Hi
is it a worth while mod to use the Cosworth oil pump and pickup pipe with the spray jets ( bottom of pistons ) into a hot pinto engine
or will it affect oil flow in other areas like cam spray bar

Pinto rods have oil jets already squirting at the piston don’t they ?
Cosworth ones don’t hence the spray bar

I did a rather complicated Cosworth spraybar addition to an RS2000 oil pickup because I had fitted Cosworth rods to a fast Pinto. I then found out you could just notch the rods to get a similar effect, I’m not sure if the crank scraper I fitted would negate the notch option
yes i did type it right, the cosworth spray bar is all about piston cooling, if you dont have the extreme heat of a turbo you dont need it whatever sort of rods you have. theer have been a zillion engines built with nothing, it doesnt hurt, but if you must you can file a notch in the rod to help deflect oil up.
below is a picture of a factory bmw rod with a notch as it came from the factory
