E70 Valve stems seals and engine rebuild - done right
Dealer wanted about 11K and Most INDI shops can’t do this job right. I knew about an INDI BMW master tech located in Long Island, NY that does the job for about ~$2500 BUT just changing seal valves would not be right fix BECAUSE if you don’t put new valves / gaskets / water pipe / all bolts and machine shop rebuild cylinder heads you are doing a TEMPERATELY fix. Luckily I been going to same INDI shop for last 3 years with my E63 and now X5. After speaking with Mike - shop owner and master mechanic he agreed to do full job for about $4200. I was super happy to get this price!!! Fast-forward to now – Car was in the shop for about 9 business days. I got it back and drove it for about 500 miles. Not a single problem. Engine sound like a brand new and pulls Hard! I love it !!! I feel very confident that my car is good for another 100K miles. Take a look at the pictures attached and ask any questions you got about rebuild. If you need your valve seals done go to see Mike – MP Motorsports / 347-725-4228. Shop located at Queens NY. Getting valve seals done right is no longer an impossible task but still somewhat expensive … LOL Cheers mates : ) |

Sounds like a good experience. Well done. What were the symptoms you were having? I've got 115k on mine.

Wow thats a big job indeed. Good time to put headers on it (if they are available).

Symptoms of valve seals failing – excessive oil consumption and severe smoking from the tail pipe after few minutes of idle. I will post a video when I find it.
Perfect time to put new headers if you got them |

With all due respect, hogwash! You don't need to pull heads to fix valve stem seals. And, failed valve stems seals does not mean there are other issues with head or other components.

Davidf - why would you not rebuild the heads if you already doing the valve stem seals ? If you already investing this much money in the engine rebuild I thing its very appropriate (unless you want to fix just enough to sell the car)

Because simply replacing the seals is usually all the head needs. I proved this to myself after replacing the seals on my 545i. New seals solved the oil consumption issue and the plugged secondary air port issue (not applicable to newer V8).
With AGA's tool, the seals can be replaced without removing the heads. Time and money saved. And a DIY task. The smarter choice in my mind. I,suppose it is possible that excessive guide wear could be an issue; but, not the case on my car with 125k at time of seal replacement. BMW provides a spec on determining allowable guide wear by measuring side to side movement at the top of the valve stem. |

I was about to say the same. it looks like 'make work' to me. We used to hold the valves up with compressed air while changing seals in the 'old days'

Another reason I would want to avoid pulling the heads is the real risk of pulling the head bolt threads in the aluminum block when you torque the new bolts down. If it was me, I would Time-Sert the block before re-installing the heads.
