Re: I think oil pump went out, is ti inside the oil pan?
Fishinic: the oil pump is on the end of the crankshaft at the front.
you may have a clogged up screen at the bottom of the oil pick up tube which goes to th bottom of the oil pan.

kick the little guy out with the hammer he ain't paying rent
could be a lifter
is the oil up to level?
is the knock loud?
drain oil and see if you have any metal fillings
drop oil pan and check for loose rods
Suzuki should have stayed with just motorcycles. Anyway, You just had the oil changed. Check and see if they changed the filter also. They may have forgot or were just to lazy. Just a chance the oil filter is bad, I would replace it again(is the oil clean on the dipstick?). Add a higher viscosity oil. At 67,000 miles, you would have to drive dirt roads all the time, with no air filter to get sludge to clog the head ports. Which is slow drain of oil to the pan. The oil pump? well it could be, most likely not. I would say the oil sending unit is bad, but the knocking noise kind of throws that off. Knocking is bad, if it happens again, pull off and shut the engine down. One other thing to watch is the temperature gauge. getting really hot will cause knocking. Check coolant level and the thermostat.
ionMr. Hugo. what to what you do have is the viscosity of your engine oil. Most probably is either long mileage used engine oil and due to that oil mud built up inside the engine, in the oil pan and most likely close to the oil pressure pump filter reducing the suction and that is why you do have cold lifter knocking,as the engine oil that time is thicker and when it gets hot become thinner and lifters stopped knocking. My persona advise do flush the old engine oil using ( RESTORE MOTOR CLEANER ) pour it into the engine old oil,start the engine in idle and few times reving it for 40 minutes. Then drain it and renew the engine oil with new and recommended engine oil for your engine,by renewing the oil filter as well. Also in the new engine oil put also (RESTORE FRICTION REDUCER ) additive and run the engine.For next oil change please do it every 5000 km ( 3000 miles)
I would be checking the oil pressure with a mechanical gauge . If you have used the correct viscosity oil the lifters should stop being noisy after a minute of starting the engine . If it is the pump then you will have to replace it but it may be a loose oil pick up line or loose pump allowing the oil pressure to escape back into the sump.
If it is the 3.0 you may have heard the lifters. but sometime when you leave an oil pan off for very long you will lose your prime from your oil pump and it will take an few sec to get primed. how long did you let it run for. did the the knocking go away
Before driving it anymore I would have someone test the actual oil pressure using a mechanical test gauge to see how much , or little, oil pressure you actually have. The knocking noise could be a hydraulic lifter that is partially collapsed due to low oil pressure or a rod bearing that has been damaged from low oil pressure. If it is just a lifter that is making noise then there's a pretty good chance that the lifter will quiet back down once the oil pressure is normal again. If it turns out that your oil pressure is normal both at an idle and at highway speeds then the noise may be unrelated. You can cause some serious damage by continuing to operate any engine that is low on oil pressure even if the dipstick shows it to be full of oil. Hope this helps and good luck!
usually it comes on when you are low on oil, check oil, if it is good then there may be something wrong with the sensor or the pump inside( you will usually hear the valve/lifters knock) the oil pan. Hope this helped Tim
have you had oil changed recently? if so look to see if oil pan plug is in tact. if so, check oil on dipstick. the problem is the car has no oil pressure. if the oil level is good the oil pump is bad. good luck!!
