As above guys;

When Iv'e rebuilt gasser engines in the past I've removed coilpack fuses or similiar to prevent the engine firing on first startup so I can build a little oil pressure (on a newly built engine)

Whats the best way on the ABL derv engine? I know my T4 doesnt have an ECU, so whats the best way of preventing her firing up (if indeed she does fire!) when I crank her over tomorrow hopefully.

I was thinking of removing the glow plug relay but that doesnt guarantee a non start (I dont think...)

thanks

take the power off the fuel pump shutoff solenoid while your cranking.

a long bolt with a slot cut in the end to prime the oil pump and the rest of the engine...chuck the bolt up in your trusty cordless drill...take the vacuum pump back out and engage the oil pump with the bolt...spin your drill up until you get some good PSI reading on your gauge....now go crank the engine for 10 mins while the fuel fills the IP :lol:
that's how I did it..

Wheres that found then?!!
the fuel pump shutoff solenoid that is

the fuel cut off should be one of 2 wires going to the pump. one is the fuel cut off the other is for max fueling under boost ( if fitted on your model ) anyways just unplug them both and you're in buisness.

If you had the the injector lines off, you will probably have allot of cranking, and hence adiquate oil pressure, for you first start.

If the injection pump is dry, you have a boat load of cranking befor it sucks the fuel from the tank.

Thanks guys

As a sidenote on why I was having a job setting the timing back up.
I had removed the injector pump pulley and replaced the 3 bolts and pulley in what I thought were the same place (a month or so ago)
Clearly, they werent in the same place :lol:

I only remembers that this afternoon when trying to get it running again so I loosened the bolts on the pulley and she timed up a piece of cake. Then I retightened the 3 adjustment bolts.
Note to self - Dont leave stuff so long

I primed the turbo motor I'm building yesterday just to make sure oil was getting to the head and such, I used an old screwdriver with a slot sawed in the handle. What amazed me was how much oil goes to the turbo. I can see now why a tight unrestricted drain line is so important. I never messed with any tubo stuff until this engine and I can see how a leaking turbo seal can make you use so much oil, I hope this rebuilt turbo has good ones in it, supposed to be Garret but you never know nowdays.

I actually use a little socket adapter in the drill and a 13 mm socket that has a little extra ground out of it. It works incredibly well, fast, easy, etc..

Weird, I just did that a few days ago and I didn't have to grind anything. Only I used a speed handle and could still get 70psi, I can't remember which way to spin it, but you can feel the pressure building.

IF youre wanting to always prelube the system at startup, look into getting an oil prelube pump from engine savers. It pumps oil out of your oil pan and runs it through the engine an turbo for 30 seconds before startup. It also runs for 6 minutes on shutdown to help everything cool off.

Someone I worked for just gave me a brand new unit, im debating on installing it on my truck or in the car.

amsoil makes a pre-oiler AND bypass filter all in one unit...get your check book out tho!!
