hi everyone... need help and advice... i have a e46 1999 323i se 4 door.. my engine overheated and poped the head... the cheapest way to fix is to replace engine... now with it been a 1999 model does it have the m52tu engine in or the m54tu engine.. and if it has the m52tu engine in can i drop the m54tu engine in instead.... need help... thanks.. regards alan
How bad is it? Do you really need to replace the engine or just the headgasket? Unless you blew up the engine I don't see why it can't be machined and put back on. Even a used head machined is cheaper then a new engine.
The 99 should have the M54 if I recall correctly. A picture would allow us to tell for sure. But if it is the M52 engine don't waste your money on an M54. Get an S52!
can you tell me what is the s52. as far as know the cost to replace the head gasket and labour cost were a fortune. my engine code is the 256s4.. has no compression on any pots when trying to turn the engine over.. would this s52 fit straight in without any mods done. regards alan
The S52 is the 3.2L engine found in the 1996-1999 E36 M3. It's an OBD-II engine which means its a direct bolt in replacement to the M52 engine. However a new ECU is required. The headgasket is only $100 or so, but it takes about 8-10 hours to complete.
