My experience after spinning a bearing - Toyota GR86, 86, FR-S and Subaru BRZ Forum & Owners Community

TEWwild · 08-16-2017, 03:52 PM

Short version, spun bearing, decided to go used while rebuilding....been a long 3 weeks without my car but she is finally back on the road. Thought I would share the experience so others may learn from my mistakes

For the full version, see attached PDF.

Keep in mind there are 2 things I had never done before, swapped a motor in an FRS or rebuilt any motor.....I have now, twice for the swap, and will be twice for the rebuild

All questions or comments welcomed!!! Enjoy the read

Great write-up and documentation of your experience and thought process. Sucks it happened though.

Very nicely done! Both the work and the write up.
Refreshing to have somebody break something, fix it and carry on with no whining, complaining or blame seeking.

Sucks to hear man, what the hell happened?

Kudos for taking on the motor swap/rebuild!

this is a really good advice lol.

Great writeup, except for most people I would recommend a leakdown test instead of compression test as it helps to better diagnose source(s) of leaks in an engine, especially one that is out of a car.

Considering you've never been into an engine, your progress is nothing short of amazing. Congratulations and good wishes.

What caused the loss of oil? Just too many track sessions without checking/topping off?

Hate to admit, but yeah, hadn't checked it in a while... Thought about it on the way but once I got there, just changed tires and hit the track. 4 laps in, noticed a loss of power then heard the dreaded rod knock. Wasn't sure of the source so took a cool down lap, 3/4 of the way around, stalled when downshifting......Had it pulled into the garage to cool down. Started once after cool down, heard the knock for sure and shut her down.....

Good job, young man ......

I like your lessons learned ......

Some day, you will be able to tell that story as a back-in-the-day story.

However, since you already showed pictures of your garage, you won't be able to tell folks that you did that engine rebuild, in a drafty barn, during the winter, in subfreezing temperatures, working on a dirt floor, using only a monkey wrench and a screwdriver, working at night and seeing only with a coal oil lantern.
