Ok, just got a quick question, do all 350 use the same oil filter from 87-95? I will be buying a block in that year range and I would just like to know what ACDelco Filter to buy, if they do I would like to get the largest filter I can for the break in and after, maybe the truck oil filters are larger. Any one have any ideas or clues?

 

Yes.

PF-25 is the short one the book lists for these cars; PF-35 longer standard construction; PF-35L synthetic element; PF-1218 I forget what the difference from PF-35 is.

I have been using a two quart oil filter made
by A/c Delco. It is the long type, but don't have the P/N. Nice to have that extra quart of oil in the engine.

 

I 'think' the 1218 has the anti-flow back valve. The PF35 long filter holds about 1 qt. Some companies make a 2 quart filter, but it's really long--truck only.

I think 82 may be right about the 1218, it's either that, or a built-in bypass valve... can't recall for sure though

The 1218 has an anti-drain back valve.

PF932 is the 2 quart filter... Its a bit too long IMO.

 

Funny, I just bought one, and the guy said that I needed PF47. Can someone shed the light on the situation?

The PF47 is because you have a V6.

I use the PF1218 on my V8. It holds more oil than the stock PF25 and it does have the drainback valve. The 1218 isn't too long, it is about 2.5" above the bottom of the oil pan.

Ahh, ok, I see.

Next question, is there any hop-up I can use in terms of oil filters and better filtration? (IE more oil capacity, synthetic element, drain-back valves and ect.)

Did someone say the 1218 was too long?

I think the best filter is the one thats made the best, not the one with the best materials. Fram is a key example of that, good paper, lousy construction. Personally I think synthetic is to take another 5 bucks outa your wallet when you change oil. Anti drain back is probably a good idea. Other than that, pick a good filter and change it regularily.

 

Is a filter with a anti-drain back valve really neccessary on a small block chevy, the filter is positioned so that oil will not drain out of it, or does the valve help keep oil in the passage ways of the engine that lead up from the filter, by the way I read an interesting oilfilter study http://members.nbci.com/minimopar/oilfilterstudy.html
It's a MOPAR site but makes good reading.

Xeno (and other V6 guys), don't use the PF47! Er, okay, well, you can use it if you want, but there's an alternative.

Find the PF-52. That holds twice as much oil as the PF-47 does. In fact, here's the info on those filters! In '82, GM decided that the 2.5l I-4 and 2.8l V6 should use the PF-47. They spec'd this filter for the V6 until 1988, where they decided the 1988 2.8 should use the PF51! As you know, nothing was changed to the 2.8 between 1987 and 1988. GM continued to spec the PF51 for the 90-92 3.1l engines.

The PF51 had no anti-drainback valve. GM stopped making it, and came out with the PF-52. Use that one. (Actually, "good luck" finding a PF51 on the shelves; they're gone.)

You'll need an extra 1/2 quart of oil, though. This boosts your oil change from 4 quarts to 4.5 quarts. I pre-fill the oil filter (which you should do anyway, to any engine, with any oil-filter) with a 1/2 quart of oil.

what do you guys think of the double and extra guard fram filters? better than standard AC?

 

I would not put a Fram oil filter on anything I own. Look at the "minimopar" site link above, where some guy did a real simple oil filter comparo, cut them open and took pictures, measured the amount of filter media, etc.; you wouldn't believe how junky the Fram looks inside.

Stick with the AC or other high-quality brands, which doesn't include Fram.

Ooops, the old link is dead, here'e the new one...

pf-932 from acdelco

here's a pic of it.

it comes about 1/8" above the bottom of the oil pan. now for you guys with the oil cooler, it will be too long. total 6 quarts.
