    Oil Loss Issue

    Something to report, the same day after I had cleaned the MAF sensor the way many videos in YouTube explain explain it, later in the day my service engine soon light came on. The following day it remained on for quite a while and eventually turned off on its own without reshowing since. Looking on the Vyncs app when the code was actually there it mentioned "Evap system leaking (gross leak). It seems to have fixed itself though and I don't know if I should be worried.

    Oil Loss Issue

    Okay that makes me feel a whole lot better. I appreciate all of the info and I might just take it to a mechanic to get a definite diagnostic rather then fiddling around with it myself. I've gotten the maf cleaner and will be doing that soon, I'll then probably hand it off to the professionals for the rest. Would you happen to have any idea how much getting the valve cover gasket replaced or tightened might set me back? Also having them use a smoke machine to try and find a vacuum leak I can't imagine would be that expensive unless I'm wrong. I also noticed that the exhaust is pulsating in the slightest manner, not a constant stream of exhaust which leads me to believe that there might be a misfire but within the computer threshold that will set off a code because my dash shows none.

    Oil Loss Issue

    Looked around my ignition coil locations and I noticed on the drivers side, it seems like all 3 have a oily residue caked around the outside on the surface, not on the coils but on he surface of the body surrounding where the ignition could sit in the engine. Take note I have not tried to remove hen to check the spark plugs yet. I'm wondering if this means theres something entirely wrong? I know I have spilt some oil over the sides of the oil filler hole when refilling occasionally but this only exists above the one ignition coil, I doubt it would have spread to all 3 on that side of the engine.

    I'm guessing there's most likely some sort of vac leak but finding it on my own with the tools I have would be a real task. How is it you would go about cleaning the MAF sensor, I'm guessing it's a process of taking off the intake rubber pipe and looking inside? Also are taking the plugs out something that is possible without having to take apart everything including the plenum and such? Have you done it yourself? Sent from my iPhone using Tapatalk

    Oil Loss Issue

    Yeah i started college last fall so likely it had been sitting for extended periods of time with out being used. Maybe my parents occasionally used it but not very much if any since it sat in the garage. How long is long though, I might just replace the filter anyways since it's fairly cheap and it rules out this as a possibility. Now I actually noticed something interesting today, I tried looking for a vacuum leak and through all the infinite number of hoses, (visually inspecting the engine is pretty much a lost cause for me) it seems like I hear a pretty sizable amount of air escaping somewhere closer to the driver side behind the engine. Now there's no way of telling if it really is a leak or just my imagination created by the fan or engine but to me it seems like it's separate from the rest of the commotion going on. I've always heard a very high pitch ringing since I've had the car but not necessarily coming from the engine though I heard this is a symptom of a vacuum leak. I can't tell where it's coming from due to the nature of a high pitch sound but more likely then not it sounds like it would be some tiny air leak coming from some part of the exhaust manifold. I've looked under my car and it's a rusty piece, all along, but just giving it a quick once over I can't find any particularly noticeable leaks. As for the spark plugs, I definitely should get them looked at but I just don't want to spend the money on getting them fixed and then proceeding to burn oil, ruining them at a much quicker rate than they should normal ware.

    Oil Loss Issue

    This is starting to make a little more sense. I'm starting to think my spark plugs are at the end of their lifetime. With the addition of a known oil loss issue more likely burning, its a no brainer to get them checked out. I actually replaced my fuel filter around a year ago and I believe it should still be in okay shape. Is there a chance it could have gone bad though before it's expected lifetime? The metal clamp I mounted it back into is all bent up from a frozen rusty nut that took forever to remove, but something like that wouldn't cause it to fail I hope. I also had one of my 02 sensors replaced around half a year ago after it failed but I can't remember exactly which bank it was. Now going back to what you said about the valve cover, how come the 2nd mechanic wanted to re torqued it after having already gotten the gasket replaced? Do the valve covers cause burning or leaking when not tightened correctly? Also what is the cost for something along those lines, possibly also replacing the pcv valve while they're at it because it's a common fail point and it's so close to the valve cover? Finally, the error codes are not actual codes thrown by the vehicle. I have a Vyncs reader that stays in my OBD 2 port all the time giving me information about my car via app. Occasionally it'll send me a notification of low fuel economy or engine fuel system lean but the parameters of this device could be so close to the normal range that these are basically within the normal limits of the car. There are a plethora of possibilities though as to why my car would be running lean, but could it be due to fuel filter having gone bad? I know having a system running fuel lean definitely has an impact on performance. Sorry for asking so many questions in no particular order that makes sense by the way, I'm just kind of saying everything that comes to mind first. Sent from my iPhone using Tapatalk
  8. I've had my 02 patty for about 2 years and ever since I can remember it's had some oil loss problems but more recently has it been getting unbearable. I'm the 2nd owner and I believe the first might have sold the truck knowing it was going to get worse. Regardless, I'm having to fill half a quart around every 2 weeks at the least. I've switched to synthetic fairly recently, around 5 months ago, its not until more recently has this problem become bad. Checking for leaks there is nothing I can see, especially for the amount that is lost. I'm stumped though because I have not seen any soot or black smoke coming out of the exhaust, or even smoke for that matter. I've even had other people look at it while I drive. This is completely separate from my decline in acceleration problems which I believe is somehow linked but not totally sure. So after scowering the internet I've come across the possibility of the reason being because of a failing PCV valve or valve cover. I've heard of there being an updated system put out by Nissan that essentially fixes the common oil burning issue from pathfinders but I have no idea where to find this or even explain to a mechanic this idea without sounding crazy. I'm also wondering if I should get my spark plugs and ignition coils looked at as well when I finally do get the truck into a shop for the oil because I believe they are greatly affected by the constant burning of oil. In another regard I'd like to fix the source of the oil issue first so that I am not showing up in the shop for the same plugs over and over again. I'm basically lost as to where to start and maybe get an idea in how much this fix might cost. I really love this truck and would do a lot to keep it in its happier years for a little longer but if it's too astronomical it might not be worth. Also forgot mention that I have a Vyncs Reader in my OBD2 scanner port for many purposes and I keep getting the error notification of poor fuel economy and another error saying engine fuel lean but it seems to only appear occasionally. Don't know if this helps but I thought it might be helpful to mention anyways.

    What is the point of installing Warn hubs? Also do the front ball joints and steering racks tend to go bad, is that why you recommended I check?

    It's more probable that I'll wait until I get all the parts to install because it's more practical. It's just going to take a minute that's for sure. I'm wondering what the backspacing is because I would like to also put some 1.25" spacers.

    Ive been looking around for some information on this subject but can't seem to find exactly what I'm looking for. My question is, can I install 1.75" lift OME coil springs on the front and rear while keeping OEM shocks and struts? I'm the second owner of this vehicle and I'm sure the shocks and struts have not been replaced in a long time if they're not originals. I can tell now I should replace them but will get to that when I have the money. If this does work will it cause any problems down the road when I finally decide to replace the shocks with OME and struts with KYB GR2s? Also with that setup what would be a smart tire size or specific tire without needing to trim or very little trimming. I was thinking 31x10. I have the very good looking 17" wheels off a 2002 pathy if anyone knows which ones I'm talking about.

    I actually have a 3.5 if that makes any difference.

    R50 acceleration problems

    I definitely agree with what you said Citron about throwing parts at the car. It's pointless unless the problem is actually known. In other news I got my truck back and they replaced the O2 sensor, serpent belt, and fixed an oil leak. Also gave it a new inspection sticky all for $500. I'll be broke for a while like I said haha. Anyways the truck seems to perform a little better in the higher end acceleration. It picks up more than it used to but lower end still seems to lag and the lower gear shifts seem a little slow. I did notice that after getting it back it seems to idle higher. It's around about 900 rpm now rather than being at 750 to 850 vs before I got it fixed. In regard to the PCV valve I think I want to do that as my last fix before I stop spending money because I've already dropped a lot. It's only $10 and I at least want to check that it is functioning. My question though is I'm unsure where it is located. I've looked around on the internet but I cannot get a straight answer. Is it a simple find or will it take some unbolting of other parts? And if so how much?

    R50 acceleration problems

    As of this point my guess is that the downstream O2 sensor has failed because the catalytic converter is not doing its job. Now the catalytic converter had to have failed for another reason which is what worries me because I pretty much know my engine consumes oil. I am looking to get the PCV valve changed to see if that is the culprit but if not.....does that mean I'll have to change the catalytic converter ever so often just because the engine burns oil? Also could leaving the PCV valve in place well after it has already seen its last leg cause internal engine problems, or only the engine to lose oil and send it into the cats to clog it up?

    I see, hopefully things start to piece together and make sense at some point in the near future. Dropped my car off at a shop today to get the sensor looked at so I will report back the findings when I obtain that knowldege. I hope this faulty sensor doesn't mean my cat is failing! If so I'll be broke for a while. Realized the whole underside of my engine is covered in a thin layer of oil the other day so that's nice. Can't wait to get past this stage of fixing up and on to better things for the pathy!
