Ray,
I don't think there is anything, the only way to really fix this is to degaze the bores with a honer, as far as I know. Then when you start the engine again make sure it's loaded as soon as you drive it, I towed a loaded trailer up a hill about six times as soon as I started the engine up, this helped. This is what I've been led to believe.Keep the shiny side up

A hand full of Bon Ami in the air intake will deglaze it.

Ray,

The advice given to me, by the service manager of north west qld dealer, was a handful of Bon Ami, down the intake. I laughed, so did he, but felt he wasn't speaking in jest. Feel this was their modus operandi, takes 10 mins, charge 8 hours.

There's a mob that advertise a service to bring glazed motors back to standard, think it's in 4WD Monthly. Hooroo...

I used to work for Lincoln Electric and a common problem with Perkins diesel driven welders was glazing of the bores. Persil down the air intake used to cure the problem.

Any abrasive substance you pour down the throat of your engine is going to do the job on, cylinder bores,piston rings, valves and anything that gets past the rings will find it's way into the oil and then the bearings. A great way to completely stuff your engine, top to bottom. Do it properly or not at all. Lift the head off and have the bores deglazed by a professional cylinder honer, who, if he knows his trade, will measure the bore for excessive tolerance to see how much lee-way he has got to work with. It might be that the wear is excessive and no amount of deglazing is going to substitute for metal already worn away. You may not want to hear the results of his measurments!

If the motor has only done 2000klms.... take it back to them, and tell them to fix it - Free...

They couldnt be that jewish to rebuild a motor and NOT hone the bores, after all it takes around 1 minute per bore.. WOW SIX MINUTES.

Small claims court, Consumer Affairs would also help.

Something doesnt gel with all of this.

i agree with desert any of that stuff is abrasive /might as well drive arround with air cleaner off[ probably do less damage]

whats the problem -tomuch blow by-oil burning/may be turbo if fitted not set up properly. in my opinion 2h is not suitable for fitting of turbo unless you fit mech governor pump as well. a lot of pressure from turbo gos down balance tube on venturie via pumps and into crankcase. these engs breeth afair bit normaly.
glaze is usualy abuild up of varnish etc on cyl walls.we have removed this succesfuly on petrol engs with agood detergent/just pour into cyls 2 at atime let soak clean out and sqirt crc or sim to stop rust .can be done with head on . we use nth power deturgent.
however if your eng has only done 2000k since rbuild should not need deglaze take
it back to the rebuilder/ if you fill it with bon amy or any other abrasive it will be a way out for the rebuilder

Glazing is a symptom of some friction modifiers in oil. (teflon may have been one of them)

Years ago when friction modifiers first became popular in motor oils many engines became glazed. We ran a fleet of vehicles and had some problems with glazing and after some homework found that among others Penrite oils will deglaze a motor as they do not use friction modifiers and use a slightly different lubrication and cleaning principle. It allows just enough wear to prevent glazing. (but I bet your engine will outlast one run on FM oil)
(I forget the exact details)
If anybody can add to this please do - Needless to say Ive been using penrite ever since and havnt had the problem.

I must say it certainly will keep you engine in great condition. (both sludge and glaze free)
Toyota dealers seem to use an oil that leaves deposits on motor interior surfaces check your dipstick chances are theres a brown residue halfway up the dipstick - dont know if its related to the glazing problem as well but I noticed it on a petrol toyota celica I bought that had been serviced by toyota all its life - it dissapeared after a few months with Penrite in the donk.
I dont know the severity ray of your problem but as for the ajax trick - I worked with diesel field mechanics in victoria in the 70s and it was a great mechanics joke - it worked - but also kept them in business.

Ajax!!!!

I had a petrol motor once that was using a bit too much oil. My cousin said pour a bit of ajax down the carby and it will help to rebed the rings.

So I did.

I reved the the thing as hard as I could then watched the motor cough its way down to almost stall as I regulted the ajax down the throat of the carby. The treatment went on for about 5 minutes with the motor picking up revs to about 5000 then back down again as the Ajax went in.

After the treatment the motor used so much oil that I could not drive it and still see out my rear view mirror. I wrote the car off and did not drive it again.

And gues who ended up with the wreck - My Cousin....

You say the motors been rebuilt 2000klms ago, new pistons rings etc, yet they didnt hone the bores? What sort of hacks are they?

There is no way on the planet it would glaze up in 2000klms.

i dont know wether i supposed to advise companies on this forum but may i suggest talking to Cost Effective Maintenance (www.costeffective.com.au).
Ihave trialeed some of their pruducts to cure glasing and severe sludging of a 3.2l Jack engine, that my mechanic had apart to replace shot hydralic lifters. He found severe sludging in all oil chambers that he literally had to shovel out.
Also discovered that the lifters assemblys had suffered premature wearing,due to acumulation of sludge blocking critical oil passages.The rattles have disaapeared somewhat with new lifters but unfortunatly will always have some until i replace the whole rocker assemblies.

Since been put back together have trialed some of this pruducts to alleviate these problems and have found definite improvement in oil presure and engine performance.Also have a 2wd hilux which is very good condition and after posiitive responses in the jack ,used in the hilux. Again a very noticable improvement in engine and gearbox performance and distinct reduction in engine noise.

I also recommend the use of penrite oils .I find these oils deliver exactly what they promise and since using them found things seem to stay cleaner and operate more effeciently.

Hi Ray
Having read most of what has been posted to your request I have some words for you.
All the talk of different oils does have some validity, there are some engines that just do not run well on some oils. i sugest you run on the oil that the manufacturer recommends they spent a lot of money on the research.
If you engine has been recoditioned and new rings fitted without the bores being honed this would be!!! not in the normal practice of doing things.
Any good long drive after a rebuild will bed the rings in, just do not let it idle.
Do it properly do once
Hope this helps Ray

Any decent engine rebuilding mob should have told you how to run the engine in.If you can get on a dyno give it a whirl thats how they run in heavy diesel engines before delivery
