To be frank, I probably didn’t need to go this far. However, every time I put a brush or swab down into the oil galleries they continued to come back dirty so I went ahead and pulled only the plugs necessary for oil cleaning, as well as the two other small ones at the rear…
Category: Engine – Oil System

Some love for the Subaru too! A proper oil change!
Murbella didn’t get all of my attention today. I spent about 30 minutes on the Subaru Forester. Now I have a lot of the oil burning issues that plague can plague these cars. In fact, I often consume quite a bit of oil during normal operation and also get awful fuel economy on this vehicle….

AH Engine – Last Minute Case Prep
So the trials and tribulations of find local AN fittings that will fit without too much case modding proved not to be. Even with some other people’s photos of their layouts, all of the similar 90° fittings I could find had “nuts” that were just too thick, taking a massive chunk out of the pulley…

AH Engine – New direction in plugs!
So the EMPI oil gallery plugs you can buy suck balls. I didn’t expect something as simple as these to suck the amount of balls they do but it is big balls and those are well sucked by these. Yes, the VW Type 1 case is relatively soft compared to many other engine cases. And…

My Basic Full Flow Filtration Plan
So once I pulled the oil gallery plugs on the case, I was more or less committed to at least ensuring the case was truly clean and of course, having to tap and plug them again. I was back and forth in terms of just putting the plugs back in for this rebuild, but the…

The Air-Cooled VW Engine Oil System
The oil system in a VW engine is, like any vehicle’s engine, crucial to proper operation. The oil system of the air-cooled VW flat-four engine is even more important than one might realize since along with the primary lubrication function, the oil also serves a critical cooling purpose, with some of the oil being directed…

The negative effects of poor oil maintenance!
Technically, once a previously used VW air-cooled engine block is deemed to be crack-free and adequate to be rebuilt, and if the bearing saddles and thrust are sound and not in need of further machining such as an align bore, the block can be rebuilt as-is and should be sound for quite some time. However,…
I think I may be ready to drill and tap tomorrow.
I realized that I was missing some tools to complete the block preparations so I ordered them yesterday and hopefully they should all be here tomorrow. I picked up the 9/16″ drill bit to do the main oil return line and and I’m hoping, based on what I’ve already seen, that I probably will not…
