Car was recovered today! Everything appears to be good! Thanks for looking!

My blue 81 280zx was stolen last night. Please keep a look out!

Yes coolant in the cylinder. I went ahead and ordered a head gasket set and will be pulling the head as soon as I get the chance.

Last night I put it back together to start it and revisit the symptoms. It didn't want to start and the cooling system pressurized just from cranking. Pulled a spark plug and cranked it and there was coolant mixed with the fuel...

Sorry I was out of town for a few days. I was loosing fluid so I don't think it was just the gauge but I have been wrong before. The thermostat, radiator, radiator cap, fan clutch, water pump, and radiator hoses are all less than 6 months old.

Temp gauge was pegged and coolant was gurgling. Cant remember ever seeing steam coming out. When the temp gauge went past normal and kept rising, I killed it pretty quick.

I left all the plugs in except the one being tested, disconnected the power from the injectors and the plugs then cranked at wot for 10s. Repeated for each cylinder

This is the quick rundown I have an 81 non turbo. It overheats bad pretty quick. The cooling system(radiator, fan, water pump, thermostat) has all been replaced recently and is in good working condition. My thoughts are broken headgasket. There is no mixing of oil and coolant so I would assume it is broken between cylinders. I compression tested it and these are the results: 1. 174 2. 156 3. 155 4. 160 5. 173 6. 179 I have not diagnosed many engines, is the psi difference great enough on cylinders 2 and 3 to warrant my belief that it is a headgasket? Any other thoughts/ideas? Side note: The test was done cold. The car has been sitting for a while and I have been tinkering. It was also done dry, no oil added. What do you think? Am I missing anything?

Thank you! Yes I love this car. And yes that is my fd as well. As far as plans go, it needs a rebuild. And I am trying to decide if I should just leave it as that. It was a great daily driver and I was happy with it as that. But I am always tempted to make it faster.

Hi everyone, Im new! I have had my na 81 280zx for just over 2 years now. I plan on hopefully rebuilding it this summer. As a new member I promise to try to search everytime before I ask a stupid question
