The K24Z Series
The 2007 Honda CRV's K24Z1 engine replaced the K24A1's. The new 2.4-liter engine has cast-in iron cylinder liners and a two-piece die-cast aluminum engine block. The oil filter is now located in the block's lower center. There is an internal stabilizer unit and a hardened steel crankshaft inside. The ratio of compression to entropy is approximately 9.7:1. A 16-valve Twin cam i-VTEC head is also included with the engine. The old 2-stage intake was swapped out for a unique 1-stage RTB air intake with a drive-by-wire throttle body and an electronic ignition system. The high-density catalytic converter in the exhaust system aids the engine in meeting emission regulations. Honda's technicians had to make adjustments to the K24Z1 in 2008 to make it compliant with new environmental regulations. Because of this, the less potent K24Z4
model was created as a response.

A Buyers Guide To Buying Used Engines From Auto Wreckers & Salvage Yards
Some so many people buy second-hand car engines from wreckers, mechanics, and places like eBay. And they don't always know what they're getting themselves into. As you'll discover in this guide to buying an engine of a wrecker or salvage yard… it's not always as easy as it looks!
Whether you are looking for a vehicle that is cheap to run or free one if you are lucky enough to find yourself with access to a full-functioning running vehicle, then why not strip it down for parts? That's exactly what thousands of Americans do every weekend at their friendly neighborhood auto recyclers/repairers / 'wreckers.' For this article I will refer to all of these auto recyclers, mechanics, and wreckers as 'wreckers' for ease.
The market is flooded with car parts for almost every make/model. You can find them in your local paper or shopping around on the internet. By typing 'auto wreckers' into Google, you will have access to more listings than you could imagine. There are thousands of listings across the United States alone! And this will be an example of one week's worth… not the best seven days but a typical week all the same! Here it is:
Looking at this list (and yes, I manually weed out the adverts that were invalid or incorrect), we can see well over 2300 listings found in one single US state for parts! That's enough to keep even the pickiest car buyer happy.
So what can you expect when buying an engine of a wrecker/salvage yard? Well, it's never going to be relatively as easy as popping down to your local mechanic and asking for one, but it's not always the complex process that many would like you to think it is either. Buying an engine from a wrecker or salvage yard is all about doing your homework beforehand, so you know exactly what you are looking at when inspecting the engine later on. This will also give you some idea of what sort of price range you're looking at too! Once done with this guide, I'm sure you'll feel much more confident in your ability when purchasing online… who knows… you might even sell a few spare parts to other customers in the future.
So let's start:
Firstly, why would anyone want to buy an engine from a wrecker?
When people buy engines from wreckers, it's usually because they either can't afford or don't want to fork out for a brand new one. If your only source of transport is down, then buying an engine online might be your only option as nobody local will stock it, and if your car is too old for most mechanics to work on, then you're kind of stuck looking at the wrecker/vehicle dismantler. Another reason would be that you need quality used replacement parts, and buying directly from a wrecker gets around the factory problem of:
'New = better'
This is a massive misconception in car parts manufacturers. It's true sometimes, but not all of the time. There are so many brands to choose from when buying new replacement vehicle parts or accessories that it can be challenging to pick out which one is best for your situation. An engine might be listed as 'new/remanufactured/rebuilt,' but how long will it last? How much has it been used previously? Has it been repaired correctly or even at all? These questions need to be asked if you want a quality part that isn't going to fail on you straight away. Buying second-hand / pre-loved means bearing all this in mind… however, depending on who you buy from, you never know what you might get. The best thing that anybody can do is find out all they can about the part (if it's available) and then determine whether buying it or not will be a good idea!
Some of these questions I have just mentioned may seem very obvious, but with so many manufacturers, makes, and models being produced every day, there are plenty of parts that require extra care when looking for them. Take engine oil, for example:
In my opinion, synthetic / semi-synthetic is the way to go if you're purchasing a used car engine. It lasts longer in between changes and usually means more miles per liter of conventional oil, saving you money over time by paying the pump. Ask anyone in the know, and they will tell you that it is the best thing to use in a car, but what about engines? There has been some debate on forums across the internet about whether it's advisable or not due to the cost difference. Synthetic / semi-synthetic oil can be 3-4 times more expensive than standard engine oil and, therefore, may not be the most financially friendly choice for your engine. I wouldn't risk it unless I had no other choice; conventional engine oil is refined, but knowing how long it lasts compared to synthetic will give you a good idea of how often an oil change might need doing.
And then there are sparks plugs:
Again, this one is significant when buying any used vehicle parts as if they haven't been changed before; it may well be time now. I always find that going to a wrecker and buying parts off them is like playing Russian roulette, you can do your best to inspect the product, but unless you know what you're looking for, then it will become tough. The same goes for sparks plugs that can cause intense damage if not done correctly… this sort of thing gives me nightmares!
You need to make sure you know these things or at least research about them before handing over any cash because car engines don't come cheap, and getting one repaired isn't worth the risk. My advice would be: look for a reputable dismantler who offers warranties on each part they supply; even better if they also give you a few years warranty!
Considering you can spend up to $3000 for a new engine, then paying an extra couple of hundred dollars might seem ridiculous… but it's your car, and it's that or nothing. After all, if the parts are second hand aren't they already used? Why not buy them from someone who has checked/changed them, so you don't have to? Expensive doesn't always mean better; ask around about different dismantlers in your area before picking one yourself to see which one offers the best service at the most reasonable price. There is usually a shop around somewhere specializing in auto repairs; go there first because they will be the best priced. Don't just go into any old wrecker thinking everything will be alright because it is wont… not unless you like taking risks.
