Hey Eric! Big thanks on your tutorial on how to perform a parasitic draw test. HELPED ME TONS!
I have a 1998 mercury villager (Quest) Nissan 3.0 motor. It had Major sludge I tried to clean out as much as I could under the valve covers. replaced all the valve stem seals using the Ole rope in piston cylinder method and a harbor freight spring compressor. I put it all back together and now it wont start. I have electric/compression/fuel. Ive checked all hoses and sensors and other basic things. I did however remove half the oil from engine and filled the other half back with diesel fuel and ran it for 10 mins. I did this 3 times before I started the valve stem seal job. THANKS HAPPY THANKS GIVING!
