View Full Version : Garrggh ! Where did all that oil come from!

Oh dear. Such dramas my dear.

Off to werk, fire up Ratty, curse the shitty weather, off down the drive, all good.

Down the road a few hundred yards, to the nasty steep downhill give way corner.

Prod the rear brake to slow for the corner. Eeeek - shit why's the rear wheel decided go exploring. Not to mention that it's not actually doing the slowing down thing. And the corner now decidedly close. Oh well, wet roads can be slippery, and the rear wheel will come running back sometime with its tail between its legs. Time to call in Mr Front Brake, no nonsense here.

Yeeeeeekk . And double yeeek. With a Yikkkkes for good measure. Now the front wheel has also decided to play slip slidies. Stick out a foot and a quick prayer to the Biker Gods, and , hey, whadda ya know, I'm actually round the corner, still sort of sideways , but more less facing the correct way. Interesting way to go through a corner on seal, but anyway.

Triple eeek. And WTF. Where did all that oil on the road come from . No wonder I skidded like a skiddy thing. What blanketty cunt etc etc .

Oh, so THAT'S where the oil came from. Pissing out the front of my engine!

Oh dear. Oh Deary me. Oh buggery . Oh my sainted head gasket!

Stop. Curse. Blaspheme. Inspect. With profanity. Hm. Hang on. Woz that honking big hole in the front of the cylinder head. Exposing all the camshaffty goodness of the INSIDE of the head. THAT didn't use to be there! (Well, the camshaffty goodness presumably was, but not the hole)

Ah. That's where the decompressor went, on a previous incarnation of these engines. There should be a Welch plug in there , blanking it off.

No plug. Big hole. Oil comes out of big hole. Bugger. Still, better than a blown head gasket.

Stuff some rag in hole. Check oil level, still some left. Proceed VERY slowly back up road admiring the pretty colours the rain is making. Hm. Pretty colours stop there. And woz that lying on the road. Ahaha. A welch plug.

Collect plug. Limp home.

Heap obloquies on the head of Mr Biff. I blame him. He's welch. He should make his plugs better. All his fault. Always like to have someone to blame. It's a Kiwi thing.

No time to sort it now, I'm late for werk. Put Ratty in gargre in disgrace, pull Petal out. Oh bother, the battery's as flat as a rather flat thing. Good job the Titan is kick start and magneto, then. Battery, samttery, who needs them. Love magnetos I do. And kick starts.

Off again, in a cloud of lovely two stroke smoke.

Tootle along, down the muddlway, down Cavendish Drive.

Two lanes, I'm in the left, minding my own business, when a old brown ute hurtles up past me in the right lane, dives in front of me, and slams on his brakes preparatory to a dive into a driveway.

Oh goshes. Still no big drama, he's not too close, cos I slowed when he dived in front of me. And , without a nice layer of oil to complicate things ,a reasonable application of front brake will keep me clear of his rear. Just part of life's rich tapestry.

Hang on a mo, though. Wozz that in the back of the ute, resting on the tail gate and sticking a couple of metres behind the rear of the ute.

Oh yeah. A honking long length of steel tube. Hm, and where's the (unflagged) end of said tube? Oh yeah, there. Pointing at, hmm , yes, indeed, pointing very nicely at my head. Gulp, I don't really feel like having a four inch hole punched in my head this morning.

Suddenly the distance adequate for an emergency stop has been reduced by about two metres . Leaving a rather INadequate distance.

Lucky bikes is manoeverable , isn't it.

Golly, I still have to get home again. Wonder what else will happen!

Um...bugger eh?

I crashed my bike this morning on an oil slick somewhere out the eastern suburbs - as I was picking it up some old guy goes past on some ancient 2 stroke and completely ignores me....

I don't like holes in engines plugged up with...plugs! They are a problem waiting to happen.Good save - lucky you had the time and space to figure out what was happening and take appropriate action...to an observer you would of just done a couple of wiggles and then stopped the bike,meanwhile a whole lifetime of experiance was passing aboard Ratty.Now you know why engines last so long - oil is very slippery stuff!

I did feel some concerns about the oil slick. But it's a quiet road and I've never seen another bike on it. Cages should be able to cope. And with all this rain it will be washed clean by the weekend.

Well after that little lot, who needs an encore, why don't you put cute little Titan in you nap sack and take a nice bus ride home, either that or pretend you have lost your passport and ring for the rescue helicopter:yes:

Iraq, all that oil was stolen from Iraq.

By Sarge. And Gee Dubya.

Oh good. can I blame them, also. That makes three people I can blame. Mr Biff, cos he's welch , Sarge cos he stole the oil , and dubbya - just cos. I feel much better having lots of people to blame.

If there's a God, brown ute driver will loose it on the oil, go head on into a tree, and get said 2" tube through HIS head.

Yeah,I'd stay at work tonight - sleep in the skip.There is possibly a quincunx with saturn in virgo (it was virgin oil I hope) with mars in aquarius (water carrier,but oil is close)....I suggest a merlo or shiraz to help appease the Gods.

Weird, there was an oil/diesel spill on City Road (off the top of Queen Street, first street down from AMES) which is a very steep one where you're stopped at a big angle for the stop sign. Police had it closed off at about 8am this morning but I have no idea whether it's all cleaned up or not so be careful all!

If you rode bikes less than 30 years old this stuff might not happen! Harden up or I'll give you the Triumph man's perspective on Oil.

And where would be the fun in that? 'Twould be like driving modern cars - predictable and boring.

I had to get an Italian car so that driving would be interesting - Italian electrics (WHY ? do I have to have the bonnet open for the interior light to work!) ; no brakes in reverse etc.

If I rode modern bikes I'd have to buy a Laverda to achieve the same result. Or a Ural.

Well, I set to sort it out today - what with the weather being shit and all.

Gotta say that is one pissant shit bit of engineering.

When they removed the decompressor to makethe XT250 engine into the SRX250, they were left with a big hole in the cylinder head.

So what did they do to close said hole? Just stuffed a bung in it. Just a metal plug, with a rubber overlay , and tapped into the hole. Presumably, originally, a light interference fit. Nothing to hold it in at all, just a tight fit.:gob:

Admittedly, there's no pressure there (apart from some crankcase type pressure), but still !:nono: . I thought I must be missing something, and maybe a vital bit got lost, but checking the parts fiche, no, it's just the plug (which is listed as a spare part incidentally - part no 349210-001 $US3.42).

Which is scarey , cos there's really nothing to stop it coming out again. And if it happened at speed, hundreds of kilometre from home? Ouch . And nothing really to show it's happened , apart from the slidey bit. One problem of a roller big end, no oil pressure to measure, so the whole sump full could in theory escape .:bye: motor.

Not good Mr Yamaha, not good at all.

Anyway I've hammered it back in, well smeared with Loctite, permant grade, high temperature. And staked the surrounding metal thoroughly. And cos I was still nervous I commissioned those well known engineers of excellence, Messrs Gash Engineering (incorporating Bodgers and Bashit Ltd) to make up a little plate to screw onto the mounting where the decompressor cable originally went, and bear up against the plug under flexion pressure. That should at least stop it actually coming out, and reduce anything to a mild oil leak at worst. Looks a bit horrid, but it works. Knew I'd find a use for that old door hinge one day.

Needless to say I will be watching it like a hawk for a while

Incidentally, I had great trouble getting the high temperature Loctite. Everybody has the "normal" stuff, some had the (red) permanent grade, but all just looked blankly at me when I said "high temperature". And, between the exhaust ports on an aircooled engine, it's going to get hot.

I finally got it from Blackwoods Paykel. And I cannot refrain from giving them an unashamed plug. Everytime I get something from them they rise to new heights of helpfulness and superlative customer service. They really are the most clued up helpful and friendly folk I have ever encountered. Absolutely first class service, can't speak too highly of them . Norman at the Dalgety road distribution centre is the man to call on if you need help. Splendid chap, one of the old school.

Cleaned off the oil from the front of the engine, topped up the crankcase, only took 300ml , amazing how big a mess 200ml of oil can make when it's spread down the road, started up (what a lot of smoke, from the oil remaining on the headers, even Petal was envious!), all looks good.

Still a bit worried that I haven't a reason for it coming out, but maybe just the effects of 20 years of heating and cooling, expanding and contracting.I'll be watching it, we shall see.

The publisher is sweating on the arrival of a ural. I await with......something.

Always had a soft spot for the Jota (a bog near rangiriri!) nah they were arguably the first real superbike that old lavatory do ya reckon?

Aaah. If only we could have "Instant Karma" on the speed-dial. :yes: Seems more poetic or creative than a handgun. No complicated explanations needed either. :devil2:
