Oil Filter relocation kit design questions on a BK SOHC EJ22

[outbacktweaked95]

Alright im looking to do a oil filter relocation kit on my car because im looking at making a skidplate for the bottom of the car so that sticks rocks or whatever wont get into my engine when i go off roading. So i was ordering from summit, i ordered the oil plate for the new filter to go into http://store.summitracing.com/partdetai ... toview=sku (http://store.summitracing.com/partdetail.asp?autofilter=1&part=TRD%2D1028&N=700+115&autoview=sku). Once i got it my dad and i got to chatting :smt014 about the ideas of it and he said he didnt think it would work but he would check with one of his friends at work that is a Mechanical/Electrical engineer and has also been drag racing for 25 years. He did and the guy said it wouldnt work becasue the motor wouldn't send the oil to the filter and the oil would just stay in the motor supposedly becasue of the size of the hoses and the pressure. He said that they do them on V8's and they work because he has a electric pump on the return line pumping the oil back into the engine. Being in school for mechanical engineering this sounded a bit fishy to me especially since i would be using 1/2" high pressure hoses to keep the flow as high as possible. So, I asked a fellow engineer at my work who is working on his graduate degreen in vehicle exaust emissions so he is big into engines and the design of them. He said as long as i didnt move the new fiter above where the stock oil fiter was located then id be good because then the oil fiter is above where the old oil fiter was it could possiblly get air into the top of the filter and cause foaming which would take some of the volume of the oil filter and for a little bit would suck air into the oiling system. Also he said that there is no way for the engine to not send oil into the filter unless insanely small lines were used. So the score is 1-1 for and againist it. Id kinda like to get this right becasue if not and the one guy my dad talked to is right my motor will heat the oil until i lock it up on day.
I decided well ask more people maybe they know, so here is the idea. Its a normal oil fiter relocation kit like you would find for a V8 on jegs.com or summitracing.com it consists of a new oil filter base like i have already ordered and a blockoff plate custom made at the machine shop that i work at out of of aluminum for the motor where the old oil filter was on the engine and have 2 holes where the hoses are screwed into. Im going to be going with 1/2" high pressure hoses. the block off plate will also have 2 holes on the side tapped and such for 1/8 oil pressure and oil temperature sensors. The new oil fiter mount will be located in the outer fender behind the stock fog lights so that it cools the oil as well. it will also be located lower than the top of the stock filter and im thinking sidways to insure that the lines have oil in them upon startup, ill also be using a Mobile-1 filter, Purelator PureOne filter, or probally Wix because of the research from http://www.knizefamily.net/minimopar/oi ... index.html (http://www.knizefamily.net/minimopar/oilfilters/index.html) and http://www.calsci.com/motorcycleinfo/Fi ... OilFilters (http://www.calsci.com/motorcycleinfo/Filters.html#OilFilters)

Any responses on this would be very helpful. I searched NASIOC and here and not much info on them besides the pre-made kits look pretty muck like im doing.

You don't need to relocate the oil fiilter in order to clear a skidplate though...

[decke48]

the only way you get air stuck in oil filters is if you mount them straight up. you need to keep them in the range of the highest and lowest spots of the engine that oil flows through. the lower the better. the oil pump pressurizes the fluid and then flows threw the oil filter. so as long as you lines arent to long it wont add to much more work for the pump. though you might loose some pressure as long as you dont drop below 13psi at idle 40psi at 5000rpm youll be fine

I know the filter will clear a skid plate i just dont want to have to take it off everytime i want to change the oil in the car im planning on a solid sheet no holes to catch things. I tore up the bottom of a old subie with a stump i didnt see it dented the pan and all but didnt break anything and i was pretty lucky. Im planning on using 24 inchs worth of hose is that too long im pretty sure it sholdnt hurt it. Gates has a calculator http://www.gates.com/industrial/pressur ... on_id=3044 (http://www.gates.com/industrial/pressure/fluidFlow.cfm?location_id=3044) and with a oil pump that flows 12.4 gpm and streight fittings itll drop 9.4 psi per ft when oil is 130F. This means that i should be dropping 18.8 psi for 2 ft and 28.2psi for 3 ft. I think i can make it in 2 ft for less of a drop in psi. Also should i mount my pressure sensor on the new oil filter instead of beside the block. This should give me the pressure after the drop of the hoses right? Thanks again i really appreciate the help.

you should mount it where the oil light switch is because that moniters right after the filter.. but if you adapter is going to have 1/8 fittings mount it to that but make sure its on the return side. so you going to try to make it 2ft of hose. so 1ft hose on each side. i dont think you should have a problem. but if so you could allways make a quick acess cover for the filter and drain plug. or shim the oil pump to make up the differance

[outbacktweaked95]

actually i recalculated it and i was a bit iffy before about the pressure drop but if i do 3/4" hoses im only looking at 0.22 psi drop so thats what im going to do yea its probally a bit overkill but i still have to make sure that moving up that big wont mess with the flow or anything. I wouldnt think that it would but better to be sure than sry. Thanks agian for the help.

just remember you need more oil. on oil changes. some oil cooler/relocated can use 1-2 more qts

[outbacktweaked95]

K thanks ive got 6 qts but i can always get more if needed when i do it later next week.

I would not do it. The possibility for leaks/fire and the potential loss in oil pressure don't seem worth it to me. additionally, you'll have to drain the oil, so the plate is going to need to come off or have access holes in it anyway.
