Good morning all, after spending ridiculous amounts of time and resources I an getting close to finishing my Navara project. It is a 2008 2.5 diesel 4x4 D40, Thai spec. Now I have come across this little box. There are wires coming from the ECU into this thing and for the life of me I do not...

I agree. My problem is they are pricey and I have spend more than I should have trying to get the original engine up and running. At this stage i feel like a box of matches will be a perfect fit. Fir me to fork out another 50K on a motor... eish not sure it is worth it

I brain is working overtime to solve the problem my apologies. I am looking at the hardbody np300 2.5 diesel. Year model from 2010 to about 2013. It is fitted with a yd25ddti engine which from all my searching seems to be the same motor. Common rail injection setup, the intercooler being fited...

Good morning all. After endless battles with my current engine I have given up. I am sure this had been covered somewhere but I cant seem to find any info. I have a navara d40 yd25 2008 model. My question is will the yd25 from a np300 fit and work as replacement for my current engine or is...

hi manual 4 x4 model. Thai spec. my theory was or is either oil level is to high and therefore oil is pushed up through the breather pipe on tappet cover. I cannot think of any other possible reason for this. originally did a compression test and the compression was below spec. replaced with...

Good morning all. I posted a while back some issues I had with my d40 YD25 . It is a 2008 model. Redid the engine. New bearing, Pistons, rings . Etc. Also new turbo. After failing to start I replaced the head and 1 injector that was leaking. The other 3 was refurbished about 500km earlier...

Wil check the glowplugs when I do compression test today to see if they are wet

The EGR is blanked off on both ends. I will check the airbox, did not replace the air filter as yet, intercooler I cleaned out and just a mention that I did replace the turbo also, checked the cam position sensor as the old one was faulty and found the red wire had broken off and soldered it...

Good evening all, I know this topic has been covered in the past but I cannot find a exact match to my problem and need some expert advise here. I replaced the head gasket due to an idiot who rebuild the complete engine and used the wrong head gasket. With this I had to replace 1 piston. Also...

I looked at it. Actually not bad if all the gaskets are part of the deal. I have send them a message as they say they do not ship to South Africa. Hopefully they can make an exception.

Ok so I have taken the head of and measured the piston protrusion with a dail gaudge. It is at the limit of the head gasket with 6 notches. Whilst checking everything I noticed something. On the head the valves are actually protruding past the flat surface. Not much but when it comes to...

will it be possible to pull all the pistons out without removing the engine. so will I have access to loosen all the big ends and push the piston upwards from beneath the bakkie if I remove the small sump. picture attached I am alone in tackling the job and pulling the engine will be my last...

I did forget this part. the timing was out with 2 links on the chain running from the crank to the middle of the engine. the 3 top pulleys lined up with the links that are colored but obviously the bottom linked being out would have contributed to the problem

I think the head has been machined a couple of times and when the mechanic assembled the engine did not take this into consideration. I did a pressure test after installing my own manufactured gasket(2.5mm thick) and the pressure was consistent although below recommended spec, reading was at...

Good evening guys. New to posting on the forum. I have a Navara d40 yd25 2008 model with endless issues. I have watching and reading comments on the forum and there seems to be a lot of guys out there with notable knowledge. I have a question. I need to replace my nr 3 piston(if counted...
