About three years ago, when uhaul was clearing out all their stock, I bought a set of glowplugs from them on ebay. I thought u haul only used motorcraft plugs, so I didn't care that the brand was not listed in the ad.
When they arrived I saw that they were Delphi brand so I got on here and began to search to see if anyone had used them. I didn't find anything, and knowing that other delphi parts had been good for me, I put them in my 94 f-250.
Fast forward to last week, all glow plugs were dead so I began to change them out with motorcraft.
Three of the 8 came out without their tips and the other five were swelled and about to go.
In retrospect, I should have bumped the motor over to see if I could blow the tips out. I did not.
When I started the truck after replacing the plugs it sounded awful. Knocking loudly at idle and through the rpm range. It quieted down after a couple minutes but retained a tick that was noticable from 1500 RPMs up and got louder with RPM.
I drove it that way about 15 minutes to see if it would clear. It did not.
My thought was that a valve had been damaged by the tip and I was not pleased. I walked away from the truck and let it sit for a week while I mentally prepared myself to get into the top end of what had been the best running IDI I have on the lot.
Yesterday I had to drive the truck another 20 miles. About 3 miles into my trip the truck started clattering and popping in the motor. Lasted about 5 seconds.
Now the tick is gone and the motor sounds just like it used to.
The purpose of this thread is to 1. make sure everyone knows that Delphi glowplugs are not much better than autolites. 2. Put out there that nasty sounding ticks from glow plug tips can get better. I couldn't find either of those tidbits using the search function.
Thanks for listening.
