I love how good everything looks and you’re doing a GREAT JOB Bad 81!
I am trying for sure. The only minus is, I still feel them shakes! Like
@The Sphynx mentioned.
So the left side looking at the engine from the radiator has them hoses renewed August-September 24. Bypass, supercharger, oil separator - before MAF - call them working as new tight, operational…
Right side - after MAF - throttle (with 2 vacuum lines), intake, with the PCV cleaned and new tight hoses, new intake Elring rubbers (originals good as NEW) right… still them low rpm shakes.
The only thing I have seen recently is oil leak on the oil level sensor, probably the O-ring of that OilLevel sensor.
And I am out of ideas…
On the PCV foot, them 2 small brass…things were well stuck - like the dark brownxxxxxxxxx suggested and using clear hose, shell 99+ whatever higher grade fuel they have, cleared it until the following experiment was successful. The small 10-15” hose was attached under (where the hose for the PCV valve should be) and filled with petrol, then the loose end was raised above the brass check valve level and a fountain of brown xxxxxxx and petrol leaked out! Multiple times until clear fuel was seen.
Done on both sides 12 and 34 cylinders. So the suggestion of “unmonitored“ intake air…is kinda I really mean it unreasonable.
The PCV valve itself had been soaked, pressure washed, soaked, shaked….whatever you name it multiple times until clear petrol and/or brake cleaner leaked out both ways.
I am considering propane can and long hose as a reach-in tool under the throttle body, as the assembly is metal/alloy body getting into plastic intake relying on o-ring. Age related marking, cracks, etc…were not seen, but still, open box phenomenon ( it looks well and nothing to be called disturbing) vs assembled and still xxxxxxx results.
Any next step on your end?
