I turned my phone on this morning and scrolled down through the stories on the net and there was the Hagerty article about Grizzlies and your knowledge about them. Need to convince the owners of the double cab to fix it or sell it to someone who will.

It's why I posted the MSN link in post #1440

There were lots of great ideas about equipment that came from BC.

I thought it a little odd that wasn't mentioned too considering Pacific was started by ex Hayes employee's. Sad to see all of these companies closed. They built some of the toughest trucks ever.

Hey Will...any updates on your truck ????

Unfortunately no.
I've changed the injectors out, which was needed anyway, they were pretty dirty. That really helped with power, it's a different truck power wise but the ticking is still there.
I've listened all around the engine with a stethoscope, the ticking sounds loudest at the back of the engine, down low on the driver's side near the starter and around the front of the bell housing. I read if the starter isn't pulling the bendix back all the way that can cause ticking. I put a new starter on it too but no luck.
The odd thing about the ticking, when you first start it and the engine is cold, there's no tick. After it runs for about 30 seconds it comes back. If you lug it a little letting the clutch out the ticking goes away too. The truck runs great and has plenty of power but not being able to find the cause of the tick is worrying me.
I have it booked in to a different shop Wednesday morning for an alignment and to see if they can find it. If they can't I'm going to change the oil and see if it's making metal inside. I hope it doesn't come to it but it's looking like a compete rebuild might be in the near future. I'm too far in to it to not want to drive it for fear of what's causing the noise.
If anyone on here has any ideas, I'd sure be happy to hear them!

Could it be something like the throwout bearing? That the ticking does go away in certain situations makes me think it isn't a serious problem

Wow....I get it.That would bother me and i wouldn't be happy till i knew the cause.,Time to send a oil sample to Finning...

Did you guys look at the rods & mains while the engine was out of the truck or while you were rebuilding the truck?

Only what could be seen when the oil pan and head were off. The engine was running fine at that point so we decided not to open it up any more than necessary. Everything that could be checked was tight, no play or slop at that time. When the clutch was changed the second time and the new flywheel was installed (after the ticking started) the output shaft at the back of the engine was still tight.

I know this sounds crazy but you have a cracked exhaust manifold?

I've run my hands all around it and tried to look with a flashlight when it's cold, I can't see anything.
The ticking sounds sharper than an exhaust leak. I tried to attach a video but it doesn't want to upload.

This is a 12V isn't it? Anywho-lift pumps on small Cummins have been known to be noisy.
Guess how many FE block Fords had lifters changed-only to be a worn out loose fuel pump
arm.

Not being at your place limits my trouble shooting ability. Here is something to ponder. The valves and pistons are operating about 17 times a second @ 2000 RPM and about 7 times a second @ 800 RPM. That is almost too fast to be able to distinguish a click. I'd look for something that is gear or belt driven that is not moving so fast if you are hear a distinct clicking. Just a thought that might not be worth a darn..

Fair enough on both points but the noise does seem to be coming from the back of the engine, aside from the lift pump there's nothing back there that I can think of that's gear or belt driven.
It is a 12 valve, i have heard of the lift pump getting noisy. I put a new one on shortly after I got the truck (4 years and very few KM's ago) and listening to it with the stethoscope, the noise doesn't seem to be coming from the pump.
It is certainly louder down by the starter.
Thank you all for the ideas, keep them coming!

Unless there is a bell/rear structure bolt that's backed out hitting flywheel, Had two 6NZ Cats that
happen to, found them snapped off laying in bell.
