    Ringland failure so now wtf

    in Fourth Generation Legacy (2005 - 2009)

    The part of your car that failed is a ringland, yes? In the combustion chamber of your car, your pistons move up and down to create the "squeeze" in the four stroke "suck, squeeze, bang, blow" of internal combustion. Your piston rings have little lands in them that allow oil to pass through them to lubricate them just enough to not scratch the inside of your engine too badly where they move up and down in the cylinder. There are several of these rings to control oil and compression. The more badly worn these rings are, the worse of a seal against oil getting into your combustion chamber you have, and, consequentially, the worse compression the engine makes. Less compression equates to worse performance from your engine, and after major loss like your car, you consume incredible quantities of oil and lose a lot of performance.

     

    In ringland failure on Subarus, this occurs from lack of oil or detonation. I'd guess that, on your naturally-aspirated car, said piston ring was cracked from oil starvation.

    The longblock and shortblock are two terms you should be familiar with on any car's engine. The shortblock are the pistons, connecting rods/rod bearings, crankshaft, and actual block casing. You can sometimes buy individual components of a shortblock from vendors. You want to replace this entire shortblock given the damage done to the cylinder where your piston ring failed.

     

    A longblock includes the shortblock as well as the heads - the valvetrain components that make up your timing system. On your car you have a single overhead cam. Your head gaskets are commonly prone to failure. You would likely benefit from having a head rebuilding shop resurface your heads to make a proper seal and then put the new multi-layer steel gasket from Subaru on your heads. Your valvetrain components probably don't need much, but a shop can look at your camshafts and tell you if they need replacement. They may, but my Subaru suffered oil starvation and the cams were fine with over 200K on them and are in my new engine. YMMV.

     

    Hope that helps.

     

     

    Yeah seeing as this pandemic-pricing has just raped my asshole dry fist style, i’ll be moving on from subaru. thank you for your help and everyone else on here but **** subaru for continuing having shit motors.
