TDV6 oil pumps

Sacrificing the manifold isn't much of a sacrifice as they should be replaced anyway at their age.

I’ve tried the removal tool, no joy. Tried prising it up whilst trying to turn it, no joy. So this injector is officially toast. So Ive removed the solenoid from the top of the stuck injector and made up an adapter to screw into the injector body, I’ve got a 5kg slide hammer attached to this and with as much force as I can put into the hammer it is not budging. Bear in mind it has been soaking in wd40 for the past 2 days.
What do I do?
my thoughts are, chain drill the cam cover around the injector so I can at least get the cover off and remove the head, then warm the head and continue with the slide hammer, or just go and get a head from a wreck.

Thoughts!

Answers on a postcard to the usual address please.

Don't have a postcard handy, so here will have to do. Do you have one of those duck foot bearing pullers, or any type of puller? If you can thread into the injector where the solenoid was, and bear load via the puller onto the head, you should be able to pull the injector out that way. The hardened steel threads of your puller are stronger than a slide hammer and apply constant load.

Just an idea.

Hi Andy, I see you've had them soaking in WD40 but Wurth have a product called "injector EX", it's what I used on mine when they were pulled and #6 was seized badly and it got the job done with the aid of a similar set up as you have with the heavy slide hammer.

I called in to see Andy on Sunday and the disco is alive, not without some headaches along the way which required body off procedure to fix.

So, a few months have passed since i updated this post.

The car is back up and running and has been relatively trouble free. Had a minor fuel leak from an injector leakoff o-ring and a major fuel leak from the pipe coming off the fuel cooler (by the oil filter housing) and left a fuel spill trail about 5km from home to home and up my driveway.

Anyway back to my repairs. RH head was a doddle, LH was anything but. I ended up biting the bullet and lifting the body off. Borrowed a trailer and took the car into work to use the lift. Took chassis home and finished off the work. So much easier.

I smashed the intake/cam cover off and removed the LH head. Injector still stuck in head and glow plugs all siezed too. I went and got a 2nd hand head from a 190000k Territory (should have got them both as 1 of the exhaust manifold studs sheered off plus breaking an ezout in the stud and the glowplugs were also siezed too).
Fitted both heads, new oil pump and belts etc. Assembled everything else. No dramas apart from the glow plugs in the original RH head and the manifold stud. Back to work to fit the body. Basck home for everything else.

First attempt to start took a while as the fuel system needed to bleed itself. it built oil pressure nicely on the starter alone before it fired into life.
Had a bit of an oh-S**T monent on the first drive with the oil pressure light coming on. It ended up being water in the connection shorting out the signal.
And has been fine ever since apart from the fuel leaks.
There is a bit more noise from the RH head compared to the LH, so i went ad got the RH head from the same Territory to replace over the next month or so.
Ill report on this repair soon.

Till next time
