^huh?

 

i honestly got a headache while reading this.

 

Ill try to help you,

My translation:

Okay, lets take it down a notch. How many miles are on your 350z? When was the last time you changed your oil? Did you do regular maintainence like suggested in the owners manual? (I dont think so)

Did you notice anything strange when/if you changed your oil? You said you pulled out the spark plugs and saw oil, did you change the gasket/s? If so, please don't tell me you re-used the old plugs.

Hold off on changing the oil pump, oil pressure sending unit, possibly tearing you engine apart to get your valves replaced/ re-surfaced*fixed. Test out the minor details first. If you don't have an idea of what your doing have a certified mechanic look over your car.

You will need the ecu from the rev-up. Use the search feature for the rev-up swap. My friend I really hope you get this problem solved, because if you don't you might need a new motor if you continue to drive it. I can't help you with the rev-up part, but you shouldve just gotten another 03 engine and save yourself the headache.

Just my

 

sorry about the gramma i was writting on some real stupid ish.. But i changed my spark plugs and i notice that oil was all in cylinder 5, 3 and 6 the others 421 was cool . yes spark plugs was replaced to iridium i remember reading that it was normal but i know something isnt right . she has all power and dont give the slightest sign or hesitation.. my de has about 175,000 coutning oil never went longer than 5k and thats only if money tight usually every 3k oil changed and no odd looking color other than what dirty oil looks like no metal material or nothing. But recenly i had took her in to get my idle adjusted and the tech calls me an said she was bone dry of oil and add a quart... also he said bring it in for testin now all i remember as far as oil was the covers .. no werd signs of any thing faulty so i listen to him and did the quart the next week i changed the oil royal purple synthetic 5w30 always .. i had this car from 2002 september . dealer only touched this car when things like my wheel bearing was relpalced.. every time she passed.. This oil is driving me nuts. i smell it sometimes and my guage i reads low thats with the oil ruuning pass 3k to 5k like i said only hard times . When i do fresh oil change the guage is fully funitonal and looks accurate compared to dirty oil and i know wit drity oil it can be inaccurate aswell just need some pin points on where to go but oil pump last on my mind i really need to do the covers tho . i see oil seeping thru the side .. never was there before this might be my problem.. been out of school for so long washed my knowlege away fors knowlege of cars.... me dont write service repair..

 

Ok I refuse to read this headache inducing poster

 

So....what were you using the second time? Still typing on stupid ish?

 

Stop typing like this, then I'll help.

 

Guy,

Im not gunna be part of the grammar natzi's... Just some advice, if you dont write out your threads in a way that others can coprehend you are going to be made fun of...

Now as for your oil problem, it is clear that oil is seeping through your valve covers and into your spark plugs. Why haven't you changed both of your vc gaskets if you knew this was a problem? You might aswell replace both of them. The older your vehicle gets, the more likely gaskets and other parts wear out and need to be replaced. It's inevitable with high mileage.

Has it not occurred to you that by not changing them out you are burning oil and is probably the reason your adding oil constantly?

My advice (im not a nissan tech but this is what I would do) Change out your valve cover gaskets. Do a complete tune up: oil change, filter, spark plugs. Check your oil level when the car sits at a leveled out surface. I would not continue to drive it until the problem is solved if I were you.

I hope this helps and your problem is not to serious. (yoda voice)Take this with you, need it for your journey you will:

ahhh this thread was some funny sh*t but . just bringing it back to the topic. my oil problem has been solved , i came up on some rev up valve covers wit about 12k . the spark plugs o rigns seals are perfect. so i put those on and installed new vc gaskets and replaced my hose that goes to both vc's and thats all she wrote my oil has improve dont smell that oil burnt stinch no more and the oil gauge is very responcesive and on top of that all spark plug chambers are clean of oil (non) so this made my day i am pround to have gotten this done. @ 175,000. it time to pay attention to the almighty de . just noticed my hoses are beggin to get up graded to silcone so that will bee coming soon. the oem stuff played its part.. thanks guys and thanks for the kick a_ _ flamage specail edd comments ....
