Rough idle 1.6td

[Wltrc]

Got the new injector nozzles in and tested, 155 bar plus or minus. Still idles like crap so I guess it wasn't an injector issue. However now I've got an injector body that's leaking where it goes together, torqued them to 52 foot pounds as per the manual. Any chance it will seal up on its own? Or is that just wishful thinking haha

I'd say wishful thinking.  New injectors shouldn't leak, however.

I would take the delivery valves apart and see if the internals move freely. Ive ran into a few "seized" valves that began working with mild persuasion

I'm late to the party here. Its been a couple months now, has the issue resolved?

I went through the exact same scenario you have to this point. I replaced nozzles and they started leaking because they need to be shimmed properly to "fit" the new nozzles to the injector body. I ended up replacing them with reman injectors.  Still didn't fix my poor idle problem.

I had a spare fuel pump that needed the seal for the distribution block changed, (not a novice repair). I got the seal kit, replaced the fuel pump and now it idles like a dream. Might be time for a fuel pump.

Mild persuasion is popping it with something less that a 16 oz hammer I believe.

Nope never got it figured out. Been driving it as is, it runs very well other than the strange idle.

Going to save up for a while and send the pump out to Giles for a rebuild eventually.

 You can pull the injectors apart and lap the surfaces to get the injectors to quit leaking at the halfs.
