    A/C Drier and lines frosted over

    Something new i found out today. The compressor runs the entire time the ac is on. But even if I turn off the ac, but keep the blower running, the compressor still runs. Again it never gets warm inside but the lines and drier freezes up. But once the compressor is off, within a minute the frost...

    A/C Drier and lines frosted over

    45psi while hot after taking it around the neighborhood for about 10 minutes. And no issues, just curious why I’m seeing frost on the lines but the ac still works. Maybe it’s worth mentioning that I’m in Florida and we have both front and rear ac going on mid to full blast.

    A/C Drier and lines frosted over

    I tried doing a search and found this thread, but didn't feel it exactly was on what I needed. https://www.tahoeyukonforum.com/threads/a-c-accumulator.105734/#post-1260829 Anyhow, I recently connected the A/C high pressure line back up. I did a motor swap and broke the high pressure connector...

    Hole in cylinder 1 piston

    Can you send that to me in a pm? I flushed it with four gallons of distilled water and it came out orange on the plastic bin I drained it into. Then I filled it with dexcool yesterday. But I don’t mind flushing it again properly so I don’t risk anything gelling up. Thanks.

    Just an update, the motor swap went well, and now the truck runs great. Thank you again for all of your help, much appreciated.

    Hole in cylinder 1 piston

    So we're about ready to swap in the new motor, i have some parts coming in friday to finish it up before installing. Is there anything special i need to do when filling it with dexcool? I thought about getting a pressure test kit to make sure that the cooling system isn't leaking anywhere before...

    Hole in cylinder 1 piston

    So I bought another motor that's in great shape. it has about 170k miles, and the head gaskets were done about a year ago since the heads were removed for inspection. The valves were lapped and everything put back together. Question I have that I just thought about, the motor is an '03, but non...

    Hole in cylinder 1 piston

    The lifter for that valve was in two pieces when i pulled the head, and the pushrod was bent. I'm guessing the lifter was the culprit since the last owner heard ticking but never investigated .

    Hole in cylinder 1 piston

    I plan to put another motor in. This will be a daily driver which is why I'm looking for another motor. But we plan to rebuild the original and stash it away for a backup in case the "new" motor takes a dump. We like yukons so we plan to keep this truck as long as possible. I like your advice...

    Hole in cylinder 1 piston

    if it helps, now that the passenger head is off, the rotating assembly rotates pretty smooth now. i think i'll put another motor in for now and rebuild the original, shrink wrap it and keep as a backup. I plan to keep the yukon for a long time.

    Hole in cylinder 1 piston

    What do you mean the rest was his fault? And i have decent heads. They just need machine work. Since my motor had #1 piston with a hole from the intake valve bottom breaking off, what's the chances of the crank being fine? I don't mind doing new rings on all 8 pistons and replacing that one...

    Hole in cylinder 1 piston

    I found another 5.3 with decent miles for 200 for a complete long block. The guy is getting rid of it since he swapped in another motor since this one was sludged up. I planned on replacing timing gear, gaskets all around, lifters and oil pump (maybe). Would I be safe steam cleaning the crud out...

    Hole in cylinder 1 piston

    the heads are 317. everything else on that motor is stock 5.3 like mine. so other than the lower compression, the truck will run normal? I'm not interested in compensating for lost compression unless i need to. Thanks

    Hole in cylinder 1 piston

    I found a motor with the 6.0 heads on it. I know that without them being milled, i'll lose compression from what I've read. Since this will be an everyday truck, and it comes with the intake and heads, both 6.0, other than compression loss, will the motor suffer using stock 6.0 heads and intake...

    Hole in cylinder 1 piston

    Wow thanks, I'll start looking for another motor then

    Hole in cylinder 1 piston

    It has 225K. The plan is to get it road worthy and get another motor from the junkyard that the boy and i will tear down and rebuild as a project. Would it last a year at least if the piston was replaced?

    Hole in cylinder 1 piston

    I bought an 02 yukon xl in pretty decent shape except the engine. The owner said that he heard clunking in the drivetrain, and it chugged to a stop. His mechanic tore basically the whole front end of the engine off, everything but where the issue was and just told him, he'd need a new engine. So...
