    Solved--Rough ride after 2/4 Belltech kit, please Help!

    I just got my hands on an 09’ Yukon and I’m glad I found this post! I’m going to be dropping it in the future cause I can’t stand the huge wheel gap and cause lower is better lol. Anyhow I’m looking at the Belltech kits and wondering what ones to get. If you get the springs only kit can you just...

    Boggy WOT

    Evening all. I’m having an issue with hesitation when my Yukons throttle is floored. Starts out fine for a split second and then no power for a second and then takes off fine. Also seems like there is generally less power on the way up as well. Normal driving seems fine but as soon as you put...

    TBSS swap

    Evening all, I acquired a gen 4 intake manifold and was wondering what throttle body would be the best to go with it? Trying to search for part numbers online and it seems as though throttle bodies from 09’ and up are different than 07-08? Any truth to this? Probably a dumb question but what are...

    No brakes.

    Yeah. Checked all 4 corners. Fluid level was good as well. The brake pedal is not like a limp noodle…still a tiny bit of pressure on the way down.

    No brakes.

    Afternoon all, I have an 03 Yukon Denali (Hydroboost) and last night I had to hit the brakes hard. When I got home the brake pedal went to the floor accompanied by the service brake system and service stability system messages. No fluid leaking. Any ideas where to start?

    Transmission upgrade?

    Wow this is great info! Thanks so much!

    Transmission upgrade?

    Yeah. I don’t have any problems rebuilding the one I have. Just wondering if there was something better to use. I just want mild performance and i never tow anything anyhow. Will definitely put all the “must haves” in when I do it!

    Transmission upgrade?

    Afternoon all. I have an 03’ Yukon Denali (AWD) and has the 4L65e. It needs a rebuild, but my question is there any other transmissions that will work with minimal to no modifications? Would like to get a better converter as well.

    HP Tuners

    Afternoon everyone. Just finished my rebuild and will be starting for the first time right away soon here and I have a friend who has the HP tuners software and what not. Because I put a trucknorris cam and .650 springs I will need it tuned. I’m an absolute dummy when it comes to this stuff and...

    Converter

    Yeah it’s my Yukon so there’s a bit of weight and AWD. You’ll have to forgive me but transmissions and stalls and what not are something I know nothing about.

    Converter

    Currently rebuilding my LQ4 and have a converter question. I’m putting the BTR truck Norris cam in it and from what I gathered I can use the stock converter? I was thinking of upgrading the converter anyway so what would you all recommend? It’s not going to be towing anything. Just a daily...

    Camshaft journal size

    No worries! If you Google LS bearing clearance you get a lot of different numbers. Trying not to pull the hair out…lol

    Camshaft journal size

    On a side note/question…you happen to know what the GM specs for main and rod bearing clearance? I got them all measured out and I’m ready to order bearings. I have .0015 on the mains and .0020 on the rods

    Yeah I guess that makes sense

    Camshaft journal size

    Do you have any ideas as to why they made the OD of the bore different in position 1/5? The journals of the cam are always the same are they not? Why the need to make the bearing thicker or thinner depending on the location? Seems silly to me but I’m by no means an expert on the situation.

    Camshaft journal size

    Thanks!! Yeah I have the first design. The oiling holes are the smaller holes. The 2nd design have larger ones. Just getting ready to knock the old ones out and clean those journals. The rest of the block is ready for assembly. Just have to chase the head bolt threads.

    Camshaft journal size

    Does anyone know when the split between 2003 and 2004 blocks happened? I understand that the journal sizes are different between the two years? My LQ4 is a 2003 with a casting of G13 on the front passenger side. Do these digits correlate to anything? In a nutshell I’m asking which cam bearings...

    Bearing clearance.

    I wanted to do a rebuild due to the high mileage. It started a top end tick and using a little oil. Putting a BTR trucknorris cam, springs, lifters, trays, pushrods. So I figured I’d do it all.

    Bearing clearance.

    Ok. Yeah I’ll try and track some down and check them. Thanks
  21. Denalibro76

    Bearing clearance.

    Yes. Everything was kept in ziplock bags in order. I guess I’m not sure why I need bearings. No issues with oil pressure or anything like that before I took it apart. Zero signs of abnormal wear on the bearings and crank

    Bearing clearance.

    Hey everyone. My apologies if this is a stupid question but I’m rebuilding my LQ4 and I’m at a roadblock concerning the main and rod bearings. I’m not building a high HP/RPM motor, just rebuilding. Can I just use stock OE replacement bearings? The old bearings looked great and the crank looks...

    Pistons

    Ok thanks! Yeah the Odometer is at 260k. So I decided to do a rebuild.

    Pistons

    Hey everyone, I’m getting my LQ4 torn apart and had a question about the pistons. Is there any markings from factory? I’m posting a picture of them and I’m wondering if someone has been into the engine before I owned it. Not sure if they are factory or not?

    Timing chain set

    Yeah. I’m taking the necessary items to the machine shop to get the journals measured and all that stuff. So I’ll definitely be getting all the info I need.
