Minor 'hiccup' every now and then while driving

Kinda like a misfire/loss of power... keep hearing about the camshaft position sensor and its buddy, the synchronizer...

Also I keep hearing about bushings wearing out in said synchronizer... maybe change those out for needle bearings for longer life before you even pop the new one into the engine?

So I have to spend 85+ bucks on a synchronizer?

If the drive gear is still good on the factory part, why not swap it onto the Dorman to replace the 'crap' gear, along with putting the needle bearings in place of the bushings and theoretically gain infinite life?

Or did someone already try to do such a thing, or is it completely unfeasible?

As for the oil gauge, I ditched the crappy "You're fine, you got 7 psi" factory part for the cheap HF mechanical gauge that comes in the set of three gauges with the mounting panel... reads consistently and I'm sure it's more accurate than the factory gauge...

I don't trust idiot lights and H/L gauges. A cheap aftermarket gauge is more accurate than the aforementioned gauges/lights.

Reading 20 psi at idle (about 900 rpm) and about 50 at 2500 rpm. The factory sender was saying I had about 1/8 above "L"...


... WTF I type up these for their appropriate threads (oil pressure gage, and the one above was supposed to be a new thread) and they show up in this thread?

Guess I need to figure out what the sam hill is going on around here.

You could set up an actual gauge. Mine has the "dummy" gauge. When I found this out I set up a gauge pod with an actual read on oil PSI. You would be surprised what oil PSI is at 5K RPM's on mine. Since I saw that on that Pod, I dont take it above 4800 anymore. Im betting it was just a glitch with the truck. Mine has it's quirks with 141K miles. If it keeps doing it then I would troubleshoot. Could be the first signs of a bad sending unit too or worse.

Yeah, I was really surprised that the factory made the stock gauge look good at 6-7 psi...

Put the gauge on, and now I get about 85 psi at 4500 rpm when it's warmed up, 20 psi at idle, 50 at 2500 rpm.

Plus it'll be sure to tell you if your cam synchro is bad, maybe even fluctuate to warn of impeding doom from the synchro on its way to going **** up.

Just a note. I recently replacer mine and 292K miles and it wasn't bad at all. I'm glad I replaced it but it didn't change the issues I was having.

More to the point, my oil pressure would not come up in the morning right away. While I was doing the cam sensor I replaced the Oil pressure sending unit. It works just fine now.

I inherited the truck at 275K miles and my son ended up with my 2003 Silverado. He told me to give the Ranger away. :) but it was better than my yard truck so...here I am. LOL

Well, in that case, I'll just de-carbon the combustion chambers... that'll be after I fix the blasted exhaust manifold leak. A couple bolts fell out, and the gasket blew out on the pass. side manifold. It's insanely deafening. Can't hear nothing but the exhaust pulses of that thing in my ears right now. Next up after that, it'll be the DPFE that I keep hearing about... mine is the factory metal cased one...
