I have pay pal or check is fine,
919 698 6613
Now I have come to a 'now what' scenario and have done lots of reading , heres where I am at..
Running on diesel for all tuning
Injectors set properly
New timing belt
500 miles on fuel, air, and oil filters
Air intake system is pieced together because of rodent damage. I tried to mimic the stock setup with other things around my garage, I took the square air box out do to a hole being chewed in it(its possably repairable).How important is the exact shape of this system compared to he importance of overall length of the system.I cant remember the number of inches its supposed to be exactly.
CSD has not worked since I bought the truck. I have had to hold the pedal down a bit for a minute for my cold starts. CSD is still in place as a whole unit.
I don't have a temp. gun , tachometer , a dial indicater or an extensive diesel knowledge.
My first impression of the sound with the properly set injectors was that it sounded like it was popping a little harder at idle. When I drove it though I started freaking out a little bit climbing a hill nearby , it just seemed too noisy like I had a lifter ticking when the rpm's went up.
After a bunch of reading I wonder if my bad CSD is keeping my timing from advancing at higher rpm's and to me disabling the CSD would be my next step on path to super tuning. On the other hand I keep eyeballing the injection pump and get tempted to adjust it..I don't know whether its ever been moved.
I have an injection pump on the shelf with a CSD on it that looks like it has never leaked but from what I have read it is all but impossible to replace a CSD while the pump is on the truck,and why would I swap them if they go bad like they do?
I am going to test for a set of balanced glow plugs to get started.
Thank you , nate
Now, the fact that you now are having a crisp "diesel rattle" is a very good thing and the fact that I can now hear it at higher rpms is also a good thing..............now in theory, we should hear the same diesel rattle at all rpms with any kind of fuel (provided with have tuned for that fuel), but our IP's are limited to proper timing advance at about 22-2500 rpm's.
The Next thing is you do not change a thing until you do a glow plug reading ( balance them out).........if you start with a balanced set of glow plugs, then you can even adjust the intake snorkel length with a basis for better or worse...........
Ok, after the engine is hot, turn the engine off, crank with out many rpm's, take a reading at idle, then rev the engine up a few times above about 1800 rpms, then let it idle, the readings should now be lower than the first reading if the CSD is working.
lets us know your readings
Snorkle length... something I am now curious about.
I have an 81 PuP and i removed the box and hoses for the intake. Wanted some more room in the engine compartment.
Did I mess up by doing this??
I had no idea. My thought (wrong?) was a shorted length intake would allow the engine to breath more easily.
cylinder at startup after revving
With the bus bar hooked backup to all four
I thought since the numbers went down with the bus bar installed maybe my ground changed a little for some reason. Not sure. I was grounded to one of the valve cover bolts and I'm using a Gardner Bender multimeter with a new battery with some longer leads on it for later . So it appears to me the CSD is working as it has an effect on the GP readings,but not working enough to keep the motor running on cold starts in cold weather. I'm going to measure my snorkle . Thanks for the help
Regarding the Snorkle.
Is it the length, the shape or a combination of both that should be"tuned".
Nate, have you checked your fast idle to see if it is working?
Glow plug readings: 1.8 reading at idle is pretty good now, you need to get a reading on flat ground (very constant speed)at 55 MPH in fifth or 45 in fourth.. theses are the readings that you want to work with.......the objective is to get the lowest reading at high way speed........readings under 1.5 are excellent...............
please keep updating your findings,
