Hi all I've been going thru some old posts on rebuilds but still need some help. Bought a 1991 turbo deisel with 210000k looked in great condition for $13500. Blows white smoke on start up. Took it to diesel mechanic who did a compression test and said low compression in all cilinders and almost nil in cilinder 4. Short story is rings shot. Can get full rebuild kit for $1300. Have a mate who can do the install for around $3000. Has anyone done a rebuild, any problems and is it worth the big bucks. Seems to run OK may even keep going for years but am planning a trip towing camper trailer and worried about major dramas. Any advice would be of great help.

here's all the work done for you for 3550 if its a 1HZ. copy and paste the link fully reco exch. but I would get a second opinion first and maybe have the valve clearances done.

Are you sure about that? We did a 1997 TD last year. Toyota don't make the engines any more. Lucky a dealer in WA still had one. As for $7K, well ours set us back just over $9K plus another $5K for the injector & turbo overhaul.

Hello George,

We have just experienced the same thing although our car is a Petrol motor 4wd. Our motor is currently being rebuit had all the bore sleeves done and pinned. It has been with the mechanic now for 7 weeks waiting for the machining to be done etc. We are assured it will be just like a new motor, and we shouldn't have any problems with it for at least 10yrs. The cost of the rebuild is $4500.00 we figured that at least if we spend that we know what were are getting and it will be reliable as opposed to trading in for someone elses troubles. We too are about to head off up to the Kimberly and NT for 4 months towing a jayco caravan so we needed something that wasn't going to give us any trouble, as it has turned out our car has had one hell of a service.

We also got the mechanic to change all belts and hose pipes and asked him to look at the timming chain and we will keep the old ones for spares.

cheers
Andrea

Sounds Suss low compression and none in one wouldnt be worn rings with that many ks
either he didnt do the compression test /properly
or
the engines suffering more than worn rings possibly been cooked/valve problems. In this case anything short of a compleat rebuild could waste your money

White smoke on startup is pretty common and is more likely a symptom of poorly functioning glow plugs or whatever a DI motor uses as a pre heat (i think it is a type of element).
Get a second opinion and try and hang around for the compression test

I agree. It has had a hard life to be buggered at 210k or something major has happened such as overheating. I would get a second opinion. I think the 1HD-T uses glow plugs.

NO.
1HD-T has direct injection,so it doesn't have glow plugs,

1HD-T is direct injection and definitely does have glow plugs after researching further. 12HT, 1HD-FT do not, but have the preheat screen instead.

Nope.
If a motor has direct injection it doesn't have glowplugs

I don't know why it is they have them Shane, given that most direct inj. diesels don't but for some reason they do. Any you can buy them too. Probably a moot point as I doubt that is the issue.

A diesel will vary rarely be fixed with new rings, usually the bore is scored from overheat and alloy piston grows more than bore size...
I paid 4500 to rebuild mine, rebore, renew everything and i did all the dis/assembly myself...maching was 2k rods closed and honed, crank linished, crack tested....u see, its not worth spending a few thousand and not doing it properly...believe me you dont want to go back and do it again....firstly, i would check valve clearances, that may be all thats wrong.
Next id be looking at that 7k motor real close, as what you remove is worth 2k if it has a good bottom end.
Oh, did i mention warrenty with that...

You Didn't mention if it was factory turbo motor (1HD-T) or aftermarket turboed 1HZ,
They have different heads to begin with.
One thing to watch for if it's a 1HD-T is the bigends, they where prone to failure.
As mentioned on prevoius post, If you are gunna go away in the future, bite the bullet NOW and get a proper recon done, I know it's easy to say!, but you will more than likely end up having to fork out for it, or spend your entire holiday worring about it.
You will do well finding an exchange fully reco'ed factory turbo motor for under $10k, other have mentioned lower prices on this thread, but that would be for a 1HZ I would think.
