High kilometres or something > more nasty?. > > Ian B Hello there Ian you were right about your definition of the short motor I got the new short motor under warranty from Toyota, I wasn't happy with the oil loss with my original engine ( at worst 3 litres per 5000kms lost )and Toyota agreed to replace the motor at the end of my warranty period. Which was 3 years or 100 000kms My vehicle has 86 000kms after the 3 years. It was thought that my motor was losing this oil via the blow by and at one stage they adjusted the oil baffles as they said it was set at 90 deg instead of 30 deg. This seemed to improve things for a while but it started to lose oil once again. I know others with a 1 hz motor with 200 000kms whose motors show no appreciable loss of oil so you can understand my concerns. I also had my injectors serviced recently from an injection specialist, they told me my injectors were incorectly set at a low pressure, which he said in turn would have unburnt fuel washing down the cylinder walls and possibly creating a glazed motor after time. So maybe this was a contribution to my problem. Or maybe it was because I ran my vehicle in as per the handbook. Take it easy and don't keep at a constant speed. Its very confusing as I certainly want what's best for my new motor. And I do appreciate Toyota coming to the party and giving me this replacement.:))) Graeme From: "Ian Staines" To: Subject: Re: [DTLC] run in advice Date sent: Wed, 19 May 1999 18:45:38 -0700 Send reply to: dtlc@helios.net Another tip is to vary the RPM over the first while. Never drive solid highway RPM's for a long period of time, or long idle RPM's either. The connecting rods will stretch and compress at the different RPM's and this changes the range that the rings travel up the sleeve. You want to be sure that they seat well along the entire range of movement without any ridges forming.

Basically Graeme got a >new block/crank/pistons/bearings/seals. In this part of the world we call it a "short block" and it is exactly the same as described above :-) >Ian you were right about your definition of the short motor >I got the new short motor under warranty from Toyota, I wasn't happy with >the oil loss with my original engine ( at worst 3 litres per 5000kms >lost )and Toyota agreed to replace the motor at the end of my warranty >period. >Which was 3 years or 100 000kms >My vehicle has 86 000kms after the 3 years. I am glad Toyota did right by you :-) After all you spent a lot of extra cash on oil ! I have heard both sides of the story (for proper engine "break-in") too so I am sort of confused too ! I known that if I bought a new vehicle I would follow the advice of the owners manual (which I am sure the majority of people do) this way you can rest assured that "you" are doing what is supposed to be the "best thing" for your truck I know that after rebuilding my 2L engine from my Hilux I drove it normally (which means I did NOT baby it) but tried to vary speed for the first 1000 kms It did consumed a little more oil for the first 5000 kms but the oil consumption is normal now One thing I did notice is that engine temp seemed to run a bit too high for me to be comfortable with specially under load !!! We have a 7 km hill that I have to climb every day and this is where I noticed the temperature increase But now things are normal when climbing the hill :-) >I know others with a 1 hz motor with 200 000kms whose motors show no >appreciable loss of oil so you can understand my concerns. Sure can !!! this also proves that a "normal" HZ motor can run trouble free and I am sure a good majority of them were "broken-in" as per manufacturers intructions >I also had my injectors serviced recently from an injection specialist, they >told me my injectors were incorectly set at a low pressure, which he said in >turn would have unburnt fuel washing down the cylinder walls and possibly >creating a glazed motor after time. >So maybe this was a contribution to my problem. That IS a very good possibility !!! In any case it is unfortunate that you ended up with an engine that was built on a friday afternoon or a monday morning :-( >Or maybe it was because I ran my vehicle in as per the handbook. >Take it easy and don't keep at a constant speed. I would bet my bottom dollar that "this" had nothing to do with it ; in fact it should help >Its very confusing as I certainly want what's best for my new motor. Speaking of help and what's best for your engine......... Now would be the best time to help your engine with one of the following : http://www.enginelube.com it is a bit pricey but I built my own with a 12 volts agricultural sprayer pump (not as heavy duty as the one shown above though:-() Or if you feel adventurous and handy you can build your own "sort of" preluber without a pump !!! These guys have the full "do-it yourself" procedure if you want to do it yourself !!! Just look at *free plans and parts list* Check out : http://www.prelube.com/ BTW I found out about these web sites from another BJ 70 owner that I hope will be joining us soon on the diesel list if he hasn't already, Robert Houde are you here yet ?
