Blew oil line engine now toast! Cat 3116 getting replaced

Dirtdiggler · Sep 19, 2017

First, hello all. Long time lurker.

We bought an M1079 and have been doing a lot of work and driving it a LOT over the past summer and this weekend that came to a screaming end when an oil line ruptured and subsequently so did our engine as we descended Washington pass.

Happy to elaborate, but right now my main interest is finding a new engine for this baby as it is our full time house right now. Anyone have one they want to crate up and send to Mt Vernon?

FYI we are on Instagram @dieselpowerwolfpack if that's your thing...

Sorry to hear and also sorry no spare 3116. Just checking but Mt Vernon Wa?

I swapped engines in June, it's a lot of work. It took us like 5 full days (sun up to sun down, on the longest days of the year), plus 5-6 more days of 4:30-9PM. We hadn't done it before, but I have changed engines in things before. It was also tough to find a rental engine crane that could lift high enough to get it out... the one we had cleared by about 1", and only while twisting the engine and pushing it around the shock tower.

Having a forklift or boom makes it easier. Comes right out with the cab folded. The trans bolts can be a pain. Still a big job.

This is the line the broke. It's a small metal high pressure ling. Evidently the sensor for pressure and temp are in the sump and so there was no loss of pressure or heat issues until we were basically out of oil. Pretty sure I dropped a valve.

How much and what's the story with the engine? Thanks!!

I've been following your adventures on Instagram. Could it just be a top end rebuild? I'm far from an expert but it might be worth checking out.

Same line went on my 3116 that I had but I shut the engine down right away.

Dang man that REALLY REALLY sucks. I plan to look at mine and change it prophetically I think. Wow, wish I had better words of encouragement than that. Good luck on your replacement. And if Will (Supermn) says its right. Its right. If you are in need get the engine and get it done.

If it dropped a valve it will most likely be more than a top end rebuild. Probably took out a piston and maybe bent a rod as well. If there is coolant in the oil then it broke a cylinder wall when the piston failed or the head was broken through where the valve was pushed up against it. That is the road I went down with two motors that dropped valves.

Dirtdiggler · Sep 20, 2017

I really doubt it. After I had the new line made we drove out about 6 miles with about 70% power and then THUD! And all the oil and coolant came rushing out. There were a couple sheared bolts as well. Not sure if the cam went flying forward or what but it's done.

Freight cost CT to WA going to a biz address with forklift or loading dock to unload is around 1000 bucks. 5-6 days transit.

That seems right.

Yeah. Cat dealer there willing to do the swap and was pretty close to where the truck died.

Good for you! How did you know it broke?

Suprman · Sep 20, 2017

I find most cat dealers are good with the lmtvs. Not the cheapest around but you get what you pay for.

Adventure Driven · Sep 20, 2017

Does anyone have a part number for this steel oil line that blew, I want to buy one today!!!! Not playing with this, don't want this happening to me.

Oil pressure dropped and I pulled over on the side of the hwy and saw all the oil on the ground. I have pics that I uploaded onto here in my thread. Along with that line, it also cracked the timing surround which you can see in that photo. Seems the culprit was the air compressor vibration.
