What should he do? legal question engine dead due to workshop

[edo]

Ive just noted...stock engine, external wastegate...

[[ryan]]

Could be a 2J?

[edo]

Could be, but given he said it was an SR I reckon it might be that.

[[ryan]]

Missed that... stock SR + ext gate is interesting!

sr20det - td06-19c, yes fair enough the engine was stock, injectors were larger items, car had a larger fuel pump, fmic, everything it needed to run. even the tune was set for apparently more fuel up top, ignition pulled out.

now the engines bearings are dead, yep fair enough but hes now trying to put it back on the customer that its his fault not the workshops. my friend is happy (well no hes not) to pay for the bearings. and they do the labour for free, but no hes saying that it wasnt there fault. he can get the bearings for cost and he has to help them pull the engine out and pay for the bearings to be replaced

Name the workshop. Or at least PM me :D

[edo]

Sounds to me like he might take this opportunity to use some better rods so that all that bolt on stuff has a chance to get used.

I reckon your mate is going to struggle to push the point.

PM me too!

There is some risk in putting a engine on a dyno, its not exactly being kind to it. Sounds like the engine was ready to go, boring the crap out of it on the dyno did it. Sad to say shit happens.

Whats the history of the motor?

i would rather he gets this problem solved civily rather than throw up a slander case as well.

[TonyJZX]

i dunno - sr20s do throw a wobbly without any warning as nissans are wont to do

[edo]

SRs have some valve train issues with big revs but thats about it...excluding things that people do to wreck them

They arent going to fix it for free. There is no way to prove it was the tuners fault.

It might have been the engine's time to go.

SR20's are notorious for shitting bearings if the tune isn't spot on, even mild detonation will kill them over time, and bad detonation is enough to hammer a bearing/smash a ring land very quickly..

if its tanked a bearing, im almost willing to bet that its shat a land as well, do a leak down and compression test on it..

How many of the tuners here use knock detection gear, like the carman headphones, or the HKS knock amp?.. from the sounds of it, the tuner in htis case didn't as they had a lakcy listening to it, which is all well and good for the audible detonation, but low down detonation that isn't overly audible when theres a heap of noise going on, and something you definately won't hear out on the street will pound out a bearing the same..

as for claiming it, you'd have to do a tear down on the motor and check everything thoroughly, if its had bad detonation, the pistons will have noticeable det marks/broken ring lands..

it could also be oil starvation, which SR's also suffer from, but unless they where belting it sideways on the road test id point more at detonation..

that said, it could have already been on its way and just happened to be audible after the workshop had it for a 'tune'

tear it down and see..

As I said, when someone does something to wreck it.

Don't like your chances you'd have to prove that they blew it up due to incompentence. I would suggest to your friend that if the couldn't do that right (or at least there are severe doubts to their ability) that he find someone else to pull the motor apart.
