mitchell89 Posted May 14, 2023 Report Share Posted May 14, 2023 Best way to prime oil pump Quote Link to comment Share on other sites More sharing options...
BKB94 Posted May 14, 2023 Report Share Posted May 14, 2023 Pack it with a grease that dissolves in oil, change oil filter after initial start. Or remove spark plugs and hook a charger up and spin that motor quick. With no plugs you have minimal pressure on the bearings and it should prime quick.

techboy Posted May 14, 2023 Report Share Posted May 14, 2023 (edited) If the motor is in the car with the pump already installed there is a small allen head plug on the top left side of the engine block just below the head. That oil journal leads to the oil pump. You can thread a ntp fitting in there and pour oil in very slowly b/c it's a small passage and you don't want a mess and prime the pump that way. BKB94s way is better. This is the "opps I forgot to prime my pump method". Edited May 15, 2023 by techboy Quote Link to comment Share on other sites More sharing options...
psu_Crash Posted May 15, 2023 Report Share Posted May 15, 2023 I do like techboy. Only I built a small pressure prime system to do the job. I have never tried the pack the pump method. Quote Link to comment Share on other sites More sharing options...
psu_Crash Posted May 16, 2023 Report Share Posted May 16, 2023 These are awful pricey, but you can get the idea. I built one out of parts they were throwing away at work. Connect it to the port on the side of the engine and apply a little pressure. Once oil is flowing out of the rockers you're good. https://www.summitracing.com/search/part-type/engine-prelubers Quote Link to comment Share on other sites More sharing options...
