Bmw Valve Stem Seal Recall
Bmw Valve Stem Seal Recall ->>> https://shoxet.com/2tkQ5N
The problem: Drivers may notice engine misfire and smoke coming from the tailpipe upon startup, acceleration or deceleration. Additionally, the engine may run rough and consume excessive amounts of engine oil. These conditions have been attributed to leaking valve stem seals. When these seals leak, they foul the spark plugs, causing these symptoms.
Valve stem seals are enough of a common problem on the BMW N62 that a company, AGA, developed a specialty tool collection for the job. Their tool set allows you to replace valve stem seals without needing to remove the intake or exhaust camshafts. Prior to the AGA tools, replacing the valve stem seals could run $5,000-$10,000 to have the work done at a shop. Fortunately, since then, the prices at an independent repair shop with the AGA tools have dropped down to the ballpark of $1,800-$3,000.
Similar to the valve stem seals, the alternator bracket gasket oil leak is a dreaded common problem on the N62. This oil leak can be attributed to a design flaw and the use of a cheap gasket that degrades over time. Over time, the high engine heat causes the gasket to become brittle leading to cracks and oil leaks. Likely the only symptom of an alternator bracket gasket oil leak is physically noticing an oil leak from that area.
Finally, a problem that is a common on many BMW engines and not confined to mostly the N62. Valve cover gaskets are notorious for developing leaks on BMW engines. Over time, the engines high heat wears down the valve cover gaskets causing cracks and oil leaks. This may not seem a common problem on the N62 since valve covers should be replaced along with the valve stem seal replacement. However, the valve cover gaskets may begin leaking again regardless, and is likely more common for the lucky folks who have avoided the valve stem seal issues.
Just wanted the say the valve seal replacement job on the bmw n62 engine does not have to cost thousands. we rent out the all german auto bmw n62 valve seal kit that allows the car owner to replace the valve stem seals without removing the heads, cams or having to change the timing on the car, so for 220 you can get this major problem fixed at a fraction of the cost.
Replacing valve stem seals without removing the heads will typically require a couple of specialty tools to accomplish. On a given cylinder, you will want to be sure that both of the valves are closed. Then you remove the spark plug and fill the cylinder with air through the spark plug hole. This is where the first specialty tool comes into play. An adapter is threaded into the spark plug hole and then connected to an air supply. As long as the valves seal adequately, the air pressure in the cylinder will hold the valves in place while you remove the valve spring keepers, and the valve spring seals. This is a fairly advanced repair and I would suggest getting the assistance of a professional if you have any doubts. If this is something you want to have done, contact a certified mechanic, like the mobile mechanics available at YourMechanic.com.
Valves regulate how much of the fuel mixture enters the cylinder. The valve itself has a seal (and sometimes a protective sleeve) to help prevent leakage of combustion gasses and prevent oil from leaking into the main engine area.
Although bad valve seals and piston rings have similar symptoms, the time and costs of repairing them are quite different. Learning to pinpoint which one is bad by yourself will help save both time and money when taking it to a mechanic for repair.
If you have discovered there is damage to your valve seals, then have an auto technician install new oil seals. The cost of this replacement job will be between $900 and $1,800, depending on the make and model of your vehicle.
I would put money on your valve guide seals with the condition you described. Especially if the smoke billows out upon a cold start up and then goes away after a few minutes of driving. What happens is the oil settles inside the valve train area of the cylinder head after shut down of the engine and starts drooling downward, past the valve guide seals, running down the shaft of the valve and eventually into the combustion chamber and collects there until the engine is started again, which is why it smokes so much in the morning.. hope this helps.
My service mechanic has advised me to replace the engine as the issues with piston rings and valve seals are beyond repair. The replacement cost is around CAD 6000. It would indeed be wonderful if you can guide me on the best path forward as I intend to use this car for another six months to one year.
However, when the PCV system gets clogged, it can cause significant oil blowback. Rather than remove combustion gases, oil ends up getting sucked into the engine through the air intake. In most cases, resolving this issue simply requires replacing the PCV valve.
Faulty valve stem seals are another cause of low oil levels. While valve stem seals are meant to regulate oil consumption and valve lubrication, a broken one does just the opposite. A valve seal that has become worn or damaged may leak oil into the engine cylinders and eventually into the combustion chamber.

Sometimes an engine can lose oil due to a leak. An engine has many seams along the edges of its connected components. Those seams or gaps are sealed tight to prevent fluid leaks. But if those seals deteriorate, engine oil (also called motor oil) oil can escape. Leaks can come from around the oil pan, valve covers, intake manifold, or a number of other components that rely on seals to hold the oil inside the engine. A leak could also be caused by a faulty part, or even an oil filter or oil pan plug that is not tightened properly.

This BMW equipped with the N63 engine had an oil consumption issue where 1qt had to be added every 4 days and was blowing smoke from the tailpipe with a blue tint when accelerating post-warmup. This is caused by the aged rubber on the valve stem seals that hardens and cracks which will lose its ability to seal the valve guide. Bad valve stem seals will cause excessive oil consumption and can be identified by recording the level of oil loss.
We fixed it the only way you can fix this problem when it arises: by replacing the valve stems with new ones. First and foremost, the engine and transmission gets completely extracted from the car. One of several reasons why this is such a costly and laborious service. Detecting this issue early on will prevent a more costly repair as excess oil passing through the exhaust will damage the catalytic converter overtime.
Bottom end was rebuilt and broken in properly. Top end was also redone. A leak down test is in order (can any shop do this for me). I just want to be sure before I take back the car to the shop that did my head work that it is indeed the valve seals/guides and not the bottom end. What happens is when I go highway speed 4.5k+ rpm 80 mph or more, let off the throttle until it goes to 3k rpm, then hit the throttle I get a puff of blue smoke. I have a catch can and my plugs don't have any oil on them. Although I went through two oil filler caps since I noticed leak from up top.
Smoke on deceleration is a clear sign of valve seal and/or valve guide leaks. On deceleration the choked engine creates a vacuum placing demands on the seals and guides. A leak down test may be used to diagnose ring leakage or valve leakage but will not provide direct evidence of a valve seal or valve guide wear or improper fitment. A L MAY seat well enough to provide compression may not show up on a leakdown or compression test. A valve guide or valve seal is not related to compression.
Valve stem seals are very easy to tear or damage during installation. Guides can be new, but if the valve stems have significant wear (especially nonlinear irregular wear), new guides may not curtail oil leakage or seepage to the extent expected. Depending upon exactly what work was done to the valve train, things may have been put together using outside tolerances. This could be done deliberately to reduce any need for break-in or simply to reduce costs. If things were put together by cutting corners, greater tolerances mean greater chance for oil leaks. Using heavier 20w50 oil could be critical. If break-in procedure has been accomplished, have you changed the oil to fresh undiluted oil 59ce067264
