Hello All,

I could really do with some help and information from you all regarding an issue I am facing...

After years of waiting I finally got my wish of owning an S2000 and bought a 2007 model four months ago.

Its on 27k, one owner, FHSH etc etc - Had a clutch issue, Hondacare covered it under warranty as no wear showing, but on return the clutch bite point kept changing (it started doing this before new clutch fitted), so put it back to Honda.

They have fitted a new master cylider but not fixed problem.

Now they have found end float and have said that the there is a thrust washer issue creating the end float and clutch issue. I have seen this is referred to as 'crank walk'

They have a master tech guy in the dealership who has never seen this issue before on a high performance engine of honda's unless the engine has been starved of oil, they say they need to strip the engine to fit new washers and there is a chance of a bent crank shaft.

In short if the warranty may cover it unless their engineer can see evidence of oil starvation at some point by looking at the stripped engine.

The car has been serviced on schedule since purchase, the dealer confirmed the car had had no issues since purchase and up until the poin tI bought it (privately).

I have done 6k miles since last major service and the car has not 'eaten' any oil since that service so i am assuming it hasn't eaten much in the past, but am concerned as the dealership say its the only reason they could think of why this may of happened.

I am sure you can understand that faced with a bill of betwee 1500 and 2500 I am looking to find out if there are any known faults or anyone out there who has faced the same issue etc etc etc..

anything would be a help...

appreciate any contributions any of you can make.

Cheers

 

Thrust washers only are really only under load when you operate the clutch. Apart from that they really aren't loaded up. If the oil level gets low then typically the con-rod and then the main bearings would be most likely before the thrust washers went. To get the thrust washer to go you'd have to get the engine to be low on oil and then stay with your foot on the clutch for an extended period of time (think hours).

Based on an assumption that the dealer actually knows what they're doing and have given a correct diagnosis of the crank moving then I'd suspect a manufacturing fault within the engine. Thing the engine is too old for it to be the thrust washers put in the wrong way around.

Possibly poor surface finish of the crank thust face causing accelerated wear on the washers. Be a proper whatsit to prove without a lot of precision measurement gear though

 

Thanks fluffyninja,

Your comments give me some confidence as my problem is I have to agree to 1500 labour cost and hope there is no sign of oil starvation as if not I won't have to pay!!

Still can't believe it, had five hondas vti, itr etc and they have all been bullett proof, obviously been lucky up until now but still have high expectations of them.

I saw a post where s2ki referred to thrust washer issues on EV04s, have sent direct email to him but be interesting to hear if anyone else has had this problem in future replies!

Cheers

 

It used to be quite common on Evo 4 & 5 IIRC.

 

one reason why you should never start a car with your foot on the clutch. especially if you have a heavy clutch plate. it puts a load on a dry thrust bearing if an engine has been standing a while and the oil has drained back into the sump.

 

^^^^^^

Except when you need to have your foot on the clutch to start the car!

Al la immobiliser switch

 

^^ JDM cars will not turn over unless clutch pedal is depressed!

and i dont mean sad !

 

^^^^^^^^

probably why some cars have problems then


but i'm used to working on old British cars with 300+bhp. some put so much drag on the engine they wont actually turn over.
