105 Cruiser - ticking sound from Motor (need for worry??)

same donk and same noise as mine I would guess.

The toyo dealer says I've gotta expect that - but they would wouldn't they!

Tappets are described here: http://en.wikipedia.org/wiki/Tappet

I've not asked or looked at how they are adjustable, nor do I know if this will properly fix the problem.

Toyo dealer blamed thinner third party oil (gottaluvem) and suggested that the thicker stuff they OEM may "fix it".

For now, it doesn't bother me that much so I'm not doin' anything about it.

There are sure to be some here who know the internals of the 1HZ and can comment in more detail.

Ciao for now
Andrew.

Thanks for the thoughts Andrew. I would probably let it go as well (iif not a big problem) except that I'm heading off around OZ in a couple of months - and towing a trailer so want to make sure it's in TOP nick.

oh no ......... that would be just my luck!

No doubt that is a BIG job to fix ---- before the BANG I mean?

Actually it is a very easy job to do before the bang, about $500 in bits and not a lot of labour from what I hear.
Very hard to pick without actually having a look from what I understand, that is why the suggestion to get an experienced bod to have a listen/look asap. I'd reckon most of the bigger 4wd service centres would be able to diagnose.
If it is a loose tappet you can usually tell by the fact that it is high up in the engine bay, try using a big screwdriver as a stethoscope (sp?). Remember though that the rocker cover is plastic on the 1HZ. I found that out very early in my ownership, left a hot soldering iron sitting on the 'alloy' rocker cover!

Hi Traveller,

Smitty's problem will not be the big ends.

Factory Turbos (since 1986) have always been a vastly different motor to the normally aspirated diesels. The factory motors are direct injection, and more recently EFI and 24 valve, and internally have many other differences.

The 1Hzzzz normally aspirated motor has not suffered big end problems, even when turboed. The 1990-94 1HD-T motor was the only model withg the big end issue. These motors usually fail without warning.

What I meant was that the motor's are very similar in basic design and if you fit a turbo to a 1hz it is then subject to the same stress's that a factory donk has without the mods done to enable it to cope with the stress. I've actually seen several 1hz's fitted with turbo's with the big end problem over the years, alll comes back to how it is treated and maintained.

like Des Lexic's

Hi Nudie,Theres a whole world of LandCruiser numbers out there just waiting to be pinned on the back of your toilet door :-)) We can test you on it next week:

120series = Current Prado
100 series = Independant front end "100series" (TD and V8)
105 series = Rigid front end "100series" (1Hz and 4.5 litre)
90 series = 3-door Prado
95 series = 5 door Prado
78 series = Troopie after 1999 (and curiously also the original Prado that didn't make it to Aus)
79 series = Cab chassis after 1999
75 series = Troopie or cab chassis from 1985 - 1999
73 series = Mid Wheel Base (usually FRP top up to 1990)
70 series = Bundera
62 series = Petrol 60series from '87-'90.
61 series = Factory TD 60series '86-'90
60 series = All other 60series
55 series = Those rusty ones with drum brakes up to 1980
47 series = earlier troopies and trays to '84
45 series = before the 47 series
42 series = The last of the 40series witrh front discs and power steering on the 2F, and 3B.

We could go back to the 25 series, but this is just some of "what you are missing" :-))))

Cheers
Phil - bored tonight

Hey Phil, you forgot the 80series :-))))) Don´t let that happen again. :-)

Ulises

Great info Peter.

Was a new gasket required for the rocker cover?

Was it a Toyota tool, or is it something every good mechanic will have?

Ciao for now
Andrew.

Morning Eric!

That's exactly what I was thinking - Problem Fixed :)

I received a reply from Peter - he suggested I get a copy of your Cape York DVD.... like the diff-lock it sounds like a good idea!
