Short update!

Spent all weekend taking the motor apart...I need to order more gaskets, I thought I had everything :(

Onto the pics!

Where it happens baby!!



Tranny (guess which is one is which)



On the stand:



Valve Cover off:



Block:



Head off:



Block:



So I have a 3.25 LSD that I'm picking up this weekend and I will hopefully put the motor back together over the weekend as well.

I have almost everything I need to get the swap going :)

So I've been slowing degreasing the accessories, nuts and bolts.

I've been using the Simple Green car wash green gooey stuff and it works better than the degreaser!

I threw all of small shit in a bucket full of mineral spirits, I hope the stuff will clean up well..

Any recommendations on how to clean the block and prep it for high temp paint, what about the accessories?

[iwantspeed]

looks great

[dude8383]

Thanks man!

Anyone care to chime in about the cleaning bit?

[FredK]

Well, cover up the top of the engine so crap doesn't get in. :D

I've painted a couple of engines so far and I've just used a scraper to dislodge the heaviest buildup of crud, then a steel brush and engine degreaser to remove the remaining oils. Finally a washdown with some brake parts cleaner, and then you're ready for paint.

How do I protect the piston's and the cylinder walls from any over spray?

I was thinking some saran wrap and painters tape.

Yes indeed! I've been thinking about it for the longest time. Finally I'm there but I've got a long road ahead of me!

I just found out that the build up of crud around the cylinders is due to the motor burning oil! Now I have to pretty much do a full rebuild - not something I had planned on doing!!!!

I'm pretty pissed, but also happy that the motor is still on an engine stand....BUT I'm still pissed that I have drop a shit load more money into this :(

Yes you are =) That is Sam's 318i sedan. No work has begun on the dschwarz car because he still drives it!

Short update dudes:

Took apart the block completely...didn't bother with the plastigage just yet because I'm getting some M52 bits instead :D

M52 crank, M52 rods, M52 pistons!! MOO POWA!!! Well torque...

Anyways, on to the pics:











I was thinking about getting the block hot tanked...What is the approx cost for this?

[FredK]

At my local machine shop, it's $60 to get a block hot tanked, $20 per cylinder to hone.

Sweet, good to know!

I'm going to hone it myself :)

doesnt it have to bored for the M52 pistons?

Woah, did not see your post.

Nope, bore is actually the same @ 84mm.



Small update:

Finally dropped of the block and M52 crank at the machine shop.

Bought this:

pricing is pretty good :)

i was going to get wiseco pistons but didn't like the idea of proprietary rings.

came out to $655 shipped!

Stay tuned :)

This thread is going to really start moving in a month or so.

Excuse my ignorance, but what does "2nd oversize" for the pistons mean? (From the BMR parts description)
Cool project. I hope it comes together well for you. I hate those hidden costs... the ones that don't show up until you take something apart.

I believe that this is the next measurement in line after the standard bore size.
