Default Question about NF engine code...

I know that the NF came in the 5000 86-88. Then it came later in the 100 with a different two piece IM. My question is are the oil squirters present in both blocks, or is the block in the 100 actually an NG block? I'm trying to source a long NF Block for a 4KQ but I'm not sure where to look.

Default to answer your questions: yes and yes....

they both have squirters and the NG came in the "100" and "90"

Default Tidbit about the squirters

Plan on replacing them unless the engine is uber-clean inside. My donor had several coked shut. They aren't cheap either.

Default Are they still easily available?

I found an NF short block for 365.00 out of a 5000. Seems reasonable to me vs. 650.00 for a 2.5L Eurovan (short).

Default You don't have to replace them...

All they are is a spring-loaded ball-style check valve. Clean them up with carb cleaner and make sure the ball moves freely if you can.
