C5/C6/C7 Engine Cleaning

Whether prepping your Corvette to roll across the auction block or display at a show, cleaning the engine adds value. A spotless engine shows just how important and well maintained is your Corvette. Filthy engines are more apt to retain heat and make it difficult to detect small leaks. Dirt and dust cause pulleys and belts to squeak from undue wear. Worst of all, it just looks bad. (more…)

C3 Radiator Core Support Installation

lead-shot

The radiator core support has two functions: radiator placement and front end support. Weakened core supports allow the nose of your Corvette to droop, increasing the gap between the upper part of front fender and the door. When that occurs, stress is placed on the inner fenders. Before the core support project begins, a thorough inspection of the attaching hardware and cushions is in order. We’re working with a rough but fairly original car, so we were careful to save the hardware and as many O.E. pieces as possible. (more…)

Addendum: 1955-1966 Corvette Fuel Pump Rebuild

DSC_0079

In a previous article, we covered how to restore your fuel pump. Those were the days! Disassemble the fuel pump, replace the check valves and diaphragm, and you were back in business. I have always felt fortunate that when I started out in this business, engines had carburetors and emission systems were in their infancy. At the local GM dealer, we repaired or overhauled components to fix them, not just replace pieces. Oh well, those days are over. All I can do is share those early experiences and hope they help you get through what would otherwise be a trying situation. (more…)

C5 Oil Pressure Sending Unit Replacement

C5-Oil-Pressure-Sensor-Replacement-Lead-Shot

If you haven’t already replaced the oil pressure sending unit (CC part # 305254) on your C5 Corvette, it will become a necessity when the gauge stops functioning properly. One telltale sign is the oil pressure gauge needle leaning past the high mark at all times or not moving from the lowest point. Another sign is an oil leak near the rear of the oil pan. Many times, the presence of oil is mistaken for a leaking rear main seal; always look at the top of the bellhousing for the source of a leak. If there is a trail of fresh oil cascading over the bellhousing, chances are the sending unit is leaking. Sending units have an immediately noticeable leak, whereas rear main seals usually experience a slow leak that increases over time. (more…)

1955-1966 Corvette Fuel Pump Rebuild

CC5866FP (10) (Medium)

[ view the Addendum here ]

There was a time when a component would fail it would require repair or rebuild.  But today we throw it into the appropriate recycle pile. Growing up in the 60s and 70s sometimes makes it difficult to trash anything; today it makes more fiscal sense to buy another one. If you worked in a GM dealership in that time period, the philosophy was repair unless it had catastrophic damage.  Of course back then metal was used  for most components; plastics were for the occasional trim piece. One of the many repairs you had to perform at the dealership was rebuilding windshield wiper motors, distributors, alternators, starters and fuel pumps. (more…)
