So i just want an opinion as my car is still leaking oil from the oil filter. my brother asked around to a couple shops an they said it could be the head gasket getting ready to go out and its building up pressure an goin out the oil filter. i drive an 02 cavy wit the 2.2OHV motor
Usually when a head gasket goes, it creates pressure in the Coolant system. are you sure the oil filter it good? did u oil the seal before installation? i'd changed the oil filter first.
i have replaced three oil filters and the same thing happens less then a week after installation. i oiled the seal of each one before they were installed. two microguard and a wix that is on there now. the mating surface was wiped off with a shop towel each time as well and it cant be stripped or it wouldnt go on as easily as it does. this problem is ridiculous if you ask me
if it had an oil change recently, pull off the filter. I have seen the old gasket get stuck. A double gasket situation could cause this..
well ill check it out but if i remember correctly the gasket came off on each of them that was pulled. i could be wrong though as microguard filters do blow @$$
newt time you take the filter off, look at the oil pressure switch. i'd almost guarantee that's the issue. if it cracks, it will leak, directly onto the oil filter.

the last time i watched it leak out the bottom of the oil filter while the car was running because i dont have the splash shield on the right side and had a clear view of the filter. it didnt flow out but it was an intermittent flow. kind of like a burp. the oil filter is clean as well so i know its not leaking onto the filter
You've posted on this problem twice now. I'm not complaining, but now you've gone to the trouble of asking around, etc., so lets get to the bottom of this.
1. What you describe sounds EXACTLY like what happens when you take off an old filter, leave behind the gasket, and put a new one on. I've done it myself, no problem.
2. Your post above shows that despite being advised to check this, and I mean check it, you didn't. Also fine.
3. The problem arises because you aren't going in the order you should. You have recognized a problem, "oil leak at filter". You have been told what to do first, check for the common, always happens, easy to do and cheap to fix situation, old gasket left behind. And from your above post its clear you haven't done this free, fast, and easy diagnosis. Instead, you have your brother talking to mechanics about situations I admit, I have never seen or heard of before, or comprehend.
4. Your next post should be "I took off the old filter, and poked, prodded, pulled at, and felt/tasted that mating surface, and there is no gasket left behind". When you post that, the other people on this forum will know for sure that the thing this looks most likely to be is not, in fact the problem. Instead, some rare and unique thing is happening. For whatever reason, j-body.org is probably populated with the most helpful and knowledgeable car people on the net. When you let them know, for sure, its not the gasket being left behind, they will help you figure out the problem.
I guess my point is, apply the basic techniques of problem diagnosis. Start with the common and probable, and only once you have eliminated that do you start moving to the "I heard one time a guy in Sri Lanka encountered ________" diagnosis. I'm sorry if I sound like a jerk, but I am, and so thats how I sound. Make damn sure there is no old gasket left behind before you start tearing your engine apart.
I took off the filter and theres no gasket on the mating surface, theres no rocks on the gasket, theres no rocks on the mating surface, the mating surface is completely fine, the filter is fine as well. dont say your sorry for sounding like a jerk because thats the only way to get through to people. and i didnt even tell my brother to ask around he just called me one day an told me he asked around an thats what mechanics were saying. i didnt really understand it either.
oh and the first time i posted i never saw any replies before i put this post up so my bad on that one
and could it maybe be the oil pressure relief valve
I would say yes, the next most likely thing that you should check is the oil pressure relief valve, and more imprtantly the spring in that valve. It should be located on or near the oil pump. I have never worked on a 2.2, so I can't say for sure.
well i guess my next question would be would that cause the oil to leak out of the oil filter
Sure, it would cause oil pressure to be too high (assuming it is stuck) and therefore "force" oil out of the weaker points in the system, one of those being the filter gasket.
ok. well i looked in my haynes manual and it says nothing about the oil pressure relief valve at all. the only thing it talks about is the oil pressure sending unit. do u know where it would be located or know someone who would know. i have a blown motor in my garage i can find it on before i go on to the motor in the car so i dont mess anything up
is the oil pressure relief valve and oil pressure sending unit the same
No, the pressure sending unit just measures the oil pressure and relays that to the ECU. I have never worked on a 2.2, but the oil pressure relief valve is almost always integrated into the oil pump. It is just a ball bearing with a spring behind it. You will have to remove the oil pump to get to it, and again, not having worked on these I don't know how much hassle that would be. Depending on why the motor you have blew, you may just want to swap out the one oil pump for the other.
the old motor blew a head gasket but badly. the oil pump should be just fine
