R1 water in the oil
ChrisS - 20/2/08 at 04:10 PM
Whilst doing some work on the clutch as the diaphram spring popped in yesterday, ive noticed that it seems as though the few times ive run the engine
during the build, has caused some water to go into the oil. (When i say water, i mean contamination, not like buckets of it)
The engine had been stood for quite a long time and i put new oil in it before starting it etc etc.
I think i read somewhere its got something to do with the water pump and wondered if anyone else has experienced this and could advise how to rectify
it, and whether the engine will need to come out to do it.
Thanks

Just spoken to the local Yamaha Shop Mechanic who says its unlikely to be the water pump as they have fail safe water drains. He said they do suffer
with condensation in the clutch cover and oil level window.
He also said it could be a head gasket problem but the motor would run very steamy, and gurgle loads of coolant back into the header tank?
ANy ideas much appreciated.

If you’ve just run it at idle and not actually driven it yet I wouldn’t worry to much its probably just condensation. An oil and filter change before
if goes on the road would be my advice!

what sort of amount we are talking aoubt. teaspoons or teacups?
can yoiu tell if anti-freeze is there in the oil as well?
Is the water getting lower in the radiator? That is a sure sign you have hg probs.
Remember water is denser than oil so will sink to the bottom of your sump, as well as get mixed into an emulsion.

when i took the sump off i actually did damage an O ring, but i replaced both of them with new ones, but im not sure if they were water pump drain
pipes? Its difficult to tell how much water, but i think its teaspoon full rather than teacup full.
Having just wheeled the car out for a quick spin round the yard, ive now developed a misfire on no.2 (Well actually not firing at all). Havent taken
the plug out yet, as my socket has gone missing, BUT could this also be a sign of a Head Gasket problem?
Im so gutted, as the car is now driveable and wanted to have a quick drive. ARGGHHH!

Hi it sound like condensation at first but the missfire may now prove different
run the engine till warm and remove the plug from missfiring cylinder if gasket has gone there will be steam coming from cyl and after a while
if you spin engine over with plug out there will be a small amount of water pushed out
indicates head gasket or crack in head or jacket

What i dont understand is that the engine has been running fine for months in the idle/reving up situation. It hasnt been driven anywhere or
overheated, so why would the head gasket go, or whead crack! Im puzzled. The only thing i didnt do was put coolant in it in case i needed to drain it
before putting it on the road.
PS is head gasket replacment a difficult job, or just the same as doing a car?
I think theres a case of sods law here.

Assuming you haven’t run it for long with no coolant but have been starting it up at idle and just giving it a few revs every now and again, it could
be the water is just condensation and the misfire is the plugs fouled up!
From experience bike engines have a habit of killing plugs if your just starting them and not actually using them!
A new set of plugs would be a good start assuming it fixes the misfire warm up to working temp and see what happens.

Strangely enough, ive just put a new set of plugs in at its sweet as a nut. So yes your spot on thanks. as for the condensation i think your right
along with other opinions, and that is that R1's suffer with condensation, and the engine needs to be run properly to avoid this in future.
Thanks for everybodys help. Just for reference though, the expert opinion was that unless the engine had been seriously cooked it was unlikely the
head gasket would have gone as their a triple layer steel and dont break up like old car ones used too even when stood for a long period of time.
Once again thanks all.
