Thread: Prefill Oil filters?

outlet side. SBC's have 2 places, one at the top and one by the filter. At the top is the truer reading.

Now I have a new question. Is the oil sending unit generally on the inlet or outlet side of the filter?

Ever since basic autoshop in High school, I have always put a little oil in there(about half full so it doesn't drip out when you tilt it to put it on!) Our shop teacher, Mr. Spellenburg, would always say, lube the rubber gasget with some fresh oil, and then pour some in there on the threads!. It helps getting them off a heck of a lot easier!

when i was at the boat yard they had a run of oil filters that were put on dry and very tight you would crush the can and still not get them to move the next was drive a big screw drive thru the oil filter that would rip the tin can off and not get the filter off and have oil mess in the bilge some of the engines if filter were on the block could be a real deal as you could not get close to the filter to get at it .i had one that got me so mad i thru my oil filter wrench in the river . as all it did was slip i would wear out the band typ filter wrench on some of them boat filters some would come off but the last one had two sbc and had to move one engine over to get the other one out. as the hole in the deck was in the middle of the deck and only the size for one sbc this was covered by warranty to pull the engine to get the oil filters off i allways fill the filter and alway oil the o ring . but first check there is no old O ring stuck on the block still . even if there one on the old filter

I have done some dry sump systems on my race cars that filtered the oil on the way out of the engine to the tank and ran unfiltered back to the engine oil circuits---Clean oil into the tank, clean oil into engine, filtered il to tank, kept tank clean---no pressure drop thru filters, no bypass of unfiltered oil---

Hmmm interesting... It certainly makes sense to pre-fill if possible. One is in upright where the other is horizontal. Both of these vehicles cost less than a good set of heads though.

The oil supplied to the pump makes its way through a full-flow oil filter into a 1/2 inch main gallery on a small block. The main gallery is positioned above the camshaft. The lube travels from there through a hole to the groove situated nearby the rear side of the rear cam bearing. This is the position where the lifters and rear main are oiled. The four front cam bearings have grooves that pass to each individual main bearing. Oil passes down into the crankshafts main journals through tiny holes in the upper main bearings. From the main journals it travels to the rod journals.

yeah fill as much as mounting angle will alow and a smear on the gasket too. the theory makes sense but if its actually useful? i dont know.
I was also told by some random bloke passing by told me if you open a radiator cap when the engines warm-new style with the recovery bottle cap not on the actual radiator- with the motor running that it will depresurise and not flow over with the pressure. i tried this method and guess what-didnt work!
