Valve spring recall can’t start car

Smart. The issues can come thousands of miles later. The more sealant in the oil and the harder you push the car the sooner it's done. When they tore my engine down after it failed there was an absolutely LAUGHABLE amount of sealant in it. Almost like they tried to see how much they could get in there.

My recall was done with the car wearing an UEL, tune and CAI. I even had the Subaru dealer install a set of STi Group N engine and transmission mounts whilst at the garage. No issues, and the car has been running fine with the tune intact.

sigh... I don't know what possessed me to do the recall. Really regretting it now

If you don't need it for registration you should never get it done. The BRZ's have a lot better luck as they have experience with this motor. FRS and you're married to Toyota who, for the most part is very inept

In california I think I needed it to get done for my next registration, but from what I'm reading depending on different DMV's you can get around that.
Getting ready to sell the car once I have it back. Too bad too as I've just finished all modifications I wanted for this car, car only has 25k miles too.
On the bright side, time to shop for a new daily driver. Will probably pick up a AP1 S2000 for modding or a recent year used 86/brz or ND Miata

I thought you lived in Canada?

Not really. This engine is unique to the 86 so Toyota actually has more experience with it than Subaru at this point, since they sold more copies. As mentioned ad nauseum here, the gasket seal is unique to this particular motor. While the recall covered more vehicles in general at Subaru (multiple models) the others all used real gaskets, not sealant.

I completely agree at this point if you haven't had it done, don't do it, but in the end the success of the repair is completely dependent on the care taken by the one mechanic working on the car. It has nothing to do with the logo on their shirt.

The tech at the Subaru dealer where mine was done ruined my motor so no, just because it was done at a Subaru dealer doesn't mean there's a better chance of success.

that sounds realistic. Toyota selling more cars hence the higher recall and failure numbers makes sense. I have no idea why someone hasn’t made a gasket for these yet I never understood the sealant theory however the must be a reason behind it.

Less parts in the BOM for manufacturing.

Tighter tolerancing, do not have to account for variation is gasket thickness and "squishiness".

More consistent torque, and better torque retention for fasteners between parts do to gasket squishiness.

Less chance of shifting between surfaces since there is no gap created by a gasket.

I guess blown motors because of uneducated techs is much more cost effective and more mechanically sound. With Toybaru footing the bill it seems like they’d put some effort into remedying the issue

Why not use both? Back in my wrenching days, I used both. I used the sealant mainly to hold the gasket in place till the piece got bolted down -

I don't think manufacturers plan on the engine needing taken that far apart during it's expected life so it is not a consideration. If it wasn't for the valve spring recall nobody would be having this conversation about the FA20. I prefer the sealant over gaskets, even with it's PITA quirkiness I honestly think a lot of the failures have less to do with the techs being uneducated, and more to do with lack of care and trying to rush to make book time.

Excepting the timing cover and A/T pump delete cover,

it's all good. Right?
