Valve float is only damaging if your valve hits a piston.

Then you have problems.

 

but what if its making some goofy noise that i really cant explain lol, and has little loss of power, will it hurt to drive it to dealership or should it be towed over?

 

Your car comes with free towing to the dealer no matter what within 3 years or 36,000 miles

 

You sir are incorrect. While the LSJ is an interference motor, since the valves are at such a high angle, if you get valve float the piston simply pushes the valve closed, rather than break off the head. My pistons showed indication that the piston and valve made contact on more than 1 occasion. However on a push rod motor with low angle valves, piston vs valve = fuct motor

 

hmmm... General cobalt sounds good to me

 

actualy weather its a pushrod or ohc engine makes no difference if its an interference motor. look at a dsm, when you break a timing belt it bends half the valves. the piston doent simply close the valve, it cant.

in the case of valve float, it may just push the valves shut. however, if its running bad id say its got a bent valve

 

is there some where i can get replacement valves or even aftermarket ones for the 2.4 and i guess springs and all if dealership wont do anything with warranty for me

 

Ferrea is doing my valvetrain, custom length +1 mm titanium valves, dual valve springs good to 9000+ rpm, and titanium retainers

 

Jbody Performance...I was drooling all over the heads they have for sale there...I read your story...


Stop and think before you go to the dealer.

Ok.

You over-revved your car, it broke. How is that mechanical failure? Instead of getting your warranty completely denied, just file a insurance claim...seriously...you will get your whole warranty denied because you are trying to get a freebie...not wise...

 

note taken. what about police report though. i dont know if anyone called it in or not because no one ever stopped i mean the others who were almost involved did like i did try to slow down and avoid it but no one ever actually stopped. will that matter for insurance claim? by the way i appreciate all the help guys
