    First AC problem of this year.

    I have the dreaded 3 light flash then nothing. Pump clutch does not engage. I tried jumping the low pressure switch on the dryer. Nothing. Tried unhooking the battery for a while. Nothing. Swapped relay. Nothing. All fuses good. It has no codes for HVAC. When commanded on with scanner, light...

    5V reference. What's ok?

    I'm working on a 94 TBI engine 5.7 gm. It will start then die and i can't figure it out. The only thing i can find possibly wrong is the 5V reference to the sensors. Supposed to be 5V but i measure 5.22V Things very a little so 5V can't be a hard number but i have spent a couple of hours...

    Anyone feel like helping me tune the trans with HPT

    Here is what i think is a decent log. Change it to Log2.hpl as we can not upload .hpl files. Would like to get a little firmer and faster shifts. I don't know how to do that my self.

    ZDDP and cats.

    Stumbled on this last night and i found it interesting enough to do some research. Seems it is fine to use if the engine is not using oil. What do you think?

    Few things I wonder about.

    What makes rear main seals go bad? Could it be the PVC system becoming partly plugged causing the crankcase pressure to rise slightly? If you're rear main is leaking do you have the old or new style valve cover? Most high mile 6.2s all seam to have low hot idle oil pressure and bad cam...

    06, 5.3, Was running bad

    Was over at a guys house today because his truck was running VERY bad!!!! He had changed the fuel pump and throttle body with new. He was trying to use a cheap scanner that would not read any codes and would not clear any either. Hooked my scanner to it and i could not get any codes. I assume he...

    VVT cam gear question.

Reason im asking is Jeggs shows this set to fit everything but Summit says it does not. Melling 3-3SRH60HVVT Engine...

    Door pull breaking

    My DR door pull is starting to act funky and some part of the system is going bad. When looking for a cable i see like 3 different length ones. How do you know what one to get without taking the door apart?

    Rear heat

    Im pretty sure the rear blower motor resistor might be the problem but i'll ask anyway. The rear blower motor blows very little air out the vents. Is there any setting i don't know about that adjusts the speed of the motor?

    6.2L Winter Refresh

    So im going to refresh this 6.2 and it all starts with collecting parts to do a garage refresh. Keeping a cheap ish budget in mind, using name brand parts with no machine work and keeping everything std size. This weekend i need to figure out how to get this dirty block clean enough to even mess...

    Bored, so I took apart my old 6.2

    So ya, Nothing going on today so it was a perfect time to do this. Here is my old engine. Removed at close to 240K Ran great but did have a piston slapping when cold. Both valve covers are all gunked up. The valley cover has probably never been off. The silicone gaskets were all hard and...

    Blew another strut.

    Well i have blown another front strut today. Driver's side this time and the 3rd strut due to off-roading. It's locked almost fully extended. No suspension code this time though. I do not think the Z55 struts are designed for anything other than pavement. I must be working them too hard but i...

    Transfer case tag.

    Wondering if there is any way at all to tell if this is a 27 or 32 spline input from the tag. I don't want to pull it and find 27 splines. Bad pic but it is what i took. Looked better on the phone.

    Upper control arms rubbing.

    When changing the oil this weekend, I discovered that both my tires are rubbing the Rough Country upper control arms. No to bad and only about the last 1/4 turn from lock. I don't know what that black schmoo is. Feels kinda greasy. Checking the tires and they appear undamaged but had rub marks...

    Finally swapping my engine!

    Started the engine swap on Cracker today finally. Pics don't show all the progress i made today. The intake is off it now. Intake gaskets look like they were sealing good. All wiring is out of the way and fans are removed. Nothing special.

    2008 Yukon dying.

    My friend's Yukon has developed a problem and i can not quite pinpoint the problem. I'm almost thinking FP regulator or bad intake gaskets. It will randomly die like it's out of gas. Restart it and it runs ok (ish) slightly rough. Sometimes runs perfect, hot. When cold it will remote start and...

    Engine noise.

    My engine has a noise and i can't decide what it is. It is not a rod or crank knock. It is not in the bottom end. It is only 1 cylinder and only when cold. It goes away when the engine temp reaches 190ish on the temp gauge. Engine runs fine otherwise. Idling cold you can't hear anything. You...

    Transmission year swap.

    @NickTransmissions I might buy a 2011 Yukon Denali XL 300k, 6.2/6l80E that has a cylinder 7 misfire and a rebuilt 6l80E with about 4K since rebuild and has receipts. I'm thinking of offering 2K as they are asking 3K and been sitting a couple of weeks now. The trans alone is worth 2K if it will...

    Shock length. Spacer or not?

    So if anyone was watching my RC 4in lift fail, I have a question for anyone really. I ended up putting a 2in lower spacer on the front struts. I found it was a little low looking in the rear. So i made the rods longer using the auto level air shocks, making the rear sit just a hair higher than...

    Front strut part numbers differences?.

    Does anyone know what the difference is between these two front strut part numbers? 19420492 19420493 They are both listed to fit a 2007 Yukon XL at RA. I do not think a 2007 Yukon XL Denali had Z95 as an option and only had Z55?
