In this episode of Sailing A B Sea we call in our top mechanic to find out why our engine turbo fell apart.

The first sign that our engine turbo fell apart was the white oily smoke coming out of the exhaust. The second sign was that we were burning engine oil at a rate of 2 litres every 4 hours.

We've just spent five days on anchor at Kekova

Roads checked out a couple of anchorages but we've

got a bit of an issue with the engine now would

you believe! We're blowing out white oily smoke

and the engine is chewing through a lot of oil

This is the next addition that we're planning

for A B Sea. We're not quite sure yet whether

we're going to put it on the foredeck

or on the solar panel arc. Maybe you can

drop a comment below and let us know

where you think it will be best positioned

He's obviously paying a lot more for his anchorage

spot than we are! This anchorage at Kekova Roads

in Turkey is a mixed bag for me it is a wonderful

spot to drop your hook, it is a mud bottom so the

holding is absolutely fabulous, the protection

from any wind or swell is brilliant as well,

however it does get very noisy, there is a

constant flow of day tripper boats going in and

out of the marked channel just behind these small

islands here. The beauty of the place is amazing

but if you're looking for absolute perfect silence

this is definitely not the place to anchor. So for

me it's 50:50 really it's a great anchorage that

you can drop the hook and swing freely without

any concerns about hitting the rocks or banging

into another boat, there's plenty of room in here

but the noise factor kind of spoils it a little

bit. Bonuses are that you can go into the small

town here for dining out or provisioning and

even buy basic boat bits like engine oil,

Turkish flags and stuff like that. You've also

got this amazing old castle to visit. Tucked

right inside the bay is a boatyard and you

can tie your dinghy off to a pontoon there.

It's nothing spectacular it's nothing flash, it is

very basic and then you can walk up to the castle.

We've just spent five days on anchor at Kekova

Roads, checked out a couple of anchorages,

but we've got a bit of an issue with the engine

now would you believe! We're blowing out oily

smoke - it's white oily smoke and the engine is

chewing through a lot of oil, so we're now heading

back to Kaş and I've taken some video footage for

Aydin the the engine tech guy and I'll show him

that at his workshop and see if he can diagnose

what the issue is. We'll probably need to get a

compression test I would guess so yeah next big

thing on the list: finding out why we're burning

through so much oil and just try and get the

engine running normally. Fun with boats hey!

It's just after eight o'clock on

Monday morning and today is the day

that the best mechanic in town, Aydin, is

coming to visit the boa. He should be here about

10 o'clock to start actually looking directly at

the issue that's causing the oil bur. We've had a

lot of chats over the weekend with a lot of people

and it seems to be spread across the board whether

it's going to be the injectors, the turbo, or

the piston rings. My best guess is that it is the

turbo because I've been doing a lot of reading

about them and they're very prissy, they they

have to be babied a lot, they spin at really fast

revolutions, they work at very high temperatures,

so if you don't start your engine up properly

and shut your engine down properly then they

get a bit pissy. In a way I'm kind of hoping

it is the turbo because we used the boat for

nearly two years without knowing we had a seized

turbo and we got excellent speed out of her so

if it is the turbo I'm just going to ask Aydin

to build something, remove the turbo and build

some mechanical piece to bypass where the turbo

should be because I'd rather not have one and

have all the messing around with having to work

with a turbo. So yeah I'm just about to get the

boat ready, I've got to take a few doors and

cover doors off and prepare the two aft hatches

for an oily mechanic, so yeah count down

to 10 o'clock. Let's see how it turns out

eh? I'm getting that deja vu feeling with the

cabin door and the inspection panel doors off

and the good old engine exposed. The main reason

we've done this is so that Aydin has very easy

access to the engine and the parts he wants to

work on, but also with the door still on here

and open you have to have the cabin door closed

as well and the heat that builds up inside these

cabins it is still reaching temperatures of 35 and

36 degrees here at the moment so it's just not a

good working environment so we're going to try and

keep him as cool and hydrated as possible and that

way he can get on with the job and hopefully find

the problem and the solution. Here is Aydin now!

Oh look he's ready to go he's brought a trolley

full of tools. Günaydın. Günaydın. Aydin's

been here for about 20 minutes now

and he's already said that he's 90%

confident that the problem lies with the

turbo so I've just discussed with him that

if it is certainly the turbo then can we

get a turbo off, throw it in the sea and

have an engine without a turbo because they

are a real pain in the bum. But not throw

it in the sea... No not literally throw

it in the sea! Especially not in Turkey!

Okay so this is a part that we've had off in the

past and when we first took it off it was oily

like that but Aydin seems to think that this

is definitely not normal and a lot of oil. Ooh

there's actually... I can actually see oil moving

in there. Yeah yeah yep yep. So there's tons of

oil just throwing itself into the turbo system.

So once again we're taking off the turbo unit

andI'm going to guess tha Aydin's going to take it

all back to the workshop and manufacture something

MacGyver style to remove the turbo unit from the

whole system and then bring it back and reattach

it. We're now looking at the engine minus

the air intake turbo and exhaust system agai,

so while Aydin takes it back to his workshop we'll

get this all cleaned up. I've just had Tayfun from

further up on the pontoon come and tell me that he

had a phone call from Aydin. Aydin wants to see me

in his workshop in town so time to mask up and

go and see what's happening at Aydin's workshop.

Hopefully it's not bad news. Okay so here we are

at Aydin's shop in Kaş town. He's disassembled the

turbo system and basically it's just collapsed.

So this is the broken piece here? This here.

Aha so that snapped off there yep? This broken.

Okay and all of these blades are broken too (do

it that way), see how this one's going to point

you out bit this bit's broken off and you can see

here the blades they've been wearing against the

inside so basically it's come unbalanced and just

packed in basically. Yep so we're gonna put all

this lot back together after it's been cleaned

and we'll see Aydin back at the boat. I've just

heard a trolley coming down the pontoon, is it

Aydin with his trolley full of tools and then

and a re-engineered part to fit? It certainly is.

Okay so this is looking inside the turbo

where there would normally be a fan on a

spindle. So basically what Aydin's done he's

created this replacement disc. Aluminium parts

to close it off completely. So fresh air comes

in here through the air filter, bounces around in

there and just goes straight to the engin. Engine

exhaust attaches here and goes down here and then

just exits through here into our exhaust elbow

and also Aydin has closed off this section here

which was basically the oil feed so the the oil

for lubricating the turbo would come in here,

lubricate the turbo and then go out through there.

So that's basically all being shut off as well.

So the turbo has been eliminated from the

system. This is a part of the fresh water

cooling system and so that still runs as it

normally would and of course the salt water

attaches here with the exhaust mixing elbow,

that's why it's called a mixing elbow because

the exhaust fumes come out and the salt water

comes out and they mix and they go out the boat.

Right now we've got the fun task

of putting it all back together!

Just to finish off this segment about Aydin coming

on board and troubleshooting our engine issue,

I've just got to say that I am feeling so stoked

about the outcome and the whole process really

it was absolutely fantastic, I mean we've

said it before that Aydin is an absolute

genius when it comes to mechanics and you know

again once again ... he'd never done this before

here's something ... we were talking after the

job and what he said to me he said he phoned up

Yanmar in Yanmar J blah blah blah blah engine

and Yanmar Turkey said you can't do that

and Aydin asked why, why not, why can't I?

and Yanmar said well you just can't it's a

turbo engine you can't take the turbo off. So he

said okay how much is a service kit for a turbo?

And he said oh we don't do service kits for

those turbos so Aydin asked how much is a

replacement turbo? And they quoted him 3,400

Euros for this little turbo piece that bolts

on and he said okay thank you very much. So then

Aydin phoned his turbo specialist guy in Istanbul

and asked the same questions and he said yeah

sure you can do that but you might get black

smoke coming out of the exhaust when the injector

nozzles inject too much fuel into the cylinder and

it all can't be burnt off and that ejects out

of the exhaust and comes out as black smoke.

So yes it can be done but expect this and then

you may have to change down the injector nozzles

to a smaller siz. Okay we're just about to start

the engine, I'm pretty confident that we've got

everything, we've reconnected all the hoses

and the hose clamps, we've got the oil level

just where we want it to be, we've refilled the

fresh water system, we've blocked off all of the

oil in and out places that are not in use now

that we're not lubricating the turbo part of the

engine, everything is back in place, all the pipes

are where they should be, all the hoses are solid,

so we're going to crank her over and see what

happens. I mean I've got trust in Aydin and what

Aydin and I've just done but you know, it's still

a bit nerve-wracking. Okay. Okay start. Okay!

That's a relief to say the least, we took her up

to 3,000 revs slowly slowly, Aydin was expecting

to see black smoke up at the higher revs because

the injectors were pumping in more fuel than

could actually be burned so it looks like even

with the turbo injectors in place, the nozzles,

we're not putting in too much fuel into

the system that it can't burn at all.

We are seeing just a little bit of kind of white

smoke which is pretty normal for a diesel engine

so Aydin says leave it for 20 minutes now

just let it run at 2,000 revs for 20 minutes,

help clear all of the excess residue from the

issue out of the system and then we'll take

it up to 3,000 again and see what it looks

like. So all in all quite pleased really!

He's a legend isn't he? Aydin is the magic

mechanic. As it turned out it was all great

but I probably mentioned this previously but the

thing is yeah I'm absolutely stoked right now.

The fact that we've got A B Sea, her engine, her

heart beating as best she can, we've got no more

concerns about having the turbo, having to service

the turbo, things going wrong with the turbo,

so I'm absolutely stoked, just feeling really

really good, Just thought I'd share that with you.

We are so glad that our engine

issues are all sorted out now.
