Hello All,
Last week before my new radiator arrived I was out and about when the engine temp started to climb. I pulled over to cool down. When I restarted the car the check engine light came on with the error code P1316. Aside from that I now have a ticking sound, and the car doesn?t sound happy

I just did these today:
New Spark Plugs .035 Gap
New Plug Wires
A bottle Techron
Cleaned MAF
Changed the oil
Changed transmission fluid

I Cleared the engine code and it hasn't returned, but the car is running rough. It stalled a few times.
What am I missing now?
What should I be looking for?

Thanks in advance!

rough running and a 1316 makes me wonder about the plugs/wires more than the overheating. I would check to make sure the wires are routed correctly and that they are seated correctly as well.

So I checked the plugwires and everything seemed fine.
I too kit out for a test drive and it started running more rough after 10 minutes. The engine temp began to climb so I pulled over and noticed that plug wires #1 and #3 had popped off the spark plug. Re-seated the plug wires to the spark plugs and it started up but still rough, while giving only the P1316 error code. Felt like the engine was going to stall and it did a couple if times going home. I also noticed that if the truck comes to an abrupt stop it would stall out.

The new plug wires are from KOI and for the D1.
Think I need to get another set of plug wires?

Thanks

I would start there... especially if wires are just popping off.

Champion Plugs?

I've run AutoLite on my D1 along with Champion and haven't noticed any difference.

The Champion plug tolerances were set up for the d1. The Autolite plug is a true hit or miss. I would of told him to toss Bosch plugs, NTK etc on that vehicle.

The champion has proven itself to be a great plug on the d1 for over 20 years now...


I would leave the Champions in and look at those wires first.

Did the ticking sound begin after a) the over-heat or after b) you swapped plugs.? if b, check the #8 plug (passenger side closest to the firewall). That plug can be difficult to seat properly if you don't have the right socket. The exhaust manifold can get in the way.

I've never heard anything bad about the Champs so if you're troubleshooting that'd probably be the way to go.

I got STI plug wires in route. Until than I took off the new KOI plugs.

I checked plug #8 and it seemed seated properly.
Plug #5 and #7 are a pains in the butt to access.

To anyone reading this post be very cautious and do not get these 7mm plugs from KOI.

A simple tug and they can be pulled apart. I was surprised how thin the wire is inside, and yet it is still coated in another black insulation

Thanks

**UPDATE**
The new plugs are scheduled for tomorrow.
I drove two miles from home and the car stalled and simply stopped. I couldn't get it started, engine wouldn't turn over. Fully charged dual batteries and it didn't click or anything, just a tiny vibration in the moment of turning the key.

Had the truck towed back home...

Help Help
What should I now be looking for now?
Help

​​​​​​​Thanks

Plug wires arrived a few minutes ago.
They feel like quality and the weight is much more than the crap I previously posted.
As mentioned the Rover was towed home yesterday with a no crank condition...

Thanks for the response!
I took another image of the plug hole, I stuck a small metal rod beyond the threads and felt something in there that could bump into the plug

Yikes is right! Can you tell if there is a foreign object in the cylinder? Like if you shove a probe in there, can you feel anything loose moving around? Maybe turn the crank a bit so the cylinder in that piston drops down a little? If you can fix a magnet to a piece of wire and lower it through the plug hole, perhaps you can retrieve anything small enough to pass back through the hole. Assuming it's ferrous and that there is actually something in there, which is all speculation.

One of my greatest fears during the head gasket job was dropping stuff into the engine during reassembly. Despite using masking tape and rags to cover all points of entry, I still managed to drop a fuel injector O-ring into one of the cylinders after replacing the heads. Thankfully I was able to vacuum it out without having to take stuff back apart.

OK... make sure there's no broken valve head in the cylinder.

Oh boy....that spark plug doesn't look good!

You can definitely run a bore scope in the spark plug hole to see what you can, but at the end of the day I think the heads are going to have to come off to assess the damage and see if the engine is repairable.
