Op also check your belt tensioner is not too close to harmonic damper...it tends to bend over time and could suck belt into crank seal....worth it to do this while you at OFHG and you can also clean up built up crud while its all apart.

I agree, DIY since you have been wrenching some. Use a long weekend and get a rental car if necessary. Save the money for the oil pan gasket or other things.
For my non-turbo I used a new URO valve cover. That is what I would suggest. If you are getting smoke on start up like I did, it is probably not the oil pan gasket leaking. Mine was the the valvetronic gasket AND somewhere from the valve cover. I did not see a crack, but while not as bad as the valvetronic leak, some oil was still coming out from the top side. New Uro cover solved it. https://www.e90post.com/forums/showp...6&postcount=16 Like others said, drive belt and tensioner while doing the filter housing gasket. Quote:

Several months ago, the belt frayed and wrapped itself around the crank, though the indy shop said it did not penetrate the front main seal. Dealer did not identify that seal as a possible leak source, so I'm assuming that it's ok. The repair bill on that was the $1100 I mentioned in a previous post - new tensioner, belts, and something else I forget at the moment. I think the harmonic balancer was ok, but I don't recall if they said anything about the tensioner being bent too close.
Question: would any of these leaks or possible leaking points cause the engine to misfire at idle? The idle is normally 650rpms, but since it has been idling with an occasional sputter, rpms settle at about 750'ish. When I took the car out for a test drive BEFORE putting in a set of high output coil packs (BavAuto/ECS) and factory bosch plugs (4 prongs), the tuning app, MHD, showed the cyl 1 timing correction going bonkers when maintaining speed in any gear, but was normal when accelerating or decelerating. No error codes to work with to find out more. AFTER putting in the high output coil packs, the misfires continue, but the cyl 1 timing correction was no longer going bonkers. When I put in the new plugs and coil packs, I did not see any oil accumulation around the plug holes. The color of the old plugs looked ok - no oily plugs or evidence of fouling that I could see. Sorry for being so wordy - just trying to be a bit more precise for clarity. Btw, thank you, everyone, for contributing so much information and experience. That kind of participation is what makes this forum an amazing resource for all. You guys are the best. Last edited by trading10; 05-25-2019 at 02:26 AM.. |

At least do the tip of the engine yourself. That job is easy, just takes a bit to remove the stuff above it. |

Honestly the reason I havent bought one is because my E90 has been to reliable to justify it. I guess it would be nice for oil/coolant/brake change as well but even those Im not having to do too often. Quote:

But seriously though to the OP, Ive got probably $4000 in tools I have collected over the past couple of decades working on the cars/motorcycles but have likely saved 20k+ in doing the work (probably 30k if I really researched on the motorcycles). And once you buy the tool you have the tool, so its free next time. Plus you get the know that YOU did it right, not some idiot kid at the dealership or oil change place. |

I would have looked at the SA and said, it's nice to want things. Other than the Oil Pan Gasket, the cost of DIY is about 5% of that quote.

1) Rear Main Seal 2) Turbos 3) Oil Pan Gasket I've done the oil pan gasket on jack stands; it's doable that way. Turbos I could see being done on jack stands, but I don't imagine it would a whole lot of fun. The rear main? I'm not sure it could be done on jack stands. Maybe? |

forklift jack stands like these?
https://www.homedepot.com/p/Omega-7-...075B/206524689 A lift would be great of course. Always wanted one for previous project cars. Repair costs in the last few months total about $3000, so I've been bleeding too much cash to get one. Bitcoin is on the rise again, so maybe I'll have enough profit to afford a basic lift. Getting the car off the ground beyond 3 feet would be nice, but then we're talking about a two post lift for 2-3x the cost. |
