Ermmm.... I have never taken that much notice what my bj40 does to the gallon, but seeing that I have not given it much thought indicates that it is not that bad at all. I don't think the word bj40 and performance can go together. It certainly is not underpowered but you wont go anywhere fast. I quite happily potter everywhere at 50-55 and I seem to remember hitting 70 once but its the stopping that puts me off going that fast. Engines seem pretty reliable and have had no problems in 2 years. For me I love it. I like the experience of driving something that takes a lot of driver input to get from A to B. Would like to drive a petrol version but would not want the running costs. I drove from Southampton to the Midlands the day it arrived and I used less than 3/4 of a tank. I remember being surprised.

Hi, I should start a new thread but roscoFJ73 seemed to know lots about the diesel engine so I thought I would carry on this post.

I think I may have semi seized my engine today. Its been sat for over a year and today I filled up with new oil, started it up, left it ticking over, came back 20 minutes later to a dead engine and it would barely turn over when I tried to re start it. I checked the dip stick and it looked like the oil had gone no where.

what has happened, how can I fix it and how can I make sure it does not do it again...

My poor BJ

"the oil had gone no where" Confused

Are you saying the oil had not moved around the engine?

You should never leave a diesel idling at slow speeds for long and certainly never unattended.

Do you know what the oil pressure was like before the mishap.
Did the engine feel abnormally hot?
You said its barely able to turn over,could it be the battery?

Hi roscoFJ73,
Rodger and I had had things in bits today. First we took out the injectors. It turned over a little easier but something is not right, we put some diesel and turned it over, the last cylinder kept puffing out smoke??? we then took off the fan belt to see if either the Alternator or water pump was playing up/seized and there was also a squeak coming from somewhere when turning over, the squeak still was present even with belt off! Eventually we took off the sump, nothing stuck in the oil mesh but after taking off the big end bearings there is some wear marks and same again on the main bearings so it looks like engine out and a bottom end rebuild. I have a spare engine which if Grenade can let me know if it was a runner I shall put in so I can use the truck over the summer and in the meantime get the crank bearings done etc and give it a well deserved overhaul. I have no idea how many miles its done but it has spent 30 years in Australia so it probably a fair few.

Out of interest why can you not leave the engines Idling for long?

the truck was not hot when I returned to it and yes the oil did not seem to have flowed around the engine, it was still clean as a whistle. But after turning it over today it has now turned dirty as expected. God knows but Rodger was saying that the scoring on the bearing shells can cause the stiffness of the engine so thats the plan.

The scoring does have metal pick up not only on the big end shells but also on the mains, although we didn't look at everyone as the damage was sufficient to re-assess the gameplan.

from recollection of driving petrol FJ45s in the Middle East years ago, around 12-15mpg in allround use and around 8mpg in 4wd
