4th Gen to 3rd Gen engine swap - Pricing Question

I have a 2010 Prius III with 162k miles and it's giving multiple cylinder misfire codes. From my searches here it seems the most reasonable course of action is to do an engine swap over a head gasket replacement or rebuild.

I've found a shop here in the Los Angeles area that is doing 4th Gen engine swaps for the 3rd Gen Prius. I have a quote of $3,500 with a 12K mile engine, it includes a new water pump and egr cooler and manifold clean out, all other parts and labor are included plus a 2 year warranty.

Does this price seem reasonable?

Thanks!

 

Thanks for the reply, I recently purchased the car used with 157K miles on it. The actual oil maintenance history is unknown but the overall condition of engine and car seem to show that it was well cared for. The records with Toyota show that the previous owners did all the scheduled Toyota maintenance. Those records also shows the EGR valve was replaced due to "knocking at startup" @ 133K miles and a new water pump at 143k

No oil consumption since last change @ 157K
No overheating or loss of coolant
No stop leak products used (at least not by me)

The same shop quoted a top only rebuild of my engine @ $1,500 or a completely rebuilt 3rd gen engine for $2,500.

At 162K miles this engine is quickly reaching a point that repairs on it seem less effective than replacing it with either a rebuilt lower mile 3rd gen engine (hard to find) or with an 4th gen with sub 50k miles (which are plentiful).

 

Hmmm... the knocking on start-up has happened several times over the last few days and then today with the P302 code I just assumed that from what I have been reading here on the forums that head gasket was the most likely culprit.

Just stepped out to the car and checked the oil level to make sure, level is good and color is fine and coolant is at the full line.

 

Thanks @The Critic and @Mendel Leisk for the input, I'll have a look at the spark plugs in the AM and I'm also looking at EGR cleaning info... both projects look like things I'm capable of doing myself and my weekend is clear to do it!

 

I just finished a couple hours ago doing my EGR cooler/pipe/intake manifold cleaning along with putting in a new PCV valve and installing a oil catch can.

I took my time, gathered parts and tools on Saturday, started pulling apart the car on Sunday morning had the parts off by lunchtime and took a break to take care of some other stuff, came back later in the afternoon once it had cooled down and started spraying down the EGR cooler with oven cleaner, letting it sit for 30 minutes and spraying in some more, repeating that till the entire can was soaking inside the cooler for the rest of the night.

This morning I took it to the local spray wash and blew out all the gunk, so. much. gunk. Good as new. Manifold was very easy to clean with part cleaner and a brush kit I picked up at Harbor Freight Tools. The EGR passages, 3 out of 4 of mine were basically blocked and the 4th was not far from it. PCV valve was super easy since you have the manifold already off as well as the catch can install. All back together by 6 PM. Cleaned myself up and took the car for 60 mile spin on the highway and I can totally tell a difference in the power and how smooth the engine is sounding. Fingers crossed the gummed EGR circuit and intake manifold were the issues and not a gasket.

 

After a little over a month without the rough shudder start up, this morning I started it up and it happened. I've put a little less than 1000 miles on the car, no oil used in that time and no drop in the coolant level. The only thing I didn't do while I had it opened up was change the spark plugs or coils, should that be the next thing I look at?

Just to restate, I gave the EGR pipe, cooler and manifold a full clean out, changed the PCV valve and installed a OCC, which I checked a couple of days ago and it had a rather minor amount of fluid in it.

 

No long sits, I use the car nearly every day. Not long drives, but I take the time to let the engine run the warm up cycle at each start.
