Big End Knock After Storage

[merlins_hat]

So I pulled my 182 out of storage this weekend. Did some checks and fired up. All seemed OK.
Went for a short drive and after a while I could hear a knock on overrun.
Pretty sure its the big ends

Question is how big of a job is it to replace? Can it be done with the engine in situ or does it need to come out to do it?

I should also say, after the drive, the oil level warning comes on on ignition.
And the engine has done 130k

You wanna be more concerned with why the big ends have failed.

Just slapping a new set of shells in the engine won't do you much good if they get messed up just like the last set.

I know. And thats a secondary question.
I imagine its run dry, parked on a slope, a year of trackdays and low oil level all culminating in a bad situation.

But can they be replaced without pulling the whole engine out?

Surely you can just tap your wand on the roof and wiggle your nose?



Ps - engine out, tear down and inspect crank. Did you check oil level before setting off?

If your a right pikey with it you can lower subframe, remove sump I'm situ and slap new shells in, admittedly now I've written that it does sound tempting even to me over pulling the engine out and apart.

 

[R3k1355]

It's a gamble, cos if you get the cap off and see any damage to the crank then it's coming out.

What's a used engine go for these days? Might be worth slinging a working engine in while you rebuild the other?

Engine out and rebuild it properly, or do it twice.

 

[Robbie Corbett]

Engine out and rebuild it properly, or sell it immediately after.

Engine out and rebuild it properly, or do it twice.

This.

Bearing material will be everywhere now.

Will need oil pump cleaning out, if not a new one tbh.
