Some people asked me why I had to touch cylinder heads - Reason for rebuilding cylinder heads is because valve guides were worn and thus by just changing the seals the problem would re surface in the near future ��

Worn valve guides at 100k! I would be worried there are other issues that will surface with your engine as it seems to me it was not well cared for. Out of tolerance valve guide wear at that mileage is unusual. I hope you got the real story from the service department/shop.

Most others wont need to go to your extreme to fix valve stem seal issues and, it will still be "done right".

I must be really old, I've used oiled up cotton clothesline. With piston at BDC, feed as much oiled cotton clothesline into the cylinder as you can, rotate up toward TDC and compress the line. Service stemseals. Remove rope, do next cyl.

Ah now you are bringing back memories! I used to do that before I had a compressor.

I doubt BMW techs would have greasy clothes line in their tool boxes :-)

Think white/bluish smoke on start up

Hey guys,

Just thought I would confirm before we launched into fixing Valve Stem Seals via the AGA tool on a N62tu.

My car with 110000kms only blows (large amounts) of thick white/blue smoke on start up. It does this 4/5 times the car is started, and it doesnt matter if it has been sitting for 5 min or overnight.

The plum of smoke is the same as the videos I have watched of other n62tu's with the valve stem problem - but they have the smoke after IDLE. We do not have any problems with smoke after idle.

Any thoughts?

Thanks in advance

Haha. I have done it that way more than once.

Also remember putting a piece of oil soaked leather belt in place of a spun main bearing to make a last run for the finals. (And using a tie wrap to hold up my pants.) Believe it or not, the car got down the track and we drove it home front the track.

I plan on dropping the engine out early next year.
Only planning on doing valve seals and all external seals and gaskets, no head job intended for now.

Thanks for the pics.

I am looking at taking engine out to do the valve seals (using AGA Tool) because we have some pretty major looking external oil leaks - so fix them all at once...

Any one have a times guide for taking out engine in an E70 x5?
