Rebuilt engine smoking on start up

#1 Post by Ltriumph » Tue Nov 26, 2024 11:18 pm

I had the engine rebuilt by a professional rebuilder (Triumph 2000TC, 1978), on start up it smokes white smoke. They said it as condensation being winter but the car is garaged and it is coming on summer now and still doing it. Have done about 1500km since rebuilt. Any suggestions why or is it normal?

Is the coolant level in the radiator (more important than the level in the so called expansion bottle!) remaining constant or is it dropping and requiring regular topping up since the rebuild?
Has the cylinder head been retorqued since the rebuild? Triumph engines should be (I can't remember the mileage but it will be in the handbook / workshop manual). Modern engines with 'single use' stretch bolts don't need to done, but Triumph 6 cylinder engines do.

Hi,
Definitely not normal, like johnnydog suggests, water getting into the cylinder(s) giving you steam in the exhaust. What was the reason for the rebuild - Anything that might have resulted in a cracked cylinder head ? A hairline crack can be barely visible and may have gone unnoticed by whoever rebuilt the engine, but might explain the steam.
