Make a video and let us hear it.

 

I do know what you guys are talking about with the exhaust leak, it has happened to me before> I am like 99% positive that it is not a leak, but i will check that again. I did not soak the lifters they were not brand new, i had them in my 6.0 about a year ago so they have not been used since then. So that could be a problem. Also i have the comp 7.4 push rods with these lifters, I was told they work together?


I am going to try to get a short video up today so someone can hear it better, don't know how good my cameras mic is though.

 

Good Luck man, i had all those issues, loose rockers, then bad lifters, but they had 180,000 on them LOL. You did lock tite the rockers correct?

I just put a new set of LS7 lifters in my LQ4 im swapping in, i let them soak over night before install but its been a few days, so hopefully they arent noisy.

I bet you'll be fine after they pump up. Just take it easy till they do.

 

So i drove it today for about a half hour, took it pretty easy on it too.. Damn thing is still ticking loud as can be. Im like 99 percent positive that it is a lifter now. I am going to upload a video so you guys can hear it.

 

waiting for vid.

 

Video is at this link on you tube, thanks for all who are trying to help

Sounds like a spun rod bearing Here's another spun rod bearing on a LS1 to compare: http://www.youtube.com/watch?v=gRSrUQudaP0

 

Lifters will go at half the rhythm of the crankshaft (4 cycle engine). Here's a bad lifter in a lsx motor to compare: http://www.youtube.com/watch?v=nTDaq1tY7tY

 

sounds like he has a few birds churpn to under the hood of that vette

 

ahh, i hope that's not it. I noticed that my tick is a lot faster and more high pitched than that sound from the corvette. I was always told that rod bearings and main bearings will be a more deep tone compared to a bad lifter sound. Who knows how true that is though
