Con rods

November 15, 2008, 05:25:40 PM

Can anybody confirm that the con rods used in the 2.2 are in fact the same as used in the pug 505 turbo?

They sure as hell look to be exactly the same....

I can't translate "con rods" into French, it's what? a photograph or a drawing

Hi Philippe,

Con rod may be "la bielle"

A very nice place to look for translations is:

In the documentation Peugeot for engine 9N2 (murena/tagora) & N9T ( E ) (505 turbo) a difference between:
- Pistons
- guide of valves
- exhaust valves

But no differences for connecting rods

I don't suspect that many parts for these engines are..

Just to wrap this up..
The connecting rods are NOT the same. The turbo rods have small holes on to allow oil to spray onto the underside of he pistons.
I'm not certain that this feature is present on ALL 505 turbo engines though.

Anything for you Anders

They appear to be identical apart from the oil channel, so my guess it that they are of similar strength.

Interesting to see. Quite a small hole... It must be spraying the cylinder wall more than the piston. It could be giving better lubrication of the piston rings to allow for higher combustion pressure?

I don't think so.
There is an insert directing the spray straight upwards. And in either case if better lubrication of the cylinder wall is wanted (which I haven't heard should be a problem on Murena engines) there are better ways to accomplish this.

Why then only spraying on one side of the piston? Why not both?
