I had a spare engine that i sold the other day to someone. I bought it in full working order but he has contacted me to say that the crank is bent and the engine is unusable??

He's only had the engine 2 days and i wouldn't know how you would be able to tell (i'm no mechanic)

I have spent a bit of time googling it and can't find any instances of S2000s having bent cranks. Only thing i can find is that the pulleys simetimes get bent.

Does this sound plausible? If so i'll give him some money for a new crank, but it seems unlikely.

Any advice or similar experince details appreciated.

Many thanks

Rob

 

Tricky situation, and it's your word against his.

When did you buy the engine and do you have any comeback on them?

If the crank is bent i'd be worried about the rest of it!

How does he know it's bent? Presume he has stripped it down?

 

I got the engine with the turbo'd S2000 i had in p/x. I was told that it was a healthy engine and was bought as a soare as the guy was going to have a full forged build at some point in the future

There were no signs of any problems with the engine and would pressume that if something had bent it would have blown a hole in the block?

The guy only picked the engine up on saturday and it was fully built as if just removed from a car (gearbox attached, manifold attached, loom, alternator etc still attached), so he would have to work pretty quick to strip it down.

How would he be able to tell just by looking at the engine?

I have read stories of the pulleys getting bent, causing a wobble, but nothing at all on the crankshaft itself?

Thanks

well the engine would only take about 5-7 hours to strip down.

other than that a newcrank from Honda is £1100

 

Bent the crank?!

Jog on.

There is no way that crank would bend without the engine blowing to pieces.

I hope, for your sake, that you recorded the engine number because I wouldn't be suprised if he is trying to pull a fast one.

 

oohh he has the right idea ^^

 

To be honest thats what i thought as i can find zero posts worldwide relating to a bent crank on an s2000!

There was no sign of any holes in the block, no metal fragments anywhere and the oil was still normal.

Everyone i have spoken to says that the only way to bend a crank really is in a heavy impact crash, but the engine was immaculate with no sign of any impact anywhere.

I think it must be a bent pulley, but i want to make sure he's happy with the engine so if i have to buy him a second hand crank then i suppose i'll have to do that, but i'll push for a new pulley first.

I can't get hold of the guy at the moment but i have asked him to tell me how he knows it's 100% the crank and not the pulley.

Thanks everyone for advice and input, it's making me feel a little better

I'd check that bit of info first, then if he insists it's the crank, tell him to start running as you'll report him for fraud unless he can provide substantial evidence.

It'll take some amount of effort for him to bend a crank in order to rip you off.

 

He's gone quiet so far so i'll wait and see.

I've sent him a message letting him know that it is practically impossible to bend a crank without the engine ending up in pieces and i'll pay for a new pulley wheel but that's it.

I'll keep you posted.

Thanks

Rob

 

the standard cranks weigh about 15 kilos of cast and machined metal that wont bend easily
