the piston rings in my 1990 corolla are starting to go. Left it with friends over the summer and they let the oil get 2 quarts low. Stock compression is 190 psi, cylinders 1,2, and 4 are running at 140 psi, 3 is at 130. I was planning on driving this bad boy from NY to CA in a few weeks, and at this point I'm a little scared. What's the over under on me making it if I keep my oil topped off and don't rev it too high? Are there any quick fixes that'll increase my odds of making it there?
I'm BOOKED until I leave so I don't have the time for a rebuild. I was thinking if worst comes to worst I could get the cylinders honed (or bored, depending on how out of spec they are) and replace the rings.
Is it steady at those levels or has it been sinking even lower? Does it start reliably?

If they 'let' the oil get low, it was burning oil before they had it. which means the rings were shit before they had it.
if you just drive it to CA, you'll probably make it. Keep a gallon of oil, a new set of spark plugs, and tools to change the plugs in the car though.
Toyota blocks last a while, so the bores probably aren't in bad shape, just glazed. a hone, new rings new bearings will get you fixed up most of the way, but since it's been burning oil your valves are probably halfway to being burned by now.

Just found out about the low compression a few days ago, so no clue if it's decreasing or not. starts up like a fuckin dream.
Yeah I figured it had to be burning quite a bit. My spark plugs were covered in a beige powder coating too, not exactly sure what that indicates.

What the fuck is that on your hood?

That would be burned oil.
Here, have some oil-fucked valves. 230,000 miles on this car when this happened

$20 aliexpress tachometer, base model doesn't come with a tach

Here's an oil fouled plug from the same car, about 20,000 miles before the valve burned.

woof. They weren't that bad thankfully, which gives me a bit more faith in the engine holding up for the trip. If I were to do what recommends, could all that be done in a weekend?

Beige powder on plugs is okay. What you don't want is oily black deposits in the crevice area.
You said in your previous thread about your upcoming trip that you were going to attack some heavy iron rack to the roof of your car. What happened to that project?
