VERY annoying R1 engine problem - worth seeing what happens on restart?
I was at Pembrey for a trackday on Saturday. Had the most annoying failure thanks to a M6 bolt winding its way out...
Using a random image from Google, the very rusty pipe in the centre is secured in place by the equally rusty cap head bolt to the bottom-right of it
(mine are in much better condition by the way.) https://images.app.goo.gl/Ypk9nZcvu8T5UqWa9
Anyway, for those who don‘t know this pipe transports coolant from the integrated oil/water pump which is housed in the oil sump. A water-tight seal
is assured thanks to a couple of o-rings. What has happened here is that the bolt has backed-itself out, the pipe has followed and the coolant has
therefore been pumped directly into the sump/motor.
In hindsight, the first signal was clutch-slip but it ran for something like 10 minutes like this before it all escaped via the catch tank and I
really knew I had a problem when my feet slipped off the pedals. It still got me back to the pits.
I’ve removed the sump and water-pipe drain plugs - not much in the cooling system and lots of water in the sump.
I’m resigned to the fact that the engine MUST be toast but since it was running, I can’t help wondering if I should clean it up and refill with cheapo
oil and see what happens on attempted re-start. It feels like it might get some YouTube hits (if I were so-inclined.).
Shall I stop dicking-around, pull the motor out, save the cases for a later engine build and start saving my pennies for another (3rd now) motor?
I would fill it up with some fresh oil, turn engine over to circulate oil and check for any tightness, possibly a compression test too and start it
up, it will become apparent if there is any serious trouble. What have you got to lose apart from the cost of a gallon of oil?
Not a bike engine but a skyline 6cylinder the oil cooler pipe come of and blow oil every where the engine seized we repaired the pipe and replaced
We kept towing the car and it started the car was used for two more years before getting the engine rebuilt
So there is always a chance
