Hi, new member here, just wondering if anyone knows the torque setting for the connecting rod bolts for a Mk2 Punto? I've recently swapped mine out as they were real bad. Thankyou, and hope to see you at events in the future

Do you really mean the bolts on the connecting rods? The connecting rods between piston and crankshaft, inside the engine? These are known as the big-end bolts, being on the big end of the con-rod. How did you know "they were real bad", and what else might be affected?

If this is what you mean, and you have a 1.1 or 1.2 8v petrol engine, the big-end bolts are tightened first to 20Nm, then angle-tightened 40 degrees. Seems to be the same for the 1.3 multijet diesel. These taken from the Panda manual, but should not be different when fitted to other vehicles.

If you are talking about something else, you'll need to be clearer.

Id assume connecting rods he means yes conrods and usualky small ends are oush fit and big ends only one with bolts

Im will bill here
As for the bolts were real bad? Badly what? Rusty? Rounded
99% of 1.2 8v will never have had them touched since factory...

I would also generally refer to them as con rods, I would differentiate between big end and small end bearings, never came across small end bolts though. The journal bearings are the others. I do wonder what is/was wrong with the original ones as well.

How the hell did he know? Just popped the sump off on a whim, just to check?

I think we'll get a different story when he returns, maybe anti-roll bar links? Guesses on a postcard? First correct answer drawn wins.....?

track rod ends

Wiper linkage?

Or maybe, just maybe, looking at his avatar, his Punto temporarily parted company with its engine.

Has it crossed your minds that the rods or the bearings themselves might be the bits that were bad - which is how I read it?

All he's asking for is a torque setting, no need to take the attitude that newbie = clueless idiot when he's given you no cause to, which is the direction this thread seems to be heading in IMO.

From my mk2 Punto manual:

1242 8v and 16v big end bearing cap bolts - 20Nm and tighten a further 40 degrees (as per post 2).

Afraid I don't have HGT / JTD specs.

Sorry for not being clearer haha, yea, I meant the bearings were bad, and didn't know the specs of tightening the bolts back up

By the looks of things I might need a new crankshaft though as cyclinder 2 connection seems to be scored,

You could probably get the crank reground then fit over sized shell bearings. It'd be worth it now you've got it all apart. Id check the rest of the engine i.e. bores etc first though.

Will check them over, cheers, push comes to shove i can get another crankshaft from local scrappy, easy enough to get out,

If the engines already seperated then yes it wont be too hard...
But if its still in the vehicle then its a geabox and flywheel out to stand a chance of getting the crank out...

Lots of labour....
Tbh id look at fitting a good 2nd hand engine

Ziggy

It was a 2nd hand engine haha [emoji23] was told it was good,but I was proven wrong lol. Hence all the rebuilding, I will get there, I've got a lot of people to prove wrong,

Replacement engine might be a good option, if from a known source, or comes with some sort of guarantee. Unless this has done mega miles, that bearing looks like it has been a stranger to oil for a while. So why no oil? That needs to be fixed.

I'll try book some time off work and get it done, morning til night, as I don't have an engine crane (we lifted it in with an old seatbelt) ((bring on the haters haha)) but the car means too much to get rid of, I will have it running my old focus got written off (through no fault of my own) in November, so I've not driven since, so I'm determined,

I've no idea, the engine wasn't mine, so not sure on the history of it,
