This was in my friend’s b16 with ITR cams, skunk2 valve springs and ITR retainers. Head was rebuilt 4 months ago. It happened at 4k rpm



Was this an install problem or just spring frailer? Anyone else had this happen to them?

 

Me too!

skunk2 valve spring do break a lot they are not all that good i have crower premium valve springs and i have no more problems and got Titanium Retainers for my ls, i talked to alot of people and they all told me that skunk2 suck a$$

 

man you guys dont need to be showing me this, this is not good for my eyes, I have a fully built GSR with Skunk stage3s with full Skunk valvetrain, makes me scared now, but I dont have $$$ for new valvetrain right now, trying to buy a new header first, damn YOU

Buy RM valvetrain and there will be no more problems....cheap insurance!

 

What was the install height. I say this everytime I see a broken Skunk valve spring. They have next to nothing in terms of room before coil bind if installed at what skunk recommends. Also what retainer was used?


Anyway, I feel Skunks springs are way too tight for most big lift cams out there. That is just my opinion. I ran them with Toda C's 12.5mm of lift at one time but was always nervous. I installed them with a taller height than what Skunk suggested and still only came away with .045 before coil bind. .060 would be ideal. So running them with Skunk3 stage 3 cams which lift 12.8mm I think as to be scary.

 

I was running an stock type r intake cam and i was also using itr retainers

 

THe stock ITR retainer does not fit as snug as the Skunk retainer does against the valve spring. Perhaps the resulting harmonics from this is what expedited the spring failure.

This is purely speculation.

So it seems from what has been said in the past before about other manufacturer's valve train pieces that RM might be the better safe bet than a sorry one?

 

Yeah, RM's valvetrain handles 13mm of lift and still gives you the coveted .060 clearence before coil bind.

 

omg. you guys are scarying me.. i was just about to buy these..

so what else is good?

i was planning to run skunk2 pro 1 cams with pro 1 cam gears + skunk2 springs/retainer.

so if those springs break.. i dont think i wanna pick those up.. what springs/retainers should i use to go with my pro1 cams?

 

Everybody sayd Rocket valvesprings are pretty damn good, guess you cant go wrong there if HT people swear by them.

I think its been mentioned a couple of times already in this thread, but Rocket Motorsports make a great valvetrain.

 

If Skunk2 valvesprings are crap then supertech valvesprings must be crap as well

 

This is probably why Skunk cahnged their valvetrain.. Skunks new stuff (pro series) is brand new and different from the older stuff..

 

hey grenthang what kinda valvetrain you movin to this time? goin with the RM?

nice, are they still linear and whats the seat pressure?

 

I say spring failure! The Skunk 2 company isnt known for its quality of work. From my experience they make more crap than quality parts!

Skunk2 =

 

What about eibach spring are they any good? Cause I got those instead of sk2's

Elaborate with some cold hard facts please.

 

in skunk 2s defense, based on personal experiences, i snapped one inner spring on my head and didnt know for 2 months. i beat the **** outta that motor, even dyno tuned it, and i didnt bend the valve at all.

and skunk2 was good about replacing the busted spring too.

not making a general statement on skunk2 products, but in my experience it was pretty good
