Are you doing the top cap seals, upper and lower caps? They can be done with the pump on the engine if you haven't gone to far dismantling the pump. The injector head can also be done in situ. These three are the most popular seal fail issues...

As long as the tool stays in place you can take the pump in and out with no issues. You'll have to time it up afterwards anyway.

Incidentally, that was wierd. Just as I though has someone replied my phone notified me of your response.

The pumps leaking so it's a removal for new seals. As long as its locked off and I don't turn the pump shaft/woodruff key, does it matter what position it's in? As long as nothings changed while it's out it shouldn't affect the timing when I put...

Do you know if the woodruff key should be TDC on the pump?

Wammers did some detailed responses on this. I can't remember who he was helping. There is indeed another hole just before the TDC one. You don't want to be 180° out either.

Cheers. Had a look but it doesn't say.

There are 2 holes in the flywheel. Check RAVE for the full info on fitting the FIP.

Apologies if this is well discussed. I looked but couldn't find a thread. I've got the front cam lobe pointing to the injector side with the edge parallel to the guide visible in the oil filler hole & the locating flywheelpin is in & located...
