Leaking SBC oil filters

I'm on my second one that leaks.Can you tighten them too much? I've had so many stupid problems with this car!

 

the only time I had one leak was when the rubber gasket from the old filter stuck to the block when I removed it and I didn't notice.

 

I had a particular 350 that would always loosen up oil filters if i didnt really crank them on there. lube the gasket.

 

Yeah make sure the old gasket isn't stuck in there and always take your finger and dip it in the old oil and apply it to the new gasket. Really no need to chow down on these.
One full turn after snug should be enough.

 

Old gasket is off.Surface cleaned.Tightened by hand-leak,tightened with wrench-leak.I put oil on the gasket.I don't get it!

 

Maybe you need to make sure you got the right filter. It happens. Plus.... what brand is it? get the brand and Google to see if it has a history. Lubing the new filter and NOT over tightening should yield good results.

 

This is coming from a Ford guy soooo. Do sbc's have a filter adapter that is held on with two bolts up in the sealing area? could that be loose?

 

SBC cannister-type (old style) did have a plate, held on by 2 1/4" bolts. We always removed that, to get the old gasket out. I don't recall if the spin-on adapters are held on , using that same type hardware.

Blocks before '68 need an adaptor to use a spin on filter. Good suggestion to check this.

 

Ended up being the threaded plug above the filter leaking.It had been loosened for some reason.

 

Cool. Thanks for the update and solution to the problem.

 

it came loose with the filter I use to work in gm dealer back in the 70s and the early chev350 would do this and if it is a 327 or 283 converted to spin this was common tom

 

Most of those aftermarket adapters that converted the can type filter to a spin-on used a Ford or Dodge oil filter. Using a Chevy filter on one will leak like Niagara falls.

 

ive used a lot of them and ive always run ac pf 25 which is chevy car filter... do different brands use different filters?not being a smartass i just want to know...

 

Only several things can cause that. Wrong filter, bad machined surface where the rubber seal touches, or too loose. Lots of theories on the best way to put on a filter, but I clean the metal surface, wipe some oil on the seal (after putting some oil in the filter too) and then I hand tighten it and take it a quarter to a half turn more with the wrench.

Oh, and stay away from Fram filters.
