Hi, I replaced the engine of my CR-V 2012 (118k miles) with a used engine tagged 70k miles on it. My question is when Honda uses a used/reman engine, do you replace these components like belts, gasket, cylinder liner, water pump, timing chain, bearings, etc. with new ones?

 

No. It's not remanufactured. That is why they tell you the miles.

 

Do you normally use new belts, timing chains when replacing with a used engine?

 

With the engine removed, this is a great time to replace some items. You should definitely replace the timing chain. And while they are removed, the drive belts. No sense putting an old belt on. Also inspect the valve clearances and replace the spark plugs. Personally I would also replace the PCV valve, fuel filter, and thermostat just so I know they are good. Inspect radiator hoses and replace any that are bulging. I'd suggest looking the 'new' engine over for any obvious leaks (e.g., oil pan gasket) and fix them while it's relatively easy to do. - That is all I can think of. Enjoy your 'new' engine!

 

Thank you for your suggestions. I was little late to post my question to the forum. I just got my vehicle back with the new used engine yesterday. Its running much quieter. The agent said I had a bad bearing which one she was not sure, also had a bad motor, I believe that's the water pump. I should have talked to the technician directly. Well I have learned a lot with this repair.

 

A bad bearing produces a tell-tale sound, but it's difficult to identify the specific bearing that failed without disassembling the engine to look. When a bearing fails, the techs will say that motor/engine is bad.

I didn't pick up that you were having a shop do it: My list was more of what I would replace if I had it in my shop. If you had someone else swap it, they probably did NOT do ANY of that, unless they saw an obvious problem with something. Which is fine. That is how it has to be if you are paying them because you can't have them nickel-and-diming you for every little thing. A good tech will inspect everything as it goes back on and let you know if they see a problem. So even though they didn't replace all of those things, you can have some confidence that the car is good. At least you know someone put eyes on everything.

At 113k miles, your bearing probably failed from lack of lubrication. I am guessing at some point it probably ran low on oil, or had old or contaminated oil in it. If you are wondering about the bearings in your new engine, it's a bit of a gamble. Because they are used. And you don't know if the previous vehicle also had lubrication problems or not. Generally used engines come from vehicles that have been in accidents, and so they were running at the time. So that's good. And a Honda engine will last 200k-ish or more. So you are probably fine. Also, the new engine probably has some kind of warranty.

 

Thank you for your time to give your input here. I do have a 1yr/12k miles warranty on this engine. Hope it will go more than a year.

There was a sound coming from the engine like few months earlier but I just ignored it as it was only sometimes when I do a quick acceleration and goes away when I put some load on the trunk. I thought it was coming from the transmission and changed the transmission oil as it was due. I had also noticed the quicker oil life degradation shown in the dashboard but thought it may be a software issue and may have been linked to the cruse control that was not working around that timeframe.

Lesson learned don't overwrite oil life without changing the oil and do not ignore any sound coming from the engine. Now I know where to come when there is a doubt.

 

Old engine was burning oil?

 

Probably yes.
