bigger oil filters

Mac · Post by **Mac** » Mon Jan 16, 2006 12:58 am

well, in my search for the biggest oil filter possible to put on a tercel, i found the fram PH8A, might work, it will thread in perfectly, but the gasket might be a little too big as far as diameter is concerned.

if anyone is interested, its the oil filter that goes on a 82 landcruiser, diesel, gas, same oil filter.

i bought the fram FL8A so i can compare it, and see if the gasket will work, best of all it was super cheap, $4.07! (cdn) and is about 4 times the size of the stock flter which should increase oil capacity to around 5L (estimated)

if this dosn't work then the only other option for the tercel without some sort of adapter/remote mount kit will be the celica GT-S filter (toyota 90915-YZZF2 or fram PH4386)

the 1994 supra filter might also fit (fram P/N PH3614) but again the gasket issue may be a problem. i'll let you know my results as soon as i find out, but don't let that stop you from researching on your own in the meantime.

I just use the filter for a 4a corolla, it is probably 2x as big as the recommended and it seems fine. How big are you going for?

I wonder if the flow capabilities of the stock oil pump would even be able to take advantage of that large of a filter. Being that it is mounted almost completely sideways, and some of those are mounted at an angle or close to vertical. It shouldn't be an issue, but just a thought. Haven't really looked into flow rates of various Toyota oil pumps.

Damn, 4x is huge, will it fit, gasket allowing, without interfering with anything else?

Have you looked at filters for other cars besides Toyota?

I got this info from a maker of remote filter kits. Some Suzuki owners like to use Ford 5.0 filters, they might fit the Toyotas too. I'm not sure if the o-ring diameter applies to all these cars, or is just what the adapter kits use. Check carefully before using the "wrong" filter.

Theads = 3/4"-16

O-ring = 2-1/2"

I use the 5L filter on a 3L engine...it's pretty large. The o-ring fits on a flat surface...so there's some latitude for being off some...but there are issues of bypass valves...where they are located,etc.

well, a large oil filter can't be an issue, i'm just not sure if i trust the backflow valve of the fram filter.

as for the bypass valve, using a bigger filter will only mean the valve will open later rather than sooner, so if your redlining your engine its using filtered oil rather than bypassed oil.

i took a couple pics, but imageshack isn't working right now so i'll have to post them later.

as for interfearance, i don't think the tercel will have an issue, but i can't be certain untill i try it out.

i just wen't to the fram website and looked up the oil filter for the 5.0 mustang and it is the PH8A i have, the ford PN is FL1A, personally i'd rather use the motorcraft filter than fram, i'll take the fram to work tomrrow and compare the two filters, mabey the FL1A's gasket will work better.

well, i was screwing around with my echo since it uses the same filter as the tercel(YZZF2), and i found the PH8A does not fit on an echo, oddly however a ford FL-400S from my brothers 2.3L ford ranger fits perfectly!

the FL-400S is a little over twice the size of the OEM celica GT-S filter (YZZF1) and the GT-S filter is half an inch taller than the tercel/echo filter.

if the PH-8A is too big for the tercel, than the ford FL-400S should be viable alternative for a big filter, provided the seal does not turn out to be an issue.

the fram PH 3600 is the equivelent of the FL-400S

success! the bigass PH8A fit on the tercel without any issues, the gasket is a little bit bigger in diamter than the stock gakset, but its 90% of the gasket area makes contact with the block, so i doubt i'm going to lose oil pressure, and i made it tight as hell for good measure.

i'll try to get pictutes tom of the installed filter.

as for what my new oil capacity is i have no idea because i used an undetermined amount of leftover 5w50 from the echo and 3 litres of 10w30 i got from work which put it right between the two marks on the dipstick.

I don't understand why people knock Fram filters. That's all I have ever used on my Tercel for the past 20 years. The car has 339,000 miles on it...doesn't burn any oil. If the oil filter was inferior I don't think the car would have attained that kind of mileage.

No...I don't work for Fram.

They are smaller and seem to have a higher failure rate.
I prefer stuff like the Purolater Plus. Its twice the size, more pleats, more capacity, finer pleats.
Plus my magnets.

poor backflow valve allows oil to drain out of the filter instead of staying in it, and the filters don't filter very well, if you switched to a toyota OEM filter you'll notice the oil staying cleaner longer.

the only reason your car has that milage is because its a toyota, not because of the filter you use.

pressure rises quicker, and also what you say oil lasts longer cleaner

I was looking at a Fram PH8A the other day...looks like it might fit....has anyone tried another brands equivalent filter?

Seems there is call for another "great work" post...

This PH8A filter fitting the terc is a wonderful thing. This being the case take a look at this site, http://www.trasko-usa.com/ I have used them and really like it. The cost is more. Was about 70 for the case and 10 per filter when I fisrt got mine (for a different applicaiton). Knowing the the PH8A fits this opens up the ability to use a remote and duel filter if you wanted. The neat thing about that Trasko is that it is a by-pass filter. It allows for the use of a REALLY fine filter media while maintaining great oil flow. I have personally seen my oil stay clean for a very long time in my Jeep.

Again great work,
