I would hate to try to diagnose this sort of problem without my laptop and scanner software. I pull up the sensor view and monitor the pertinent sensors. I was able to quickly diagnose an intermittent wastegate solenoid on my truck by watching IAT, boost, solenoid duty cycle while driving...

I know this is an old thread, but I had to chime in on the Peninsular take-offs. I bought one of them when I rebuilt my engine. I had overheating issues from day 1. I ordered the Heath clutch and plastic fan, which made some difference, but still the thing got hot climbing any hill empty...

I realize this thread is old, but plenty of folks (like me) end up here on search. I purchased a Peninsular takeoff pump when I put my engine back together. It failed after fewer than 6000 miles. ...leaking out the weep hole. Of course, it's taken me 2 years to put that many miles on my...

Well, if you're drilling out rivets, be careful. I busted a drill bit that was big enough I didn't think I could bust it when I was doing mine, and the end still in the drill made a nice hole in the palm of my hand. I should'a propped the control arm on a jackstand instead of holding it with...

I had to trim the top of mine too. ...new motor mounts went in just prior to the purchase of the Dmax fan.

At 90 degrees ambient, the high side should be closer to 250. If both readings are low, and the temp from the vents is not cold, then you need more R-134. If both readings are close -- and the low is too high, it's likely because you forgot to install the orifice tube -- or the compressor is...

I got a 6' extension and mounted the existing Stanadyne PMD on a Fleabay heatsink and just set it in the bumper snout -- two years and 10,000 miles ago. It was installed on the truck with the new injector pump in 2003, some 60,000 miles ago. I carry a spare brand new D-Tech pre-mounted on a...

Don't forget to check with the county emissions station for advice on your conversion. Here in Davis County, we only have to pass a visual and a dyno smoke density test. I'm not sure how strict the visual is, or how they'd react when your vin comes up as a gas engine. My truck gets 15-ish mpg...

My vote is for a flaky solenoid -- what with the symptoms being intermittent and all. They don't always set a boost code when the boost is out of spec for short bursts. Of course, the MAP sensor could also be shot. A real time scanner is your friend. I bought Autoenginuity and can monitor...

Paid $7700 for mine 2.5 years ago. Turns out it had cracked heads and some bad bearings on the 49,000 mile Goodwrench 2003 engine -- even though it ran great. Not all is bad, though, since the block is one of the Navistar castings. I never knew the engine was other than original until after I...

10 or 15 years ago, the NV4500 was THE mod for Jeepers and others who upgraded their light-duty Jeeps and Broncos into something more suitable for trails. If I recall correctly, most all of those conversions required removing the damper from the NV4500. You might contact some of those...

I put one in my truck last year when I installed my new condenser. It works gangbusters at slow speed and at idle, but it doesn't cool the truck on the freeway. I got it at Autozone for about $15. I'll be swapping it out for a fixed OT.

I bought new headlights last year from JC Whitney like the ones in the photo. The plastic on them is a little thinner than the factory ones. There is a bump on the back that aligns the headlight with the sheet metal on the truck. This bump was located in the wrong place for my truck. I ended...

Update -- a self-repairing problem I can't get the glow cycle to be too short now. Go figure. When I got it started last time, and drove it to get the emissions test done, it ran fine once I cleared the codes. I think it must be the ECT sensor. Perhaps running it is good for it; I...

I have my Stanadyne PMD on a Fleabay heatsink in the bumper snout. I just used a little white Arctic Silver (cuz I have a big tube of it) and screwed it down. I just set it in the bumper behind the license plate. I was going to seal it with RTV, but I've never gotten around to it. ...never...

How many miles should one put on a new engine before switching to synthetic? I've got about 4K on mine.

I get right at 15 mpg in my truck at 75-80 mph steady freeway driving. I'd probably get a few more mpg's at 65, but I can't drive 65. ...especially for that 2 hour drive to Dad's cabin. Seems like tach reads about 2500 or so at 75, but I take that with a grain of salt. I have stock tires...

I know the answer is here somewhere, but the search function on this forum just stinks on ice. My truck runs great. Now that the weather has turned cold, when I go out to start it, the WTS light only comes on about 1-2 seconds and goes off. The ol' gal will almost start, but not quite...

I bought my injectors elsewhere, but I bought an FSD from them without any problems. If the SSL certificate is expired or self-issued (so they don't have to pay the fee to Verisign), then you'll get all kinds of dire warnings depending on your security settings. If you trust the company...

I pulled the PMD offa my pump, slapped in on a cheapo Fleabay heatsink, hooked it up with the 6-ft extension I bought, then stuck it in the bumper snout. It wasn't stalling before; it isn't stalling now. I keep the Dipaco as a spare. One day I'll drill and tap the other cheapo Fleabay...
