Is the broken valve sping excuse getting old?

May be...

Yes

you would think if that had that many broken springs, they would come up with better material. How about blame it on stuck lifter, broken timing belt, spun rod bearing, broken connecting rod, broke oil pump (dry sump of course), it's not like most people will understate what those parts are anyway.

So you want them to lie to make it more "colorful"? Do you think there making that up?

I don't think you understand what valve spring's do. When a valve spring breaks, the valve keepers fall out and the valve drops inside the cylinder which then mushroom's or breaks the rod not to mention pops a hole in the piston because the piston can't compress a huge chunk of metal. i.e the valve.

Spring rates and pressures are very critical and fined tuned to the lift and duration of the cam. There the most stressed part in any engine.

If I was the valve spring I would hire a lawyer and take the teams and the drivers to court for slander. The valve spring should also sue the motor oil and the carb that pushed so much fuel into the engine. The valve spring gets no respect what so ever.

Every time an engine blows, they try to say it's a broken valve sping. Of all the parts in a V-8 pushrod engine, couldn't they be a little more "colorful" and blame it on a mushroomed pushrod, seizure from heat, lubrication failure etc., instead of blaming it on a valve spring?

Maybe they need to change the rear end gears so they run so high of rpms....It,s just a quick excuse..

Faulty valve springs from the manufacturer, are a common problem..
I suspect, the lack of test laps this season is responsible for many
of the problems the teams are having, including the pit lane problems..
The less experience the team has with with a shipment of any part, the
less likely they are to uncover a fault, or weakness..
Valve springs are just about the weakest link in the valve train..
They are complex, mechanisms that can acquire microscopic flaws during manufacture.. This can result in catastrophic engine failure..

I agree with whatever you think because I know it is right and your crystal ball is amazing too. The valve spring excuse is getting real old in Nascar, I agree with you.

Honestly I think it is really a cover-up for teams that are experimenting with trying to get more power because of the limited testing doesn't allow time to try new things in practice so they have to sacrifice team members in actual race conditions.

I actually haven't heard that it was valve springs from anyone but FOX. It may be what some of the crews are saying, but you never know the real cause. It could be that one supplier makes most of the valve springs for Nascar teams, but seems unlikely that the problems would be this common for back to back races. I do know that Fox said that Mark Martins engine this week and JR's last week happened because the transmission jumped out of gear and the engine overrevved. Guess thats a possibility, but I have a hard time believing those engines would blow in a matter of a couple of seconds a good driver should take to notice his tranny is out of gear.

A failed valve spring is the most common cause of any push rod engine coming apart. It's called the root cause. They take a tremendous beating and any flaw, as is common in manufacturing, will weaken them. A broken valve spring is what causes a mushroomed rod. I have seen countless engines blow up as a result of overheating and it being reported as such. As for lubrication failure; Many times I have seen an engine fail as the result of an oil pump failure or something else going awry with the lubrication system. And heard that reported many times as well. So how about we deal with some reality? And they don't "always" blame it on a valve spring. Rash generalizations are dangerous and ignorant. Peace y'all

Seems to me there is something else contributing to the engines overrev. Juior last week, Matt, Mark, Jimmie and I forget who else this week.

A few of them had their transmissions pop out of gear, resulting in overrev, two laps later, blown engine. Yeah, broken valve springs, but the transmissions popping out of gear caused some of them.lt776s
