wow I think thats the first time Ive had a cross over on the forums !! cheers mate!
ok I´ve got another question for the experts please.
When starting the car (new battery) it seems to take forever to actually crank up.
I´m not sure about the state of the diesel heaters
. and when it does start it dies unless I keep it on full throttle for about 3 minutes
. as if it needs the engine to be warm for it to tick over.
I´m thinking maybe one or 2 of the diesel heaters are knackered ?, and would this affect the power problem when the car is running.
not sure how the diesel engine works apart from what I´ve seen on you tube.
are there any links on here for my engine problems. and lastly what is my engine and which car is it from??
thanks guys and sorry for such naivety!
As you hinted, you have 2 separate problems.
The starting should not take several turns of the engine unless your compression ( for different reasons) is low (should be 18bar, I believe).
What you call 'diesel heaters' are called glow plugs.
They only help in the starting process.
The original (loop) type need to glow for 30+ seconds even in warm climates, when the engine is cold.
You have another loop next to the ignition switch which indicates if your 'system' is working. That loop needs to be glowing orange for 15-30 seconds. (You know that the glow position is just before the starter contact position on the same pull switch ?)
The more worn the engine the more helpful it is to glow longer.They are wired in series, and if one is bad they all won't work right.
They need to have a certain resistance (?4 ohms?, you can search for details here above)
The newer glow plugs (commonly called pencil type) are wired differently and are connected to a glow plug relay. They glow a few seconds, depending on motor and weather temperature.
Now for your running issue.
No 1 most important fact is that diesel run on compression and generally air (too much or to little) is keeping it from running right.
I would start with bleeding the diesel system from ALL air !!.
There is a bleeder screw on the top of the fuel fine filter, where you need to bleed air by pumping diesel with the screw on diesel hand pump (on the driver's side top of the injection pump). Just like on brakes: watch for air returning (close screw) in between strokes of the pump.
The lever for the little hand pump is screwed into the I.P. and needs too be turned counterclockwise to open (sometimes they're really tight).
Pull and push it up and down, repeatedly (about 10-15 times). It needs to pull the fuel from the tank all the way up to the motor.
There should be some fuel in the line and you should feel some resistance.
After 15 times: If it sounds like it's just sucking air, then it probably is, and needs replacement.
I'm not sure if the newer ones from the w114 or w123 fit on that I.P. or not.
You may have a brittle fuel line (If original cloth wrapped fuel lines , then you can hardly tell) that leaks or just sucks in air (fuel out or air in).
Watch for the tiny injector return lines. If the motor starts running well they may leak too and air comes in through the return line....
I hope this helps for now
Why don't you throw in a you tube video of how you start it and how it runs, if none of the above helps any...
