Thumbs down Leak Down Test

Well, what I have feared most has happened. My new to me 95 325i has a leaky head gasket. My local BMW dealership did a leak down test and confirmed it positive leaking into the coolant. Which is why I've been overheating, and the white smoke following me. What I would like to ask all of you here is - what next? Should I sell it and take my losses? Should I buy a used/rebuilt engine and replace it? If yes then ebay? or where? I really dont have the funds to do to much here, which is why I bought a 95 not a
2005.
Still, I'm very disappointed I had some dreams for my first bimmer.

I forgot to mention, the bottom end wasn't very good either, bad compression, so I'm not considering a head job. The mechanic told me the head could even be cracked.

A bad head gasket will mess up your compression readings so I wouldn't automatically junk the engine.

Really depends on your finances and how much you love the car.

Me, I'd do the headgasket job. But I'm not you.

I agree with BMWJNKY, try another compression test after fixing your headgasket. The headgasket you can do yourself, just have a machine shop check your head while you have it off.
good luck!

Good points guys, but I had to drive this car home because I wasnt going to do anything at the stealership. It was overheating pretty bad, not smart I know. So I'm afraid I may of warped the head or caused extra damage from the heat. I think I'm going to do an engine swap. My engine has a ton of miles so any engine will be an improvement from mine. Any experienced swappers have any tips? I work with a guy who has done quite a few swaps, but not on a bimmer. Thanks for your input.

I've spent the whole night searching on the net, havent slept in like 30 hours. Anyways I have found a replacement engine for $800. It has 146,000 miles - half of what mine had. I've never replaced an engine, but like I said a guy from work has done some on non-BMW's. Going to put on the aluminum
t-stat housing this time while I have it off from Bavarian. I'm sick of these cooling system problems, seems pretty common to E36's.
Later all. Wish me luck.

Good luck...

Are you swapping for the same model motor? It would be the easiest...

1997 E36 M3 - running stocker style right now...
