+1 if you can't find the problem now, or the crack then filling it up with water wont do it as the crack will only open with heat and presure. you can get this tested by a machine shop but the block needs to be bare i THINK. you should check tho..

+2. I'm all for saving money and having the pride of doing it yourself, but sometimes it's best to have a professional do it so you can be sure the job's done right.

Well if i let it sit for a few days then something might happen. beats stripping taking the engine out and stripping it down

i know it sounds like overkill, but how much does it cost to buy an m42 engine over there? here its so cheap that if you're having serious problems like that you'd be better served to find a good e36 complete engine and put it in. you can then sell on all your bits if required etc.

I wouldn't bet upon that stuff, but I'd follow the tried and true method. Never know if the tape is leaking and such

When I first got my car I was horrified at the big globs of RTV at the timing case/ block interface. I eventually learned of the infamous profile gasket issue. BMW issued a tech bullitin that said, in effect, "use tons of sealing adhesive when installing a profile gasket." I'm pretty sure my car was dealer maintained before I got it, and I think what I didn't like was actually the way it was supposed to be. I would suspect the profile gassket sealing before cracks in the block. Try to find the service instruction. I think I learned about it on bimmerdiy...

well the techs at the shop i work at said they cant think of what i could have done wrong. I guess tmr I may put it back together again. I have gotten the block very clean and now have bmw brand head and profile gaskets. I will use sealer on the profile too. any tips or anything?

and is this all right?

put gasket on
put profile gasket on
put head on and make sure its seated
put bolts in finger tight
torque in the order in the bentley to 22lbs
turn all 90 degrees
turn all 90 degrees agian

Just curious. How did you make uot the 2nd time on this? If you were to ask me, I think the previous replies made sense to me about the profile gasket. Also the 3 way joints in the timing chain cover need some sealant, too. Anyway, give us an update if you have one. And don't worry about not getting it perfect the first time.
