the worst experience I had on the track with my 512 BBi was the only time i took it out in the Ferrari National meet in Atlanta, 1989 or 1990. The glare from the dash was unbearable...also had trouble seeing the track coming up a hill with a quick drop ( especially an S) i guess once you learn the track, it is no longer a problem.. | ||

Cliff Welcome - For my mondial I use Bryan at independant as well. I am looking for a 512. I guess he has experience working on yours.  | ||

First, glad you are all out there. I recently traded my 328 for a 512BBi. I had the interior completely redone (Coachtrim in Stamford, Ct., did an excellent job) and my mechanic (Independant Motorwerks, Short Hills, NJ) is replacing wheels (17" SLCompetition, tires (?), springs and bushings. I would like to use the car at FCAand FOC track events which I regularly participated in with the 328. Can anyone give me some idea as to what to expect on a track (Watkins Glen, Summit Pt., Limerock) in the 512? Also, any suggested mods for this purpose. I have always driven my Ferraris regularly and will do the same once the Boxer is returned. Thanks. | ||

and I bought them prior to 1990; 2 daytonas, l boxer, l 86 TR and 1 79 308. Loved them so much couldn't sell. Thanks Steve, I'll check with those Jetronic experts. | ||

Coach i -- I checked the amazon books again and Audi and MBenz brands are also included in the K-Jetronic application lists. Five? -- you, sir, are a masochist (I can only handle one dominatrix at a time ). | ||

Steve, thanks for the reply. I did check both injectors, after I removed them from the manifold, by turning on the fuel pumps, even cranked the engine, both connected and disconnected, no fuel came out as the car was warm and none was needed. I hopefully correctly eliminated the cold start injectors. I haven't messed with the plungers yet, and that would be my next project. The VW mechanic might have to get involved. Ferrari problems, probably all car problems, are so aggrevating, but then I don't drive my cars ( I have five ferraris) much, so then, if you don't use them you lose them...despite being garaged in an airconditioned, heated garage. Again, thanks for the help | ||

Coach i -- When you took out the cold start injector was the system actively pressurized (i.e., the fuel pump was running)? Electrically disconnecting the cold start injector wouldn't prevent it from leaking under pressure (if it was) -- it would only ensure that some electrical fault couldn't be wrongly turning it on. You could also try swapping warm-up regulators to see if that's the problem (and if it moves the problem to the other side). Have you "felt" the relative motions of the 2 airflow meter plates (engine off) to see if they're mechanically different (i.e., stuck control plunger)? All the Bosch books on K-Jetronic usually have VW application examples so a local VW shop may be able to help as well. | ||

Steve, this is Bosch K Jetronic. I took out the cold start injectors, and they are not spewing gasoline as expected. The problem now is serious as gasoline is dripping from the low points of the exhaust, so there must be a large quantity of it going into the manifold and pistons. Something is telling the fuel pumps to pump lots of gas and the fuel injectors are happy to accomodate. I have even disconnected the cold start injectors and the car starts fine and runs well, but the gas keeps pouring out. Help.....anyone, thank you. | ||

On the testarossa Bosch system, there is a relay that actually allows for extra gasoline to enter so that the car can run. This older Bosch system is definitely different...and something is stuck... I'll look into that, thanks Steve | ||

coach i -- sounds like an overrich condition from the right bank injection system (since like you noted the spark system is shared by both banks) -- cold start valve stuck open, warm-up enrichment device not working properly, etc.. It is an injected '83 right? -- is it K-Jetronic? | ||

well, I changed the oil, the old oil had lots of unburned gasoline in it. Both exhausts continued to drip unburned gasoline, even new gasoline. The car ran fine, but there was a tremendous amount of unburned gasoline, i checked the plugs, the left bank is dry, the right bank is very very wet. How can that be? There is only one coil and one distributor on this car, and the spark plugs on the wet bank are sparking-- not a very hot looking spark though... anyone have any suggestions? My nearest Ferrari mechanic is 120 miles away, and it is a lot of trouble, time and expense to take car there.. | ||

I have a lift, i'll put it up there, siphon the fuel out with a simple tube, till empty...at the same time change the oil and filer.. will atempt this tomorrow... will let you know the outcome.. thanks for all the suggestions | ||

Well, that's a good question... I've done it a couple of ways... 1) Remove the fuel return line (that goes back to the filler neck) and turn the fuel pumps on. Easy on a carb BB, no so on a f.i. car, but possible. 2) With the car on a lift, remove the "plug" on the fuel tank cross-over tube. (This can be challenging to get out...) 3) Use a cheapo plastic fuel siphon pump.. Not my favorite job....and potentially very dangerous. Hope this helps | ||

True, I did not empty the tank completely before I refilled the last time, and the gasoline was awful, also there is some gasoline smell in the oil... I will change the oil, drain the gas tank, and start over again. What is the best way to drain a gas tank, suggestions please | ||

I've have a 74 365BB for 20 years now, and have had various types of exhaust smoking issues with it through the years. I, like you...have very few miles on it, and drive it infrequently. Looking past the possiblity of any major engine problems, here what I have found to be the typical causes/solutions for the smoking. 1) Fuel contaiminated olio-Pull the dipstick and smell the oil...If even a remote fuel smell, change the oil. 2) Boxers exhaust crosses over...Right bank exits on left side, Left bank on right side...Seems obvious, but can send you in the wrong direction when diagnosing a problem. 3) Pull "all" the plugs...It just takes one bad/partially fouled one to make big smoke. Look both at the spark plug tip...and the shoulder for oil/abnormalities. 4)Although this affects both banks, old fuel remaining in the tanks doesn't help matters any... Been down this road a few times... 5)If all else fails, get the car on an exhaust gas machine... 6)Unlikely, but possible..Check the CO level in the coolant overflow tank. If you have a headgasket seepage problem, the plugs can still look "OK", but there will be trace amounts of CO present in the coolant. Hope this helps... David | ||

well, i don't think the seating of the rings is the answer. I started it again today, ran it for one hour, and quite a stream of liquid was coming out of the exhaust, almost smelled like gasoline, or old gasoline (I have just filled up the tanks) and it continued to smoke. It smoked only from the left bank, but the right bank exhaust mwas driupping that sooty looking gasoline. I am not getting worried... I checked the plugs, and they seem to be as dry as as could be...help..... | ||

The water you are seeing when you first fire up your cars is water condensing on the inside of cold exhaust system walls. some solidified cabon flakes off the walls and is suspended in the h20. water is a normal by-product of combustion and is always exiting your cars. its just when your exhaust heats up after running for a while, it passes through normally and doesnt collect on the sides. water is a small percentage of exhaust. one gallon of gasoline does not produce one gallon of water. heres a hint: dont stand behind your car and rev the motor manually. you'll end up dyeing your khaki's black right below your knee.

makes a lot of sense, rings need to be seated, not driven enough...I will make every effort to drive the xcx#@@@ out of it, see what happens. By the way, I had to replace the fuel tank sending unit, it was rusted throughout and the wire connections were broken off...Thanks for the input | ||

I have a 1979 BB512 which just had a complete rebuild. It is now in the period of breakin and seating the rings. It does all those things (smoke, water, soot; no oil). The engineer (Tate Casey, Carobu Racing) who rebuilt it says it will be that way until I drive it enough to seat the rings. I am forced to drive my car often to make this seating happen. Just drive the #$%!@ out of your car and it should be fine. Lee | ||

Edward is correct. I had my BB for 21 years and it always spewed water when started cold. I often wondered where all the stuff came from. | ||

What are the odds that on a car driven that little (265 or so miles per year... 22 miles per month!) the rings were never run in enough intially to seat properly leading to the oil smoke? I have seen that with E-type Jags that had very low mileage and were never really broken in. The rings never seat and the cars smoke. | ||

It probably is water. Your engine produces one gallon of water for every gallon of fuel burned. That is why mufflers rust out so often on cars driven only short distances as the accumulated water does not have time to get hot enough to exit as a vapor. This is also why most 308 Ferraris get the black soot particles on the rear body panel. | ||

just noticed that my 83 Boxer with less than 5000 miles.. when started, the left driver side xhausts smoke and continue to smoke, and the exhaust drips some liquid, not oil, but more like water with soot in it... any ideas ? |
