    Gauge questions

    I've read a lot of threads on gauges and I am trying to narrow down a way to go about troubleshooting. My oil pressure gauge reads 45 psi. My voltage gauge (engine running) is 17v. My temp gauge (engine warmed up) reads 145*. My gas tank gauge reads at about 2 o'clock. I know that there are no...

    I learn something every day, but not today....

    I'm getting all the indications of the EGR valve sticking, so I decided to just order a new one. This is where the fun started. I have an '85 GMC K2500 with a 350. I've been under the impression that it's a VIN L engine according to everything I've researched. When trying to order a new valve I...

    Flange bolt question

    I recently pulled out the crappy dual exhaust someone had previously put in, and I'm planning on going back to the Y pipe and single exhaust piping that the truck came with originally. While pulling the duals I discovered that the passenger side and driver side flange bolts were different...

    Emissions issue

    Someone in the past has messed with the smog system. The smog pump is gone. Upon inspection of all the lines, I've come to the conclusion it's messed up. I'm posting a picture of original next to what I have. Any line with an X on it isn't there. I've drawn in lines to show current routing. A...

    Should I?

    I saw a '85 3/4 ton 4wd today that has damage to the passenger side door (nothing severe). It has a 350 c.i. and comes with a bed cover. Don't know the mileage but the owner is asking $2500. I'm thinking about offering him $2000 cash. Should I?

    Hardest valve cover in the world to find

    It's valve cover for a 250 CI inline 6. It has 5 bolt holes on the distributor side and 6 bolt holes on the carburetor side. I can find gaskets all day long but I've spent hours trying to find the cover. Any one know of a website I could check out?

    Valve adjustment question

    I've seen two different ways to adjust hydraulic valves like the ones in my 250 I6. One was to set the Harmonic Balancer at TDC and adjust certain valves, then move the HB 180* and adjust the rest. The other way was to mark the HB at six equal positions starting at TDC and adjust each cylinder's...

    A clutch pedal adjustment question

    For years I've put up with the clutch pedal going almost all the way to the floor to shift gears so I thought I'd try to make an adjustment. I got underneath and pulled the adjustment piece and noticed what looked like a worn spot. I'm attaching a picture. Is this worn or was it originally like...

    An oil gauge question

    Recently I restored the gauge cluster. Before doing it the oil pressure gauge would vary from 45 psi (cold) down to 30 psi (hot). I noticed today that it has dropped to 25 psi (cold) and 15 psi (hot). I don't remember if the gauge was on zero when I put it back in. I checked the oil level which...

    My engine used to sound beefier

    Hi all, I haven't been on the forum for a couple of years as I purchased a 2001 Jeep Grand Cherokee and it's taken all my time and money. It's done so now it's the square body's turn. I pulled the muffler today and clamped in a new one. The engine has quieted down a "little" bit. Next up is...

    Cold Starting Issue

    I've been pretty busy at work and didn't have time to post this question earlier. When I go to start the truck (IL6 250c.i. 1 Barrel Rochester carb) I depress the pedal a couple of times and start the engine. It idles very rough and if I don't hold the pedal down for a couple of minutes it...

    High Voltage?

    My voltage gauge has always read a little high but lately it seems like it's a little higher. Here's a picture. Is this normal ? If not what would cause it to be so high? Our temps lately have been as low as -2* and this morning the battery was dead.

    My stereo install

    I recently installed a pair of BOSS 4 x 10 speakers in the cab corners. I have purchased a BOSS 800w amp direct from the BOSS website. I have a pair of Pioneer 6 x 9 speakers which were installed when I had the original system installed a few years back. I've removed them from their original...

    MC leak. Rebuild or replace?

    I was looking at my stereo wiring today in preparation for an amp installation when I saw this at the firewall.I'm including a picture of the engine side also. Are all rebuild kits the same or is there one in particular I should be looking for?

    I have no idea.....

    While removing the screws that hold the front bed panel, I found a 3 prong electrical connector on the driver side between the cab and the bed. It comes off a larger wiring harness under the truck and is held by a screw thru what looks like a ground wire. It's located right below the top of the...

    Front Bed Panel Removal

    I have removed all the screws holding the panel. The 2 above the gas tank took a while. My question is: should the panel now come right out, or do I have to loosen up the side panels too? I've tried moving it but it doesn't seem to want to move. It does wiggle a little. I must be missing...

    Vent window filler

    I can't seem to find new filler rubber for the glass in both my vent windows. I can find the weatherstrip kits for the frame/divider bar, but not the glass itself. It's #3 in this picture. Any ideas?

    Lens restoration

    Got a new (to me) company truck to use in my new job position. It has extremely yellowed lenses. I bought a 3M kit, on their dime, and started this evening. One down, one to go. Once I get done I'm going to do my Blazer.
