Engine Swap in progress
Part I:
So, today being bright and sunny outside, I began the attempt at resurrecting my car: First off, the "old" engine is beat. #4 piston is low in the cylinder when it's supposed to be at TDC. I turned the crank by hand (well, by breaker bar) with a rod resting on the piston, and the sucker didn't move at all. Turning the crank back and forth produced a "clinking" sound. Rod is most DEF. busted. What does this mean?? Well, for one, it means the problem was most likely an oil problem. Personally, i think it's most definitely oil. So, I'm ordering an oil pressure gauge to install next week. On to the work: Started out by finding a nice open space to work. Actually, the car was already parked in my uncle's driveway, and since it was nice out and the Beemer was taking up the garage space (stupid pampered germans) I "decided" to work on the car outside while my cousins were washing their cars (and asking me to fix random ricey objects such as busted blue headlight bulbs). Ahh... the great outdoors: ![]() First thing was to remove the hood to get more work space and free lighting. Plus, all the great tuners remove the hood to work on the engine: ![]() Intake piping was removed, and after some discussion with my uncle, he convinced me it'd be easier to remove the engine without the tranny and leave the tranny in the car. To do this, we'd have to slide the engine forward to disconnect it from the tranny, and in order to do so we'd need some space, so I drained the coolant and took out the radiator, fan shroud, and both fans. This sucker needs to be cleaned anyways: ![]() I'm pretty sure there's enough space now: ![]() To lighten the load on the hoist and make things easier, I removed the P/S pump, A/C compressor, and alternator: ![]() ![]() Then I strapped everything to the side and supported them to take the load off the hoses, and get a little space to needlessly remove the brackets: ![]() I also removed the exhaust manifold with the turbo, and disconnected all the harness connections on the intake side and any vacuum hoses coming off the engine. Tomorrow I'll be unbolting the transmission, taking the engine out, swapping some of the intake side sensors (possibly just swapping the plenum and runners as a whole) to convert from OBD II to OBD I, and installing the new engine!!
