Been a bit since I was on. Work, and the winter of discontent just won't stop. It's almost April, and I have 3 feet of hard pack snow out back that all 198lbs of me can walk on.
I have searched for my symptoms before posting on here, to no avail...
Last time i was on, I had just finished a project where I and some other folks here came up with a circuit diagram design to put a thermostat relay on the GPC to limit glow plug heat-up to only when the block (coolant really...) was cold. Long story short, that all works fine. Tested many times since...
While doing this, I also did: returns, orings, gp's, harness, and new champion radiator install. All good. oh... and a gear reduction starter. (man, do they make a difference!)
Recently, and with increasing intensity as time goes on..., I get the sputter and cloud that the air was giving me before, but the symptoms have changed. When it was the returns leaking, the sputter was VERY time sensitive. Overnight would be a starting issue every time gp's or not, but 5 min in the store and a restart would go fine. Diagnosis: slow air intrusion.
Now it's different...
I can leave it overnight, and she fires RIGHT up every time now (even in -15 with no block heater... thank you BERU!), but seems to have a large bubble of air somewhere that gets to the injectors after prime is used. I suspected at first it's pre-filterhead air... Now not so sure, since I put clear tubing from filter to cap #.... uh... the one with the rotunda... and another clear line from the frontmost driverside cap into the IP. When I crank, these two clear lines stay full of fuel the entire time, every time...... and I just don't ever see air in them EVER.
Also, I can go in to a store for LITERALLY a minute or two, come back out, and when I start her up... there's that smoke!!! But if it was a minute or two, a couple revvs, and she's not smoking any more.... So basically, the air is getting in quick, but only so much gets in, and then the process stops it seems...
Which leads to the part I'm dreading: From what I have read, I have gleaned this: IP's have a shelf life of about 130k with decent use... I'm at 165k on the original IP... Also, there was a period right AFTER I did all that work, and BEFORE I started using the highly recommended Stanadyne blue bottle additive where this issue was minimal if not non existent...
So yeah....., my theory: the Standyne detergent in the blue formula cleaned the **** out of my overdue IP, possibly removing deposits from somewhere where they were doing something good: keeping air out of my IP.
Before I go asking a ton of random follow-ups as I work this out, I'll just ask one: does this sound correct/possible?
I don't want to do the IP if i can help it...
Oh yeah.... one more symptom i noticed: after full warm up, i give her a couple good revvs almost to redline, and on the stomp... a little black, but when I let off, as soon as the rpms peak, and start to go down...... a little PUFF of white/blue smoke! EVERY TIME. Right at the top of the revv, no matter where on the rpm band I go to....
As always, thanks in advance...
