Thanks for all the good comments and such. I do plan on baking all the painted pieces in a large walk-in oven tomorrow. I finally finished doing the crinkle finish on the intake tubes, and will fog on the silver top coat tonight or tomorrow morning. The crinkle is not perfect, but good enough for my "driver" car. When I painted the exhaust with a ceramic coating I did have to bake at a high temp. as Jim Avery stated previously. Again I used the large oven at work on a Sunday when nobody was working, and cooked them at 600F for about 3 hours. It turned out great, I posted pics and stuff when I did that job and it's in the archives somewhere. The only thing I can't heat up is the engine block. That will have to wait until I fire it up. So till then I'll have to work carefully. | ||

Hi Jim, Yep, Jeff and his "new buddy" Henry surely win the Ambitious Owners Award for the Year!!! Frankly, I love their attention to detail and desire. When I did my BB engine overhaul, this board was my motivation to do a "cosmetic overhaual", as well. Going back to the paint issue...If Jeff is using VHT 550, the paint cures at 200F, on the engine...or in an oven, if possible. However, 550F is the max temp for the paint before it ???? David | ||

David, that's interesting. I wondered because I saw some high temp paint at store that had to cure at some rediculous temp (like 600degF)and required an oven or long run of engine to cure when first started. Just thought I would flag that for Jeff so he didn't overlook it. He has a lot on his plate, eh? Jim | ||

Jim, The VHT paint I used on my BB engine cures at 200F...So, once the engine is run up to temp, the paint is hard and solvent resistant.... David | ||

Jeff, Don't you have to cure the engine paint? How do you plan to do that? Just something to think about given all your hard work it would be a shame to run your engine and have it start peeling off or something. Jim | ||

Henry: I'm still waiting to order injectors pending an unforseen house repair, but will surely order them by this Friday. I'm getting them from Hal Rogers, a source mentioned by another fchatter. I do not believe the o-rings are included for the $21 price. | ||

Henryk, You mention "a common reference point" I don't know if this helps, but here's some data for testing injectors using your tester (it looks like a Bosch tester :- To check for blockage connect an injector valve to the tester and move the hand lever slowly (about 2 seconds per stroke) back and forth with the stopcock on the pressure guage open. If the pressure does not reach 1-1.5 bar over pressure the injector has a leak probably caused by dirt stuck in it. To test the opening pressure (2.5-3.6 bar) close the stopcock and operate the lever several times in order to bleed the injector, then open the stopcock and check the the opening pressure by operating the lever about 2 seconds per stroke. To carry out a leakage test open the stopcock, build up the pressure slowly to 0.5 bar under the opening pressure determined previously, but not less than 2.3 bar over pressure. No drops of fuel must drip from the valve for the next 15 seconds. To check the spray pattern move the lever faster than before, about 1 stroke per second, look for an even atomised spray with an angle of about 35 degrees. Hope this is of some use MW | ||

Jeff: I am trying to figure out the tester. I have instructions, but a couple things are not clear. I will have to get a couple of new injectors, just to get a common reference point. Where did you buy the injectors at $21?.......how about the thick donut O-ring? Enclosed is a picture of the tester.  | ||

LOL...nodding in agreement !! I heed your advice Henry....I've always been a perfectionist. I've been thinking about it, and decided I will try one more time on the intakes with crinkle, I now know what it should look like while still wet, to get the proper finish texture. The restoration shop people I've talked to say it takes two or three times to get it right. It's true I'm adding very little value to the car. But I plan on having it for a while, and when I pop the hood I want it to look good. Once the intakes are done, detailing the rest of the engine bay is a cake walk by comparison. The frame members are easy to do, just control the overspray from getting on other objects. And once done I'll be kinda proud to show it off. It's always better to work on a spotless engine and a dirty one. My previous cars (Vettes) were all nuts and bolts perfect, and it's hard to accept this car - a FERRARI - to be anything less. How is your injector testing going? | ||

Jeff: Sorry to hear about the paint problems. You and I have the same problem......we go TOO DAMN FAR!!!!!!!!!!!!!!!!!! I HAVE to hold myself back...as do you. After reading your posts, I have decided to just clean the engine, and spray some cheap aluminum paint on it. Same with the gray paint on the intake. While everyone commends us on our work, we have to be careful. Why spend money on this and that, when while it looks great, it really doesn't add to the value. When I had my car for sale, NO ONE asked concours questions.......they ALL had an idea what the car is worth. Of course, one can argue that one is doing it for oneself. Well, true, BUT one also has to be practical......we CAN'T drive the car while looking at our new painted engine.....it will still drive the same. Besides, there will be other problems that arise, that will need money to fix. Remember, we will be doing this in another 30K miles. So, don't get carried away. BTW: If the intakes look bad, I would remove the paint...I think this will be a must..... and just pray a "close" gray on them. Remember......DON'T get carried away. | ||

I have a question hopefully someone out there can answer: When I sprayed the crinkle paint onto the intake plenums and tubes, it did not come out satisfactory. Do I need to strip off the paint to try again or can I simply do another coat over the top of it? If I have to strip them down to bare aluminum again, I am NOT using the crinkle paint. Instead I will just use regular aluminum paint. Any thoughts? | ||

Henry: From what I've seen, looking at very low mileage original cars, only the intake plenums and tubes are the funky gray/silver crinkle finish. Prior to doing all this, I just cleaned my engine up real good and the bell housing was plain bare aluminum with no finish at all. I did originally just paint the engine block leaving the bell housing bare. It looked just awful, so I then went ahead and painted it too. I may not be "points correct" but oh well, my car is never going to be a show winner anyway. If you find out anything different about engine finishes, I would really like to know. | ||

Jeff: While my engine block and heads are silver, isn't the clutch cover (as the intake) a gray? It appears your clutch cover is silver.....maybe the light. | ||

It's been a very blah kinda day, with occasional rain and drizzle. But the kind words and encouragement from all you guys really cheers me up! Thank You All Very Much! Henry...there is an ending to detailing, I hear it's a mythical enchanting place to be. I don't imagine I'll ever get there with this car of mine. | ||

"...but now you have to remove the engine off the frame, and do it also..." au contraire, henryk; if I was in Jeff's shoes, I'd call it "Now I get to..." Every moment will be worth it. | ||

I finally painted the engine block and refinished the cam covers. The covers are just "sitting" on the motor for now, but they serve as dust covers while I'm fiddling around with other things. The red crinkle paint went on without any trouble. I heated the covers up prior to painting, and then followed the manufacturer's instructions. I am not so lucky with the rest of the intake plenums however. Since no silver crinkle paint is available, you must use gray or black crinkle on the intakes, and then fog on a coat or two of silver. Well the shape of the intake tubes makes proper application VERY DIFFICULT!! I was not totally successful the first time round, but will try again. It seems you have to put it on quite thick, almost to the point of dripping. I'm not posting pics of the intakes as they look awful. Per the paint manufacturer, no priming is necessary (VHT), at least that's what the representative told me on the phone. Oh well, the saga continues. I will keep posting pics for those that are interested.    |
