Car Talk

Unread postby Raion-Fox » Thu Apr 20, 2017 5:46 pm

So yesterday, my girl's 2013 Sonic's cylinder no.3 decided it was too hot and cracked, so I've got a dead rebadged Daewoo in my back yard I have to replace the engine in and then sell off. Clearly, after such a boneheaded event, I've made my girlfriend promise to let ME handle her car choices. She sucks at choosing reliable vehicles. She's getting a used IS300 after I sell this off, since my buddy has one he's gonna sell to us for a good price, and that way we don't need an auto loan.

Other than that, parts for my Miata's AC repair came in. New condenser, drier, compressor and PAG 100 oil with plenty of r134a. Fingers crossed when I get around to installing it.

Outside of that, the Miata needs some rust repair on the right wheel arch, right rocker, right side of the truck (inner arch) and the left rocker, although thats far more solid than the right, and a new front core support since the one in there is tweaked a bit, I straightened it out using the old come along trick, but that's not perfect nor safe lol. I know it's probably gonna cost more than its worth, but its *my* money pit lol.

I wonder why it happened. Bad quality oil? :roll:

GM's aren't meant to last more than 3 years. This one was on borrowed time.

The only good thing about GM cars is that you can lease them for $39 or $49 / week. Which is honestly not a bad deal if you don't care about cars and don't live in an area that has a good rideshare/carshare program.


But if you go through all the trouble to replace the block why not keep it?

Because I refuse to work on it after this. The engine bay is tiny and there's no way to detach the engine from the transmission so I have to remove them together. I want to fix the car and make it someone else's problem.

The IS300 I'm buying her after the car is sold is far far more reliable with the legendary JZ engine by Toyota. Unfortunately my girlfriend is smart when it comes to art and fashion, her majors, but she has been forced to admit she was a bonehead buying the car. I actively discouraged her from buying it but she didn't listen.

I have asked her to never buy a car again and not take my opinion seriously. It's costing me the weekend after this, beer and pizza for my helpers and $900 for a replacement shortblock, mounts, headgasket and headboard and a timing belt kit, since I'm changing the engine, why the hell not? Plus machine shop work on the head.

The engine in the Sonic is a terrible design. It is an open deck with very thin aluminium walls, insufficient water jackets, and valves that aren't adjustable easily. You have to replace the entire rocker/tappet assembly.

What is "plenty" of r134? The 1999 miata uses 20 ounces. Pretty much every AC machine I've ever seen takes a 10 or 20# tank. If you have a separate vacuum pump, scale, and recovery tank (old school!)... 2 pounds would be "plenty"...


Well I washed my wife's car. Took the 90 seconds to adjust the trunk lid stoppers so the inner and outer tail lamps actually line up with each other. I've never seen another challenger that has these set properly, even brand new they are waaaay off and nobody cares :/ Could probably do with another slight tweak but it's 90% there.

Should probably file under "what pointless thing are you doing now" but starting on a prototype wire harness for an electric bus... I guess it counts as car talk. Notice, I got smart and took the hood off the hinges after the *first* time I hit my head. Normally it takes 3 or 4 goose eggs before the hood comes off :lol:

P.S. see the "bone" creeper? 300% recommended!
