What a sick feeling, truck stumbling and oil not in the engine
Driving home tonight pulling the sleds, nothing crazy for speed, all of a sudden, I just happen to catch the indicator light on the trailer brake controller fade out. First thought, thats odd, plug for trailer must have come undone. Then the truck stumbled a bit, and then started loosing revs (Still had foot on throttle). So I pulled to the side of the road. When I got stopped, the truck was idling LOUD, and sounded very unhealthy.
Then I looked underneath, oil pouring down , leaking all over the transmission, skid plates, everything was dripping. My first thought was transmission fluid, because thats where it was the wettest. Upon closer investigation, it was coming from the rear of the engine. I put my finger in it, and it was engine oil. Not just engine oil, the 14 litres of Amsoil 15w40 synthetic I just put in it (most money I had ever spent on engine oil).
Crawled on top of the engine, and sure enough, the valley was covered in oil, and running out the hole in the back. Then my brain starts trying to come up with what could cause an oil leak in the V. HPOP, HPoil line, IPR. I have not had this part of the engine apart, so I was floundering in uncharted territory. Of course by now its dark out, with no flashlight, trying to use my cellphone screen as a light to see any leaks.
Its now tow truck time. Call one, he tows me into town. Get to his shop, and the plan was to fill the truck back up with oil, fire it up, and see where its leaking. This would be a great idea, if we had 14 litres of 15w40 oil. We scrounged 5 litres of Co-op 10w30, 3 litres of Case IH SAE 30 oil (with the $1.00 stickers still on it from the yard sale he got them at), and 2 litres of Esso 10w40. Poured it all in, and it fired up.
Finally we noticed the leak under the ICP sender. Unthreaded it, and sure enough, the oring was split. It was also hard and brittle, but it was soft and pliable when I installed it. This is the same oring on the sender that I had to make work with a home made adapter, after getting the wrong one from an ebay purchase.
We changed the oring, and teflon taped the crap out of it, threaded it back in, and fired it up, no more leak.
I was amazed at the short time it took to empty the entire oil pan of oil, through that leak.
I made it back home (140km), with my oily strange brew in the engine. Tomorrow will be oil change day.
AND, now for the best part. I had just unloaded 2 90 litre barrels of 15w40 with only 25 hours of use on it, that had been in the back of the truck for 2 weeks.
Lesson learned, just because something is cheaper on ebay, and you can still make it work, doesnt mean its going to be cheaper in the long run.
