Hi folks ,

I’ll be starting my Navara next week after carrying out the BGA duplex conversion and the cylinder head gasket replacement as was leaking from the front right corner of the head (gasket was cracked -3rd layer) .

Now as a lot has been changed , injectors have been out , fuel rail off , chains off , cams off , head off etc , what would be the best or safest method to get her going ?
All suggestions or thoughts are most welcome?

With your fingers crossed!

I would start it up normally and let it idle for a few minutes. Then stop, wait ten minutes and check all the fluid levels. Then go for a run getting it up to temperature and returning home to check for leaks and anything else you can think of to satisfy yourself that you have done a good job.

Very stressful none the less , spent a small fortune on her In this past month , BGA chain kit , blue print gasket set , Valeo water pump , new thermostat (blue print), all belts (Gates), new oil pump (Nissan) , new radiator (Nissan) , all parts are either genuine or equivalent no cheap rubbish , Nissan oil and filters . If it goes bang I’ll be highly upset ? watch this space .

Normally they are pigs to start after the injectors have come out , air in the system , do you need to use easy start to get them going or just crank it over and hope for the best ?
 
did the same work myself, and all i did after a double check of the fluids was to slightly undo the feed the feed to the fuel pump at the filter to ensure fuel was present, and made sure the filter was well bled and primed.

I think i cranked for a couple of seconds with no start, double checked everything again and she started quite easily on the second attempt.

Thanks Al I hope it goes smoothly , that’s what I was wondering so hopefully she fires up after a couple of turns

Well she started after the 3rd crank , sounds very quiet , no rattles or noises , ran her up to temp , no leaks as of yet , happy is an understatement lol , time for a stiff rum .

great feeling. like me you were likely rather nervous up until she'd been running for a minute or two. top job!

So stoked , best feeling haha
 
Good stuff hope it goes well , let us j ow the outcome , how much were the injectors ,mans do you have to decode them ?
Not sure on a price yet, but we are going to try and get a set with the same code so I dont have to muck about with a tune. Unfortunately my truck is at home and I'm quite remote, so getting it to the dealer or getting someone out could be expencive and difficult.

you wont get a matching code. Each code is unique to the injector since the code is just calibration details specific to that injector. The code just tells the ecu how much to alter fuelling by for that injector. Arguably any higher mileage engine, even with the correct code will be slighty out when it cruds up or wears, and swapping around injectors adding new without coding wont prevent it running. Even coding second hand injectors wont be bang on. Best to get them coded at some point though, since you obvious want to be as optimum as possible for DPF's/Cats and general fuel consuption. Not a major issue though.

The system was put in place to keep the costs of injectors down. It would be far less practical and more costly to adjust/manufacture each individual injector to suit an exact calibration held in the ECU, so its easier just tell the ECU to adjust to the injector.

So I did about 100km today, the truck ran like a dream, plenty of power, still havent given it full throttle yet so i think i should be impressed when I do. I managed to get a real sharp deal on the injectors, so I'm not completely gutted with the 9K I've spent on parts in the past year. I recon I saved myself about 5k by sourcing the parts myself and doing the work, although the stress levels have definately been up a bit ;-) Lets hope this is the last breakdown for a while.... it was definately a friday truck....
