Thread: 3 litre inlet manifold crack problems

Whats a kit cost?

best of luck, I’m sure it will be fine. I know the feeling though. the feeling of accomplishment when it all works out is worth all effort.

BTW, whats involved with the new injector kit? Is that just new pipes, clamps and o rings? Do you have to re-educate the ecu if you remove the injectors?

Would be interested

New clamping plates (with fresh curvature to force the injector hard into the cylinder hole under tension), new o-ring for the body and the return fitting, a new copper washer on the base of the injector and finally a new pipe fitting.

In regards to the injectors, nothing needs doing other than putting them back into the same position you took them out of.

And she lives again! So far no air, fuel, coolant or oil leaks. Now I’ll change the ARB bushes on the front.

Mine started small but by the time I got to it, it stretched from one inch to three in no time.
My drivers was done 90,000km ago. I was considering doing both again but fingers crossed the replacement is stronger.

Looks like my left hand inlet manifold has a small crack, can't really see it but has oil in the right place. 195K. Unusually looks like LHS has gone first. I have been researching the parts. Do these look right, anything else I would need.

I’ve not used a kit before, instead ordered the parts. I have both the balance pipe and high pressure pump to rail pipe for the LHS at home unused. I’d practically give them away if you really want to use them, but I couldn’t get in there to fit them so reused mine. Yes that’s not advised but I know of many independents who have without issue. I await mine to burn down
