sewing machine
sewing machine well had g5x4 cam installed last week I have that sewing machine sound I have Patriot gold's and 7.4 pushrods and stock heads. I spoke to LG Motorsports today about going to a 7.425 pushrod to see if this would help they told it was my gold springs doing this and they have a bunch of these springs that failed. I just want to know if this will hurt anything or just leave it?

I'd step up to the longer pushrod for proper preload. That'll quiet her down. As far as the Patriot Golds are concerned, they are a pretty stout spring. If you were trying to control large 2.08 or 2.10" aftermarket valves, I might worry, but with the stock valves, it *should* hold for a while.
well i have this same problem with my car except mine was the ms3 came with 7.400 pushrods and they said it was the pushrods being too short so i ordered 7.425 pushrods but there on backorder right now but when i get them in and change them out we will see if that works. o and its ok to drive like this nothing will get hurt.

I also got 60,000 miles out of a set of 918's with a smaller cam.
Take your pic they are all good springs, but the PRC's, Patriots and Comp duals will allow you to run more radical profiles and higher lift to .660...at least on stock weight valves.
Our Patriot Gold spring is the best spring on the market. They are a very high quality spring that performs great. We called to speak to Lou at LG about these "numerous" failures. Lou was not in but we did speak to the customer serivce rep who talked to you about this issue. We were informed that they have not used our springs in roughly 3 years. This would stand to reason that since our Gold spring has only been around about 2.5 years, that the spring that they are referring to is not our Gold spring. Search this forum and you will be hard pressed to find any negative comments about the Orginal Patriot Gold spring. By the way, you will notice that even our competitors have followed our lead and now use these springs...using their own name of course.

I run the Patriot Gold springs. These springs are very high quality and keep my valvetrain in check nicely at 7000 rpm's. I have no sewing machine noise that I can tell. Maybe I would hear some if I had a quieter exhaust on the car. I also use the 7.4 pushrods.
thanks for the input guys the noise doesn't bother me just making sure everything is ok oh and thanks gunnar for giving them a call I hate to see there customers get scared off a product that every one says is quality
What was the problem earlier on with your heads? I thought it was valve spring failure? There was a reason a while ago, there were some failures or something as to why you shouldnt buy patriot heads. ?

Hows the car doing Terry?
Yeah its weird some cars will have lots of valvetrain noise and some won't. Some only do it after warmed up and some do it up till they are warmed up.
I wouldn't worry about the springs. like Gunnar said they are quality springs. LG was just trying to sell you some million dollar springs. they will say anything to make a buck.
I'm glad Gunnar called them out on it though.
