I think I have an oil lifter problem. But my montana runs really well.
Haven't tried anything yet. But when I start it up, it has this loud ticking noise. And after the engine warms up, the ticking noise is very minimal. And the oil reading on the dipstick is over half way up the stick. Does anyone have any suggestions ?
Re: I think I have an oil lifter problem. But my montana...
Well you have a car that has trouble with that engine they blow intake manifold gaskets some where between 80,000 and 120,000 miles like clock work ,it should have been a recall . How dose the oil look? is it milky . How did it get so much oil in it . ? dose it get hot on you and leak anti freeze ? How many Miles dose it have on it? If you are leaking anti freeze into the oil or out side on block you need to have the intake gasket replaced if it is not to late Is the ticking noise a rod knock? if your handy check out the forms on your motor if not get it in to the shop asap.

I have cured just a few using a real AC Delco filter and synthetic 5w-30 oil. GM recommends using only 5w-30 oil in your engine because other weights can cause air to get into the lifters during start up and cause lifter noise.
try draining the oil to the required limit , there will be a min and max mar on the dipstick,the noise on start up is the excess oil trying to be pumped around when it is cold , also excessive oil can leak out of the main crank seal into the clutch housing and cause damage there
Your engine code (DTC P0442 Evaporative Emission (EVAP) System Small Leak Detected ) should not have anything to do with a ticking sound. The evaporative system keeps you from having a gas smell under the hood and in the car.
As far as ticking goes ... it could be many things. You are correct, it could be lifters. If you take a long screwdriver and with the engine running place the handle end against your ear and touch the blade end to the top of the valve cover the screwdriver will act as a stethescope. If the ticking gets a lot louder somewhere on the valve cover then yes, you have a lifter making noise. If the motor ran really low on oil, and then one or more lifters started ticking you can try running about a half quart of transmission fluid in the oil for about 15 minutes at ididle while gently changing the rpms between idle and about 2500 to see if it loosens up the lifter(s). Change the oil after you do this.
To test the PCV valve, with the engine running pull the PCV valve out of the valve cover (leave it attached to the vaccuum hose) and place the tip of your finger against the now exposed tip of the PCV valve. It should make a snapping noise and **** your finger against the opening in the valve. If it does not, then make sure the vaccuum hose does not have a leak in it. If the hose is good, shut the car off, remove the valve from the vaccuum hose, and use some carburetor spray and clean it out. I clean mine each time I change the spark plugs. If the valve is stuck or clogged this could be causing the oil pooiing problem in the air intake tube you describe from excessive crankcase pressure.
If you still have not found the ticking noise, it could also be in the lower end of the motor. This is the only "bad" place for it to be out of what I have described. If it is a lifter and the noise is not really loud, it is not dangerous to drive.
Prognosis is really bad, hate to tell you. Ticking comes from the valve lifters, losing lubrication due to lack of pressure and running dry. At redlights, when revs are at idle, oil pressure drops a lot, and engine really suffers. Have the vehicle taken immediately to a shop for proper diagnose and to see if engine can still be saved. The loss of power comes from the valves not actuating properly. Hydraulic lifters need oil at a decent pressure to "charge" , and if not charged, they will stay compressed, ruining valve lifting operation.
this is a very common issue with any of the bmws with n52 and n52k engine,as long as oil level is ok and is being changed regularly than than a "blleding proceedure" may solve this problem, when the engine has been running long enough that it is hot run the engine at idle to 4500 rpm for 10 to 12 min to start, if is still present after this attempt again.It has been said that this could take up to 30 min at longest.The reason for the ticking noise is a very tiny air gap in the hva and or lifters, try this and if does not work than the lifters should be replaced, although this noise doesnt really hinder the performance it does take away from driving such a nice car and having a loud noise come from the engine, good luck
YOU NEED TO ISOLATE TICK TO FRONT OR REAR BANK OF ENGINE..A MECHANIC'S STETHOSCOPE CAN HELP YOU ISOLATE..THEN REMOVE FRONT OR REAR VALVE COVER AND PUSH ON EACH ROCKER ARM..IF A LASH ADJUSTER(LIFTER)IS BAD,IT WILL BE SOFT OR COMPRESS WHEN YOU PUSH ON IT..LIFTERS ARE IN ROCKER ARMS ON A 3.0L AND IN BLOCK ON 3.3 AND 3.8L ENGINES
I would have you oil pressure checked. The oil pump or bearings could be going out. The lifter noise on this car usually will go away faster then 5 minutes. I think the noise is lasting a little to long.
