Blew My 240 Engine Today :(

[nissan240sx95]

So i recently purchased a convertible 240sx, after lots of little problems i finally had the car running and looking pretty damn good for under a months work. a friend of mine who works at my job (autozone) recommended i put seafoams in the car and run it for 500 miles, then change the oil. I did, put in new synthetic blend oil with a bottle of lucas, and 3 days later heard this horible knocking while driving. pulled over and realized that i had no oil on my dip stick. i filled it back up, but since then ive been smelling this horrible burning smell, my cars been knocking horribly, and it doenst start sometimes, and if it does, it dies 2 min later

i think im f u c k e d..... any one have any brilliant ideas or any suggestions....i dont have alote of money to jus drop and sr20 in this car or take it somwhere to have the engine rebuilt, plus im not to fond of how this trannies been acting.....an ideas anyone???

um yea get a new engine and trans, as much as you hate to hear it. ill bet that a gasket was gunked up and thats what was sealin it so once you seafoamed it it cleaned that gunk and wam big oil leak which is why you didnt have oil on the stick. so replace or rebuild my friend. but id drop the pan and just check the oil pump screen and see if its clogged, that could be stoppin enough oil from getting to the head and makin it knock.

also synthetic oil in high mile engines is not a good idea, natural oil has a larger molecule which creates grooves in the cylinder walls, smaller synthetic molecules blast through these grooves like a rocket. making you burn oil after the synthetic switch.

its synthetic blend, and ive been running it in the car with no leaks or burning since i bought it 3 weeks ago. but i thank you for your input.

thats actually what i heard from a few people, but checking the oil screen sounds like a great idea.

UPDATE: car starts everytime when cold, and runs and drives great, then after it starts to warm up it starts ticking really loud, then dies and refuses to start until its cold again... im going to keep searching, but if anyone has ever experienced this or even has any ideas please throw them out there, im gunna check my oil screen tomorrow...

find an SR20 and sell your block for scrap on the forums. If your found a new ka power plant, you'd probably just have to convert to manual any ways which would be extra work

You did change the filter when you changed the oil right?

I would give it one last try with new filter and fresh regular oil before you give up on the engine. It may work well enough to keep you on the road while you get ready for the swap or rebuild.

Once it starts knocking regularly it is only a matter of time before its done. Could be 2 minutes or 2 years but it will go.

you can save your self the 3 grand of coin you will loose with a swap..if your not racing..you dont need a swapp...just rebuild it with an OEM rebuild kit..its like 200 to 300 bucks and your time...shouldent take more than a week and some friends/tools..good luck what ever you decide.

Does that price include any machine work needed or is that parts only?

[liquid_cool]

just parts...oem only too..and off of ebay..lol..buy ya..you can rebuild for that if ya do the basics at home and know how too..but it would be sloppy stock...tolorances with in {0.25mm}...
