I read once that that line ad-libbed.
Apparently while filming the guns being used kept jamming on set so they came up with the line to account for it.
I would hear sloshing noises coming out of the engine compartment and heater coil.
Never saw any white smoke coming from exhaust.
engine temp never really changed until close to the end.
I think the sloshing was probably caused by engine gasses leaking into the cooling system.
Otherwise it was a great looking very smooth running and riding car.
Maroon/maroon with this awesome looking metallic flaked rubber door trim that i didn’t see on a lot of other Supras.
5sp turbo.
Same happened to my 87.
Head bolts were not torqued down tight enough out of the factory.
Sad part is I actually had the valve covers off while replacing the gaskets and the bolts were right there in front of me.
If I had only known..
