SOLVED Body: '98 OBW Current motor: EJ251 block, EJ25D heads (rings are letting oil be consumed, and there are sounds of the beginnings of rod-knock) Newer motor: Reman EJ253/251 block, EJ25D heads. Hey folks. I bought a reman block form subaru. EJ253/251 block for a 2003 forester. Mating it with EJ25D heads to replace my current hybrid (EJ251 and EJ25D heads). Everything is just about ready to go except the PCV system. The newer block has what appears to be a threaded-in bung to accepted a threaded PCV. Being that the intake I'm using is for the heads, it already has a PCV. Has anyone put a newer block into an older system and routed the PCV system successfully? The old-style is just a pipe that comes out of the block, with the vinyl tubes coming off of it. They don't fit over the new interface. I'll try and get photos soon. Looking at pictures for the newer PCV, it doesn't look as if its outer diameter is the same inner diameter of the older crankcase hose that would be going up to the PCV on the intake. a Thoughts and advice much appreciated.

The engines on my 84 gl 4wd wagon, and my ‘85 Brat look pretty much the same. Are the exhaust systems the same?
Attention all turbocharged EA owners! This thread is to gauge the interest in an aftermarket replacement for your MAF-to-turbo hose. As you probably have experienced owning an older Subaru, many critical parts are no longer available (NLA), including the inlet hose on our EA81T and EA82T engines. This particular rubber hose happens to be out of production and is installed in a location that sees a lot of heat. I found the pipe on my personal vehicle had split where it joins the turbocharger's inlet and once I found out I couldn't order a replacement, I reached out to a few companies about building a replacement. The details: Replacement hose made from silicone Molded to match the contours of the OEM part Nylon reinforced for rigidity Lined with fluorosilicone to resist damage from PCV oil mist Resists degradation in temperatures up to ~500*F (EPDM rubber is good to ~210*F) CARB legal There is also an opportunity to have replacements made for all the other molded rubber PCV/vacuum hoses that are currently out of production. At this point I have a rough idea of what it will take to manufacture this part. Price will depend on how many parts are made, so this thread is for me to get an idea of how many folks here would be interested in one of these hoses. There are still a lot of variables to work out, but I'm open to comments and suggestions. So, who's interested?
