And here's some valve guide pics. So much fuss over such little bits. Can you tell the leaking guide from the pictures? I had to mic them to...
As promised, here's a couple of pics of the new rims and old valve guides from the 456 (rims first, guides shortly). Car is a 2000 456M with...
I'm very happy to report that I picked up my 456 from Ferrari of Denver yesterday after a 4-month repair for leaking bronze valve guides and a...
This is the best laugh I've had in days, thanks to FNA. How can they put something like that out and expect to be taken seriously? Did they even...
IMHO, the color and wheel style will have nothing to do with the overall mechanial reliability and ultimate ownership experience. Rather, inspect...
Your are mistaken. The emission warranty covers *only* those components as listed in the owners manual, which is usually, 1) the catalytic...
Some time ago, my 88.5 TR had a full-blown cat fire that took out the exhaust, bumper, and a good portion of the engine components. Ultimate...
I'm also a handy DIYer. My 456 developed valve guide problems, and after much research - including the need for some exceptionally expensive and...
More than late 90s. Present evidence is *all* of the 456s are impacted, up to 2003. What I find amazing is that even after the problem was known...
Well, not much good news here, but thought my 355 friends would be interested in some recent developments with the 456/550 crowd. Turns out, a...
Snow = 3 week delay. They outsourced the machining job, and I had Dave Helms consult for this as well. The heads came back from the machinist 15...
Great recommendaion. In fact, I had a long discussion with Dave about my car, and he went a step further and advised the machinist in Denver who...
456s are out of factory powertrain coverage (time) and still in emission warranty coverage. My inquiry on the emission warranty was greeted with...
This discussion is precisely correct, though the more accurate term to use throughout would be "offset". In the application with my rims, spacers...
Ouch. Sorry to hear about this. Your symptoms were same as mine: slight smoke to crop duster in a few hundred miles. I don't suppose you had a...
See my posts in the following thread for good pictures of the rims, spacers, Vredestein tires, etc. The spacers are likely the same ones coming...
Here's a set of cheapo 19" G-Force rims on my 456M. I've also purchased a very nice set of HRE wheels (19 as well). The G-force have spacers all...
IR temp readings of the exhaust ports are a time-honored method of diagnosing ignition problems. It really does work. Prior to IR tools, simple...
19'? Going mud-bogging in your 550?
Something to try I haven't seen suggested in this or your other thread. If you suspect you're losing a cylinder, get an inexpensive remote IR...
