    5" Exhaust Anyone?

    Geez, going from 3 to 4 made my truck a LOT noisier and gave it a nasty drone. Can't imagine what 5 would be like. I'm going back to 3 next chance I get. 4 was tight on my 4x4 but cleared everything OK... it was the Dynomax kit with some adaptations.

    Original Wheel Colors, Bullnose Era

    Interesting answers, guys, thanks. Seems like it may depend on year. I have been digging thru my data books but wheel color is not mentioned directly. Most of the pics in there are B&W and many show light colored wheels. The few in color are all XLTs with the full wheel cover so you can't tell...

    Better oil filter?

    That filter is likely capable of two normal OCIs in an IDI. It's just HUGE! One good long one makes more sense, IMO. I suggest you take an oil sample at the end of your next OCI. That will tell you if your truck is capable of going farther. If you are running a normal OCI with a modern oil and...

    Original Wheel Colors, Bullnose Era

    I finally found some wide steel wheels for my old '86 that will carry my stainless steel hubcaps for that o-so-retro look. Before I paint them, I wanted to consider what the original color was. The earliest pics I have of my XL truck, the wheels were argent and that's what I remember (but it's...

    Better oil filter?

    The Donaldson ELF or Syntec is a great filter but it's expensive and it only makes financial sense if you are going to use all of it's capabilities. The specs I have is that its 98.7% efficient at 15 microns. That is about as good as it gets in the full flow world and I believe Amsoil uses that...

    anybody not using lube in the fuel?

    I generally don't add anything. Don't feel called to do much in that direction either. In 26 years of in the same truck, I had the pump done once... and that was as much tweakage to get the most out of the turbo as anything. From the material I've seen, PROPERLY TREATED AND ADDITIVIZED...

    axle gears contact pattern - take a look and voice an opinion pls

    I have Dana 60 manual right here and it says 0.004-0.009" checked at three point around the gear and they can vary only 0.002" between the three points. If you are within that range you are OK. SIx mionths ago I set up a front D60 in a Dodge at 0.004-0.005" and it was fine. That's tighter than...

    axle gears contact pattern - take a look and voice an opinion pls

    Get the depth right AND the backlash. What you don't do right now, you will regret later and agonize over for a long time even it it does sorta-kinda work down the road. Or work for a while. I have seen a couple of failed front diffs that were haphazardly set up (tight backlash) on the pretext...

    axle gears contact pattern - take a look and voice an opinion pls

    Can't tell very well on the drive side. It's MUCH more difficult to read used gears. Sometimes it's virtually impossible because they get so polished and all you can do is set up via a pinion depth gauge. I can read the coast side a bit better and it looks like the pattern is a little "faced,"...

    Well bleep!!

    Condolences on the string of bad luck. Try to think of it as getting all the crap over and done with in a short period, which often buys you a long run of no-problemo. Hard to imagine the bore wearing that much in just 40K miles. When I tore mine down at 140K and 23 years, the WORST cylinder...

    10W-30 OK over the summer?

    And that is so bizzare. I'm out in Nowheresville, Ohio, and appear to have more oil choices than a dude in Caliprunia. where everything is normally possible.

    10W-30 OK over the summer?

    When you get right down to it, any oil rated CF-4 or above and from straight 30 to 15W40 will be adequate in our engines if climatic conditions are matched to the viscosity and the oil change interval is adjusted to suit. "Optimal" is another discussion but a lot of that would have to match the...

    10W-30 OK over the summer?

    Been running 10W30 Rotella or DELO in mine for decades. The only times it hasn't had 10W30 are in the days when the 10W30 diesel rated oil was unavailable in my area at various times. Straight 30 grade or 10W30 was the earliest recommendation before 15W40 took it's place in about 1986. I would...

    different gear ratios front and rear

    The difference between 3.54 snf 3.40 is tiny and as pointed out, many companies did that exact mismatch. Ford included. You'll be fine! Ford always had a problem matching the 9-inch ratios to Dana Ratios. The design of the 9-inch required different gear cutting machines and in the day, they...

    CDR Explained

    RLDSL: When I read what you quoted above, I was left with his main point being, "If you have oil consumption problems, don't necessarily or arbitrarily replace the CDR as the first step."

    Trans Temp Gauge

    I would like you to define "actual trans temp" and what circuit the test port on an A4OD is plumbed into? There are about four different temp zones in the average automatic transmission. I'm trying to get crystal here.

    CDR Explained

    It's on the front of the head, just above the block deck. It's an Allen head plug and it goes into the rocker area oil return, which goes back into the block. Justin (cdx825) clued me into it's location at the '12 rally (thanks again Justin). I've attached a crappy pic (I have a $2000 camera and...

    Trans Temp Gauge

    "True reading?" What does that mean? What flow is the test port reading? Many people think, and I agree, that the sump temp is the best place to read because that is the oil the pump will pick up to circulate. I agree about return line, though there is something to be said about knowing...

    CDR Explained

    John, Well done! Nice explanation and solid reasoning. I love learning stuff! I will add one thing RE aftermarket turbos... at least some of the old ones from Banks... complicate things a bit. If you look at the pic below you will see how Banks relocated the CDR (3) onto the airbox upside...

    Trans Temp Gauge

    ^ This. As I said earlier, I THINK that port shows cooler outflow, which comes from the converter and it's the hottest oil in the trans and having monitored that aspect on four truck over 25 years, I can say that 250 isn't out of line. If that port isn't converter oil, then nevermind but I'd...

    Trans Temp Gauge

    I've had temp senders in three places on older trucks and could read the temp of the pan, the cooler out (the hot time out to the trans cooler) and the cooler in(from the trans cooler to the trans) line. I had one gauge mounted but a three way rotating switch. When the pan was 140, the cooler...

    Trans Temp Gauge

    Another possibility: I believe that port reads the converter oil temp, which is always the hottest oil in the trans because it's often slipping.. until the converter clutch locks in, which it does only intermittently in town. Try going out on the highway and let the converter lock up for a long...

    I'm with Icanfixitall. You always regret MOST the things you don't do. When I want to gamble, I go to Vegas. My time is actually worth something, to me and others, so not fully checking out something that is already have 2/3s apart. Especially when it has some bad mojo showing seems...
