Oil filter housing

Alright tundra crew I have a question that hasn't been answered here and it's not what size tires I can fit on stock rims . So yesterday I changed my own oil in my 17 tundra 5.7 and I was checking out my oil filter housing and it looks like the previous owner had either overtightened the filter cap and had to chisel it off, or some quick lube tech scratched the hell out of the bottom of the oil filter housing on the engine block. To be absolutely clear here, it is a decent chunk of metal taken off of the metal housing not the plastic cap that holds the filter in it. I know I should've taken a pic but I'm not draining 8 qts of oil I just put in fresh for a pic it will have to come later. It has not shown any signs of leaking at all before I took it off and hasn't yet leaked out. My question finally is, how hard is it to change said housing if it does turn into a problem? It's stuffed in the block and has steering and coolant lines all over it so it looks like a heck of a job. Saw on YouTube someone stuffing the 5.7 in a Tacoma, he had the motor pulled and on the taco frame and it looked very full of things in the way. Is this something I should look into fixing or since it's not leaking just saw screw it and turn up the radio

 

Can you post some pics?

Sounds like it might be ok as long as the area where the big o-ring mates with the housing is still intact. And of course you still need enough threads to hold the cap in place.
(Most people upgrade to the venza metal cap BTW)

 

The filter adapter?

Without seeing the damage, there's no way anyone can say. But, turning up the radio doesn't turn out well with an oil leak.

 

I've seen the metal cap, I have no leak as of now. The scrape is where the o ring would make contact with the filter housing between the cap. Its on a flat surface and you can see it without completely removing the oil filter cap.

 

As I said it's not leaking currently, and yes the sparks referenced part is exactly what I was talking about. I don't drive to far or often so it will probably be at least 6 months before I change the oil again.

 

The large o-ring of the filter cap seals on the BORE of the filter adapter, and not on the flat. The flat is where the filter cap, metal or plastic, bottoms out. It is a common misconception that the o-ring seals on the flat (face seal), and probably the reason oil-change monkeys tighten the filter cap bazillions with an impact wrench.

Tundra oil changers also often misposition the o-ring on the filter cap thinking that the o-ring seals on the flat. This typically leads to an immediate leak, so keep an eye on yours until your next change. The beauty of using Toyota filters is that they have a diagram right on the box showing right and wrong ways to install the o-ring on the filter cap.

Without seeing the scratch, I cautiously say if the scratch is limited to the flat, and not down the bore, you won't need to change the filter adapter. A leak past the filter cap o-ring due to a scratch on the bore will be slow drip, allowing you time to find the problem and fix it by replacing the adapter.

 

Here is a handy diagram I keep for those that need to understand how the oil filter cap seals. In all my discussion above, oil filter adapter = oil filter bracket (Toyota) = oil filter housing (Toyota):

 

Wow that is great advise, I appreciate it. It is not in the bore of the cap it is the flat surface that I had thought sealed the cap. Your information has eased my fears immensely thank you
