2007年7月19日 · Hey guys, i'm shopping for an M42 318, and i've seen some for very good prices, but they have high miles, as in 200-230k. The owners say they've replaced a lot of stuff, like water/fuel pumps, t-stats, radiators, etc, all that preventive maintenance goodness.

2025年1月17日 · SPECIFY FULL ENGINE DETAILS IN “SPECIFICATIONS” SECTION DURING TUNE CONFIGURATION! A popular request by people with one of MetricMechanic’s wonderful 1.9, 2.0, or 2.1 L M42 engines. This tune is intended specifically for the MetricMechanic (Metric Mechanic; MM) upgraded M42 engines.

Release the timing chain tensioner so the system is under tension and then get things lined up (or have someone press on the timing rail to put some tension in the chain). From there get the sprockets lined up, and on a stock motor the bolts should be centered in the slots. Tighten it all down and turn the engine 3-4 times by hand via the crank ...

2018年11月3日 · The M44 timing case has one major difference from the M42 timing case. It does not have the mounting bracket for the crank position sensor, so you would need a custom machined bracket for that, and it would need to be properly designed to ensure correct ignition timing. You can use the timing case from a 1994-1995 M42 engine without this issue, and it uses the plastic guide rail instead of the ...

2018年7月22日 · 7 times out of 10 on an M42 it's a cracked head between a valve seat and a coolant passage, usually cylinders 2 or 3. Either way you're stripping the engine down, so you might as well get started. In my experience a head swap with engine in place isn't a big deal, but if you want to spend the extra and rebuild now is the time.

2016年11月14日 · Ok, by mi primordial calculations with M47 crank, M50 rods (135mm) ant oem m42 pistons we have 1950cc and something around 8,4-8,6:1 . Good. Also it's possible to put the M54B30 pistons to the stock M42 engine, and will have similar CR numbers (8,4-8,6). My question is if they're strong enough because they have less metal from the top to the first ring. M50 pistons are out of play, to much ...

2016年11月14日 · The M42 has the same bolt pattern as the M50. Therefore, you may use any number of different transmissions, such as a Getrag 250 from an E36, ZF 310, ZF 320 (E36 M3, E36 328i), and newer 6 speed transmissions.

2014年5月6日 · Hi everyone, I own a 1976 BMW 2002 and I'm thinking about swapping in an M42. I was wondering what kind of performance upgrades I could do to the engine to get a little more power out of it; I'm looking for about 145-150 at the flywheel. Any and all suggestions are welcome. Thanks!

2018年10月4日 · I have owned a '92 318i vert since 1999, and religiously used conventional oil in its M42 engine until a certain BMW parts warehouse advised that Red Line synthetic 15W50 would be a better alternative. I have been using it for several years with no problems, but my BMW-certified mechanic advised against it. Now I'm both confused and concerned, given his adamant response, and that he used to ...
