We took a trip last August to Jax. Its anot 200 miles away. When we got back home we had an oil leak and a tapping noise had to replace the oil pressure switch. IT took care of the oil leak and tapping.
This past week we went to Daytona Beach which is about 250 miles away. When we got there we developed an oil leak and a tapping noise and had to have the oil pressure switch replaced once again and again it took care of the oil leak and tapping noise.
WE came home yesterday and this morning I got up and cranked the van to go to the store and it had a tapping noise but no oil leak.
Well My husband went to the parts store and got another oil pressure switch and bought a socket and replaced it himself.
Apparently it wasn't the oil pressure switch this time because its still tapping. Any suggestions on what it might be thats causing the tapping and how can we tell if its getting oil to the the engine.
It sounds like the oil pressure is too high.have someone check for clogged blow-by hoses or connections.some blow-by connections have screens in them tha can become clogged with dust or oil deposits.also check for places where dust can enter into the engine,such as,air filters and air hoses that may be loose or damaged.

Are you absolutely certain the noise is lifter tap and not an exhaust leak? These are pretty well known for breaking exhaust manifold studs, or even cracking exhaust manifolds. The noise will be present on a cold engine but might go away as the engine heats up and the manifold expands. Maybe that's why it seems to go away after adding additives or changing the oil. It gets just enough heat in the engine to fool you in to thinking the issue was resolved by adding the oil/additive. Are you always adding to a cold engine?
I had what sounds like the exact same problem. It was an exhaust leak from the left (driver's) side exhaust manifold. This engine has a history of the manifold bolts breaking and causing the exhaust leak. The engine is also used on some Dodge vehicles. It sounds like a tick and I almost mistook it for a bad lifter. I took it to the local Jeep dealer who confirmed the exhaust leak. I replaced the left manifold completely and replaced bolts/gaskets on both sides (left/right) and it fixed the problem. Be careful, as the dealer tried to gouge me on the price. You are looking in the ball park of $600 parts/labor. I got parts for $120 and it took the better part of a work day to do the job.
both engines on these sentras are hydraulic and no adjustment is necessary. if youre getting some tapping noise, try a good engine flush and idle till the noise goes away. the last time i did one of these, it took 2 hours for the noise to cease. drain the oil and use a nissan oil filter and probably 10w 40 oil. you should be fine. cheap fix huh?
take your truck to a mechanic with a smoke machine. He can add the dye and send smoke through the engine if there is a keak the smoke will exit the engine that is were the leak is the dye will tell the mech. the very spot the oil is comming from
It looks like you drove your car with no oil in your engine, unfortunately you should have stopped the moment you started to hear the "rapping noise" since you could have severely damaged your engine. If the noise continues even if you have a normal oil reading you most likely would have to overhaul your engine since by driving it oil dry several parts may have resulted damaged.
Sounds like you spilled a little oil on the engine when you added oil. Don't worry it will burn off by itself as long as you don't have an oil leak somwhere. If the smell doesn't go away after running the engine for 50 miles or so have a shop check the engine for oil leaks.
Got my GL 320 CDI in Jan. Drove it to Amelia Island, FL this Easter from Michigan and had 2500 miles at the time. 500 miles into the trip, 2 problems showed up. 1. low oil level warning indicator went on a total of 6-7 times for the round trip. I suspect the dealer I got it from did not hand over the veh to me with a full tank of oil. I had to put in 2 quarts on the way to FL. Had it checked at a MB dealer in JAX and they said there was no leak. The low oil level warning came on again on our trip back to MI but the oil levels were full. 2. The worst problem was that the shock absorber on my right rear wheel was defective. Noticed the problem on the way to FL when I stopped to check the oil level. Watch out for a metal-to-metal grinding noise. It is not the brakes! We had a fully loaded vehicle with 4 occupants and a Thule luggage carrier on top. I didn't know the shock absorber was the problem until I had the Jacksonville dealer take a look at it. Found out there are over 70+ SA's on backorder across the US. Tells me there may be a defective shock absorber problem. Since I needed a new one right away to make the return trip to MI, the dealer pulled a GL off their lot and transferred the SA to my vehicle. Thank God! Drove fine the rest of the way ty that may stress the front end bushings, etc.
