330GTC engine overhaul




A friend who owns a 330 GTC went with me to look at this blue GTC when I was interested in buying it. The seller claimed that in the 20 years that he owned the car, he never did much to it other than routing service, new shocks and tires. My friend who has spent countless thousands of dollars to make his great car nearly perfect said, "how can a car with so little recent work run and drive so well while my car has been such a struggle?"

I sold the car to a customer in February 2006 and he drove it 2000 miles without any issues but realized that is was leaking lots of oil and thought that we should do some engine bay detailing.
Before pulling the engine we did a leak down test only to find that 2 cylinders were very weak, 50% or more and all other cylinders were at 30%, not great numbers for an engine that started instantly and pulled strong! (But it burned more oil than it leaked)

We found one of our favorite scenarios, an original engine that has not been puled apart and messed with by someone who did not know what they were doing. We overhauled the engine with new forged pistons, all new bearings in the timing chest and crank shaft bearings. We replaced all of the horribly worn roller follower assemblies and did a major cleaning and detailing. From the second the engine first made smoke, it has run like the champ that it always was!

We cleaned, re-painted and detailed the engine bay and renewed all A/C components so the car worked and looked as new. Later this year we will replace the yellow SALVA hose and re-plate the hose ends and ferrules.
The photos show some before, during, and after shots.
