Valve stem seals done for $2500!

For those who don't know me.... I'm a BMW master tech located in Long Island, NY who has helped out many forum members here in the past (just do a search and you'll find me). I've been seeing many posts about the common valve stem seal issue with the N62 and N62TU engine. Symptoms include excessive oil consumption and severe smoking from the tail pipe. I'm offering to complete the repair for $2500 total (parts and labor). This includes new valve cover gaskets, new upper timing case cover gaskets and valve stem seals of course. I would need 2 full days to complete the repair, I'm available on weekends (I work at the dealer during the week). Most dealers charge anywhere from $8,000 to $12,000 to have this done, so here's your chance to save a ton of cash! I've had someone drive over 12 hrs to meet me and to have the repair done, it was well worth it for that customer. You guys can post here or PM me. I'm also a forum regional sponsor, so my contact info is located in the section of the forum. Thanks!

For some that don't know, this is a very good price. Since you are a BMW Tech, what is your take on the secondary air passages that become blocked? Is there a repair that you can perform while you have the valve covers off. I know that you will probably have to remove the intake, but do you have a repair procedure that can be done without removing the heads? This is becoming a fairly common problem, so what are your thoughts? Are these 2 failures due to extended oil changes, or due to cheap & non-ethanol fuel? I am also surprised that your dealership allows you to do repairs on the side!

I am not trying to put you on the spot, but I would like to hear your thoughts?

Thanks

I hope that I do not have to do this job, but it would be better if you were here on the West coast.

The secondary air issue is a separate repair. Typically we remove the heads to clean out every last bit of carbon. I'm currently working on a more cost effective repair that does not require removal of the heads. The cause for the blockage is due to the exhaust valve stem seals leaking oil down the back if the valve and carbonizing when it hits the relatively cooler air providing by the secondary air pump. I don't think the extended oil interval is the cause of the seal failure, I've done them on cars with as little as 45k miles.

A lot of BMW's have valve stem failure after 80k miles or later. When the valve seals get hard, oil starts to seep passed the seals. When this happens, the engine will start to smoke after stopping at a stop light. In my experience engines that have been abused by a lack of maintenance , typically will have the seals harden from oxidation of the oil. This can happen in any manufacturers engines, but a BMW cost a lot more to repair. You can see a lot of post on the 7 Series forum.

The clogged air passages in the heads, are another high ticket item to repair. Finding a way to clean the passages without removing the heads, would be a huge cost savings. I have seen where a couple of people on the 7 series have been able to soak the passages by removing the intake, & getting them to clear without removing the heads. I think that there is a lot of trial & error on this repair. A proven method would be a good find! I hope I never get to experience either of these problems

Here's a close up pic of an old seal next to a new one, the difference is pretty clear

For future reference, do you do all kinds of repairs, brakes,oil changes, tune-ups, etc.? Where in L.I. are you located?

Nice to know. I'm in NY and know a lot of BMW owners that would welcome a really good shop. I know a couple of folks out in Queens that take their cars to a shop out there as well. Might be your spot. PM me.

BMWOEM1 would you recommend an engine flush or fuel system cleaner, to avoid this repair or after the repair is done.

Good to know. I'm up in Dutchess County. But I am down at Long Beach a lot. I will look you up when I need service. Thanks.

A flush or cleaner would do nothing to prevent this problem. From my experience its just a matter of time before the valve stem seals leak. It seems to be just poor seal design/engineering. Prolonged idling time also seems to accelerate the problem (excessive heat).

Bmwoem1 ,I'm modded a stock tstat to run 95c.As you know this is 10c cooler than stock.Ive been running this way for 6k miles with no apparent problems.My UAO shows no unusual wear.I did this in an attempt to slow down seal degradation.All the seals.Dont know if it will help but let me know what you think.Thanks.

Learned this trick from LS engine vette guys.Took the element off the pin of the tstat and put a shim down the hole.Had to play with shim length to get valve seated exactly where I wanted.

Another approach http://www.bimmerfest.com/forums/sho...d.php?t=665965 page 48.Very large thread on this. A certain member stated he was having custom TStats made but that seems to have vanished.??Anyway a couple of different ways.To lower operating temps on M62 seemed to be a common mod.I seem to be one of the first on here with a n62?

I don't think this will help because its the engine oil that needs to be cooler. The oil cooler has its own thermostat. So the lower temp coolant thermostat may delay the time it takes for the oil to get hot, but eventually the oil will reach the same temperature as it always did. Also, it is the exhaust valve stem seals that fail, not so much the intake side. Due to the hot exhaust gasses squeezing past them, the exhaust valves run at a higher temp than the intake, which why those seals fail first. The lower temp thermostat should not affect the combustion chamber temp/exhaust gas temp too much (if it did, you would notice a decrease in power/mileage). Then again... The thermostat mod can't hurt your engine so it could only help

Thanks Bmwoem1.I have noticed a nice improvement on throttle response after complete warm up.Also hoping it might help with other seals.Sorry to keep hounding but do you think more frequent oil changes or other types of oil will help with valve seals?Thanks again.Oh Im actually in a 545i but as you know all the same but my car didnt get an oil cooler.I have looked at after market.
