Oil pump replacement tips? Best sealant?

[Greeney887]

currently replacing my oil pump on 4efte after discovering an oil leak coming from this area, has anyone got any tips on successfully sealing the pump and sump back on. I know they are notoriously difficulty to get to seal and the last thing i want is to have to strip the whole cambelt off again if its leaking.

Also is there a particular sealant I should use?

in the past we used gray sealant on engine builds---any of the reputable high quality brands should work
gray because it looks oem and you can usually identify engine leaks easier

on the sump, we tended to put slightly more sealant around the "curved" areas to avoid leaks

on the oil pump, be very careful not to put on excessive amounts and/or get sealant in the wrong places

we used to let it cure for 24 hours

Some oil pumps also don't come with the grooved slot for the o-ring so I'd say just ensure the surfaces are clean and dry enough for the Queen to eat from.. and wet-install the assy after using any high quality (gray) sealant as mentioned.
Don't run the engine until it's fully cured, a day usually suffices.

Thanks for the reply, I’ve read up about causing a blockage in the oil pump if too much sealant is applied, can anyone identify where the sealant should go on the oil pump. It’s groove in block pump, cheers

I've never had any issues with bog standard rtv sealant.

Just make sure you apply it on clean, oil free surface and don't put too much on. Let it cure 24 hours and you should grand

A little tip (which most rtv sealant packaging suggest anyway) is to nip up hand tight, leave for about an hour (this varies based on temperature and humidity) and then final tighten.

Yeah.
"Wet" application helps the sealant get to 'catch' better and give you a good seal.. of course your surfaces need to be spotlessly clean. Brake clean does a swell job of cleaning up..
