Cylinder heads and cams are at the shop. Looking forward to seeing the finished product hopefully in the next few days.
Saw some of the heads that they had worked on and they look brand new. Not the cleanest or nicest shop ive seen. But hey, who am i to judge.

Piston head cleaning has begun. Started getting the caked on carbon build up off the piston. Very gently....and will thoroughly clean the cylinder walls to make sure i get out any of the gunk that may drop down there, since i am taking the lower oil pan off for cleaning, degreasing and what not, im not overly concerned about contamination or anything of the sort, as ill clean it all up...

Heres to good times... ill post pics of the piston heads and cylinder heads once i have them back...

Time to order up some parts for this beast....

Any thoughts from the forum on possibly pulling the pistons out and doing the rings?

I dont ever recall have smoke from the tail pipes during driving or anything of that nature. Car has 185K miles on it and since i have had it, has never really been driven hard. Once in a while a good stomp on her just for fun, but for the most part she is a highway driven car for the last 15 to 20K miles.

Thoughts and comments on it are appreciated...

Sounds like everything is going well. Of course, I'm not the one having to turn the wrenches on this major project. I do know the results will be your reward. Thanks for continuing to share the project.

Having it that far apart. YES! Do the rings while its down. If it were me, Id get some 4.6 pistons or some .10 to .20 over pistons and have the block machined and cross hatched with all new crank and rod bearings. If you dont want to go that far, then at least new crank and rod bearings with new rings and take the block to your shop for a nice cross hatch and hone. I would even mic the crank and if all is well Id do a nice crank polish (free HP).

If you really want to get crazy put some 4.6 pistons (think you can get 4.6 piston kit for about $800, and throw an S62 (E39 M5 crank machining required) and a re-map by VAC motorsports. You'll have a 4.9ish liter with about 400ish HP.

Spoke with the gents from the shop doing the valve job, decking and cleaning up of the gunk build up. Should have them back next thursday or friday. So in the mean time started cleaning up the block with some degreaser and a nylon bristle brush and a scraper. Needless to say, im sure this beast was running hotter than normal just from the thickness of the gunk build up on the upper oil pan and around the outside of the block itself. I dont think this engine has been degreased or cleaned in the life of the car. Hell some of this build up might have been plugging up some more leaks i didnt know about. LOL.
I had no clue this engine was a silver color. I thought it was just a black sludge looking color out of the factory. LOL... after some degreaser and scrubbing and lots of shop rags, one side is nice and cleaned up. onto the other side. and then a final wipe down of this animal..

parts list together and will be ordered in the next day or so.

It will take weeks to wipe the smile off your face knowing you have a new motor!
The psychological value is priceless!

The car will drive smoother, the acceleration stronger, and your chubby bigger!

all of those factors are already kicking in. Its nice to see the engine block cleaned up.. Lower oil pan will come off for a new gasket and what not. but i can already feel the anticipation of this thing going back together.
Gotta put the tranny in the back of the truck and take it to a welder to have one of the mounting points welded. It cracked when it fell off the jack when removing from the engine. But thats okay, ive been told shouldnt be an issue.

more pics to come when i start putting her back together. Just looking forward to getting her back in the car and looking down and seeing a clean engine, not a black grimey thing that you cant see.

and of course, the first turn of the key and hearing her start up again...at that point, ill have that massive smile on my face..

Ill say it again ou18. If youv got it torn down that far, at minimum you should replace rings with a crass hatch from a machine shop. Get the block hot tanked. And replace crank and rod bearings. Then it will be a new motor ready for another 200,000+ miles.

I would just hate to see you spend that money and do all that work just to have to take it all apart again in another 50K miles. Yes Iv seen these cars goto 300,000 miles but they are ready for a full overhaul at that point. Why not just go the extra mile and take care of everything now while its apart.

Only you know your budget though. Thats just my opinion looking from the outside in.

Good luck and hope everything works out for you.

Latest update...

Went to the local indy shop here that specializes in BMW/MERC/ROLLS ROYCE/BENTLEY and JAGs.. Ive taken the BMW in there a few times, and the owner of our company also brings his high end cars to them for work as well. Showed him the pics of the engine block. Then asked him about doing the rings, bearings etc etc. Bottom End rebuild.
His exact words... DONT TOUCH IT. He said it could be done, but he doesnt recommend it at all. .. He gave a bunch of reasons to not do it, which all made sense. These guys are the premier shop in West Palm for these cars. So on that note, I think im going to heed his advice and let it ride.

On another note, he told me to send him my parts list and he'll give me a discount and, wait for it, wait for it, he'll let me borrow their timing tools they use to get it timed out perfectly....Needless to say, ill throw some extra cash to him for allowing me to use his tools. Cause he sure as hell didnt have to offer that. He knows the car is a tinker toy for me. So he understands me wanting to do it myself and get the knowledge. Also told me he would print out all the TIS stuff for setting timing and other things he thinks i might need.

So, that is the news on this project so far. Heads should be getting worked today and tommorow based on the schedule the shop i took them to gave me. So probably will be ready some time early next week..

Not much else to report on this front. Im thinking of putting new sleeves around the wiring that is subject to heat as i saw some exposed wires on some of them. Dont want those getting burned thru at any point. So ill work on that for the next few days...

Re: Mission accomplished

Engine block mating surface cleaned up...

See that ring arnd the top of the cylinder wall..how important is that to clean up and get off?

One other thing and stupid question..This is the driver side of the block. Is the cylinder closest in the pic cylinder 5 and furthest is 8 so that would make cylinder 1 on the passenger side opposite cylinder 5?
