By your description of blow-by. my guess is If the fueling is half-decent accurate, which the fuel mileage is pointing to, then either. 1) the plate on the bottom of the "keg" is sucking crankcase fumes, or 2) the oil rings are, wore out or stuck, or 3) the compression rings are, wore out or...

I'm guessing, at least 3/8ths inch. IIRC, I paid $495 for them, in 1999, plus shipping into Canada; and the dual 3" exhaust was about the same. This system is still on the car with only some minor rust-thru in the valleys of the merges. Car was a DD until 2005/6. Every fall I would swap a 318...

IDK if there is or not, I kindof doubt it. I don't think there can be. But there is a formula for computing fuel consumption to Power. As in, if your particular chassis requires "X" amount of power to go, "Y" mph, then the amount of fuel for that situation, can be calculated. Somewhere I once...

Yeah, the secret is in the gaskets, and having thick flanges. The hot/cold cycles just do that. My TTI headers have about the thickest flanges I've ever seen, and the last set of gaskets that I bought, are the the thickest I've ever run. Together they are the best sealing chit that I've ever...

Sac City Iowa?.

Yahbut, What is the ECM reading? As far as I know, there's two different sensors; one for the gauge and another for the ECM. You can't know what the ECM is seeing, until you put a scanner on it.. I'm still stuck with why the CEL didn't come on with the headers sucking air. I'm pretty sure...

Well; that should have triggered a lean condition, most likely by turning on the CEL, and registering a code or a couple to several codes. I cannot imagine a situation why it would not turn the light on, unless the engine is semi-permanently stuck on the warm-up program. If it was in limp-in...

I have heard that you can download an app for your phone, but I'm not a techno-geek, so you're on yur own with that. lol The problem with running high tire pressures is two-fold; IIRC you are running 20s? 1) the ride with low-profile tires is harsh enough; and it only gets more harsh, with...

Well, assuming the O2s are working as per their design, and with no cell, me the carburetor guy, hasn't got a clue how you can coax anything more out of the engine, with the factory ECM, other than ; making sure the cylinder pressure is up and even, and the fuel pressure is on spec, and The...

aha! Well, that's good then, I guess. As I recall, you said the engine has I'm assuming then, that the Headers have Working 02s mounted in them, wired to the ECM, right?

If the truck does not have a CEL (check Engine Light), then how does it communicate to you that one or more of it's sensors are malfunctioning?

The faster you drive, the more power it takes to overcome the air resistance, which is guaranteed to cost you more gas. But as we found out many years ago, if the engine becomes more efficient at the higher rpm, then you can break even or even win. What I'm talking about is early 60s Big-inch...

Pardon my ignorance, I'm a General Automotive and Light-Truck mechanic, now retired; but what is rcsb? Is that truck a stock 5.2 Magnum/Sequential injected/overdrive? or a transplanted low-perf LA318 carbureted? How fast are you driving and how high is the engine reving? I'd start with a...
