of things you can do :-)
Me personally if the milage is high I would do the timing chain guides and tensioner.
May be swap out the oil pump always a good idea, melling make the pumps for bmw mini last pump I bought I got the complete pump and cover assy for about 40.

http://www.ebay.co.uk/itm/Brand-New-...item1c3d06cdf7

Victor reinz make the gaskets for bmw mini
Fit a set of ARP head bolts and rod bolts and cam bolt.
Check your supercharger belt tensioner the damper fails Express car parts sell the complete assy check you idler pulleys to.

May be replace the clutch plate oem or kavs, guide tube and thrust bearing.

Change the gear box oil.
fit magnetic oil drain to the engine sump (dimple)
Check and change the super charger oil both ends

Make shore you use the correct antifreeze halfords sell it in concentrate of mixed

Halfords | Comma G48 Antifreeze and Coolant RM 5L

Plenty of clean products gallons of the stuff red scotch bright

Blimey I could go on :-)

Hope this has helped and not put you off :-)
