Updated STC and still long crank!
Looking for some insight...
Last week I did a lot of preventative work hoping it would cure my occasional long crank issue. I updated my STC, Standpipes and dummy plugs, and replaced the o-rings and seals, and polished the spool valves on all 8 injectors. In the last 4K miles I have also replaced my oil cooler, egr cooler with the bulletproof one, and the IPR (because I let trash go through it when changind my oil cooler).
Some of my starts are 1-1.5 seconds. Most are 2-3 seconds, and sometimes (usually when warm) I get over 5 seconds.
My ICP climbs to well over 500 as soon as I start cranking, my fuel pressure is in the 60s, I have new batteries that are usually around 12.2-12.5 when the glow plugs are on and recover to 13.2 after they turn off.
FICM never drops below 46.
I'm running 5w-40 full synthetic Schaeffer oil with about 3000 miles on it and an oil analysis just done that says I have plenty of life left in it.
New Racor fuel and oil filters at last oil change 3K miles ago.
Running great and always starts eventually, but it's got me worried...
