I run the SS M90 kit. That's why the belt is like that. Which video did you watch? I fixed the no start/cranking problem.Quote:

Scanned for DTC's. There isn't one. It sounds good when you rev it at idle, but when driving it, it's sluggish, knocks and ticks. I think I disabled P0300 a while back though. I will re-enable it and see if it throws a multiple misfire code.Quote:

I watched your vids of the engine, and in one of the videos I noticed this:
164d655b.mp4 video by Bedwards923 - Photobucket
At 45 sec., it looks as though there is a bolt missing.
almost sounds like the rotors hitting. Pull off the blower belt and make sure it spins free
edit: well now that I listen again maybe not lol.
your WOT run video theres a nasty misfire. ALso sounds like a dead mis on the other video
I ran it with no belt. Same noise.Quote:

I could hear it while I test drove it. Not sure if RPM affects it or not. I'm honestly just going to to get my mechanic to look at it. I don't have time for working on this anymore.Quote:

I wonder if I have bent valves or something... Since my compression on the cylinders 1 and 3 were so low. It runs like complete ****, misfires and everything.
Have you checked the compression since it's been running?
Not yet.
On my way to test the compression.
Didn't have time to do a compression test. For anybody who uses HP Tuners, I did a cylinder balance test. I'm very confused by the results. Normally the RPM of all the cylinders are around 90%, give or take 5%.
I think this issue may be a bent or a set of bent valves. Can someone help me interpret this scan?
#1 - RPM = 720 - 91%
TPS = 0.1 - 65%
#2 - RPM = 927 - 117%
TPS = 0.0 - 49%
#3 - RPM = 764 - 96%
TPS = 0.1 - 65%
#4 - RPM = 943 - 119%
TPS = 0.0 - 16%
#5 - RPM = 748 - 94%
TPS = 0.0 - 33%
#6 - RPM = 843 - 106%
TPS = 0.1 - 50%
When the harmonic balancer was put on wrong (basically 180 degrees off), everyone was saying that it would throw off the timing. So then is it possible for a piston to hit a valve? I'm confused, because my cam and crank sprocket were still timed properly, connected by the timing chain. I don't see how it would throw off the timing.
the timing we were referencing is part of the ignition system, so when the spark plugs light up. the timing on the timing chain is different and that is static. if the timing on the timing chain was right then the pistons do not have a chance to hit the valves.
That sounds like either a rocker/lifter noise or an exhaust leak. Your vids kinda make it sounds like an exhaust leak near the EGR area. And yet, I'd be pulling the valve covers and looking at any w/o oil on them. Any dry ones may have a collapsed lifter or something odd wrong there.
Should I try an oil additive (Sea Foam or something)?
Here's what I'd do.
