My 4th injector is leaking from behind the black plastic housing on the top. I have replaced all the leak off pipes as number 1 and 6 were leaking too

I have just spoken to a bosch specialist who tells me the 4th injector is not a serviceable part so will have to be replaced but have just read this on a omega forum

Hi john. I repaired mine, and here's what i did:- (The injector needs to come out of the engine). There are two retaining pins that will need to be removed, (they are a push fit into the injector body) Using a small cutting disc (eg a dremel) carefully cut a small notch into the upper part of both pins, then you can use a small chisel/screwdriver to tap the pins out of thebody. Very carefully prise the black plastic part away from the body (mine practically fell off), be very careful as the wires for the snesor are very fine and delicate. Next, clean the diesel from the injector and the plastic part finally using an evaporating solvent so the surfaces are completely free of any diesel or solvent residue. Next, glue the two parts together using an epoxy adhesive (araldite), replace the pins to hold the parts together while the glue sets. Mine has stayed leak free since I did this over a year ago. Finally, a good idea would be to check the resistance before strip down and after repair to ensure the sensor wires are ok after the repair. Hope this helps.

Any advice about what to do would be appreciated especially about how to avoid spending over £200 on a new one!!

Get a new injector don't bodge it up.
 
worth a punt but i would make sure a local suplyer has one in stock and you have the avalible cash just in case it all goes pete tong
 
Can I stick a normal injector in. I understand the ecu will stick a warning light up but will take a value from memory. At least I will be running again without a leak!
 
you will burn more than you leak due to the ecu going into fault and you will be masivley down on power

You will get more than a warning light doing that, number four injector controls injection timing if the static is out it will run like a bag of bricks.

shop about! i got mine from a mate at the back door of a well known motor factor for £50 but was quoted £140 at the front door still better than your £200+

Yeah but not everybody has a thieving mate do they. Not really something to put on here unless you want his and your collar felt. :D
 
Agree 100% there!! Shop around and don’t be afraid to aim low when bartering!

So far I’ve had new or unused

RF receiver for £35 (From US guy bough wrong frequency)
Fog Lamps £27 Pair
Tail Gate Check Straps £10 Pair (Although I have not fitted them as I have now misplaced them in my garage)
Injector No 4 £32 (for when mine eventually goes, couldn’t say no at that price)
 
Just a quick follow up. Worked a treat. The way I found to test it was creating a vacuum using the two return pipes. Put a finger over one end and suck through the other. If you can't create a vacuum you've got a leak. Remember to coat everything including where the wires come out

Oh. And the laser cut out 27mm socket doesn't fit. The walls are far too fat. Took a lot of bench grinding!
 
Well done :clap2::clap2::clap2:
although I would as soon as finances allow get it replaced cos it will eventually desolve the araldite then leak again

Did you remove injector with manifold in place then. Should fit with manifold off.
 
Will keep my eye out for a reasonably priced one

I stripped the inlet off for a lot easier access. The socket is way too fat so fouls on the cylinder head. I have a draper one but doesn't have the cut out and the walls are a lot thinner. I just kept grinding until they matched.

The only other point us that the cut out isn't high enough. I nearly sliced the wire off between the socket and the cylinder head :(
