Re: rough idle and rattle when starting
I'd like to know too. I've heard the NA engines can be pretty reliable but it seems not many make it over 200k. Im wondering if it's just the internals cant last or an external source like splitting OMP lines that prevent proper lubrication. My 86 has 215k and i just tore the top half down to replace intake gaskets and split metering lines. The oil doesnt turn very dark or get burned during use. It's still gold and full after 500 miles. I know nissan 4 bangers made around the time of the FC will last about 200k before timing chains and valve seals go but it's a simple fix (bout the same cost to overhaul a rotary) and it's good to go for another 200k. Or honda engines this age, about 200k they need to be re-ringed and new valve seals and good to go.. kinda wierd how they all work together.

Re: rough idle and rattle when starting
Hmm... mine's 295k now and still running strong, compression reading is between 88 to 97 when the engine was tested around 290k.

Re: rough idle and rattle when starting
Hey Guys im new here and my 87 has about 106k on it and idles and runs really rough feels comparable to losing a piston or 2 in a 4 cylinder any idea to what the cause may be ? already changed fuel filter spark plugs and wires and re-grounded ecu any help would be greatly appreciated.

As for running really rough, could you explain a bit more? It could be a number of different things. |
Re: rough idle and rattle when starting
not sure how to explain it other then it feels like a rotor is dead or something but i have compression and spark. as of today i cant get it to idle or stay runnning it was running kinda sounded like a go kart or a 4stroke dirt bike. had no power and was shaking really bad even at i higher rpm not sure what rpm my tach doesnt work and then it shut off now i cant get it to run for more then 15 seconds. i need a rotary pro lol
