It's been 11 days since I finally got the engine back up and running. So far the engine idle is smoother now and has a quicker throttle response.
Before my top end rebuild the Nanocom showed an average 3.87 of Roughness/0 Misfires for all 8 cylinders. After the rebuild it now shows on the Nanocom an average of 1.3 Roughness/0 Misfires on all 8 cylinders. I guess it’s all a combination of new fuel injectors, new HT Taylor 409 10mm leads, new spark plugs and new coils on a 19 year old V8 engine.
I'm going to drive it for 200 miles and then retorque all the top engine bolts and park plugs just for piece of mind.
As far as the heavier aluminum SAI tubing, I replaced it with 2 meters (I didn't use all of it) of 3/4" red silicone tubing and a "T" fitting. Adding this will make it sooooooooo much easier to remove and install if need be for top rear engine maintenance.
It hasn't been cold enough to properly test out the SAI pump and tubing. I will look for the wiring and try to add 12VDC to turn the pump on to ops check it.
I finally replaced the four worn tie rod boots on the Terrafirma drag link and track rod with the polyurethane boots from Gwyn Lewis UK. Hopefully they will last longer than 6 months like the Terrafirma boots did.
