oil filters

[PushinTheLimit]

Wix filters here on my stuff... Hendren recommended them and who am I to question their judgement.

i like the wix filter to but i stick with motorcraft 7.3 diesel filter and a fellow named jack cornett turned me onto that several years ago.........

[brad hibbard]

look at that ---a simple question and we have good conversation with some interesting facts
I am gonna be honest and admit ---I didn't realize some filters have bypass valves in them
good information for me
I was just researching something else on the web and took a moment to check in on this thread
I will give it a closer read when I have more time but I am glad to just see conversation

Race-1 uses all Wix for some specific reasons that I will outline later after I make sure they are correct --LOL
I have quickly checked and the Wix racing filters that we use do not have bypass valves
there is good and bad to bypass valves and that is something I will consider in future posts and recommendations.

seen where diffent oils can be as much as 10 hp on a dyno,.has anybody ever tried dyno'in different oil filters??

[brad hibbard]

there use to be a guy on here called dynoman 14 and he had all kinds of space age products one of which was a special oil filter
one of my customers bought one of his "special" filters and brought it to me
it has a completely white can with no markings what so ever but when you look close it had 51061 stamped into the head of it where it screws to the block
51061 is a wix number ---so my guess is ---it was a simple non racing wix filter
I never did test it---it is actually a great conversation piece.

I also had a customer that ran NO filter
he claimed that he saw a power increase on a rented chassis dyno---I never tried this

here is my thought on filters and power---
some filters (due to restriction) will create extra oil temperature
extra oil temperatures will cut power

Interesting about the no-filter part!

I wonder what laboratory could test the "particulates" caught in the filter media for their composition.

Maybe, we don't need one!

Maybe, we don't need one!

Any one that has been around tons of engines for a long time will have ran across this more then once.

On a stock SBC the oil passage from the rear main bearing that goes up to the stock oil pressure sensor/line has a press in plug that blocks the passage to divert oil to the oil filter pad. Many shops don't remove this when hot tanking or cleaning, but many will and if your not used to it when you get it back you have no idea it was removed and people don't put it back in. With it like this it will just bypass the entire oil filter and never filter any oil except some residual oil that may happen to flow thru it (it will fill filter with oil just not flow thru it to actually filter the oil).

That all said, I've seen this happen plenty of times when guys build their own engine and take it to have dyno'ed. Almost every one will eventually lock up on the dyno or kick a rod out of them from completely trashing the main bearings from debris in the oil that isn't filtered out during break in and early stages of the dyno'ing.

So can you run without a filter, guess it possible but I've seen many that won't make it thru simple break in and a few pulls before the bearings are trashed.

I have a 1/4" rod hanging on the wall that is marked at the distance of the top of the block to the plug to check if the plug is in the block, if the rod goes past the mark about 4" there is no plug or if just short or too long from mark the plug wasn't installed correctly. I would check every one when guys used to bring engines for me to dyno, when I was installing the engine on the dyno before I installed the oil pressure sensor.

lol, i remember dynoman, he was funny, till it got ugly! remember the thread bout them filters to! last i remember was a long long time still wating for filter to arrive! lol

Excellent post Mr. billetbirdcage

a 100 years ago we used to knock that plug out of every block before tanking it --but we always reinstalled it for the customer
I actually made a special installer to get it exactly where I wanted it
But there were some blocks that I just wasn't comfortable with the way it went in and was worried about it moving and causing a restriction ---so we quit taking them out at all about 20 years ago --but we final wash that passage very carefully and look down in it for debris with a small flashlight

very easy item to miss---great tech tip for anyone doing their own assembly---Thank You

Its been awhile since I put one together, but it seems to me we used some kind of plate/adapter that covered that up.

Dyno Man was full of more (not a nice word)(not a nice word)(not a nice word)(not a nice word) than a Christmas Turkey he was getting 500+ hp from a 604 with special plugs oil oil filters special air cleaners etc.He was always good for a laugh.

[dirty white boy]

dont forget his special treated valve spring that let a crate motor turn 68, 7000 rpms and last all season!

[ZERO25]

Lets just say he had some interesting ideas.......I do know for a fact that he had a good reputation in the engine machine shop equipment! A family member of mine had many dealings with him.....all good ones!

[ZERO25]

His engine shop is called Alien Race Engines. Its still listed as a Durrance Layne certified engine-rebuilder.

I agree no filter is going to end up in heart break. Maybe at a nascar level shop/assembly room you could get away with no filter but weekly/regional even national late model guys. Stuff just happens and gets in the oil. I would say if you are to try it you should run one for the first dyno session and first race or two then try it without, stuff is wearing in and all the stuff we missed cleaning is being filtered out.

Hey what is the measurement to make sure that plug is installed?
