My 520iA Road to 528iA '91

Took the oil pan out and found problems... Guess it's time for a new engine.

Got armrests back and they look very nice.

Im looking for e39 528ia to take engine and transmission for this.

Damn...

Bought 5hp18 from e39 and made a deal of m52b28.

Sorry to see the engine issue, but glad to see you are not quitting. Keep going!

I was planning to do swap anyways but not this summer... Did not wanna spend the money yet on engine, but as engine was found localy and cheap I had to buy it.

I found same color trunk lid that looks really nice condition and seller says it's rust free. Very good find for 120bucks.

I will get the engine this weekend.

M52 powered alpina trailer.

Not much have happened. Engine is somewhat stripped down and somewhat clean. Tried to change valve stem seals with compressed air but pretty much all cylinders had one or two valves leaking because of carbon build up. So it was nada. Now engine is at my home garage on engine stand. Gotta try the rope trick for valve stems. And order all the parts to get it ready for the swap.

I'm having hard time finding E38 728i m52 oil dip stick tube which should perfect for this. New one costs a bit too much for my taste.




Back on the road summer 2199?

Been fixing E65 lately. First starter broke down and now electric fan. Without it ac did not work. So money that was itended for this when't in to "dailies"

Ah, the joys of older BMWs...

Well, it has over 400 000km already, so not bad. I also had to replace f10 windshield so more money in to daily cars.

Let's see how it turns out after some wash and polish.

Turned out pretty nice.

Valve stem seals replaced on the B28. Next step is to do the rod bearings. Then put new timing guides in and timing cover with new gaskets back on. Then it is pretty much ready to start swapping the engine as many parts are needed from the old engine so cant really do more for B28.

I will also use cam trays and new lifters from M50. So... let's turn it around.

Opened two rods and looks ok to me for and old engine. Crank also looked good.


Gotta get plastigauge and install new bearings if clearences are ok.

Trying to get this project going this summer. I took out the main bearings from upcoming engine. They look fine apart of two that has some more wear. So new one in order.

Also ordered F30 335i front brakes (someday have to do something about rear brakes too, easiest would be 540i rear brakes but they are hard to find and expensive) and Alpina Classic 18" replica wheels. 235/40R18 front and 265/35R18 rear.

Currently working on my friends E32 750iL to change engine, after that hopefully it's time to do this one.

Test fitted new brakes and it is 10mm spacer all they need to get caliper to be in center with brake disc.

It also seems that you can run 540i brake discs in rear with e8x/e9x (smaller engine versions have 300x20 discs) rear calipers. Bolt holes need minor modification.

You can get those calipers new with carrier for 25bucks, so much much cheaper than E34 540i calipers.

So it will get 300x20 discs rear.

Took out the crank, cleaned everything and put new bearings in. Now I'm waiting for my electric torque wrench to arrive so I can start measuring bearing clearances.



Upper main bearings looked like new, but these are things "while you are in there"

Measured main bearing clearence and all showed the same so all good.

I installed new main bearings with assembly grease. Gotta measure axial play and if it that is with in spec, I can install rod bearings too. I measured them also and all looked good.
