hi guys.. i recently bought a 1987 na rx7 with 150k miles on the motor
everything seems okay cept there's oil in the antifreeze compartment, which i've read is a problem, but i do not know the extent of the problem because the article did not go into detail about it, i was just happy it did not have the hesitation at 3800 rpm

can someone tell me if this problem is very bad or easily repaired or needs to be repaired at all?
thanks in advance!

I SERIOUSLY doubt that you really have oil in your anti-freeze. You probably just have gunk in there that is "oily like stuff"... it is especially common if you use Redline Water Wetter. The best thing to do would be to flush your cooling system and see if it comes back. (I would expect some to still exist even after flushing, but it should be less)

BTW- I freaked out with my car and thought the same thing when I first got it...

Good luck,

XiaoMing

thanks

hhmm *bumps thread up a bit*
anyone else have any ideas?
cuz this is quite a dirty layer floating above my antifreeze
i just wanna be sure there's no problem w/ my engine
i dont wanna hafta spend 40 bux to flush the thing and then have more oil leaking out

is this a major problem if it is?

If you have oil in your coolant, that generally means that your coolant seals are going out, or they already have, and your engine needs rebuilt or replaced. One way to check this is to start the engine with the radiator cap removed, and see if you get bubbles coming out, or coolant shooting out. If all is good, when you rev the engine, the coolant should get sucked down, not fly out. Good luck.

Pull your radiator cap off , pull off the spark plug wires, and start your engine. If the coolant flies in the air, your motor is blown/Water seals or jackets you amy call them are destroyed. Time for an engine rebuild if you find the coolant shooting in the air when you start it.

If it doesn't, then I don't know how in the hell it is getting in there, other than that it has a broken water seal/jacket.

I think this is what happened to your engine. Do you see the black smudge? Water jacket going out. I may be wrong abotu your car though. Your description sounds like my last motor that went south from a water jacket. Oil in the coolent.

IM gonna be doing a small 'personal' inspection. So leaving the cap off the radiator and starting the engine should reveal NO coolant shooting/coming out? alrite i'll check that out too. also, if you leave the oil cap off at all when you start, is anything supposed to happen?

I know of a few checks..but what checks could i do similar to this one (checkin engine w/out dissassembly or driving, just turning on, pumping gas..clutch...etc..) im worried about her becuase i cant afford a rebuild, but my engine is only 4 years old (new) so i dont know...damn rotarys...always making you worry :o

heh if u changed oil at every 3k miles ur car shud be fine :P
hhmm so do i HAFTA unplug the spark plug wires or can i try the radiator trick w/o doing that?
cuz wouldnt i flood the engine w/o the sparkplugs?

I think what he means is try to crank over the engine and not have it fire. Remove the fuel pump fuse from the main small fuse block under the hood so your car will not flood.
