Like I said, that was my one and only experience; I know hotrodders have been using it for decades. If it were me doing a sump, I'd use Techline's thermal dispersant coating (aids in radiating heat away from a component). It was handed down to the (aftermarket) auto industry via NASA's big push to technology transfer in the late 1980s, developed for use on the Space Shuttle. If it was good enough for them... I didn't intend to cause you any undue stress, get some other opinions on Glyptal before you abandon your plans.
Jon, I would just leave it as is. With the thoroughness of the work you do, I wouldn't worry about the glyptal lifting. The thermal dispersant coatings are typically used on the outside of the casting. While on the insides an oil shedding fluoropolymer is normally used. I think "mountains out of molehills" is what's being made out of the oil cooling issue. Italian castings were notorious for porosity and I would have sealed them up too. If sealing the castings add a few degrees temp, just offset it by using synthetic lubricants. The lubricants of the past needed those cooling fins, not so today. The Techline stuff is geared more to the diy/hobbyist. I would a racing grade coating. Like these: http://www.swaintech.com/ http://www.calicocoatings.com/index.phtml?coatings http://www.dartheads.com/dartc.aspx So you didn't like the idea of the Loctite 990 Impregnation Sealant for the castings? So when we get to the engine internals, are you going to go all out and use Diamond-Like-Carbon (DLC) coatings? That stuff is on level and price far above the vendors I posted above.
The gearboxes we used at work all had that coating on the inside. All made in Europe. They are all castings. Some areas would flake off over the years. With the greater thermal expansion of aluminum-i wouldn't trust it to stay adhered.
I've got Glyptal on the two case lids and no problems. I did bake them in a small over after I coated them but to date, no lifting, no clogs. A renowned restorer of Ferraris who helped me with my car uses it on his cars including 250 Cal Spyder, 750 Monza, etc with no problems. Bake it and forget about it. Cheers...Keith
Doesn't baking help during set up and OMG is past that stage. too late. I'm with Corbani on this one, this application was unnecessary and over the top. The downside is far worse than the upside - I could live with oil drips but you don't want clogged oil passageways.
Sorry to have steered you in the direction of Glyptal. I don't think you can go wrong either way but in the end, if it is a concern for you, nix it.
After all that, I'm going with the Glyptal. I'm working on the oil filter assembly and oil cooler. It seems a shame to paint the oil cooler black, it's a piece of art. Image Unavailable, Please Login Image Unavailable, Please Login
It looks like you have some copper crush washers in those last photos you posted. Some people say you can heat up used crush washers (red hot), drop them in cold water and then re-use them. I've tried this with bad results. Replace all of your crush washers if that wasn't already the plan. That's an easy way to prevent a typical source of leaks.
Since you have not decided to concours your car, then painting or coating the oil cooler is your decision. Having second thoughts on the concours decision? You are there already and an example like yours might be in the top ten of the world, probably a quarter mill before long...
OMGJON, What an incredible restoration! Maybe I missed this, but had you owned this car for a long time before this? I am surprised that you didn't use a "rougher" specimen since you planned to restore it in such detail. The car pre-restoration seemed to be in pretty good shape. Either way, this car is going to be amazing when you are done. I can't wait to see more pictures of it further along! Congrats on a great project!
It was the only one I could find at the time. I really had no plan when I got it to restore, just kind of evolved.
MMmmphf (biting my tongue...) Oh what the hell, you can just tell me to shut up if you want to Those halfshafts look beautiful, but did Ferrari put all the clamps in the same orientation? When I did some CV-Joint covers recently on a supercharged BMW M Coupe, the TIS said to alternate the clamps to preserve balance. As can be seen in the following pictures, the Otiker type clamps on the BMW axles are of even less mass than yours.

It probably doesn't, but you know how those Germans are; nowhere near as passionate as the Italians about things lining up On another note, whenever I service the axles on one of these cars (the German ones) I return them to the opposite side of the car. A tip I was told, in an effort to extend the life of the CVJs, as the load is now on the opposite sides of the cages and hubs (plus we have splines to deal with too). It's looking good Jon :thumbup
Jon, Since your engine is out of the car, have you found the engine serial number stamping? I'm having difficulty locating mine and appreciate any help if you've found your engine number. Kind Thanks http://www.ferrarichat.com/forum/showthread.php?t=114939
Jon, This is absolutely one of the best threads I've ever read, on any forum in my years on the 'net. I was linked to this thread from another, and had no idea going in that it was 40+ pages long. Of course, when larger, crisper photos started to come in, I got hooked, and I've spent almost the whole day reading. Something you said earlier spoke to me - that every individual part is a piece of artwork. I understand that completely and you're doing a fabulous job making every single part better than new before the car goes back together. I feel ashamed of the work I did in my teens to my Datsun 240Z - I rebuilt the entire suspension with coilovers and polyurethane bushings and didn't even repaint the parts before I put them back under the car. Every piece you've shown us is like an individual jewel. I'd be honored to see the project sometime when I'm in San Diego, my hometown, but I don't know if you'd want me around. I'd just be staring around gibbering and getting in your way, and not adding anything useful to your life Now that I've finally made my way to the end of this thread I'm going to be really impatient to see more pictures of how things are going!
