Concur........No Porting....rubber tubing looks like new PCV connector.....just squeeze the fitting into the rubber tubing.....same with that rubber connector on two PCV valves.
Since you have it this far......remove coils and recondition the Starter Solenoid as well as the Valley Drain. Look for oil leaks........ and loose connectors on vacuum system. Tighten bolts or re-install bolts on Crankcase Cover and check all Injector Housing Bolts....re-installing any that are loose with blue Loctite. Basically......do a Top End Reconditioning.

Yep, replaced coil packs, checked vacuum lines, and drain. Solenoid is next up. The runners are measuring around 35mm and the inj housing are all around 36 mm. Isnt stock just about 33mm? Sent from my iPhone using ZR-1 Net Registry After looking at pictures of actual ported inj housings and runner theres no way my measurements are accurate LOL Last edited by 1991KOTH; 05-06-2017 at 09:59 PM. |

In your last photo it appears the hose for your dual PCV valves is torn? Hard to tell but maybe why not aligning to pipe?

Injectors look like FIC stainless. Coils were accel? IF that tubing is very tight thats better. Dont want any leaks from there so force the pcv line into the fitting !
