Ouch :(
Theres a good one out here in ipswich...
I've sent stuff to him before and not had any complaints back about the work....
its cheaper if you have most of the stripdown work done in advance. I'll try to track down his number and PM it to you...(thats a hint to send me a reminder in a few days if I forget to.)
Theres a couple of diesel shops a bit further abroad that do diesels as a specialty but wont pull the motor for you (conveniently one of them is located next to a mechanic who will and you can arrange for a tow in drive out end state.)
Bugger. The worst has come true.
Did you try and measure the piston height, as I tied to explain in one of my previous posts? Number two looks like it has had a hydraulic lock and has bent its conrod. But ! it could also mean that a push rod and/or valve stem is sticking, much easier fix. So before pulling the head off, check the valve clearance settings and do that wire test measurement down the glow plug holes, --- again, you will need a set of mole grips, a stiff wire and your feeler gauges.Quote:

Insert the wire down the No 1 glow plug hole, until it touches the piston at top dead centre, with a feeler gauge blade between the head and the mole grips clamped off then try the other cylinders, if number two conrod is bent then the wire won't reach the top of the piston using those settings
By having the injectors removed and spinning the motor over, should blow most of the rubbish out.Quote:
Now this test was not a true indication of the cylinders, but a reference of each to the others. There is no way of knowing how much oil/fuel is in the bores due to the incident and all the starting attempts. (creating ring seal) Gauge was a brand new snap-on (including hose and fittings)
Doesn't the fuel pump keep circulating the fuel through the IP when cranking the motor and the solenoid is off ? undo the pipe at the filter that goes across to the fuel pump.Quote:
All 4 cylinders were tested the same, except I did #2 twice. I had the engine turned over for approx 6-8secs. This was enough to see the gauge rise , rise and level out. Once peeked, I would keep it turned for a few more revolutions(within the 6-8 sec) I would have turned it over more for each cylinder but the diesel was being pumped out.
Which leads me to my next :confused:..... I had the wire removed from the back of the IP. Fuel was continually pumped and appeard to mostly be coming from the banjo bolt on the return spill line. All or there abouts, out of cylinder #1 banjo bolt. After the 4 cylinder compression tests it must have pumped 3 or so cups of diesel out.

Dave, I thought you did all your own work :confused:
Arthur, Im getting to the point were its going to be better in professional hands. Time is ticking and I need it to get moving into repair mode. Regardless of the valve or rod I want the head off and at least a visual inspection of pistons and bores etc.
with regards to the IP: Im not sure of how they function, but was under the impression that if the IP solinoide wire was removed it would stop delivering fuel to the injectors. I figured there would be a little fuel left inside it and the rails, But this continuied to pump during all the tests. I did have it in my mind that the lift pump would keep pumping due to the fact it is mechanical and works of the cam shaft. Someone can fill us in?
The worst has come true, bugger. Most likely a bent conrod as discussed.
Since you are spending the money Serg, you may as well spend the few extra $$$ to have the pistons and conrods balanced.
Hi againQuote:

When I read this I asked him about what you noticed with the fuel coming through the injector pipes, Yes that,s right but with no pressure available.

Hahaha, someone was mentioning this on the phone at about the time you posted this :DQuote:

.... and a big thanks to uniformed (Serg) :thumbsup:! It really sucks that you're going through what you are, but you have my complete admiration for openly admitting your mistake, remaining positive while working through it, and also keeping the thread so up to date with such a big issue at hand. I couldn't do it.
Well done everyone!
James.
yes a big thanks is desevered to those that have helped. Thanks :)
The tilt tray is booked for 7am tomorrow to tow it to the mechanic. I will keep this thread updated as more info is found. I will be interested to see what damage has been done :confused:
If I had the time/money/space etc I would have a go at it myself for nothing other than to learn some more.
On a similar note, I was speaking to a mate today that us to be in the LR game. He was telling me of a recent lift pump failure in a workshop he knows. The pump had a split in it leaking fuel into the crank case, they were not aware of this. The engine was running in the workshop when it ran away. They choked the air intake and stopped it.
