Hi Prius owners, appreciate your takes on the following.
Toyota Prius V 2013 - mileage 140000 miles as of the time of trouble code.
I replaced all four spark plugs, and swapped ignition coils on cylinder 1 and 2. The code is still present.
An OBD scan shows Cylinder 2 misfires persistently, three other cylinders have 0 misfires.
I did notice the coolant level was very low, however the spark plugs, when I changed them, looked nothing like suspicious, just regular wear and tear. I've had the car for a little over a year and made around 40K miles on it, I don't know how fresh or old the spark plugs were before I bought the car. The engine oil is normal color, nothing looks like it might have been mixed with coolant.
Took to a shop, and the guy opened the hood literally for 3 seconds, gave it a glance and said, "I know what it is, it's the engine gasket, it's gonna cost $1,200 to replace." Did not explain in detail what the problem, other than I must have overheated the engine at some point (because the coolant level was low, I take it). That was it, the entire talk with him. Basically, the problem is the gasket, so if you want it replaced it's going to cost you a bunch of money.
I've never had a "Coolant Temperature warning" light come on, ever.
However, what he told got me thinking that the probability he was scamming me might not be zero.
Having watched a bunch of YouTube videos, thinking of possible reasons for the P0302 trouble code (Cylinder 2 misfire), which has been the only code I've been getting, I'm actually split between the following options, or any combination thereof:
- engine gasket is bad due to engine overheating due to low levels of coolant - bad news, needs replacement, might spell doom for the engine and indicate other more in-depth issues;
- intake manifold being clogged with carbons due to a fairly high mileage (140K give or take); - no so bad, cured by disassembling and cleaning;
- EGR cooler clogged causing misfires on Cylinder 2 - but then again why only Cyl 2? - not so bad, cured by disasembling and cleaning;
- PCV valve - not so bad, cured by replacing or cleaning.
Thoughts? Im excited to see what they'll look like and how the performance will be.

This is a fun side project I've been working on for a while.
Basic rundown is:2005 Toyota Echo. 2014 1NZFXE engine from a Toyota Prius Type C (1500cc) Silvertop 4AGE ITB. Jun 264 deg cams. BC valve springs. Link G4+ ECU.
The engine makes 141hp at the hubs, has a 9000rpm limiter. I was super stoked to run a 13 in it, on my 3rd and final run of the night. I didnt get a chance to dial in the tyre pressures and launch rpm any further. But suffice to say, I was incredibly stoked to get a 13.8 out of this combo!

They say it's hard to kill a Toyota motor from the 90s, an era where they put tons of money into over-engineering engines just to humiliate the domestic market. I wasn't aware what this meant until I bought a very clean, but very neglected '92 Celica GT with a 5 speed last April.
From the early 90s on, the standard 4 cylinder in the Camry and Celica was the iron block 2.2l 5S-FE. My 92 Celica had one of the most neglected 5S-FEs you could imagine. It had been making a ticking noise the entire time the previous owner had it, because the owner before him evidently ran it out or oil until it started making noise. I proceeded to drive it 200 miles home before it finally spun a rod bearing. (If I was smart I would've put heavyweight oil in it and it would've been fine for longer). When it spun the bearing at 3k RPM on the highway it made an awful knock like a jackhammer, sent smoke out the exhaust and I could literally hear chunks of metal falling into the oil pan and going out the exhaust. It died and coasted to a stop. (I would later find chunks of metal over an inch in diameter in the oil pan after pulling the motor). in that moment I knew for certain it was dead. On a whim I tried cranking it over. The fucking thing started right up and idled literally with chunks of rod and piston missing. Just out of spite it was like no, fuck you, I'm not ready to die yet. I proceeded to drive it to its final resting place, and then drive it up the ramps where I pulled the engine. I guess us mere mortals cannot kill an iron block Camry engine, perhaps it takes an act of god.
What's the consensus on the best overall motor ever made by Toyota, in terms of reliability, durability, and day-to-day usability, and why?
My first thoughts would be the 3rz-fe, 1fz-fe, and 2uz-fe, at least as far as the gas engines go. I can't comment too much on the diesels.
In the case that it does need replacing, what would be a fair rate? They’re quoting me at $2,800
Should I go to a local mechanic or is this trustworthy?
