#305 of 375 no oil pressure by wiremap Nov 04, 2008 (8:57 pm)
I just bought a 99 Dakota with a 3.9lt and 63,000 miles in it. The truck was not used for about a year at the time I got it. I have change the oil and filter as soon as I've got home. Couple days ago the pressure gauge hits 0 for a couple of seconds and then got back to normal. It does that twice on the same trip. Tonight it goes down to 0, never came back to normal, I was close to my house so I just got there. I turn it off, wait for a couple of minutes and start it back. The engine start to make some noice (I guess it was the lifters). Any advice from someone. Should I replace the pump and start praying?

Replying to: wiremap (Nov 04, 2008 8:57 pm) Oil pressure falling that rapidly then rising again usually indicates a clogged oil pump inlet screen. I suppose you could have a bypass valve that sticks intermittently, but I've always seen them stick in one position and stay there.   Looks like your going to be pulling the pan anyways.   Regards, Dusty   P.S. I once found an oil pump screen blocked by a heavy paper return parts tag on a '70 Ford. That engine had 16,000 miles on it before it seize from lack of lubrication.

#312 of 375 1997 Dodge Dakota Engine/Electrical Trouble by nenisi Dec 13, 2008 (7:43 am)
#313 of 375 1997 Dodge Dakota Engine/Electrical Trouble by nenisi Dec 13, 2008 (7:43 am)
I have a 1997 Dodge Dakota Sport, V6, 4X4. When the outside temp falls below 32 degrees I have a problem. Engine starts fine. After 10 or 15 minutes of driving I sometimes cannot go uphill over 15 miles an hour. Downhill is worse, I leave off the gas, the RPM's fluctuate by as much as 1000, it then backfires. I have replaced the cam sensor and the air temp. sensor. If the check engine light comes on, it signifies the cam sensor. HELP!! I'm at my witts end! Do you think it could be the crank sensor or possibly the temp. sensor? Replies to this message: paintballfanxx (Feb 20, 2009 3:33 am)
#314 of 375 dodge dakota, dodge ram charger piston swap by 95f150 Jan 19, 2009 (7:42 pm)
well okay, first of all, my first post. and i need some help here. my dad has a 94 dakota 318 4x4. pretty nice pickup when he bought it. well the bad part is he bought it for me to drive. and as i am 16 years old livin in north dakota, it went through more mud holes than anything pickup i have seen. it has been raced, and the engine has gone to hell and back. and i gotta say, that thing just doesnt want to be stuck. i think it got stuck 6 times in a little over a year, which is a lot better then my ford. anyways, he also has an 85 dodge ram charger, 318 4x4 that doesnt have insurance anymore, so it basically sits in the driveway. well we have swapped the engine in my ford twice, as i have blown in up twice (water in the cylinders both times). the second time we took it out we just replaced cylinders. and now he wants to take the cylinders and connecting rods, possibly more engine parts out of the ram charger engine and put them in the dakota. but as the ram charger is carburated and the dakota is fuel injected he doesnt know if they will swap. i mean he basically wants to use as much of the carburated engine as he can, as that thing just wont ever die. so if you could it would be nice if someone could tell me if the pistons, possibly the heads, oil pump, and other engine parts would swap into a dakota engine. thank you and sorry for being so long winded. its kind of my downfall to forums.
