Please help! Terrible engine knock at 30k - Camaro5 Chevy Camaro Forum / Camaro ZL1, SS and V6 Forums

R3VOLT · 09-04-2016, 05:16 PM

Sorry this thread is so long but I was going to spend this Labor day weekend installing upgrades until this happened!

It sounds terrible and the dealer wants $130 for the "Initial inspection" but may/will cost a lot more if they have to do a 6-8 hour tear down of the motor to diagnose. Plus the cost of towing.

https://youtu.be/zFiWzmsIjCE Here is a short video with the awful sound!!

I just finally got all my mods that I ordered all of which I did a ton of research including a ton on this website. Thanks for every ones posts and threads! I only installed the Cold Air Inductions air intake 2 weeks ago so far. I have sitting in my garage right now my V max Black Ice-olater, planning on porting both TB and Intake Man, OBX-R LT Headers fiberglass wrapped w/ new OEM metal gaskets and bolts. They came with the cat delete HF resonators and O2 senor extensions, Pypes 2.5" cat-back w/ M-80 race pro mufflers and 4" Tips, Team RX CC, Vitesse TC, IAT relocate and Trifecta Tune. I also have been doing a ton of Body additions but those are rendered irrelevant as of this moment.

I bought the car with 14.5k on it and had to replace the clutch at 19k. This is my 7th Camaro owned 1 of every Gen except 6 and I have been driving manual trans for over 20 years so the previous owner had to have fkd this one up. I have rebuilt motors back in the day on my 78 Z28 350 but things have changed. The last oil change I was extremely busy moving and had an oil change place do it. They supposedly used synthetic but I really cant be sure. I will never leave my car in the hands of incompetent individuals again. That was about 3000 miles ago and I doubt they used the Dextos approved kind they should have. My biggest question is that if it is a bearing do the make an upgrade kit since I have read that my Camaro has a build date of 3/2010 and they had problems with them prior to 9/2010 builds. Is this repairable or do I need to just buy a rebuild motor and swap? I just blew all my $$ on the mods by the way

30K is a bit past redline.

The oil was a little low but not completely dry. The oil is thick and brown with no unique smell or metal flakes. Like I said I doubt they used dextos approved or even changed the filter but still as long as there was oil it should not have had that much of an impact. Not a single code or any warning lights just the terrible sound/s. I am really struggling with just ripping the motor apart but don't want to waste my time if it is not able to be repaired. I think a timing chain is ruled out leaving just a spun bearing/thrown rod

. I have been trying to find a replacement bearing kit to no avail. If I'm going in I'm doing all of them along with any other upgrades while in there. Just don't want to waste the time if I don't need to but if that's what I have to do then so be it!

Could be bearing knock. You're out of warranty so don't have a dealer touch it ... and don't drive it. Tow it to an engine builder and have them look at it. If you had to replace clutch at 19k then prev owner probably beat the shit out of the car and didn't maintain it.

This sounds like piston slap. Notice how it changes as the revs go up and down. Could also be a wrist pin problem.

I second that opinion clutch at 19k is not normal
