Hmmmm,m im losing coolant. My oil looks fine except for a bit of yellowish goop in the filler cap (it does NOT look like headgasket milkshake oil). On the dipstick it looks clean and normal. Oil level is consistent since camcover was tightened (WIN!) about 90% driving is short distance. no puddles etc underneath. the mechanic used lucas engine flush last service. Running 100% synthetic. Also flushed the coolant.
