Exhaust Valve Stem Seals Leaking Oil
Hi everyone,
Like the title states, the #3 cylinder (passenger side rear) exhaust valve stem seals allowed oil to leak into my exhaust system creating a ton of smoke when the car was under load and accelerating from a stop. At the time the problem began, mods included a JDL turbo kit, Verus AOS, and a JDL oil cooler. I was speaking in past tense because my engine is now getting built with forged bottom end components and Supertech valve springs since the engine needed to be removed in order to fix the valve stem seal leak anyway. I’m also changing the AOS to Radium’s dual catch can. The reason for this post is because the mechanic that’s doing the engine work stated that he believes it’s a common issue with the FA20 motors. He said that a WRX came into his shop with the same issue... Has anyone else had this problem? This rebuild has obviously taken a hit to my wallet and a little worried that the problem will surface again in the future..Any responses are greatly appreciated! |

Exhaust Valve Stem Seals Leaking Oil
Yeah I haven’t seen anything either but wanted to throw the question out to the community anyway...
Does anyone know what usually causes valve stem seals to go bad in the first place? Sent from my iPhone using Tapatalk Last edited by kimcheefists; 03-07-2019 at 05:07 AM. |

Usually with high mileage 5SFE had that issue. Certainly not a very common problem with toyota engines.
