Ok so I just bought a 91 240sx DOHC with 275 thousand miles on it , it runs pretty good BUT it leaks oil and when I got it had 0 oil it Died the first time I tried to peel out so I dumped 4 quarts in and she ran like a top. Actually with a slipping clutch I ran my buddies 05 tiburon GT SE 6spd(cause he helped me go get the car so we figuered what the hell) we ran from a 25 roll and I stayed damn even untill I shifted into 4th and the clutch didnt catch but anyways to the point i just wanna drive it threw the winter and do a red top swap in the spring BUT i need this to run threw the winter, so I need to stop the oil leak. so heres what Ive come up:
Change Oil/ Change oil filter
Bought new clutch allready/ gunna turn the old flywheel
Change trans fluid
Check rear end ?
buy a ebay CAI to replace the old filter (seeing how its soo cheap)
Maybe a new oil pan????
Its allready got new brakes and rotors
So if you 240sx gurus could let me know what else needs to be done or special "problems" the 240s have..
Ohh and BTW my names Chris and I own a RSX type s as well thanks for the help

 

sounds like it runs WELL (sorry good/well thing is a pet peeve of mine) for having 275k on the odometer. i would do a basic tune up and get some new plugs and maybe top off brake clutch etc fluids.

 

can u give me a recommended spark plug and what gap please

 

Stock. If you are leaving the engine untouched, just use stock plugs. Go to the parts store and tell them what the car is. They will sell you pre-gapped plugs for your car.

 

i got the platinum bosch plugs when my car idled rough, they helped alot. cleaning the maf and injectors will help tremendously too

 

what are commone reasons why 240s leak oil? Im thinking its just the pan but I dunno till I really check it out. So cleaning the injectors and MAF helps alot, how do u clean the injectors? and the MAF for that matter LOL

 

you should locate the oil leak. get a flourescent dye kit or get a shop to find it for you.

 

Change out your rear seal, and the oil pan gasket. I would say change out your front seal as well but it takes too many hours. But the other 2 will get rid of the majority of your leaks.

 

I say swap time! Haha...BTW just cause I said swap doesnt mean I said SR...just wanted to clear that up

 

wow, thats a lot of miles, still running well! Thats NISMO Power for you. :-)
Honda is also a good car. ( your RSX )
Don't know about the oil, but i can say, listen to Big Vinnie, he's the authority around here.

I like your name Mr. Akina Speedstar #1

 

ill do that thanks for the help also thanks to everyone else for the quick replies. Im going to tune it up and do the clutch this weekend. Whats the fluid for the rear end?

 

red line to the limit
