lots of smoke out driver side exhaust on startup

[84cucv1ton]

good morning. Just realizes the other day. Truck starts pretty good. Glow plugs are about a year and a half old. Injection pump has three or 4000 miles on it. Injectors have maybe 1000 miles on them. Passenger-side exhaust has just about no smoke. Any ideas? Thanks

Bad glow plug. Did you use welmans?

 

[84cucv1ton]

i will check.. not sure what i used on this truck..

 

[84cucv1ton]

autolite plugs.. going to order ac60. hope they get here fast

 

[WARWAG]

cycle your glow plugs twice.

 

[84cucv1ton]

yes i h ave learned that with those plugs.. have yet to have one swell up.. seem to be a good plug for 68 bucks

 

[ranchhopper]

Like stated above a bad GP or two mine did that with two dead GPs on the same side.

 

[84cucv1ton]

so i have a had good luck with the ac60s.. is there any other plugs to try?

 

[84cucv1ton]

anyone?

 

[dstang97]

60's are the best

I have had Ag60G's in for over 2 years with no problems. I did bypass to the 12V terminal.

I had the same thing happening, when i checked it out a glow plug wire had wiggled off rear glow plug drivers side.fixed connector and plugged it back in, no more white smoke cold.

The connectors are the weak point of the system. They are brass or some other copper alloy and eventually lose their tension. Dirt can enter, causing higher resistance which causes heat and starts the vicious cycle.

The blocks can be taken off the connectors with a small awl, then the dirt can be positively removed. Restore the clamping tension by carefully bending the connector, then reassemble.

I use ac60 glow plugs. I have a manual glowplug switch and i cycle them twice for ten seconds each with a 5 second break in between.

I've used AC60's with great success for 8 years, on my second set. With the AC60's you can burn them for a full 20 seconds, withought the 5 second delay. Thats when they reach their maximum temperature of 1851 degrees centigrade. Though I find 17 seconds is enough on the coldest days. I do use a shorter time with a 5-10 second delay between burns during the afterglow cycle. I think the old school plugs (AC13,11,9 etc..) were the ones which would swell easily so thats where the pause between cycles would be warranted. Here's the temp charts for your perusal.

 

[scottladdy]

Hadsrubal, Can you post pdf's of those charts? It would be greatly appreciated if so.

Happiest of New Years!

Don't have it in PDF form, just in 1MB bmp's, 546 by 697.

I recall a conversation with Doghead a couple yrs back about all of this. He spent alot of time researching, phone calling with reps ect.. maybe someone can find a link
