Hi guys, looking for some advice from the diesel gurus out there.

Picked the wife up from work tonight and within a mile the oil warning light came on. Car had been running fine until it came on. I'm check the oil level pretty regularly so i was certain i was not low on oil. Stopped the car and checked the level, and it was sitting around half way between the min and max markers. I let the engine cool for about an hour, topped it up to the max mark with some edge 0w-30 and tried starting it again. The engine fired first time but was sounding pretty rough, seeing as my dad's place was only about a mile away, i nursed the car there, trying not to go over 1300rpm (usually changing gear at 1100rpm) I did notice an occasional mechanical chirp coming from the car when coming off light throttle (this only happened after the light came on, car was fine before), i'm guessing the turbo was running dry so i will probably need to buy a new one very soon.

Checked the receipts for the car and the last service, with oil change and new filter was about 8500 miles ago, (i had planned on getting to national over the past few weeks to get fresh oil in but never got round to it).

Any ideas as to what could be causing this? blocked oil passage/failed oil pump?

thanks in advance for any replies

Could be failed pump, clogged filter, CJ hex.... are there any DTC's?

Is it a genuine Honda Filter?

not had a chance to look for any fault codes but the engine warning light did not come on. It was a genuine honda filter, but i have a honda filter in the house, so will do a complete oil change tomorrow (need to take my dad's car back to him anyway) and hope it is just a clogged filter.
 
Good luck bud!

Keep us posted. The oil light or any oil pressure warning puts the fear of god into me :(.
 
Yep no light matter that, i would check for errors asap you dont want the engine spewing its guts on the road.
 
Thanks CJ,

I only ran it for about a mile to get it to a safe place to leave for the night. Car will not be getting moved until fixed.

Update on the oil filter: checked the receipts for the car as the prev owner was pretty good about keeping receipts for servicing etc. Oil and filter were changed 8000 miles ago, castrol edge 0w-30 oil used, but........its not a honda genuine filter thats on there. its a fram :angry: Have done a quick search on the net, and it looks like these filters can clog fairly easily. CJ, in your opinion, would a clogged oil filter cause the symptons i've described above??
 
I would say yes, but still worth getting it checked to make sure no harm has been done. With any luck you have caught it early enough.

Our collective fingers will be crossed for you.
 
CJ has a valid point it could be the chain. Is the car noisy, rattly, the accord diesel is smooth sounding when working normal.
 
Thanks Dan

I really hope i have caught it early enough as i cant really afford to be shelling out on a new engine :(

I'll do the oil and filter change tomorrow, if the engine seems to be running ok, i'll get her booked into Hyndland Honda for a checkup and pray to the gods of Honda that no harm has come to her.
 
do'h, its not looking good for my finances then :(

(edited for swear filter, didnt realise it was going to pick up b****r)

Had a closer look at the previous servicing and it gets worse. Its not quite 20k miles, but the previous oil/filter change 13.5k before the last, and they used a 'blueprint adh' filter. previous service just under 12k miles before that, and another blueprint adh filter :angry: So it looks like it not had a proper honda filter on it for at least 30k miles
 
Dude get it to a Honda specialist and try not to think about it until then. Have a stiff drink to calm your nerves.
 
If you do have a happy outcome, take a tip, change the oil at 6,000k and the oil/filter change at 12,000k, That halves the schedule in the books, much better for engine and your pocket. If it comes to the worst take a look here.

That does look too good to be true... is the N22a the facelift?

This is the garage in the ebay link

Would be interested in the guarantee on the work and engine.

Handy place to have in the background fro us Diesel owners.


hhmmmm 3 to 6 months warranty.

6 months on new stuff? That is not strictly legal. Another example of a company either not knowing or trying to circumvent the law.
 
This really doesn't sound good at all. As CJ says, for the ICTDI to make unusual noises is not a good sign. It's known for its exceptionally quiet engine normally.

I personally don't think an aftermarket oil filter will cause such issues (fuel filters are a different story). But lengthy oil change intervals like those are not good for this engine..

I had my timing chain done under warranty last week and the total bill to Honda from the dealer was around £2k inc labour (I have the receipts). The bulk of the cost is injectors at £250 x 4. If you can get away with not needing injectors i.e. if the old ones don't seize in then you can have it done for less than £1k.

This is ***uming it is the chain anyway.
 
:blink: I really hope it isnt the chain then

Just realised something though, when i said it was rough, it wasn't lumpy or hesitating or jerky or anything like that. It sounded more like my old V6 TDI audi, but it still idled and revved ok. It just didnt sound as smooth as it normally does, it sounded as though it was being starved of oil, and the squeal i heard did sound like it was the turbo being starved.

if i do end up with a happy ending i think i'll be changing oil every 4000miles :unsure:

car currently has 159k on it, so well outside the 125k warranty for the timing chain.

Ok, i'm getting a bit confused now, it is the timing chain we're talking about or the oil pump chain? or is it one chain does both?
 
Sounds like a weak oil pump mate, could actually be clogged with sludge. Are you sure it's been run on 0w/30 before? What mileage is it on?

Its on 159100 and something miles, invoices are stating 0w30, but then again, considering i dont know how good or honest the garage used is, and as they considered it good form to save less than a fiver by using an afetrmarket oil filter, i'm not confident that they used what they said they used
 
The best thing going for you at the moment is that you spotted this straight away. Dwell on that and your new servicing regime. Until it is seen by someone who knows and understands this engine you will just be chewing yourself up.
 
If its sounds like a vw tdi, then its chain imo. just think you got 160k onit if it hasn't been looked after a oil pump would be the least of your worries. I think you have a well maintained engine to get to 160k without needed a new chain.
 
wasn't faddy changed recently. I've always changed under manufacturer guidlines with correct oil and its showing signs.
I did think that, but i think driving style and enviroment makes a big difference. Obviously I agree with you totally poor oil service is the real killer, but honda recommend 12k intervals?
 
A thread or article explaining how all this works would be great... Our iCTDi's aren't like the other tractor engines out there and we are at the mercy of the dealers when it comes to these things. THAOC and now TA have helped immensely, but some of us still clutch at straws when it comes to complicated issues like this.
 
Yup my car is maintained to quite **** standards really, but my chain also needed doing. It wasn't very bad, but there was a slight noise there and I didn't want to let it go past the 7 years.

As CJ has pointed out, the pre facelift cars will almost inevitably suffer the timing chain problem as it's down to the original chain and sprocket design. The revised engines in the facelift should not suffer this but as far as I am aware all ICTDI's are covered under the warranty.
 
well, car getting picked up monday or tuesday and going to the garage for diagnosis. Gonna try not to think about it until then. Will keep you guys posted with what happens. The timing chain wasnt making any noise when the car was running, but best being on the safe side which is why its being picked up by the garage

Just read your thread,

Definitely done the right thing, getting the garage to pick it up.

Hope all goes well for you

Best of luck
 
i would suggest if you have little or no oil preasure, your oil pump chain has snapped. i have seen this on 3 ictdi engines so far, the timing chain never seams to snap but the oil pump chain is the first to go and the abnormal noise may be part of the chain picking up now and again or rubbing against the timing chain. dont run or drive it untill someone in the know has looked at it, but if you say the oil light was on and you have a noisy chain i would say the oil pump chain has snapped
 
Garage were unable to pick car up and have now rescheduled for tomorrow. So i should hopefully find out tomorrow/thursday what state my engine is in. I've been having a look at engines on fleabay etc, and was wondering what the difference is between the n22a1 and n22a2? Would the n22a2 fit my car or would it require changes to other parts like the gearbox?
 
The gear box would be different bud - 6th gear 'n all. Not sure how much work it would be to change - if it is possible.

Fingers crossed that yours will be OK!
 
Thanks Dan,

considering gearboxes are going for as cheap as 350 for a 6 speed on fleabay, changing to a 6 speed box might not be a bad idea. Just depends on what else else would be required really
