Im very impressed. Some serious skill and patience!!!
I just finished 2 weeks ago the timing guides on my 177k miles m62tu 7..I timed it with the special timing blocks and volt meter...No codes and running beautifully. I spent my 2 week vacation on her..total 49 hours ...all taking it slow and cleaning as I went along

This has been a long time coming. Last night i replaced the oil pump chain as well. Figured dont want to go back in for this either. While I had the engine turned over in the stand. I took my pick and cleaned out the oil screen on the pump. pulled pieces of the guide rail out of there.. glad i got that crap out, as im sure some of that was restricting oil flow. Originally my biggest fear was doing the timing, but i found a site that has the bmw workshop manuals for free. Cant download so needless to say, laptop is in garage with me at all times... heres the link in case anyone needs it, http://bmw.workshop-manuals.com/..

Now I just worry about the head gaskets. I did everything according to spec. Cleaning and what not. Just dont want to have an issue with these puppies. Not that it would be hard to get to with the engine in the car. its just alot of work..

I have alot of hours in this project already. But Im hoping in the end, it will all be worth the time and effort. oh yeah and money spent on her. She is a tinker toy mainly for me, but i love love driving this car. Timeless look, great ride. And even after 16 years still turns heads occasionally.

And who can resist the awesome analog car phone in the console. Once in a while i would hold it up while driving as if talking on it, just because. LOL...Not that it works...But just wanted to do it. LOL

todays agenda.
Engine onto hoist.
rear seals replaced,
upper oil pan gasket replaced,
flywheel back on
torque down guide rails and oil pump nut
and timing chains installed

heres to being up nice and early today...

will post pics later of the progress...

BTW FABOCH,,,, i love those rims...very classy looking.. And the dark stitching on the interior... Once i have everything running mechanically, i want to get the seat covers redone.. Two tone grey with black center on them..I think it would look really nice..

Re: Mission accomplished

Well nothing apparently can be easy..got the upper oil pan off..that was easy..got the rear main seal off.that was easy..but the bolts holding the cover on that keeps coolant in..well not so easy.4 of the bolts were coroded and even with soaking with pb blaster and a small amount of heat to the block. The heads of the bolt busted off..drilled one out..looks like ill be rethreading a few wholes though...

Re: Mission accomplished

View of the crankcase...

Rear cranshaft seal was really brittle..glad i pulled that off and will replace

Upper oil pan gasket is useless..bottom right corner looks like possible area for leak..that gets replaced as well..

I hear timing a non vanos M62 engine is easy...You should see the steps for the M62tu

u need 2 people to do this...WHile 1 is holding donw the cams with 27mm open wrench u can loosen and then tight the cams with the T-55 torx head...I used a 3/4" drive torque wrench , using a 3/4' to 1/2" mini ext to fit the t-55 torx bit..cause the 81 ft lbs of torque is difficult to manuever.....Even if the blocks (homemade) move u can reset the Blocks on the cams without having to redo the process...Just have your helper HOLD not counter hold the cams as you loosen or tighten

Okay. So now i have a question.

Being 4 of the bolt heads broke off due to corrosion over 16 years when removing the rear coolant cover to change the gasket. And having to drill out the busted bolts. One of which walked off the bolt head and well, you can figure out the rest.

I was going to have a welder come to the house and fill the wholes, but only if they can be drilled and tapped...

But in looking at this pic below. Why in the world is this cover even there to be removed. Why is this not, well welded to the block. I mean in looking at it, all it appears to do is stop the coolant from pouring out...

I guess my question is, why couldnt I have the cover welded to the block, as opposed to screwed to the block.. Might sound like an idiotic question, but i cant come up with a logical or mechanical reason why it is bolted on in the first place..Just seems like a potential issue in the future...

Am I an idiot for thinking this..

Looking to you members to offer some reason why i cant have the cover welded to to the block and not ever have to worry about a potential coolant leak in the future...

My "guess" would be for the purpose of temperature variations and the need to flex without getting metal fatigue. The bolt-in with gasket would be more forgiving than a welded plate.

Just spoke with a mobile welding guy. In reference to my bolt whole issue for the coolant cover on the back of the block.

He said he can plug weld those wholes,but drilling and tapping will be tough. It can be done, but he recommended trying the helicoils first. Said if that doesnt work out, he'll come and make it right.
Also asked him about welding the cover on instead of bolts. He informed the reason is because of thermal expansion of the engine. that there is a chance the weld would crack as the engine heats and cools heats and cools. So that is out...

Well, onto trying the helicoils and we'll see what happens....

New power steering lines and orings arrived today. I guess I know what ill be doing this weekend. Will be easier to change all these out with the engine out of the car. Going to degrease the engine bay as well. I cant stand the 16 years of grime and grease in there. Waiting on new studs and copper nuts for the exhaust. If weather cooperates, exhaust gets painted black with high temp paint... More for me then anything.

Also ordered the Helicoil kit from NAPA. That is ready for pickup today. So now i can see if this works on the rear coolant cover bolts that busted off.

Updates and pics to come this weekend.....

so i think ive found my answer, in looking at the attached pic from German Auto Solutions, it looks as though my oil lines are reveresed. They appear to be correct to the block, however they are reveresed on the oil cannister, Which is bizzare, because i never disconnected them from the oil can, just the block... Interesting

any thoughts on this one...
