    Oil Pressure Issues?

    It's got to be a bad sending unit or gauge because now right after starting it the oil pressure drops to zero but there's no knocking or ticking and the truck runs fine, well it's running a bit rough but I don't think it's anything to be concerned about. I say that now but who knows, lol.

    Oil Pressure Issues?

    Not using coolant. When the gauge first started dropping to zero it was after 10 miles of driving, it's now dropping to zero after just a few miles. I read that a spun rod bearing would cause low oild pressure but I would think it would be a constant low pressure, not bounce from normal to zero...

    Oil Pressure Issues?

    It must be burning oil, I don't see smoke or smell oil though.

    Oil Pressure Issues?

    If it was a faulty sensor would the gauge still move when given RPMs?

    Oil Pressure Issues?

    Sitting at a stop light my oil pressure gauge on my 2002 4.7l RAM suddenly dropped to zero, I reved the RPMs and the gauge shot back up to normal. It was fine until the next stop light then it did it again. While it's doing this the engine sounds and runs perfectly normal. Got home, checked the...

    I've seen on YouTube people using and/or talking about technical spec sheets they have on their vehicles but I can't seem to find online any detailed tech specs? Like, what model number the AC compressor is or the alternator or a detailed color under dash wiring diagram. Where are these guys...

    Viper 300ESP Alarm Install 02 1500 Questions?

    I'm trying to install a Viper alarm in my truck but can't find a good ignition wiring diagram. I'm just using the ignition/starter interrupt but I don't know which wire under the dash to cut. Any help with diagrams or experience would be great!

    02 RAM Kill Switch?

    I want to install a kill switch on my 02 RAM but finding a color coded wiring diagram is a problem. The last kill switch I installed was on my 74 C20 454 and it was simple but I'm a bit apprehensive on messing with the wiring on a computer controlled vehicle. The image below is obviously not...

    02 Spare Tire Winch/Hoist Mystery!

    After cutting that piece off a member of another forum posted a pic of his spare tire winch and it just so happened to have that same exact bar welded on the winch so it is OEM. Perfect example of why getting a second opinion before cutting off OEM parts is always a good idea, lol.

    02 Spare Tire Winch/Hoist Mystery!

    Thats what I was afraid of. Time to buy a cordless grinder. I'm still puzzled on what could have been more important than the spare tire?

    02 Spare Tire Winch/Hoist Mystery!

    Just bought an 02 RAM 1500 4.7l a few months ago without a spare tire, didn't think much about it until I came across another set of matching rims and tires. I thought oh good, I'll basically have four spare tires, I'll put one on the truck and store the other three. Well after winching up the...

    Can Marvel Mystery Oil be use Instead of Motor Oil?

    It was a stupid question, no I did not run MMO in my engine instead of motor oil. I actually used Royal Purple synthetic HPS 5w 30 motor oil with a WIX XP Heavy Duty filter. I've never heard of Redline motor oil so I bought the Royal Purple. What do you guys suggest?

    02 4.7 I Bought Two Bad Vapor Canister Purge Solenoids in a Row?

    I replaced the VCPS twice on my 2002 4.7. First time I bought the VCPS off amazon, I removed the battery cables, installed the VCPS and the CEL was off. The next day the CEL came back on so I replaced it again with one from Autozone but the CEL came back on 3 days later. The VCPS was installed...

    Can Marvel Mystery Oil be use Instead of Motor Oil?

    I have an 02 RAM 4.7 with 139k miles that has cold start engine clatter. Only last for 60 seconds or so then runs great with plenty of oil pressure and power. My question is, all my life I've heard old timers talk about how good Marvel Mystery Oil is as an additive but after an oil change can I...

    2002 4.7 Engine Chatter at Start Up w/ Good Oil Pressure.

    If the timing chain tensioner makes noise until it gets oil wouldn't that mean the oil pump is weak? The oil pump should start pumping immediately the second the engine start turning over. The analog oil pressure gauge on my dash takes about 2 seconds before the needle shoots up to the middle of...

    Hello guys new member here, I hope you can help with my issue. Like the title says, when I do a cold start the engine clatters for a good 60 seconds then slowly goes away. When at operating temperature the oil pressure stays normal. The truck has 138k miles and runs great but I can shut it off...
