    TBSS intake manifold install issues

    Simply because it has an inlet and return appropriately sized for the factory fuel line connections, and an outlet appropriately sized for the fuel rail. It makes the fuel system plug and play. You could absolutely do some additional work to put a regulator or a return style filter down on the...

    TBSS intake manifold install issues

    I used the corvette return style fuel filter on mine. The tab that supports the fuel rail inlet to the fuel rail must be cut and the fuel inlet be bent up slightly, and the fitment to the firewall is very tight. Tighter than I would like. If I were to have the intake out again I would bash the...

    1997 7.4l - At my wits end with an irregular miss.

    All right yall, I need some help. 97 Suburban 7.4l 4l80e 4wd 185k miles. Irregular miss starts at 3k rpm and gets worse with engine speed. Load is not necessary - it will do it in neutral. No codes. Previous owner (buddy of mine) did injectors, fuel pressure regulator, plugs, wires, throttle...

    1997 Suburban 454 ECM Swap Help

    Agreed. The plan will be to get it running again and then do as much as possible to check for other issues throughout the system. There have been a lot of cooks in this kitchen, which I knew going in, so I've got a fair amount of work ahead of me to bring it back to solid and reliable.

    K2500 Brake Upgrade?

    Hi all! Long time owner of a plurality of GMT800s, first time owner of a GMT400. I bought a 98 Suburban K2500 7.4l Automatic off a buddy to haul the family and pull the camper with. The one place I'd like to upgrade is the brakes. My question is this - does anyone know of an easy brake upgrade...

    Lifted Tahoe project/daily driver

    Agreed - wheel spacers can be dangerous if misused. Absolute largest I'll use are 2", absolutely must be hub centric, and high quality studs in the spacers. Some spacers use a lower grade stud than factory. Actually use a torque wrench instead of an impact with spacers as well, and double check...

    Rock Sliders

    I'm planning to cut our my rusty rockers and weld back in 2x5 box tube and tie back into the frame.

    A/C Box blend doors

    Looks like a pretty simple part - I'd say avoid the scanner and manually model it. It will be more accurate with a higher likelihood of fitting.

    A/C Box blend doors

    Haven't personally. I'd avoid PLA because of the heat, but ABS or Nylon... something like that I'd say it would hold up just fine.

    AC Leak - Pulling my hair out.

    Quick Q, somewhat related - how many blend doors are there? I've got the number three in my mind but cannot remember if that's correct. I've got an actuator that's been finnicky the last couple years, so I'm going to replace those while I'm in there as well. And finally put in that crack-free...

    Saved from scrap

    And pay the premium for injectors from the parts store. There are fake "AC Delco" injectors floating around. I had one stick open and kill a motor.

    Saved from scrap

    I'd check spark plugs first - I've changed many a factory set at 250-280k miles and it makes a world of difference. My next guess is fuel injectors. I've had 2 or 3 with misses like that I had trouble tracking down and it was clogged fuel injectors. I'd swap coils around cylinder to cylinder...

    AC Leak - Pulling my hair out.

    Having trouble finding my UV light now. Lets assume the answer to that is yes (will confirm once I find the light). What would that point to - evaporator?

    AC Leak - Pulling my hair out.

    Hey all! Need some help from someone more experienced with AC work. I have a refrigerant leak that I cannot find. It leaks out every 12-24 hours, so I've been living without air for the most part. I've put UV dye in; couldn't find anything. Put a double shot of dye in; couldn't find anything...

    Any benefit to running anything above regular (87 octane) in 4.8L V8?...

    I've run both across many vehicles. In a standard gmt800 I have never seen a difference in economy or power. Same was true for the one gmt900 I owned. I run premium (93 octane at the elevation I live at) in my current daily, but it's a 6.0 with 5.3 heads so it needs the extra octane due to the...

    I want to convert the conventional steering to rack and pinion on an 01 GMC Yukon. Help please!

    The short answer is you can do anything with enough time and money. There are no bolt in options, but an experienced automotive fabricator could certainly complete the conversion.

    03 Yukon SLT 5.3 - 4L60E is fried - Best way to sell/dispose??

    Lots of folks would go for private sale if it's otherwise clean. Still won't get a lot for it, but someone would be willing to buy it and bring a trailer.

    Rear axle cross compatibility.

    Had one out of a gmt900 sitting in the yard for a bit. All the mounts and brakes looked the same. Bought it without a yoke, guy said he had to change the yoke cause it was different. RockAuto lists them as the same universal joint so I'm not sure on that. 3.73 more common in Z71 but available...
