I'm looking at upgrading to con rods that do not have the oil spray hole. Is it required to run con rod bearings that also do not have the oil spray hole? I currently have a new set of bearings that have the hole and wondering if they are compatible.

Thanks

Dave

The hole doesnt matter if it's not used.
Most aftermarket rod bearings have a hole in top and bottom bearing shell (so they're easier to manufacture) the one on the rod cap is blanked off by the cap.
If your passive squirters hole isn't there, what are you using for rod pin lubrication?

I'm not running these yet, still researching. It sounds like others that run without this sprayer are content with the amount of oil being flung around from windage spray.

Hi,

Renault Clio 172 ones are good fit to our engine.
They are handed but you can buy them for £10 each.

Here you can see mine fitted.

Fitting cost was £60 due to depth of drilling which I didn't have.
It is press fit. 10.1mm is the size and may need to drill it to 10mm then press fit.

Cheers
Atchi

Thanks for the info mini. I ended up having a local machine shop drill the holes identical to the stock rods. How is the clearance with those squirters and the crank counterbalances? Looks tight.

It is good.
I had 5 different sets checked.
This Renault set is only one I can use without worry.

I had 2 different sets from Nissan, BMW, VW and Renault.

Good job 2 sets were free!

hi mate ,
i had the same problem with my first build with forged con rods i drill them in as well , had mixed views as well . thought it was important for lub on the thrust side of the cylinder . still not sure whether to do it again on my current build .

Oil squirters are to keep piston crowns cool
Not purely for lubrication (it's a temperature assisting mod to reduce detonation)
