i have made a few suggestions, but am kinda out of ideas, so input is useful on the following problem:
Oil pressure isnt the problem, its more to do with how long it takes to register.
Long story realy, but as of today its like this:-
Car was drysumped, its now got an SBD shallow sump. After standing for a few days the engine cranks for an age without registering a pressure. What I have found is that if I take thye plug out of the filter housing (opposite end to the relief valve, and turn the engine over a few times then oil gushes from the housing. If I then replace the plug then the pressure registers straight away.
I am guiessing I have an air lock or similar and wondered it if might be something to do with the filter.
Once the pressure is there it runs fine, 4 bar at tickover and everything is rosey.
I have the relef valve apart during the build and it was a free as it could be, pust pulled it out with my finger.
Cars nearly ready to roll now and this pressure time lag issue is stopping me from finishing
seems normal to me. if you imagine and understand that the oil has to rise up a foot of pipe before hitting the engine, it doesnt seem out of the ordinary for it to take a while to build pressure. especially from dry.
i dont get any pressure form cranking alone, it only shoots up when the engine starts.
hmm, just been reading his past threads and i thought he was cranking and getting nothing then it was taking ages to register on gauge. he was para about munching his engine so has now been 'priming' the oil pressure with little success
sent him a quick message to ask if pressure comes up once engine fires as i agree thats not much of a problem really
its if its idling and the pressure creeps up as i first read it tho
