Testing glowplug pigtail

Hard white smoke starts. Tested the glow plugs threw the valve cover harness and have 2 that are infinite..rest are in the 1.2 ohm range. Is there a way to test the pigtail back to fix issues that way, while im at it. Thanks.

If you're talking about the pigtail between the GPR and the VC connector, just a continuity test would do it.

To get any further to tell whether it's a bad glow plug or a disconnected or broken wire in the UVCH, you'll need to pull the valve cover off. You already know that there's an issue there. Once you have the VC off, test the GP's directly for resistance. If they all test good, then your issue was the UVCH.

Since you know you have 2 dead plugs, your going in anyway. 2 dead is totally enough to make it smoke when cold. Mine is hard to start if 2 are dead. I know cause I have 2 that wont stay plugged in, keeps popping off the plug, and there so fragile I don't want to try and tighten the clip. So I glued it. Lol. The harness can be tested without taking the cover off, if the plugs are plugged in. lol. The procedure is in the service manual and tests all the wires. If you need a harness, don't buy the after market, they are garbage, and most times the gasket part of it is off and they don't seal properly causeing leaks. Tried most of them, none are any good unless you goop them. Plugs are cheap, if your going in. replace them all.

Rather than start a new thread I'll just dog pile on here...lol
Only 1 ohmed out over 13, so I'm going in.
Do you really need to remove the CCV 'dog house' to remove the driver side valve cover? I've seen it both ways on the interwebs.
And if so, do you need the (4?) OEM style O-rings which may be all squashed, or can you just use some the right size?


Thanks in advance.

I've done it both ways. No need to remove the doghouse. It makes a handy "handle" for the valve cover.
If your doghouse isn't leaking around the o-rings or at the screws, leave them along. The larger ones are triangular cross section o-rings, not normal round ones, so if you do replace them, get the correct ones, which the ones you linked to appear to be.

I didn't notice any leaking from that area, or any area at all, but I'll double check. Thanks again.

So I got the glow plugs torqued and connected, but still need to ohm them out before putting everything back together.
Question about the oil around the old glow plugs. I removed some of it before pulling them out but apparently not all of it. Is it bad to try and start it up this way or should I rotate the engine with plugs out first to push oil out?

I don't believe there's enough oil to lock the engine up, but I would at least rotate the engine 2 full turns by hand before attempting to start. I wouldn't bother taking the glow plugs back out. As long as the engine rotates freely by hand, it will start and burn off any oil that's in the cylinders. Probably don't have mosquitoes this time of year, but it's good repellent.
