  1. Kinda was my thought, but I do have the head pulled already so it would be pretty easy to put a new one on.  Any good sources for reman or used heads?  I have bought 2 from clearwater cylinder heads out of California and they do a good job, an m50 head was 850$ 4 years ago and an m20 head was 650$ a few months ago from them.  Does that seem reasonable?

  2. OK so a guy from work picked up a 4/98 e36 sedan for about a grand knowing it had headgasket/head problems.  215k, black/black, AT, pretty good condition for age, a little surface rust but overall good.  He would like to just use it for a daily driver.  Engine ran good before teardown, just intermittent temp spikes from the leakage.  It had been worked on by a mechanic that doesn't know BMW's, replaced a couple hoses, new water pump, thermo, and fan clutch and thought that would fix it.  I told him I would work on it for him, started tearing it down, head has 2 cracks, cyls 2 and 3 from exhaust valve seat to coolant passage.  Cylinder bores look good, no step at the top, no scratches, haven't measured the bore yet bot honing marks are still there.  Problem is that there is a ton of nast in the coolant passages of the block.  Looks like aluminum corrosion that migrated from the head.  My question for you guys is do I just flush out he water jacket on the block as best I can and drop a good head on.  Or find a used running engine and swap in.  I don't think its worth tearing down the bottom end for a full rebuild as the money really starts flowing then.  I don't have a problem with doing the work as I have done a full rebuild on an m50 and m20.  I will get a few pics up so you can see what it looks like tomorrow.  And let this be a warning to everyone, maintain your cooling system!!!  Cracked heads around the exhaust valves are from hotspots due to corrosion buildup in the coolant passages.  Change your coolant to keep its corrosion inhibiting properties good.

  3. I rented a pilot bearing puller from oreillys when I did my clutch and the end was too big to fit into the bearing.  I used a contraption such as yours except just clamped a vise grip on the end of a rod and pounded on that with a hammer.  Also way back you said you needed an m50 starter, I assume you probably have one by now but if not I have an extra that you could save big money on.

  4. Check over your PCV system, I've seen a couple that are super clogged, lines, catch can, etc, mostly from short trips causing condensation buildup.  Clogged PCV will cause higher crankcase pressures which forces oil past seals.

  5. I did some research on this a few weeks back and apparently the annealing that happens to aluminum at even the low temperatures of powder coating can change the strength/brittleness. Especially forged wheels that are relying on the strength of the material vs the amount of material.  I don't think PC on most stock/beefy wheels is much of a problem though. 

  6. I would value that car at about $5000.

    It is a 633 with some fake badging, cheap wheels, crappy Fuzion tires, and nothing entirely special about it. 

    I am only being pessimistic about it because I get the feeling they are trying to fool people into thinking it is a real rare machine. 

     

     

    Its not a Alpina by any means. The only Alpina parts are the gauge cluster face (but not the gauges) and the badges on the rear. Otherwise is a standard 633CSI

     

     

     If the mileage is really that low, Its closer to the $8-10k range, but with its somewhat crappy looking condition $5-7k would be better. E24's do fetch a pretty penny in the right conditions but their asking price reflects that of a B7, not a 633CSI.

     

     

    Good to know guys, thanks!

     

    Glad a real Alpina wasn't treated this badly, it looks rough underneath.
