That's called a "money shift", and you are just about to find out why it goes by that name.

You've bent valves and likely broken rocker arms. You've dinged the piston tops with the valves, possibly even cracked the head and broken off one or more valves and the pieces are stuck rattling around in the chambers. Perhaps worst of all you kept driving it!

Normally I'd say welcome to the fest, but in your case, I'll say SHAME on you. You aren't the first to do such a thing, you won't be the last, but this is going to be a very expensive lesson for you. Expect at least $1200 in repairs. Almost certainly it will be more than that. Buying a used M50B25 engine (what you just ruined) and swapping it in will be far cheaper than paying for repairs to the damage.

I'm just a grumpy old guy, but I recall what it was like to learn such lessons. I hope you really DO learn from it.

yea. it is easy to find wrecked e36's for less than 1000 now. find one that has millage you are looking for and BUY IT. take what you want from it, and part out the rest. you could make 500 back from the part out easy, scrap the shell for 300, and then essentially be paying $200 for the m50 you need. that is if you have the know-how, room to do it, and time.

Been a long time since i posted but sent the car to a shop to check time it was good,next they did a leakdown test which showed all cylinders north of 175psi. Next theychecked vacuum leaks which every hose had a tear including the intake boot,they also cleaned the iacv...adter that vroom vroom she was alive i drove the car since then till now and now my issue is i ripped 2 mounting holes out of the sunframe so i got the diff and gastank out.waiting on reinforcement plates and powerflex bushings i have got a tastefull list of mods since then to being, tms shorty headers,aa track pipe obxr underdrive pullies, cai,bilstein shocks eiboc springs,strut bar,sparco harness bar, bimmerworld r tabs,crossed and slotted rotors, megan racing lcas ..my wors of advice never give up!!!

Go ahead and add a thermostat, aluminum thermostat housing, water pump and belts to the NEEDED side of that mod list if you have not changed them your self already. When you change them fill it up with strait water and flush the system a few times before you add your 50/50 mix of Antifreeze. ....you will thank me for this when you are NOT sitting along the road with an overheating car lol


if it makes you feel any better my "money shift" was at the drag strip with loud opened pipe on my built n2o vw Golf.....EVERYONE at the track heard it and that was the poor car's last pass ever lol

I think we're all on the same page, but I just want to clarify for others that it should be a 50/50 mix of coolant and distilled water. In other words, don't use tap water in your cooling system.

I've always used tap water, does the distilled water make a difference? I'm one of those people that flush the coolant systems and even brake fluid every other year in all my cars to keep everything it better working order but if distilled water works better I'll switch to it next time

Tap water will leave deposits in the cooling system, distilled water is pure 100% water so it won't. But since you flush it so often you might be fine

Edit: Actually you flushing coolant and brake fluid every other year is what BMW recommends. Eh, just use distilled next time you do a replace it.

With cast iron block and heads you can get away with tap water. With aluminum block and/or head some of the minerals in the tap water make it a viable electrolyte which can encourage galvanic corrosion. If you look at the attached table, the greater the galvanic difference the greater the potential for corrosion, the faster it will occur, and the greater the damage will be. Nickel iron is a common alloy for "iron" engine blocks and you can see from the table it has a galvanic number of approximately -0.1. If you look at aluminum alloys they range from -0.8 to -1.0 and the difference between iron/nickel and aluminum alloys is almost at the two ends of the table.

OP, you are one of the lucky very few that has had a viable motor after a money shift! Glad it worked out!
