6&7-Bolt 4g63 Front Case & Oil Pump Rebuild
Here we disassemble, clean, inspect and rebuild both popular 4g63 front cases. This is not difficult, you just need to know what to look for. Something else that happens in this video is the analysis of one of the factors that caused my 7-bolt engine to fail. It wasn't the only cause, and we'll talk about that later, but left to its own devices and without the other contributing factors, it would have been the only cause.
4g63 Block Oil Gallery Mod
This modification is intended to improve your 4g series engine's oil delivery. People frequently discover large chunks of flash in their engine's main oil gallery. It's because the galleries are part of the cast, they're not machined into the block. There is also a very rough sharp edge where the main oil gallery is bored into the block, and oil must make a slightly greater-than 90° turn in order to begin its course to the parts it lubricates. Both of these conditions cause turbulence in the oil flow. My goal in this video is to eliminate as much of that as I can. This is a cheap and easy modification if you have the tools, and the patience. Any engine with cast-in oil galleries could probably benefit from this. Be careful not to cut into the high pressure oil gallery or else you will circulate un-filtered oil to the #1 main, oil pump, and rear balance shaft. You will also deprive the rest of the engine the oil pressure it needs to operate. So in short, punch a hole in that and it's trash. I did this my way, everyone may choose to do this a different way. I just wanted to make this video to raise awareness. Also, there's a great thread on DSMtuners about this. Pictures and everything. Written by a machinist and friend of the DSM community. Go give him some reps because he's posted a lot of great info about the DSM oil system over the years. http://www.dsmtuners.com/forums/articles-engine-fuel/452546-4g63-block-oili ng-mod.html
