Manually turning td5 engine counter clockwise?

The wildest man in town · Nov 8, 2020

I’m changing my injector seals and might have been a bit too eager. Turned the engine counter clockwise one or two turns. Now when I turn it CW in feels like it’s not moving as easy.
Have I ruined the engine?

l doubt it.
But someone with more knowledge may give better advice.
lf it was me l would just start it and see what happens

Probably on the compression stroke so it will be harder to turn by hand.

If the injectors [ or some of them ] were out when you turned it the wrong way and then were back in when you turned the correct way there would be a difference in the effort needed to turn it. Not done it with a td5 but have turned others the wrong way with no problem.

As tottot says no problem turning the TD5 the wrong way.
My only concerns would be:
1. Did you release the fuel pressure before removing the injectors? if not fuel can (but not always) run from the cylinder head galleries into the cylinders on one or more of the cylinders. This at worst can cause an hydraulic lock and trying to start the engine in this state can cause damage.
2. Did you turn on the ignition whilst the injectors were out (hope not) because this also can cause the above.
So if you released the fuel pressure and did not turn on the ignition you should be good to go.

The OP might be trying to manually turn it with some fuel in a cylinder or two. ie against a lock
It might be worth taking heater plugs out and turning it over. An oil change might be worth it too.
