I'm building this 2270 and I thought this would be a good one to document. I'm going to try and cover every little aspect of the build, although I'm not necessarily going to break down every process into a step by step.
I'm starting with a 1.7 'W' case. I did a quick line bore check and it's a nice STD case. But more on that later when I actually measure the line bore accurately. Case Preparation - In this section I'm covering all the modifications and inspections to be done on the bare case. Threaded Gallery Plugs, Resurface Oil Filter Mount I used my slide hammer setup to pull the original gallery plugs. I'm just doing the 'normal five'. In this picture also shows the oil filter mount face - I pull the studs and true the surface up to ensure a good, leak-free seal. ![]() HV Oil Pump I have a Schadek oil pump that I've cut in half to mark the case for 'port matching' the oil pump. The ports on the case are smaller than the oil pump, so this simply eases the transition. I use a carbide cutter for aluminum in a pneumatic die grinder to carefully open up the holes. ![]() ![]() Cleaning Stud Threads I chased all the M8x1.25 studs on the case. This eases installation, but also ensures more accurate torque. Any fastener that has a specific torque value should have clean threads. The rust/dirt/sealant/etc on the surface will make the fastener harder to turn, which means you're getting a slightly false torque reading. You'll see the head studs have all been removed. I don't use a tap or die to clean the head stud or the case threads because I've seen this result in loose head studs. I don't touch this parts of the case, and I use a wire wheel on the bench top grinder to clean the threads without risk of removing material. ![]() |

Better clarity about the 'normal five' plugs.
![]() ![]() Here is the section that cracks if you torque the sump plate too much. As I mentioned previously, I don't really consider this a problem since it only ever breaks because of people cranking down on the bolt to try and stop a leak (or just plain overdoing it). Use a sealant on the gaskets and the center nut and tighten lightly. If it leaks, pull it all off, clean up the old sealant and gasket and start over, or look for nicks or a variance between where the two case halves come together. ![]() |

Better clarity about the 'normal five' plugs. Looks like a great build! will be following closely. I'm almost to the point of final cleaning and assembly of my motor (2056). So, my P mechanic, 30 year owner of a highly reputible Porsche only Shop who owns and still races a 914 (along with 4-5 other 930's etc) says that the galley plugs is a waste of time and introduces more problems than it solves...... He insists it is not a case of better safe than sorry it is a case of waste of time and will be sorry. oy veh... (IMG:style_emoticons/default/blink.gif) I'm not wanting to argue or debate, I have NO frame of reference other than the forums and his word, which are obviously in conflict. So, though I know it is fashionable to do this, I'd love to see what peoples experiences are. Who is running their Type 4 (be it in a 914, 912, Bus/Transporter/Bug with and without galley plugs. Has anyone actually blowen one? How deep are the plugs? My apologies if this is thread jacking, so please PM me and not take away from this thread. Bottomline if I do these (I did buy them) I am going to have to find a new mechanic/shop. Took me 6 months to find this guy..... |
