HEy guys, I liek to change my own oil and I have noticed that the filter looks a little on the wimpy side for a v8. Now my L98 had a short filter as well, but there was a filter that was twice as long for it also.

Is there a bigger filter I can put on my LT1 ??
And if so how do I go about looking it up ?
For example I go into Discount Auto to get a purolator filter nad look up the # and it shows the short one. What engine(or car) would I look up to find the part # for teh double sized oil filteR?

I cant stand trying to use a littel filter on a 383 stroker.

 

i use the purolator pureone filter that is twice as deep as the wimpy stock one.the part # is pl34631.i think it is used on 90's trucks.works great and now the car holds 5.75 quarts with a change.

 

A good old ACDelco PF35 is the best bang for the buck filter there is. In all honesty the "small" stock filter has more than enough filter area to clean your oil at even more lengthy oil change intervals. Added oil capacity is a good thing though. If you have a stock, sandwiched, oil cooler on your car the extra capacity oil filter will sit quite low... although the factory cooler is a real hunk o junk anyway and I would probably remove it.

 

I use the K&N HP3002 on my car, it holds about 3/4 of a quart of oil. It still boggles my mind how GM went to such a tiny filter on the LS1s, those PF44s are as small as the filter that goes on my wife's 1.6L Civic! So even the stock LT1 PF25 filter is pretty big in comparison to the PF44.

 

Found another good choice, the Wix 51060. The NAPA Gold is also the same filter (but more expensive) and has a similar numbering system (if you went into NAPA and asked for an 060 they'd know which one you mean)

 

Maybe what you want, is the 8 1/2" lg. purolators that I've got.

 

Wix is a top notch filter, the PF35 is the large filter, this info is in the FBody FAQ which can be found on FBody.org and several mirrored sites.

 

That's the one I use too. It also has an anti drainback valve.

Does that one have an anti drainback valve? If it does could you post a number for me please? I have the number without it.
Thanks

 

Ditto about the Wix. I have a CarQuest filter which is a Wix, and don't get anymore valvetrain noise at startup on a cold day. The Bosch Premium is also a good one for the price.

I believe this one does NOT. It is an AC PF-932 equivalent.

 

Its the Amsoil filter (if youre interested in that) the part # with the 25 in it, the stock size is 24, its quite a bit bigger. Not sure of the letter in front of the 25 though, maybe P.

 

Thanks. I've been trying to figure out if I want to run a short filter and cooler or the one you listed (which is about the same length either way).
