We did an E46 328i head gasket back in the spring, double VANOS engine, the OEM service literature was overly complex and the only speshul tool you actually needed was compressed air. Fired right up and ran great, come to find out most BMW experts sell an engine swap as it's "impossible" to reclock the VANOS shit.
What are you trying to do? I may have a manual around somewhere, I remmber it being a PITA to find.
doin that. oem service manual is overly complex, bentley is good. probly not experts if they say its impossible but ya you need some special tools to lock the cams and compressed air to apply pressure to the oil fitting for vanos. you guys make somethin to pressureize the vanos?
some "experts" will sell a swap because if it was overheated enough it weakens the threads in the aluminum block and they pull out when re torque the head down. then you have to timecert it or some shit
so pretty much you want to loosen and retorque before you bother pulling the shit, which i did last night, round 3 of tightening and the center stud got too easy to turn
didnt have much hope for this motor anyways considering a swaping in a 330/x3 motor now
what id like to do is throw in a iron block single vanos motor from the e36 but from my searching i would probly be the 1st to attempt it convert to obd1 for boost probly have to keep the stock siemens dme or nothining would work and run a obd1 dme
fuck if i had the time id do some rhmt shit
fuck bmws
