2010 Prius Leaky Gasket

Yeah read all the threads here JDM engine about $1,300 delivered to your door generally in most places on the East Coast You should be able to find somebody to swap that out for you for around $800 something like that and you're not anywhere near any kind of $8,000 anybody's quoting you JDM engines don't come from these shores and have lower mileage than anything you're going to find in the States generally speaking You could possibly get a Gen 4 engine and do the Gen 4 changeover whatever your poison not too big of a deal really unless you're just would rather get a newer car

 

For data/learning:

what are the miles?

was the EGR circuit ever cleaned, and if so at what miles?

 

May i suggest adding an oil leak sealant solution first. They sometimes work and theres many videos on youtube with people testing different brands effectiveness.

But if you are burning oil internally then its likely it could be piston O rings that are not expanding properly because they are clogged. In that case, you would want to try and unclog them. If you are lucky, you can do it without taking the entire engine apart. People swap the engine oil with transmission fluid and run the engine in maintenance mode for about 40 minutes and pour new oil. You can also try taking out the sparkplug and pouring vinegar inside and leaving overnight then sucking it out with a syringe the next day. Vinegar destroys rust and was most successful in loosening O rings stuck by rust. But carbon, i have no idea how well it does against. This should be a last ditch effort as its hard to say if it will even make it down to the third ring unless your piston walls are bored out already by the knocking. Theres also brand stuff you can buy that you pour into the oil and they claim to fix your o rings but its a waste a money if it doesnt work in my opinion.

Also try a thicker viscosity oil on next oil change. Less likely to leak or burn if it cant seep through.
