How much oil is being consumed?

 

5 qt every 1000 miles

 

OK....yeah....that's a severe problem.

 

Not sure how much oil consumption you’re talking about. A rough idea of how worn an engine is for me personally, do a compression test. You might want to follow up with a leak down test or other test depending on what You find on the compression test. Might just check your coolant too.

what you want to do about it is up to you. If I had a head gasket leak leading to random misfires and constant overflow of the coolant reservoir, I’d replace the engine, if I were dealing with a “worn engine” and I lost a qt every 5k, I might just do 5k oil changes And see how long it’ll live.

I think you can do only slightly better, maybe around $650 for a used engine (around Los Angeles), $800 isn’t an obnoxious price. There should still be a good supply oh Honda k24 engines, with all the accords having the same engine around. I recently got one from JDM of California (JDM of California – Used Japanese engines, transmissions and parts. Directly imported from Japan.). Depending on what you find, the other option is having the engine rebuilt. Used engine, more parts cost. Rebuild, more labor cost.

Best idea depends on what the condition of your crv is, and your emotional state. If the car is fine except for the engine, an engine replacement is very reasonable. If you need to do all the suspension work and more ...., don’t forget your emotional state though. Do you love this car, or does driving it make you feel like you’re dating the evil ex girlfriend?

EdIt - 5qt every 1000miles is significant to me. If there’s no external leak like you said, I would be curious to see if it were leaking internally vs. blowing smoke out the tailpipe all the time. Then I’d make a decision. Maybe you’ve already made the decision Without needing to know.

 

I like this car, that is why I'm thinking about engine replacement.
I want to buy used engine and rebuild it and use it.
If someone would tell me what possibly cause oil consumption.
One of the problem is; the rings for oil are stock and not working. I have to verify that first.
But, how?

 

Yes, with your amount of oil consumption and want to, it does seem like an engine replacement would be appropriate. Your $800 used engine price is reasonable as long as you can get it from a reputable source.

heres a link I found on google that discusses causes of oil consumption: Understanding How Engines Consume Oil

when i first suggested a compression test and leak down test, those were decent bits of information for me to decide on how I would personally proceed. However your 5qts or loss in 1000 miles is very significant enough for me to say, if it’s not leaking externally or internally (head gasket leak), then no matter if the oil consumption is from the piston rings or valves (or all of them) to me it doesn’t matter and I’d replace the engine.

 

Do these crvs have an oil consumption issue? I haven’t heard of it before.

Depends on how you define "oil consumption issue"

From Honda's perspective.... losing a quart between regular oil changes in some of the earlier generation CRVs is considered normal. Worst I ever saw though was about 1/2 quart in 7K miles in my gen2 CRV.

But what the original poster is presenting is a big issue.. so my guess is the internals of the engine are compromised.

 

@truefan31

Usually people complain about oil consumption as an “issue” in newer vehicles During the break in period, suggesting a manufacturing defect or an engineering error.

since this is a 2005 vehicle we’re talking about, it could have 500,000 miles on it. Or perhaps maintenance has been had been neglected along the way at one time. He is probably dealing with an end of life engine.

 

@truefan31

The vehicle has 150K and, if this is the end of life that means HONDA is is junk.

5qts every 1000k that thing has to be leaking a lot unless it is smoking so bad it leaves a fog behind it out the tail pipe. This isnt going to be something that does show where that much oil is going.

It is not smoking bad, only when the engine is cold.

I'm planning to see the pistons using inspection camera.

 

5 qts in 1000 miles and OP says how do you tell if its leaking vs consuming, pretty concerning there.

Camera as you call it will do nothing. Cant see anything that matters, only things a camera will show is broken pistons, valves hitting pistons etc. Only things that will cause serious misfires or engine not to run at all.

Smoking at cold start could be a number of things. Oil rings being bad, valve guide seals.

You need to look around for oil leaks before anything. That much oil has to be leaving more than cold start smoking (which is common for Hondas due to guide seals with higher mileage, consumption is 1at about 1500 miles at that point)

150k motor being bad wouldn't be Hondas faultx would be lack of proper care/maintenance during the life of the engine.

Agreed

 

I see everyone is surprise. OK.
There is nothing on my driveway.
Is it possible that the engine is loosing (leaking) the oil while driving?

With the camera I want to look at the top of pistons. If I see that there is a lot of clog, it means, the engine is burning oil.

My CRV was serviced at honda dealer until it got 100k.
When I said the technician that my CRV is taking 1qt every 1000 miles he said "That is normal"
However, It doesn't matter now. I need to find out what is wrong and fix it. That's why I have started this conversation.

 

OK. A little update.
It seems like it is some kind of external leakage. It is leaking when I drive, I hope so.

 

Roman - you have a serious oil leak somewhere, and if the dealership was servicing it, they should have seen it. Do not change the engine until you find the leak. I owned a 2002 Nissan Maxima. The engines were legendary for performance, but they just ate a quart of oil between oil changes. I learned to live with it. 5 qts/1000 miles is going to be a very stupid problem, and I am surprised by nothing under the car. Any decent mechanic should be able to find this.

 

Hello,

Nothing new for CRV's. The oil consumption. I have questions about it.
1. How to verify what cause that, my engine is not leaking.
2. What to do about it?
3. I'm planning to buy a used engine from a junk yard for about $800 and fix it, and replace the one in my CRV.
a. What do you thing about this idea?
b. Is it worth to do it? (DIY)
c. Is the price $800 OK?
d. Would you please share any opinions, experiences, advice's etc., please?
Of course, the best idea is to get new vehicle. However, I don't thing so.
Any thing would be helpful.
What do you think?

Thanks for helping me.

Ask Scotty Kilmer of Youtube fame.

 

Thanks,
I need to confirm if it was I think it is. I need a week or two.

 

Deleted ... (re re edited)

someone asked me why some of my posts say “deleted”. sometimes I reply, and afterwards realize it was just random chatter that added nothing useful to the thread. I tend to ”delete” those. I wish there could be a delete post on this forum, maybe there is and I haven’t found it.

 

thanks

 

My 2003 CRV EX has 239xxx. I only use Castrol 10w40 with STP. I want the higher viscosity with the wear on bearings after that many miles. I won't use synthetic because of it causing more leakage. That is fact, not just my opinion. I do the same in my wife's Jeep Patriot that is no longer under warranty with only 71xxx.

 

I think the issue of leaking cars using synthetic oil is from back when Mobile 1 came into being. That was indeed thin oil. Modern day synthetic oils are mostly variable weight like the 10w40 you reference. People have and believe what they want to believe about their oil use. On this forum or any other mechanical engine related forum. You are far out of warranty so not using manufacture recommended oil type is no longer an issue for that.

 

OK,
I got some updates.
Some of you people said, I had a serious leakage. You were correct. It is through exhaust system. Oil rings are stocked. It is confirmed by Honda service.
Now I have three options:
1. Engine restoration( around $500) they don't guarantee results.
2. Fix the problem, replace the rings.
3. Replace the engine.
Las option: Get rid of the car.

Suggestions?

 

#1 - sounds too cheap, i.e. IMHO an engine restoration would include things like ring replacement, cylinder honing, valve grinding, valve guide replacement, head finishing, etc. All this might be more like $1500+.
#2 - if you are going to get rings replaced, why not do all the other stuff I mentioned in #1 above.
#3 - always a crapshoot when buying used parts. Don't know the spare parts maintenance history. Getting a new/newer replacement engine depends on what you already have invested in your vehicle & what you believe you can afford to invest to keep this running.

Tough choices all around. Only you know what your financial resources are. As others can attest, the used car market today is a seller's market. Be prepared to fend off other people looking to do the same as you.

Good luck. Keep us informed.

 

Does any one has any experience with JDM engines?

Kazoo2U, this is about restoration not rebuild. Jus try to free up those rings.

 

Now I'm confused [more so than normal].

I know what an engine rebuild is & what all it all entails. Exactly what is an engine restoration?

 

Kazoo2U
Using chemical to clean oil rings and free them up to do theirs job.
Details? Call honda and ask.

 

Marvel Mystery Oil?

 

Are you sure, 5 qts in 1000 miles? Wow. I think my '04 is an oil drinker but it uses about 1.5 in 5000 miles.

 

What Kind of question it is?

 

If that amount of oil is getting past valves or oil rings - then the car will be putting out significant amounts of blue smoke - perhaps not all the time but under hard acceleration or on overrun. My personal view is if it is burning it then cut your losses and sell.

Hey Roman666c,

I feel your frustrations. A couple of questions. Did you only get the diagnosis from Honda Service?
If so this is what I would recommend. I would try a local independent Honda Specialist shop if you can. The reason is they tend to work a lot on older Hondas and know a lot about the K-Series engine. For example, my mechanic shop is family owned. Its a semi retired guy who is in his 70s and his son who runs it now. There is decades worth of knowledge as they deal with this sort of thing every day.
I would start with that first. If you cannot find the probable source of the leak and if the vehicle itself is in good condition. It be worth changing the engine. The engines are generally very reliable.
The engines do burn a bit of oil. You will have to top up now and again. But what you posted was excessive oil consumption.
I spoke to my Honda mechanic a while back. He changed the engine on a old CRV. The body was in good condition and found a used engine cheap. So its not uncommon on these.
Good luck and let us know what you do.

Hopefully he finds the right shop/technician that will not take advantage of him. It's hard to know when you have limited automotive knowledge, but the internet provides a way to search for the information. There are guys out there that do this on a regular basis. Are they going to use a junk-yard engine or a rebuilt engine? Who rebuilt the engine? Is there a warranty? Before the pandemic he could have bought a used Honda CRV for a little more than the cost of replacing the engine. Maybe a 10 year old one, but now the prices have increased substantially because of supply & demand. He will have to run the numbers, including how long he intends to keep the car.
