Landcruiser V8 Engine Overhaul

Fit a speedy sleeve kit . In case damage to crank etc . I use a self tapper to remove old seal . Sometimes damage is done to alloy outer housing when replaced . https://www.skf.com/au/products/industrial-seals/power-transmission-seals/wear-sleeves/skf-speedi-sleeve seems they are after more work ? Yet they couldnt fix this ? Check blowby and crank case ventilation? Adding more wont hurt !!

Crank ventilation etc already covered. Seal installation by previous workshop is suss and gearbox needs to be removed to find out who or what is the problem.

"After more work?" Nah! They give me options, I make the choices.

I'm no Landcruiser expert. but unless it is really bad I would not be to worried about it in the near term. there are plenty of cars out there that have been running around with leaking rear seals for years. Car manufacturers always used to leave a hole in the bottom gearbox bell housing to let any oil leaking from the rear main bearing drain.
As Aus-Kiwi has said I would certainly be investigating possibility Speedy sleeve and a new seal before an engine rebuild if the car is otherwise performing alright.

I would even fit a vacuum pump to run crankcase under vacuum . About 5 to 8lb . A roll of carpet tied under bellhousing to absorb oil and pass pink slip? Try mineral oil ? It helps keep seal soft !!

Rear main seal restorer, claims to be excellent. Usual disclaimer.

Hmm I believe this is not a helpful comment considering the OPs situation. If the previous repair was done badly then a bucket full of risone in the engine will not fix it.

It might be suitable for an old engine with a lot of Ks and a slight leak possibly but once you put it in you need to keep adding it at every oil change to be effective. Seal restorer is a gross overstatement and should really be called a seal rubber sweller. But it will not put the worn lip back on or fill the shaft groove. All the other seals will swell too which might be OK in an old donk and you get through rego again more easily !! aww

I have used additives when I though they were appropriate for a short term fix but never expect miracles and have never observed any either disbelief

I agree with you Jaahn.....there are no "magic fixes..." Pull flywheel off and seal out and have a look ...."a seal saver.." may then be a good option .Generally work well and are a very cost effective option if there is shaft damage.

G'day Snippy - rebuild for the v8 "I am told to expect $15-20.000 bill for a rebuild." seems the norm. Our old 80 series 4.2l 1hZ was at $16,000 after 420,000k. Hence it was sold off and we got our Discovery 4 which of course was nearly double the rebuild @$30,000.

Hello Snippy,

Just a suggestion.

Before you commit to the rebuild, ensure that your engine is breathing correctly.

Do you have an after market catch can fitted, sometimes these cause the engine to build pressure inside the crankcase, placing pressure on the rear main seal causing leaks. This link refers to a similar problem - https://www.youtube.com/watch?v=44cIVBsBKYQ

Does the engine have a pcv valve, if so, is this working correctly, if not the same symptoms can occur.

Usually a rear main bearing that is worn sufficiently to cause the seal to leak, will exhibit other symptoms, are there any noises that sound like worn bearings "knocks" etc.

Hope this helps.

All is revealed.

After removing the gearbox it became clear the the seal and the timing cover were both damaged by the person who did the last "repair?)

Lubemobile have now paid for the work under warranty, but wait: There are no rear timing cover parts in Australia and have to be ordered from Japan. Told could be up to 10 weeks.

So, we are stuck in an out of town caravan park with no car.

How can be that parts for a top selling 16 year old car are not stocked in Australia?

What legal recourse do I have here?

We had a similar problem when we were in Coffs Harbour ,Toyota told us that there was no hoses for our 200 and we had to wait weeks to come from Japan.But SWMBO (who used to work in the car industry) got the part number from Coffs Toyota and rang around and within a day had the parts shipped from Brisbane.So I would be tryin to get the part numbers you need and start ringing dealerships around Australia yourself,it's just ridiculous, the amount of 200 series in Australia and the amount of dealerships I would be doubtful that none of these parts are in Australia , good luck mate .

16 year old car and no spares. That would be right. This is why insurance can often be dearer for an older car than a new one. Spare parts are hard to store due to the multitude of new models every year. Covid is causing major headaches for most business,s around the world. Thats why second hand car prices have sky rocketted. As has been suggested..ring every dealer in Oz...chances are someone will have a part sitting there. Good luck.

Hi Snippy,

The aftermarket spare parts business in Australia is very large, the seal will be readily available from other sources and will be exactly the same, what other bits do you need.

Try this company for a start - https://www.terraintamer.com/en/

Hope this helps,

Bob

Re my above post, problem solved, not the crankshaft, just shoddy repair work in bearing seal.

There was a law covering this where any importer of foreign vehicle had to stock all parts before they could sell the vehicle, however it was also time limited I think 4 years but don't quote me on that, I did a cam shaft in my bike many years ago and the importer did not have any in stock and had to air freight it in from Japan at his cost and supply me the use of another bike while I waited, laws seem to be greatly relaxed where big companies are concerned these days so I don't know how the law reads now.

Exactly damaged cover . Can be repaired !! Not saying to weld a crank ! Btw thats what Speede sleeves fix also ! When theres damage to either surface !! Timing belt ?? So its the FRONT crank seal ? The gearbox is not there !!

Whatever, the cover is on the rear of the engine. No warranty if plate is repaired, has to be new. Also, cheap patchups no acceptable on my car.

The timing cover is on the front ! When fitting these alloy covers fit seal BEFORE tightening bolts so cover is centred by seal ! Btw alloy welding is not a bodgy repair ! .. They have the kit in Repco Nowra ! Are these guys fitters or mechanics ?

So it's not a timing cover. I am not a mechanic and have no intention of ever being one.

THe part is on the rear of the engine, is stuffed and has to be replaced. Could not give a stuff about what it is called.

As I said previously, the problem will be fixed when the needed part arrives. I don't give **** what it is called, as long as it works. AND, I am not paying for it, the bodgy outfit that screwed it up are.

As a mechanic,Graham has simply been trying to help you,Kevin.However,when you start talking about removing the gearbox and noticing that the timing cover was damaged,it is difficult to offer assistance,since these two parts of the engine are at opposite ends of the block.(Work that out!). Bit like visiting the dentist because you have a sore toe. Graham's advice always is good,but you can no doubt understand that,unless he knows what end of the engine is giving trouble,it is exceedingly difficult to offer assistance.Cheers
