348 Engine blew 367 days after last major...

I was thinking more of Luca complaining about being clipped by a GTI. If that story is true.

 

So all you red liners, just where are you driving that you can hit red line consistently in anything but 1st gear? I see a lot of You Tube vids with guys going through the gear and I pretty sure they aren't taking the car up to 170 mph.

Estimated MPH @ red line

1st 53
2nd 75
3rd 101
4th 128
5th 157
6th 194 (exceeds stated top speed of car)

 

Throw a Chevy LS6 motor in it like all the gearheads seem to do with everything these days. Just think of all the talk you'll get at the next Ferrari meet you go to. and


Sorry, just trying to throw some levity at a bad situation. All the best of luck getting it sorted out.

 

Only certain aircraft used for as hired has TBO dictated by hours.

 

Exactly what I was thinking. I’d be very suspicious if I were the OP.

 

Can’t help ask...
1) are the teeth on both belts stripped or just one?
2) on the bank(s) where the teeth on the belts are stripped did all of the valves make contact with the pistons? (Can the inlet and exhaust valves physically make contact; I don’t know hence asking?)
3) does the crank freely rotate?

Obviously further info required and unhelpful speculation on my part, but could this be oil starvation to the cams? Because as described the only thing that will rip the teeth from the belt if either crank turning and cams not or visa versus; the latter not being possible. I’ve seen it in a four pot years ago where it was a bit of rag clogging an oil way that starved the cam of oil and it seized.

I don’t buy the over reving arguments as there is a safety factor on the redline anyway, this would only really apply if you were down shifting or seriously missed a gear and some how forced it into a lower gear. (almost impossible) and presumably the first issue would be valves bouncing, which doesn’t logically lead to teeth being stripped, or does it?

Be interested to see the pictures and hope you get a logical and not horrendous $ repair.

 

On a separate note how was it with the refreshed steering rack. On mine it changed the character of the car completely.

Your numbers look 5% higher than actual.

Areas around me, if you aren't doing 95 on the expressway you're getting passed.

Late night, early morning with no cars on the road it's easy to go fast.

Even if you just run zero to 100 that's still redline shifting 1-2 2-3 3-4 and getting there a LOT faster than lugging the poor thing like a diesel

 

Calculated from gear ratios and tire size at 8700 RPM. But the point is you can't go out for a 4 hour drive and be hitting red line at every shift or you will never get out of 3rd. And what's with the expressway? What fun is driving on an expressway with a sports car? I can do 95 on an expressway in my Toyota truck. I'll take the curvy back roads of NE at 60 over an expressway at 95 any day.

All the information is in the thread.

One of the buckets popped out and seized one of the camshafts.

Two teeth and the valves are into the pistons, the engine is done, there will be significant damage.

The crank should not be moved in this situation with the teeth stripped, you really do not want to do that.

No way oil starvation would make one cam seize. Or have anything to do with the bucket dislodging.
Its likely been over revved, but not by the OP, seems logical to assume at this point whoever road tested the car after the last service likely went 1st-2nd-3rd-2nd....something like that.....
If you are a buffoon, you'll get into the wrong gear!!

I am interested to see some pictures....

 

I got 5% less than what you did calculating the same. What's with the expressway is I drive on more than one road, lmao. Lots of curves and ramps everywhere anyway.

Didn't say I'm "redlining every shift" but when the opportunity presents itself for max acceleration I'm using all of the rev range.

 

Its not about hitting the redline in every gear, and I suspect you know this. Nobody said anything about "constantly" hitting the redline.
Where opportunities present, I'll use the full RPM range and power the car has to offer, why wouldn't I? Totally within safe operating margins, it designed to be used like that.

I run my car to the redline often in 2nd and 3rd when we are out on drives in the back roads, but not EVERY shift is at the redline, I fail to see how this is so difficult to understand......

I don't think about "numbers" and "oh my I am putting 50% more stress on the engine taking it 1000rpm over 6000rpm" and so forth......I just drive the thing to how it feels, there is one of the best exhaust notes, and plenty of power up around 7000-7500rpm, and I'll use it thanks very much, just like Ferrari expect we would.....

But at the end of the day, I respect how people want to drive their cars, but it seems silly for those of us that like to run to the full potential the car has to offer, that we are being made to feel like we are "risking" anything untoward.....
If we were bypassing the rev limiter and taking them out to 9500rpm beyond the fuel and ignition map, then of course, that would be very risky.....
Working on the south side of the rev limiter, happy days, live and let live......

 

The 'timing' of the service and 'mayhem' is too much of a coincidence. Maybe BIG coincidence, maybe a small coincidence, but still, a coincidence.

god I love Seinfeld


.

 

And that's the bottom line. Drive like YOU want to. That's what I do. I bought the car for me to enjoy, not to live up to someone else's expectations.

 

Would be interesting to know the mileage of the OPs car.....more miles=more wear.

 

Don't even know where to begin with that one. I'll say this, these cars don't just grenade with miles.

Generally no, but could be a factor. Just curious.

 

Well, if you read the thread carefully you will see that it's been 1 year since the major service. I highly doubt he exceeded 30,000 in the span.

 

It’s a Ferrari, they break, that’s what they do. Lovely automobiles, great sound, but poorly engineered and rubbish build quality. I feel very sorry for the owner, but you have to be a masochist to own these cars, it’s the price of entry.

 

Build quality perhaps yes. Poorly engineered though?

 

How about questionable engineeering decisions? Companies like Hill Engineering are thankful.

 

I work on my 355. This is very true.

 

Ever been to Italy? The whole country is like that. Questionable engineering and decisions. Ever hear of the Morandi bridge in Genoa. Fell down in 2018. Very questionable engineering and decisions. Ever been on their Fast train . Has to slow down while passing towns. Not so fast. It's called the Italian way. Ferrari is no different.

 

Be careful when you start throwing stones.....
