94 Corolla Oil Burning

[94_Rolla_Guy]

Kinda stumped... car's been burning about a 1/2 liter every 1500km Tonight i went to give it its usual 1/2 liter for its 1500km and it drank almost 2 liters any ideas what could be causing this dramatic increase? should i be chaseing bad piston rings or valve seals, Im confused and im getting irritated by this car...

that's curious indeed.

I can only imagine a few things: Do you usually travel short distances and had a longer distance
lately? Has winter ended and temperatures are on the rise again?

In deep winter, especially if you travel short distances, oil is mixed with condensation and
also with fuel, because of the enriching at cold start. If the oil doesn't get hot enough to allow the fuel to evaporate it'll remain in the sump. Once the oil does get hot, the fuel and water condensation evaporate and so you observe a higher than normal oil consumption.

That's the only thought I can share. Other than that, keep observing how it behaves from here forward.

Cheers,

does it smoke alot (like a big puff) on start up, if it does then i would start with the valve seals, the only thing is if you pull the head you might as well do rings while you are at it otherwise the tighter head can cause excessive oil blow by the rings
