Coolant in oil

Post by adam_torrence » Wed Apr 15, 2020 1:29 am

I recently bout a 1979 528i and did a top end restoration it had a blown head gasket when I took the head off and so I got the head remilled and rebuilt/ pressure tested after putting everything back together it wasn’t running and when I drained the oil allot of coolant was in the pan so I believe my block is cracked :| I will test more tomarrow but now I’m looking for a 3.5 bottom end.

Adam,

Depending on where the crack(s) is/are, you might be able to get it welded and salvage the block.

Please keep us apprised on what happens either way.

If you get lucky you might find an early, possibly Euro, block for a very reasonable price. An easy swap in for a very noticeable improvement in performance.

If you're looking for a 3.5, I'd recommend the e28 b34 block because it's a little thicker and also bolts straight in to your engine mounts. My e34 block cracked between a head bolt hole and the coolant passages and toasted the engine.

I found a 86 635csi that had a rear end collision in a junkyard and got a m30b34 with a 5 speed for 400$ so I will do that swap now. There was a hole when I drilled out the broken coolant drain plug and retapped it I drilled too far and put a pin hole in my crankcase. I will be doing the swap now but I’m not sure what driveshaft fits with the 265 Getrag 5 speed but thank you all for your help
