I will try to find one at Habor Freight or Home Depot / Lowes. If they are not in stock and one needs to be ordered online I may take you up on that - I don't want to wait for shipping..... I'll PM you my # if I can't locate one. Thanks for offering!

 

Just let me know so I can toss it in the truck. I work in Annapolis, so it's no trouble to swing by on the way home. My hours are flexible.

 

Well I've got good news and bad news. The good news is I found the screw...it was not in the cylinder. But this is what I found in Cylinder #8 - (coolant sitting on top of the piston)



This scope camera works sweet!

At least I found the coolant leak! - Now I need to decide what to do. Do I return the injector for a refund and call it a day? Then start looking for a new motor / new truck? Do I replace the head gaskets?

Plus I am not sure what is causing the fouled intake runner and plug? The runner smells like fuel, but it looks like oil. It could be a valve guide, but the back of the valve looked ok. (i'll try to get a photo with my new toy.) Plus if it was the valve guide why would the oil work its way all the way up the intake runner?

I can try a compression test and see if the valve is hanging open. but wouldn't this cause the truck to run like sh#T? I only experience a rough idel at start-up.???

 

Not really to sure what we r looking at. Slipped sleeve? Is so, you can always have it bored and resleaved. Id have all redone. That way you block should last another 200k.

 

Could just be a blown head gasket. I'd pop the head off before I got too crazy. If it's the gasket leaking you should be able to tell. You can pressure test the block while you have the heads off. Do the job yourself and you are only in it a couple hundred bucks. Doesn't cost anything but time to take it apart first though ;-)

 

x2 on investigating a little more before condeming the engine the #8 is right next to the water jacket. you said the gasket were done at 170k and now you have 230k so thats about 60k on this set of gaskets, it seems 70-100k is the norm on a lower milage engines. Were the heads milled? is that picture with the system under preasure or not? maybe under preasure would give you a better idea? just throwing ideas out there.

 

nope to both comments. The heads were not milled and the system was not under presure. The truck sat for about a week and then I started pulling it apart.

I had to pull the radiator to put in the power steering line, so no coolant in the system other then what is left in the block.

I am at a cross roads hear, If I pull the head(s) and verify the sleeve hasn't dropped - then that should fix the coolant leak. Then I am still at a loss for the fouled plug and intake runner.

Any ideas?

 

Could be the coolant was fouling the plug on startup and the unburned gas was igniting when the coolant cleared out and the plug started firing. You would of been getting flames in the intake runner when the fuel ignited.

 

pull the head and verify the two possibilties. If its a slipped liner, well you can alwas resleeve it. it'l cost you but you motor will last another 200k. If its a head gasket, well you found the cause of both your coolant leak and your misfire

 

I would tend to think the same way, if that much cooling is in there on start up it has to be soaking the plug causing it to foul on initial start up. What do you have to loose by pulling the head? if you decide you need a "new engine or a new truck" what could it hurt to pull the head and look? The gasket may have failed simply because the head after 170k probably needed to be milled.
