will try that and see. I use it in the bore for installing the pistons with the new rings on a rebuild.

Sludge to keep your engine sealed???Not for me.An idea might be to use an engine flush and change filters very soon.Some synthetic rep for causing leaks came from oil manufactures reducing additive packages to keep costs down.Premuim modern synthetics have more seal swelling additives than dyno so should be less likley to leak.I use synthetic in my vehicles and would not use anything else.Dyno oil in certian toyota engines is notorious for producing sluge.Dyno with it's unstable base stock contains molicules of various sizes .The lighter ones tend to boil of at high temps.Concentrating the remaing oil channnging it's lubricity characteristics and it's ability to deal with buyproducts of combustion.My 2bits

Stephen, cheers mate. I missed the point of the sludge sealing the engine until you pointed it out.That s*** is lethal,drops oil pressure,restricts the oil intake,makes the hydraulic lifters stick.And gums up everything until failure.My lads sump had app 1/2 an inch of thick sludge in the sump .Have not had to worry about leaks though this would happen on an old engine especially if left standing for extended periods.cheers
By Dyno do you mean mineral oil or semi synthetic ,

i plan to turbo my 1HZ within the next 6 mo and will probably do BEB's as a precaution. the replacement bearings have been upgraded from the orginals right....? I am considering ACLs too.

HiVerm, from going through that post it seems to be the bearings they used up until 1995.Seems quality bearings should solve the problem.cheers mate.

ATF .. ? you mean, add 1 litre of ATF fluid to my 2H engine and run ? ( usualy I use 20W-50 Castrol mineral 11 botles )

yep, do this about 100 km before an oil change. ATF has detergent in it so it cleans the passages...
works good
cheers

Toyota Australia reccommended Castrol RX super or Turbomax for the 2H.10.7 litres with filter 9.1 without changing filter. The ATF has a high amount of very strong detergent. Will need Crusher to give advise about this on very old engines, might clean too much carbon from around the rings.Not sure.

Though there are reports of even 1HD-FTE bearings occationally showing the same flaking...
Even if the new bearings have been reworked they are still tin/aluminum afaik. I recall reading somewhere (WJM link on the DTLC within in the last few years) about Toyota wanting to meet a pollution standard, and using tin/aluminum instead of copper/lead...
ACL's are the common name mentioned for the non-Toyota replacement bearings.

i highly doubt it will remove carbon but it helps in removing sludge...bigbrowndog said:

once these bearing are replaced i will still recommend a semi synth for my customers...
the oil is the life blood as we all know so why scrimp?

Anyone read through most of the posts on the site below?

There is also reports of defective crankshafts,either out of alignment or as some believe,the crank is too light weight and flexing.
Some owners claim they had their crank replaced with one that was noticeably heavier.
Ive only seen one case of damaged bearings in a HD-T
The poor old HDJ80 was driven at 140klms+ for 2 hours towing a small excavator on tandem trailer.
Within a week it had the dreaded tick tick tick and some bubbles in the coolant at 200000 klms:sad:
