Oil in water xciting 500

[xsel777]

Hey good people.
I rode it for 1km and it overheated.
I waited 5 min, and carried on.
Starting was difficult.

I got it home.
3km ride .
Stripped off the plastic.
Took off the radiator cap.
no water to be seen.
I put 500ml antifreeze in(half a bottle).
Started.
Antifreeze blew out the inlet pipe like a volcano eruption!
I refilled, emptied the antifreeze bottle.
restarted. with difficulty.
Noted white smoke from exhaust.
Turned off engine.
refilled radiator as the level had dropped again.
cap on, attempted restart, and the overflow tank overflow pipe spewed antifreeze.

At this point, the conclusion is conclusive ;
crap job.

I am disappointed, but cant go there to express it fully.
I will talk to God about it instead.

So, back to the workshop  it goes.

Thanks CROSSBOLT.


BTW, the brakes are fine......

.....oy!

I am only a bystander but I would like to see this issue resolved asap.

[xsel777]

mousejunks, me too.
I can secure a complete 500 for a fairly reasonable price, a carb version, 2007-2009 abouts.
The crank is gone and cost of replacement is more than the scoot is worth.
If the crank is so much, I can only imagine what the barrel and head will cost.
So, a potential idea is to swop out what I need to get mine going.
I don't really want to  go this route, but the advantage is I will have plenty of spares(but nothing EFI related).
I actually am at the end, because the exchange rate is crazy(14.5 : 1),and now that Yamaha is the agent, the prices went crazy too....
I cannot buy on credit, through the bank, as my business has very erratic cash flow, so the banks will balk.
I think this; I have never tried, as I see my bank balance, and I would not risk me.
All stock that is available is of the Chinese variety, and I would rather walk than get one of those.
Anything that is higher than 150,and not Chinese, has a premium here.
I have been looking for divine intervention/assistance, because it is all getting beyond me.
Not giving up though, just outlining the situation, as I see it.

Well, I went around to the workshop, and the consensus is that it is the head bolts are stretched.

Yeah, if you had TTY head bolts they are one-time-use only.
I guess that big 500 pot could stretch a headbolt. Thought only iron car engines could do that?
In any event.....I could be your agent if you decide to do a NETFLIX series.
Seriously,  best of luck with this.

BTDT: I had to keep a Beetle with 195,000 miles running during some lean times in the 70's. When child #4 came along, told the wife maybe we could "stack them?"
She said, "no".

[xsel777]

I think they stretched because the head has been off about 6-8 times during the time I have owned this scoot.

We are looking for extras, particularly favouring those who can laugh like hyenas!

According to the mechanic he has fitted new head bolts.
Engine is back together.
Still to do:
clean out coolant system (oily), and test drive, but not just around the block, a bit further.

Tomorrow is D-day, because finally it is sorted. Speaking positively.

At least today it did not overheat, when I fetched it ; in fact I never got out of the parking lot, as it would not start.
If it struggles to start, could be compression leak again, or some other issue.
This time no coolant spewing out of the expansion tank overflow pipe.

So possibly compression leak small, like before I brought it in for repairs, or some other issue.

They did not use the original gasket, just the copper one, so they must be confident it is working.

It did drive fine during the test ride.

Ph well, Netflix weekend then.

I can't expend any further emotional energy on this, it is a soapy, without the torrid love triangle.......[emoji3].

Possibility I will be riding tomorrow, although I am concerned about one thing.

There was no spark, after a test ride, and the shop rerouted wires/made new wires , tested the ignition, replaced coils, and drained 8 batteries and the charger,
until....
I rocked up with a new Motobatt MBYZ16HD and an iridium Cr8eix plug.

all good it seems.

Just to put the plastic back on, test it and clean it, for pickup tomorrow.

Here is my concern :
The bike was cold, it had not started since Friday.
I undid the radiator cap, and liquid started squirting out under pressure.
My experience has been, that once it is cold, the pressure reduces, so it is easy and safe to remove the cap.

I asked the new mechanic if he was confident that the head  gasket was now properly secure with the new head bolts, and he assured me it was.

Your view on my concern, or am I just being too jittery after all the issues I have faced here, feeling somewhat traumatised.

Your concern is valid.

[xsel777]

Well, I got it back.
Things noticed : appears 6 month old waterpump is leaking, green liquid.
Upon closer examination it is a water pipe above the pump,these pipes are not in good shape, as they have had oil flowing in them for awhile.
When bike has cooled down I will sort that out.
Engine light is on, so I am assuming is due to them working on the bike.
To be noted is that two previous O2 sensor heaters have blown, engine light comes on then.
I have a Chinese OBD computer checker.
I will check that out too.

Update to follow.

Things just got steadily worse.
1L coolant required.
White smoke from exhaust.
Difficulty starting.
Back she goes.

"Toyota 4th of July Sale-A-Thon is going on right now! See your local Toyota dealer for some amazing deals!"

Oh wait - NETFLIX doesn't have commercials!

put a face palm right here
