Hi,
I just got the mini back from the radiator shop(reputal company). Ended up buying new radiator had system pressure tested. On the invoice it had,
COMBUSTION LEAK TEST(Positive)
QUOTE- When a positive test is indicated, exhaust gas is present in the cooling system. The test device used is a proven west german brand sensitive to detect small amounts of exhaust gas. Unlike more readily available 'suction' test kits, theis device is pressure fed by the engines own gasses, and indicates a result up to three minutes after the engine is switched off. Some engines with exhaust gasses present may continue to operate with no apparent side effects, but with a positive result we recommend you contact your mechanic/technician for further advice. End quote
The oil on the dipstick is not a milky cover.
Is this a head gasket?
Would this explain lack of power?
Thanks
It's probably a head gasket. Yes, it could affect power a bit. I'd do a compression test first, or just pull the head and fit a new Payen BK450 gasket. They are good, and pretty cheap.
Make sure you get both head and block faces spotlessly clean.
