I have an 02 durango & today out of no where it started knocking... One person said it sounds like rod or lifters... Bout how much would it be to fix? Or am I screwed

Gotta get an exact diagnosis first. If you spun a bearing on a rod or crank, you may just need a lower overhaul. If there are a lot of miles on the engine then get a complete rebuild. An inspection of your engine will determine what damage has been done internally. Until that is known there is no way to estimate the costs you will face.

Where is the oil pump on a 318,1992 dodge ram 1500

Inside the oil pan. Not an easy job. Just a note... Probably not the pump. Probably is the main and rod bearings on the crankshaft. Pull the engine. If really high miles rebuild the engine or replace it. If low miles (like 100,000), replace the crank and bearings. Unless a bearing has spun. You would know because there would be a constant knocking in the engine lower end.

Mechanic book

which engine? size?
the ECU nor any lamp can save the engine with no oil or too low
or never changed out.
you missed, week level checks.
and if levels drop fast (as it will driving real fast)
you check more often, in fact you learn what your engine needs.
my guess is loss of oil pressure,
the idiot lamp( just name) comes on with its TOO LATE..
on most cars made.
get a real gauge called oil pressure.
or the engine overheated
or just bad luck.
what seized, cam , crank or rod bearings.
the machinist will tell you for sure what failed.
the pump or low levels.
push rod engines. the rear rod bearings like to fail first (low oil)
then on overhead cams, they bite dust first. (top end oiling can fail easy)
also, on the last rebuild did (no 2 before) the PO, ran water for antifreeze this cause the internal freeze plugs to pop and
water in oil and rear rod spun(seized)
water makes really poor oil substitute.
when you take it down there are tons of clues.
blue metal.
oil looks like chocolate milk shack
bearings spun ,cam bearings gone.
cracks in block and head.
ever inch checked then pressure tested before rebuild.

Spun bearing

You are up for an engine rebuild. Remove the engine and turn up side down in a stand. Remove the sump and find the failed bearing by taking off the big end caps. If you find a con rod damaged you will have to remove the head and that piston and replace the con rod. If it is a main bearing that has spun you should only have to replace the crank shaft and fit new bearing shells Either way you will need another crank shaft. Check the price of a low mileage engine from a wrecker as it will be quicker and possible cheaper in the long run

Error code p1519 97 cobra svt

Check the actuators for the variable intake runners, that is what this code means. Many times the little linkage rod is disconnected.

How do you repair spun bearings on a 1994 Mitsubishi eclipse Gst ?

if the bearings or even one bearing has spun, the lower end of the motor needs new bearings and the crankshaft must be "turned" or resurfaced.. this requires pulling the engine... if you drive this vehicle in this condition, you will have catastropihic engine failure which would totally destroy the motor probably.. If you or someone has the expertise to remove the motor, putting in a "crank kit" is not difficult for anyone with a little mechanic experience.. but, basically, this is time to rebuild the motor whether you just do the crank kit or go ahead and go all the way with it since you already have it out and opened up...

How do i stop my rods from knocking

There is no cure for that other than taking out the engine and tearing it down and replacing the rod bearings. There is probably too much clearance between the bearings and the crank journals do to worn bearings.

I have a spun rod bearing, and a scored crank

Talk to an engine rebuild shop near you. They should be able to save your crank if it's not broken, and get you a set of bearings and piston or anything else you need. They'll be in the Yellow pages.

Continued question,spun bearing...

It would not Hurt to Change the Oil Pump But, You Probably do not need to. Use Valvoline Full Synthetic 10-40. If you have no other Problems with it right now Do not Change anything, Just do the Crank kit and it will be Fine.
