7.3 turbo idi, bad miss, injector? no compression?

Any bubbles or oil in the coolant?

 

[Still Strokin]

No sir. Sure doesn't. I know from past experience , oil in the water has been a bad oil cooler... And water in the oil itself has been cavitation

 

[NTOLERANCE]

Did you take the readings with all the glow plugs out?

 

[Still Strokin]

Yes I did. I let it "hit" on its only compression stroke 6-8 times on the cylinder I was testing then recorded the reading

Old thread ressurection.

Ever tear it down or sell it and figure it out?

 

[Still Strokin]

I pulled it and parted the truck. Put the engine in the garage and just deemed it a builder. Prolly a burnt exhaust valve. Saved it since it's a turbo block

Huffing and miss

Like the previous said this is an old post but I seen this post last night and had to comment. I have had to 7.3 IDI engines. Both of them had badly worn exhaust valves. These guides get so bad the valve wobble side to side and makes the misfire. This is what happened to me twice. It is due to an update with Ford for valve stem seals on the exhaust side. This cut down on emissions. But cost us engine problems later in the years. I hope this helps someone that reads this post. Thanks southern militia
