Is the small screen mesh removable for cleaning? What is the best way to clean this?  |

In all honesty, I replied earlier, but deleted my post. I`ll probably regret this, but here goes !!
DO NOT USE COMPRESSED AIR ON THIS "screen"
This is a pressure relief VALVE. NOT a "screen" If you dislodge the valve. or weaken the spring with compressed air, you may HAVE to remove the assembly to assemble it properly. An unseated valve means unfiltered oil. The stake marks you see around the seat need to be worked out to remove the seat, valve, and spring, then re staked upon re-assembly. Just soak in fuel oil, don`t use crazy harsh cleaners.
And if you do dislodge the valve, or damage it, or weaken the spring using compressed air, you`ll never know, you`ll just be by-passing oil !!!! No idiot light on the dash for that !!

Thanks Dave. When you say fuel oil, do you mean kerosene or diesel?

Either, just different weight is all.
Do what ever you want to the outside of the adapter. Then submerge the adapter in clean fuel, take it out and shake it around to slosh the fuel in the passages. Tilt the adapter in several different positions to drain the dirty fuel, and repeat till clean. If you look in the center port (the threaded port on the head) from the adapter side where it bolts to the block, you`ll see where the by-pass is ported just behind the oil supply port to the engine.
Don`t be tempted to remove the valve and drop a dime in it`s place thinking you`ll get better filtration. You can eliminate the valve, but only if you go to a by-pass filter (and that`s really a bad idea) Stick with the by-pass valve in the head, and a full flow like designed

So dave if thats clogged up would that cause oil to bypass the filters rubber seal?? If not what would cause oil to bypass a brand new filters seal? I just had this issue today.

So what your saying is you have an external oil leak that your sure is coming from the filter seal ring, and for sure not the adapter to block gasket?
These by-pass valves act much like by-pass filters (only cleaner) Oil is by-passed much more often than you`d think. Cold start, quick acceleration, heavy oil to name a few. I've never seen, or heard of one of this style by-pass valve fail to OPEN, I`ve seen them tipped in the bore which would cause them to be always OPEN. (this is usually the result of wiping down the adapter with a rag when changing the filter and tipping the valve)
I`m wondering if the leak is in fact coming from the filter seal, could it be filter over tightened, too loose, damaged sealing surface on the adapter, bad filter?
I`d clean it all up, make SURE it`s coming from the filter, replace the filter.
To answer your question ?? It`s not an easy reply, but yes, IF the by-pass valve were plugged, or disabled,oil COULD be forced to leak pass the seal. It`s normal for several reasons for this valve to open as stated above. If the valve was plugged and the oil for any reason could not pass thru the filters media, since the filter is a full flow, it would probably leak

Filter was on for 800 miles then it started leaking, put on new filter and same thing instantly, oil pressue guage is also reading a bit higher than normal. Will get my head in their tonight.

good filter, good number
When you remove your filter look up at the valve, see that it`s where it belongs. Take your pinky finger press up gently make sure it moves upwards with little effort. It`s only a 10 to 15 psi variance relief, so very little effort is needed to unseat it

Here are my thoughts on this topic. Take it with a grain of salt, it`s worth about a penny. I`m not a computer guru, or any sort of guru, so this will be kinda crude I`ve never run in to this problem on any olds gas engine. Although it was a common problem on the 350 olds diesel. Without getting in to the common "cure" for the diesel spitting out the filter sealing ring, lets first look at the stock filter adapter.  basic oil flow, lower right hole, oil under pressure from oil pump to outer ring of filter. from there the oil is filtered thru the media, enters the center of the filter and travels thru the center threaded pipe to lubricate your engine. If the flow is too great from the oil pump, or oil is too thick, or filter media is too dirty to handle the flow, the pressure relief valve will open and the oil will be re- directed UNFILTERED to lubricate the engine. SEE PIC BELOW  So to sum it up. Oil from the oil pump enters the filter thru the hole to the right, returns to the engine thru the center hole(the threaded nipple) If the oil can not pass thru the filter media fast enough it then unseats the pressure relief valve, bottom hole, that ties in with the center hole to return to the engine for lubrication.  Now all of this makes sense to my pea brain, but I tend to ramble. Here`s the pressure relief valve. IT IS NOT A SCREEN, it is of a solid material, it sits on a seat, with a spring to keep it seated. In an earlier post I stated it was approx 10 to 15 lbs. variance, I was wrong, diesel is 10 to 15, gas is 8 to 10 psi. (diesel is prone to pissin out the sealing ring) You`ll notice the dime (10cents) in the pic. a dime will (and has) replaced the seat of the pressure relief valve. DON`T DO IT !!!!! The valve is thicker than a nickle (5 cents) From left to right SEAT VALVE SPRING Dime as referance  Gasket, Make sure your gasket is metal reinforced. That`s a magnet suspending the gasket Victor reinz  |
