The damage from Sunday

[discostu]

Number 3 piston has totally destroyed itself, how exactly im not sure.

removed the head earlier to find this:









will remove the sump tomoz and will probably find the piston living there in a few thousand pieces.

unbelievably the gudgeon pin was still in the conrod

Unbelievable!!!

Unlucky mate. Presumably the liner gave up allowing the piston to slap about...but for it to have completely disintegrated is incredible. whatever isn't in the sump must be in the cooling system.

A short wake was held for the engine

Bit of araldite will fix that. Seriously though, sorry to hear about the failure, it looks pretty terminal.

There are soooo many captions to put to that pic

Look on the bright side, I left home this morning 200 yards from my house there is a righthand bend and as I rounded it I was greated by a pair of deep furrows in the verge and a white peugeot resting at 45 degrees to the horizontal against a large tree!
The car was facing me but had definitely be going from my direction so not exactly sure how it managed a 180. This is the 2nd time in the last 6 weeks that the same tree has had a fight with a car a both times the car lost. Driver was okay.

well although bad and it sucks to have to wait so long for the AA - atleast your in one piece - could have happened going into a corner and... well could have ended up at the bottom of the mountain!

Matt... are u looking at my arse?

[sorrento205]

hmmm, ive had my detective hat on all night and ive come up with 3 possible explanations, although i'm by no means an expert, just possibilities that entered the vast cavity known as my head.

1. Ingress of debris through inlet system - air filter to blame?

2. Failure of spark plug, i.e. electrode prong breaking up and falling into the combustion cycle.

3. Mechanical failure of either Piston or Liner (more likely), especially if say the rings werent quite happy and you were getting piston slap?



What does Dr Mikey G think?

[Mikey G]

I have to have another look at the liner as the more i think about it it looks like it has failed on a hairline crack somewhere causing water ingress into the cylinder resulting in the cylinder to hydraulic destroying the piston and remaining liner in the process. It is strange that there is absolutly no sign of the piston or the missing side of the liner to be seen, only the bits coming out of the exhaust...

Definatly a was now

Its been on the 405 engine since july last year

I think he has other plans now, 2 litre turbo is an option for an easy 200bhp, he aint having my engine lol

[discostu]

Just to keep u uptdated, i found my piston last nite. here it is:





May have got my hands on a new engine aswell, so things are looking up

[2DOGS]

Wow

You'd never think those big lumps would have got through.

[AR]

Sorry to hear about your problems mate, but happy to hear that you got a new engone.

Cheers,

Hope you have better luck with the donor engine. Never seen a liner go like that though was you pushing it?

Only 7500 rpm, the pushing came after it stopped
