I really don't look forward to rebuilding all these seals though. They are everywhere. Both pans, the timing cover and the valve covers. Not even sure how many tubes of 3bond I'm going to need. It also wants 3mm width here and 4mm width there but only 2.5 here. I'm going to need a bunch of tips cut to various sizes to build these seal to spec. I am curious, when you tore yours down, what rod was snapped? How did the other bearings look? Did you find any blockage anywhere? I saw in another thread that you changed your oil before and after a track day so I know your oil level was good. Any idea what your oil temps were when you threw the rod? Do you have a pressure gauge, if so, what was your pressure looking like around the time it threw? |

At some point I plan to connect the RPi to the reverse camera input on the head unit. Then I can rewire the reverse wire to my RPi so I can trigger the input to switch to the RPi whenever there is something urgent to display. Until then I will just strobe the oil dummy light when the oil pressure isn't right. |

In the future I want to use it for data logging and then automatically sync the data when I get to the office or my house so I don't have to move an SD card back and forth (Tactrix). |

Interesting reading here. I’m in the process of rebuilding a motor I blew a few years ago. I have a new short block that I’m gonna toss some Manley rods in. Found a used head to replace my damaged one. Got some Kelford valve springs to toss in them. It was turbo’d when it blew. I was thinking I floated the valves on my 06/2012 motor. After reading this though I’m gonna check out the bearings in the damaged block. See if any of them spun and what kind of wear they had. Something I’ve been curious about. Just haven’t taken the time to inspect. I’ll post up my findings.

I spun a bearing in a 2013 only 120k km. Car had been tracked but modern engines should not be spinning bearings. It is an automatic NA and I have broken two factory flywheels. Once with the old engine and now with the repalcement?

You have a good point in people listing oil related problems. If the FRS/86 is killing bearings in numerous cases on stock and modded this is something that seriously needs to be addressed and not with Toyota just fixing it when it happens. From what I’m reading in various posts and forums, it appears as though the FA20 engine has a major flaw. Either port clogging, oil too thin because it runs too hot or whatever. An engine especially stock shouldn’t be crapping out after a few spirited jaunts. I’m thinking a major recall or buyback for the obvious issue. Granted it is a sports car but it should be built to at least be reliable beyond 100k especially if stock. Just my thoughts on it.

Forced Induction. Like a supercharger or turbo.
