ok so nobody can tell if the delco glow plugs swell up

[brent64505]

come on guys some body knows if the delco glow plugs swell up if they get over heated or if the controller sticks

On the "other" site, several said they had them swell. I've never used them, so I can't give you a definite, just that many "over there" said they had them swell. IIRC, they weren't as bad as autolites, but had issues as well.

Yes they do. I have a 6.9 in the shed with 5 AC plugs still stuck in the heads. I got one out and 2 others are Bosch, also stuck.

what delco plug? The newest AC60g wont swell. The older 9g will and so will the 11g.

the nice thing with these Detroit Diesels are thet if the glow plug breaks and falls into the pre-cumbustion chamber you can fish it out threw the injector hole

yep, they sure will. usually timing and or fueling related. I've got about 5 sets of them that are melted off, good thing I save all the old good ones out of core motors! The 60g is still the best plug IMO, the wellmans I tried were worse.

The last set I got from them were the Wellman brand, not as good IMO.
