Ordered this today. Had one of his earlier versions for 10+ years and it took a dump last week. I like you get all the extras built in at half the price of major brands. Car has 210K miles so didn’t want to spend a ton.

Ive always thought those were neat. I like the oem look with the aftermarket options. Buddy had a Rosen in his truck for a while but didnt seem to last that long

Well I seem to have this weird noise coming from the front left. Could be the wheel bearing or the diff. Like a humming rubbing sound. Too cold to get under it and snow everywhere. It’s faint but I hear it.

I’ve been collecting lsa parts as well. That’s going to be a fun project coming. Btw it’s not going on my Tahoe.

WTF?? How was it running before? @mikeyss bent a rod in his too, but much more severe then you have. He was a GM tech so maybe he can make some suggestions.

My rod only bent because part of the valve seat dropped and met the piston. Parts of the piston then got chewed up and the rod didn't like that too much. I'm just thankful it happened with the rpm's under 1500, the damage would've been much worse.

I was able to carve out a few hours this morning with a buddy to replace my broken driver side motor mount. The old one was almost completely ripped in half. I'd prepped by watching a bunch of videos on it, and picked what I thought was the easiest method. We went in from above, removing the steering shaft and exhaust manifold heat shield. We had to rip apart the mount heat shield to make room. My buddy is 4 inches taller than me, and has longer arms. So he reached the rear two mount-to-block bolts. If I were to do it solo, I'd have put it on jack stands and removed the front wheel to access those bolts. Overall it wasn't terrible. Total time was under 2 hours.

The truck is much better now. No more clunk when taking off. And if the H3 mount transmits more NVH than the stock Denali one, I sure can't tell. We saved the other side for another day, as weather is moving in, and we had family coming to see my dying MIL.

I found my exhaust leak, too. The rear most driver side manifold bolt is broken off. It HAD to be that one, of course. Thankfully my buddy does lots of car repair and is a much better welder than I am. We've made a plan to fix it when we have more time.

New H3 mount vs. old torn one:

Close-up of torn one. Thanks GM.

Lastly I got to break in my new cordless ratchet. It's a cheap knockoff of a Milwaukee. But it got good reviews. It worked like a champ, saving a bunch of time spent hunched over the radiator support.

Got a link for the tool?

Just got off the phone with Stainless Works headers. They have headers 1 3/4 going into 2 1/2 collectors . And SW won't make the 1 7/8 into 3" collectors that I will need for a supercharger application. I like the 3"dual exhaust they make for they're headers. But this 1 3/4 into 2" collector is NG for me. CRAP

Here we go again.. everything is a hassle.
