what do yall think
Well there was talk on oil burners a while back about deleting glow plugs in ability to lower compression and make it to were you can run higher timing which helps to a point in making more power, well i took an old set of glow plugs and cut the tips off so it was just like a pipe plug or something and i put them in, only down fall is it wont crank, well there has been talk of an air intake heater, i figured sooner or later i would try to rig one up, but for now i crank her with a little wiff of the bad stuff, well as of now i have the timing advanced as far as i can turn it till my injection lines are bound up to were it wont go any farther, i have new injectors and a rebuilt ip when i started i could come over the mountain at about 50(7% 3 mile long grade) well after i advanced the timing way up right now its almost to were it sounds like a psd but not quite there yet, i have been able to come over the mountain almost pushing 70 mph, i have done lots of timing adjustments on it and right now it seems the best so far with the timing way advanced the way it is,
Now i have a question, is there any way i can make the timing go any higher so i can see if i even get more power or less? cause right now i cant turn the pump no more, and o yea i forgot to mention the truck doesnt have a turbo! its n/a and it has a crap load of power

Do you have any slot left?
If the injection lines are binding you up, you can loosen the injection lines on the IP and turn it farther as long as you have slot left on the IP.
If you are out of slot, then timing gear a tooth off is the only way to go farther.
I must be missing something in the no glowplug, lower compression ratio, advanced timing thinking though.

im not sure i will have to check and see if i have more slot left, ok the thing on the glow plugs is everyone has always told me too advnced timing will eat them, well if you cut tips off flush its like just having a plain ole pipe plug in there, well that also lower compression ratio some doesnt it? since thats something less in the combustion chamber to take up space, i guess if you knew how you could figure out how much it did lower, the thing about advanced timing is, every little bit i bumped the timing up on my motor the more power i keep getting, so i figued i will keep turning it up till i find the most power or something catastophic happens one, so we will see. whats your thoughts on all this dave?

I have a set of cool wrenches that have the opening turned 90 degrees from the handle that can get to them, but without them remove the lines above them is about the only way.
If you go to far, you will start combustion while the piston is still traveling up, and that will be hard on the rod bearings.

If i get there far power will start to go the other way wont it? and can you take a pic of them wrenches and post them im interested in seeing them

I will try to remember to take a picture tomorrow.
I would look them up online, but I can't remember the name.
Here is something close at Sears.
Armstrong 7 pc. Full Polish 15 and 60 degree angle Wrench Set Inch
Here is another one, closer to what I have but the sizes are not right.
Armstrong 9 pc. Full Polish 15 and 80 Miniature angle Wrench Set Inch
Sears Item# 00999281000 | Model# 27-885

starting fluid, but im looking to adapt a grid heater in if anyone has a good one that they would part with for the cost of shipping of fairly cheap

If you are plowing this winter, you may want to get the glow plug system in shape.
Sudden storms that were not supposed to drop anything have a way of sneaking up on you and you have to roll out with the plow when you had not planned on it.
15 degrees with the wind blowing and several inches of snow on the ground waiting on the block heater seems like an eternity.
Or even worse, big heavy snow fall and the power goes out, and you know all of your snow customers will be mad if the lots are not cleaned.
Miss one time plowing and you probably just lost customers.

I am not sure how advancing timing on a diesel works but from what I can gather cutting the glow plugs off makes no difference. Advancing the timing will make more power to a point but it will also make more heat. This is what kills the glowplugs so if you already dont care about the plugs them let them die and keep your compresion ratio while still advancing the timing. Then watch the temps and when you get a good balance of power/cylinder temps I would think you were at maximum gain.

I understand where he is going with the thought about removing the glow plugs to lower the compression.
6.9 precombustion chamber volume is 18.34 cubic centimeters.
Without doing some serious calculations, no glow plugs would probably add 2 more cc's, which would lower the compression ratio a little.
But if you have enough heat to melt the glow plugs, you are probably also doing damage to the aluminum pistons.
And that small amount of extra volume is not going to make much difference in the cylinder pressure when the fuel ignites, which is what I meant when I said I was missing something on that train of though.
