my buddy has a 94 Si honda del sol, we decided to race, we raced and as i past him in forth gear and shifted into 5th, i looked down at my guages and my oil pressure was at zero, i immediately shut it down pushed the clutch in,costed to a stop,popped the hood and checked the oil, the oil was right on the full mark, no oil is leaking anywhere from my engine,not a drop, wtf? i start it back up and the oil pressure is normal at idle and at 60 mph. go back to my buddies house check everything out and while its idling it start to hesitate, so i shut it off check everything the best i could, oil is at the full mark, go to start it back up and the engine feels like its seized up, felt like the starter was stuck, finally started up and now its runing on one rotor, im not sure if its the front or rear rotor that isnt running, i drove it down the road and back and about **** myself, it felt like i had about 50 hp. now the question is after i shut it down the first time and started it back up it was fine until i shut it off at my friends house? what gives? i think its an apex seal,damnit! lol its about 8 degrees out of the wind so i didnt feel like ripping out the spark plugs out and checking to see if they apex seals are still there, prior to all of this the car overheated about 7 months ago because the thermostat started acting funny, so maybe the rotor housing warped and just decided to **** on me? car only has 92,000 miles on it now, 64,000 when i bought it. thanks for reading all this and for the info, later



SEMPER FI

maybe something came unhooked,wire/vacuum line? i dunno? lost compression? please help,lol https://www.nopistons.com/forums/pub...IR#>/dunno.gif https://www.nopistons.com/forums/pub...R#>/violin.gif https://www.nopistons.com/forums/pub...R#>/violin.gif https://www.nopistons.com/forums/pub...R#>/violin.gif

If you got the car to start back up your front rotor is fine.. for some reason a rotary will run without the rear rotor.. (hense mine wouldn't run when i blew the front *doh* ) That's weird that you lost oil pressure though... like oil pump failure yet it was fine after you started again.. hehe yea check all your vacuum lines.. make sure your OMP is working

OMP? i dont know that abreviation? it thats not working it wont run right?

Did you check compression?

That sucks man..

maybe (cuz I've had similar probs.).....



#1 the oil pressure sender wire can (and will/might) get loose and make a shitty connection.

(you might not have really lost oil pressure at all I believe)

#2 the rear rotors seem to get coolant seal leaks (I have a '83 and a '86 whithrear coolant seal leak probs.) and this will cause the rear rotor (usually rear) to not start initially but eventually after a few seconds to a couple mins.



check to see if your overflow bottle for the radiator is bubbling more than usual if so thats exaust gas from the rear rotor blowing backwards into the water jacket through the leak.



sorry



I hope I'm wrong.

what is OMP?????

oil metering pump? I think...

yeah your right thats what it is.

The omp(oil metering pump) squrts oil into the intake air streem to lubricate the rotors.
