And now to yesterday, destruction day.
I ended up driving from Hyder AK to east of Prince George the day before and the knock went from occasional to now being constant. But not too loud.
Yesterday I went from east of PG to Calgary AB where the truck blew up.
I did some small diagnostics to see if it was a stuck injector or the water pump. So I cracked the fuel lines. No change to the noise. Then I took the fan belt off the water pump to see. No change to the noise. Uh oh.
I still had the long drive through the icefield parkway to get to Calgary. Lots of hills and lots of elevation gain and worst of all, no cell service.
So as I drove back into Alberta, the knocking was getting really pronounced. In hindsight, I probably should have pulled over and had the truck towed into town, but I was too confident and hopeful that it wasnāt something catastrophic.
As I made it to Lake Louise I got cell service again but still had a 2 hour drive left. Yikes. The rattling got worse.
So I drove at a meagre 90km/h the whole way back and eventually made it into town. The knocking was really bad by now. But I made it. I made it to a city where I had contacts so I was hopeful.
This entire day I would shut the engine off on prolonged downhill sections and coast down in neutral so that I didnāt have to use the engine. I think I saved it for a few extra kilometers that allowed me to get home thankfully.
Once I was in Calgary, I made a drive to my old house that I still own and was planning to pop in for a quick visit then visit a mechanic buddy to get the problem looked at.
Just as I rolled up to a stop light only a block or two from the house. I shut down the engine and when I went to restart it and pull away, I was in first gear, pulling away and then BANG!! I heard a loud noise and then the sound of a whole lot of metallic noises fill the drain pan. It sounded like someone took a punch of pennies and tossed the into the engine block. And then, nothing!
The engine continued to run and there no longer was any knocking! What the heck???
So I immediately pulled over and shut the engine down. I walked back to the spot on the road it blew up and looked for oil or any indication that I punched a hole in the crank case.
Luckily no Swiss cheese engine block.
So I drove the truck another probably 1km by turning the engine on, getting the truck rolling, then turning the engine off and coasting. Once again the truck ran and the engine pulled like normal.
I think I blew the bottom end and a bearing.
If the engine would run too long after the detonation, you would hear a loud squeal that got worse. I never let it get that bad as I would keep shutting the truck off.
After a very short drive back. I parked the truck at my house and thatās now where it sits until I can get a shop to look at what blew up and source more bottom end parts for this 3B engine.
yikes.
I am lucky that the truck got me all the way home and didnāt blow up on the long stretches of road without cell service or shops for miles and miles around. I was very lucky all things ls considered.
Should I have driven the truck 1000km+ with a knocking noise? Probably notā¦
Time to see what the cost will be and if I can even get this fixed! If there are people with spare 3B engines sitting around or parts hit me up. Iām in the market! Hahaha
The story continuesā¦
