Hey folks new to this forum and need some advice on next steps. Back in Jan , I bought a 05 mineral grey GT and drove it from Pittsburgh to Philly where I live. Car had a few owners but only 53 k miles. The seller seemed like a trustworthy guy, but since then I'm convinced this private pilot was a lying s.o.s. knew there was an issue and lied about health of the motor. Incidentally the car ran pretty good for stock. Regardless karma usually catches up with people like that. Once home the next day I checked the oil and it was down almost 1/2 quart , so I figured I misread the level the day before since it's only about 320 miles. So I changed the oil and within a week or or so lost a quart, no leaks no bad smoke out the exhaust that I could see. Another week and I picked up a misfire on #6, started poking around and found a new coil pack on 6 and decided to pull the plug, which was badly coked up. Pulled the rest of the plugs and did a compression check. All are around 190-210 except 6 which was at 55-65 psi. Added teaspoon of oil no big change. Rotated the motor until all three valves were closed put some air pressure in the cylinder and really couldn't hear any leaks out the exhaust or through the intake. I'm thinking bad rings or maybe hopefully a head gasket? do theses motors have an oil passage to the cam followers between the cylinders? Btw have not seen any oil in the coolant...thoughts ? thnx for any ideas.
