Drilling Crankshafts
So many shops skip this super critical step in overhauling an engine, drilling out the crankshaft plugs and cleaning the oil passages. Some people think that is should only be done when a crankshaft has been ground or polished but we drill out every one because you never know what could be in there. The oil inside the passages gets thick and contaminated with grit and will either plug the passages or release into the bearings causing rapid wear. An example of how thick this sludge can be, imagine the the drill bit spinning easily as it cuts through the steel plug only to stop once it gets through the plug and into the sludge!
We charge 10 hours of labor to remove the plugs and properly clean a Ferrari V-12 crankshaft so for under $1000 you can feel confident that you will not ruin over $1000 in rod and main bearings and all sorts of other potential premature wear and headaches.
We just got into an engine that had major wear to the main and rod bearings and found that someone had ground the crank to the second under size but never cleaned it out so within 1000 miles the journals were at the 3 under size! We sent the crankshaft to be built up to the standard sized journals and after cleaning and plugging the passages, she will be like new!
Porsche 911 Rust
My customer was explaining how the front end of his 1968 Porsche 911 felt loose and made some odd sounds when going over minor bumps so he wanted me to take a look at it. I found more than just a loose tie rod end, I found a major problem with the suspension mounting area in the lower front pan.
This is a rust prone area because the battery is located just above the right front suspension pick up and as it off-gases, the steel rusts. It is also an area for moisture to collect without an area to drain or vent, an area impossible to protect with paint. This is why the more modern Porsches with the fully galvanized frames are so great because all of the hidden areas get protected as well as the body work.
I stripped all of the front end out for the car including lights and trunk contents and hoisted it up on the fork lift. I sandblasted the entire area to see where the rust stopped and the steel with integrity started and went to town cutting and replacing the metal with cheap and available stamped steel panels. We do not have the Porsche factory capability to spot weld these parts to the car so we use an 1/8″ drill to re-create spot welds with the MIG welder. Once finished and under-coated you could not tell where the repair started and ended.
After spending so much time working on one-off Ferraris with no commonality or available parts, it is so refreshing to drop in a piece of sheet metal and stitch it in as we did on this project.
Ferrari 330 GT 2+2 for sale

We sold the 2 headlight 330 but have another car in the shop to replace it. This car is in our shop for service and is for sale for those of you who are interested. It has not run for many years but has healthy compression and has everything to make this a safe and reliable car.
The car had an incorrect master cylinder and booster so I located the correct parts and had them rebuilt along with the calipers. We installed new brake hoses and new clutch hose, clutch hydraulics and reservoir hose. The radiator was re-cored, carburetors rebuilt along with a host of other details to ensure safe and reliable operation for the next owner.
We also assembled the car after it was painted years ago. It was a struggle to locate all of the parts in various boxes but the car is complete and really looking good. I like the very original interior because everything is just right.
This is a very late 4 headlight car with a 5 speed and factory (dealer installed?) air conditioning.
