I'm happy to report my 456 valve guide rebuild is almost finished. I had the day off, so a friend and I took the Piper Cherokee up to Denver to...
All of the above. Many (most...) parts are interchangeable in the drivetrain/chassis. Wheels sizes and offsets are identical, in particular.
The only fix I'm aware of is to strip the rubber coating and re-paint the component. Check the 355 section, those guys have a dissolving-interior...
Check my old posts for many details. Here's a start: http://www.ferrarichat.com/forum/showthread.php?t=131243
Yes, my smoke was *white*. In fact, I was in denial for several hundred miles, and did things like hold a mirror to the exhaust to look for oil...
This was the behavior of my 456 prior to the increasingly-strong smoke, which eventually reached dense, white smoke on startup. Mine started as a...
My valve guide problems are a fairly isolated case. I know of only 2 other 456s that have shown this problem. If you're looking at a car, have...
I have direct experience with this issue and my car is currently in the shop (Ferrari of Denver) with leaking valve guides. The facts of my case...
Why no stories? These cars have a small number of known problems; I'd rather by a car with a "story" that these items have been identified and...
a couple of more items to check... Steering racks/front shocks get a workout with these heavy, front-engined cars. I'd open the rack boots and...
Now, now, you don't like the very-rare, very-limited Superman-edition Ferraris?
At $100k, you're about $20k shy of a good, documented 550. Plus, that leaves nothing for maintainence. I'd say a 97/98 456 6-speed for...
Interesting poll results. About 10% show valve problems. I would suspect, this number is over-reported in this venue, since folks *with*...
Not bad on my 456; a bit more modern looking than the stock 17" jobs... [ATTACH]
Yes, I have a valve guide problem in my 2000 456M (same top-end and cause, worn bronze valve guides). See here for all the gory details....
Let's see, 2007 M5 MSRP is $82,500. $60K depreciation in the first year? Please point me to any one-year-old M5 selling for $22k. I'll buy...
Good read. Interesting that the subject 550 also had a valve-guide problem. The more you dig, the more you find the modern V12s have the same...
I've switched. Several times. I currently have a 2000 456M, now in the shop for leaking valve guides at 24k miles (see the 456/550 forum for...
They don't. Look closely, the first photo has the piston near the bottom of its stroke. You're seeing reflections against the (thankfully,...
A bit more info on my 2000 456 (24K miles) which has experienced a rapid-onset case of smoking/burning oil. Search my previous posts for a more...
