    Vortec 454 Heater Core Bypass

    Good advice! I was trying to figure out a way to guarantee the leak was the heater valve-I forgot they had those. I guess if I'm going to mess with this, I might as well fix it right.

    Mine has a broken clip, so it takes me about 30 seconds. :D

    Vortec 454 Heater Core Bypass

    It was a mistake. I put it in one place, realized I put it in the wrong spot, and made the other one with intent to delete the first one. Then I forgot only mods can delete threads.

    Vortec 454 Heater Core Bypass

    Thanks, that's exactly what I needed to know. It likely won't be permanent, so I'll go the barbed fitting route. I'm going to go out today and pull all the old lines out to see if the leak is a hose or the heater valve. I DO have rear heat. At least...i did.

    Vortec 454 Heater Core Bypass

    That helps a significant amount. It doesn't seem difficult other than knowing the size coming out of the intake and into the radiator.

    Vortec 454 Heater Core Bypass

    Hey y'all! I bought a 454 suburban about a month ago, and today I was on my way to buy some seats from a guy when I noticed my water temp was high. I coaxed it home, and found that it is leaking from somewhere in the area of the heater lines. What a rats nest of hoses! This vehicle is just...

    What Exhaust For A 98 5.7, Basically Stock??

    If I remember correctly, those trucks have 2 cats, and stock is a 2 in to 1 muffler. And it wasn't too loud in the cab. You could carry a conversation comfortably. The only minor drone was around 2500 rpm, and was in think more from the intake, not exhaust.

    Cleaning cylinder heads while on engine

    Yeah, I think if it is still running mostly smooth at 274K miles with the crud, then that crud may be what is making it run smooth at this point. Thank you.

    What Exhaust For A 98 5.7, Basically Stock??

    I had a flowmaster 50 series dual in dual out on my 98 350. It also had a K&N CAI on it, and it was the perfect sound for me. Here is one with a close setup. With the K&N mine had a little deeper WWHHHHOOOOMMMM sound in the cab as well. Besides, that is the sound perspective we care about...

    Cleaning cylinder heads while on engine

    Thanks for the advice! I hadn't thought about the baffle in the valve cover being what I was feeling, I just assumed that it was a rocker i was feeling. And I got to thinking about the ATF thing last night after I posted and did some more reading, and I think that is the route I will go. I will...

    Cleaning cylinder heads while on engine

    Hi everyone, I have discovered on my truck that the PCV valve has been sitting on top of the valve cover loosely, only held in place by hard vacuum line. I stick a finger down inside, and could feel dust and hay and all sorts of crud sitting underneath. I know I will at least need to pull...

    Low operating temp?

    Scuby, clutch was tested first thing in the morning before it was started. And thanks for the advice on adding an extra ground. I'm thinking about doing the big three electrical upgrade anyway, so this is a good time to do it.

    Not-so-new 94 K2500 farm rescue

    Update on EGR testing- the valve itself moves freely, and almost feels like it has absolutely no diaphragm left. When the truck is up to operating temp, moving the valve by hand has no effect at all on the idle. I know that is a sign of clogged ports, so I am pretty sure I will be pulling the...

    Low operating temp?

    All sensors and ground are within spec. Something else I found today as I was troubleshooting an EGR code- the truck warmed up to 160-170 after I just started it and let it warm up without moving. The minute I moved, it went back down to what I described above, and then warmed up again after...

    Abnormal amount of condensation on startup?

    I haven't noticed any cross-contamination in the oil, and the guys that did the oil change didn't say anything about milky oil today. I'll do the coolant cap thing tomorrow. And if it is the drain hole on the muffler....new exhaust from the manifold back goes on Thursday. So if it is still an...

    Low operating temp?

    I hope that the parts I bought were not bad out of the box. Both were replaced about 2k miles ago, and although the temp switch fixed the startup issue with the engine flooding, the temp sender in the block made no difference whatsoever. I'll look around and see if I can find those resistances...

    Temperature today was mid to upper 30's.

    Abnormal amount of condensation on startup?

    Hi everyone, Trying to get my 94 K2500 350 in good operating condition. Upon startup, there is a tremendous amount of condensation blowing out of the exhaust. I have never seem a vehicle blow this much out. It doesn't seem to lose any coolant, and I never get a coolant smell. I am...

    Low operating temp?

    Hi everyone, I am trying to get my 94 K2500 350 back in to good running shape. It has always had this issue that I can remember since my grandfather owned it, but the operating temperature is VERY low. After a 1.5 hour drive, according to the gauge, the temperature of the truck hovers...

    I'll trade you! I miss my '98. I'm a stock-ish fan, so I wouldn't touch much on it! That is SWEET.

    Not-so-new 94 K2500 farm rescue

    Made a little progress on refurbishing Big Red today. I had the engine and both differential oils changed. My duplex will not let me do anything involving vehicle fluids, and I don't have anyone with a garage I can borrow within an hour and a half drive, or I would have done it myself. I asked...

    Not-so-new 94 K2500 farm rescue

    Hi Kenny, the Impala trans went out Dec. 2012. And I have been digging under the hood, and found that all of the remaining slop is from the ISS. So you say that an 88-94 Cherokee ISS will fit? Door hinge bushings are also on the list once I enlist a buddy to give me a hand. The driver door was...

    Hi all, This is my first post on the site. To be honest, I do not know when I registered, but apparently I did because my email address is already in the system. Anyway, I am a lifetime chevy driver, minus my six month foray into chrysler products where I learned that they are not worth...
