    Spring coolant top up

    When I lived in Manitoba where it hits -45 once or twice a year, I was driving a Subaru and it needed a maybe 50-100ml top up every year. I always worried my head gaskets were about to go, but they never did. Now I live in the Yukon, and I drive a Yukon, and it hits -50 a handful of times a...

    Confirmed brake bleeding scan tools

    FSM should have a pinout that tell you exactly what every pin is used for. That would be the only place I trust for info like that.

    Confirmed brake bleeding scan tools

    I'm an idiot. I failed to recognize that "functional test" is a command made by the scanner. I thought it was just making sure your bleed worked. Sorry to anyone I have misled.

    Confirmed brake bleeding scan tools

    https://www.motor.com/magazine-summary/nuts-bolts-kelsey-hayes-4wal-june-1998/ Bleeding the BPMV is rather complex on the Kelsey-Hayes 4WAL system. A pressure or vacuum bleeder is preferred over using the brake pedal for this procedure. If the pedal must be used, consider removing the master...

    Confirmed brake bleeding scan tools

    Has anyone messed around with the manual and bleed procedure? On the 4WAL there's a pair of 10mms on the side of the module, and the high pressure valves in the front need to be held down (there's a Kent tool # for holddowns) then you can use the bleeder screws on top of the unit. Seems like...

    1999 L31 Engine with nearly 260k, Timing chain plus what else?

    If you do the timing chain I would count on doing the pan gasket. It always breaks off where it meets the timing cover when that comes off.

    Crank relearn and cam retard offset question

    I'm not 100%, but I think setting the CMP retard is a function of timing, crank sensor, and cam sensor. If none of those things has changed, I would assume its still ok. Dash command is an ok app to have on hand. With a cheap amazon Bluetooth OBD2 you can check CMP retard at home.

    Building a stroker motor

    I like hearing this. The generally accepted limit of the stock spider seemed to be around 400hp. I'm currently working on a 383 with the stock mfpi spider and a very mildly ported stock intake/throttle body. Did you install a larger fuel pump to feed the beast?

    Motor and Transmission Mounts

    I noticed Off Road Design (ORD), and Schumacher Metal Works both made a race style motor mount. Lots of steel, not a lot of rubber/polyurethane. Seems like a race/extreme duty kind of part, but with no good OEM type options available, has anyone tried these?

    U bolt plates

    I have this kit on the shelf right now, waiting for my 14B swap. Seems like a much improved design over the stock dirt holders.

    Apps that read CMP Retard Offset?

    I spent a few days messing around with this, and was never able to make it work. I broke down and purchased dash command and the pod package for my vehicle and it worked right away. I figure my time and suffering is worth 20 bucks.

    Weird question about a bypass filter

    Just change the oil. Bypass makes sense on tractor trailers, when your engine takes 15 gallons. Our trucks... not so much.

    Anyone Tried Cunningham OBS- tie rod sleeves

    Have them. Great product. Nice to support a small business making cool parts for our trucks. Get the door bushings and a rag joint delete while you're at it.

    Apps that read CMP Retard Offset?

    Torque pro has the best layout of any of these apps, by far (but the bar is set awfully low). I have used it for many things, but I was unable to get it to to CMP Retard. There are threads out there with the "recipe" to add it as a new PID, but I spent days struggling to make it work. Finally...

    1991 CHEVY S10 TAHOE 4X4 5.7 VORTEC

    2wd headers tend to be longtubes, 4wd tend to be shorties. Long tubes make more power, shorties don't do as much. Do a search for camshaft, there are a pile of threads with lots of detail. There are a couple of GM cams, a couple of comps, and a couple of lunatti that usually come up...

    Really wish ppl would stop bringing me trucks with hydraulic fluid in trans

    Bob Is The Oil Guy is an entire forum dedicated to armchair engineers arguing about which dinosaur juice is better, and its absolutely insufferable. I second the motion to return to whale oil.

    Oil Filters with good anti-drainback valves?

    Worn valve guides might be,. Worn valve stem seals are often the culprit behind the puff of blue smoke on vehicle startup, and accelerated oil consumption.

    89 RCLB K1500 - Quality time with my son building his first truck.

    I made the same mistake, and it cost me a set of bolts. Truck looks great! Really clean job you're doing.

    Rebuilt Motor Backfiring No Start

    With cylinder #1 at TDC, you need to line up the marks on the distributor housing, and the part that rotates and drop it in. The confusing part is, when it settles in place, the marks will no longer be lined up. To get your cam-crank correlation the ball-park, Same distributor as it had in it...

    Reseal/rebuild NP241C parts???

    I've always had bad luck ordering seals ahead of time. There always seems to be a couple versions of these things in slightly different measurements. Whichever one I order, is the one I don't have.

    Anyone ever change out a crank position sensor?

    There are shims intended to get the air gap set correctly. I believe you're supposed to use a small piece of playdoh on the sensor, torque it down, and remove it to measure the gap. Check the FSM for exact details, I can't recall it offhand.

    Swapping front diff help

    The second bit is a switch. In my truck, when the front dif is actuated the switch is tripped and it completes the circuit to the lightbulb in the 4x4 lever housing. I assume its similar with the electronic transfer case models, but maybe not. 97 was supposedly the year a lot of models started...
