After condition inspection was complete and brake leak fixed, I put all back into place and cowls on and did engine start and 2000 rpm idle to get engine oil temps above 120 degrees and then ran up to about 4300 RPM. By the time I got to that point, the CHT was over 285 and flashing red so I shut down. Took off cowl and found fuel, oil and coolant leaks onto ground. Found the fuel leak in fuel pressure transducer but could not find source of oil leak nor coolant leak. I think oil may be coming from oil vent line but there sure is a lot being blown back onto fuselage, gear leg and tire. Could not find even a trace of a coolant leak. Not sure what is going on.
