#1 of 166 Daihatsu 2.8 turbo diesel - pipes snapping by guy2

Jan 23, 2005 (9:49 am)

I have one of these fitted in a Range Rover - all the diesel pipes aew well fitted and have the appropriate straps holding them in place, however, the injector pipes keep snapping just short of the injector pump. There are no heavy vibrations and everything appears tight. no 3 has just gone again after only about 500 miles of very light motoring - anmy help or suggestions gratefully received. Thnks

I'm going to change this topic to Diesel Problems so as to attract owners of other makes.
 
I'll e-mail you about this.
 
thank you

#3 of 166 injector lines snapping by Mr_Shiftright HOST

Jan 23, 2005 (1:25 pm)

Inasmuch as this is a conversion, my first suspicion is that your motor mounts are either too weak or incorrectly aligned, allowing too much rotational torque for the engine, or perhaps even too much lateral (front to back) shift.
 
Severe vibration could break the lines but you state this isn't the problem.
 
Also, if the lines were "forced" to fit the injector pump, that is, bent to be able to screw into the pump, this constant force could break them in time. I have seen this happen with say exhaust systems that are "jacked into place" to meet their flanges, and I've seen it in brake lines that are bent with force to meet their mating nipples.
 
You might ask an observer STANDING TO ONE SIDE OF THE VEHICLE, NOT IN FRONT, with the hood open, to watch the engine movement as you step hard on the brake, put the vehicle in gear and apply gas in their first or "drive" and then "reverse".
 
If there is noticeable engine rotation, that's your problem IMO.

#4 of 166 vibration by icrman

The lines will fatique from the vibration loads imparted to them. There are small tie clamps that clamp two or more lines together to form a more ridged system. If you have the factory clamps on the lines in the correct areas, and they still break. You may have to add a solid brace from the line to the engine.

don't see why not, as long as its #2.

#7 of 166 hard starting diesel by hoader

May 27, 2005 (4:23 am)

My neighbor has a Perkins 351.4 diesel non-turbo engine that has just been overhauled. It starts as if it were below freezing when it is in the 70s in F. New rings, pistons, sleeves, rod and main bearings, rebuilt head and injectors. The pump was not touched. After starting, I felt the exhaust manifold and #6 cylinder runs the hottest the earliest where as #5 is the slowest. It took over 2 minutes before it ran on all 6 cylinders. I can't do a compression test till I get an adapter for that engine. I need some ideas and tricks to trouble-shoot this one.
Thanks hoader

#8 of 166 rebuilt engine by Mr_Shiftright HOST

May 27, 2005 (7:39 am)

Well if it's JUST rebuilt with zero time on it I'd run it at fast idle for a good hour or more and then change the oil, first off. Let everything seat in. Sounds like an injector or....does this engine use glow plugs to start? If so, are they all new and are the connections good and tight?

You should cruise our Pickups board for this question:
 
Pickups
 
There, you can talk to owners of these various trucks.
 
In general, I can offer my opinion that a diesel truck is great if you are towing something heavy, otherwise it doesn't make a lot of sense with diesel fuel prices being generally higher than even premium unleaded. As for diesel engines being "more long-lived" or "easier to maintain", that is really subject to a lot of interpretation.
