My old gal has a mint condition 1994 Nissan Bluebird (auto 2.4L with around 160k kays) which basically gets driven to the shops once a week and spends the rest of the time in the garage. (I drive a Lexus IS300 so sorry if I mistake the chassis code engine code details)
Six months ago the following occured:
The car has been a dream to own since new it has never caused any problems, but on xmas eve my old gal got stuck @ the shopping centre and couldn't start the car.
A NRMA roadside tech came out looked at the plugs, added fuel to the car, looked at the air flow meter, unscrewed and cleaned the distributor cap but no matter what the technician tried the car would crank but wouldn't fire up. The car was towed to a local auto electrician.
Today the auto electrician rang to say the car was ready, and explained that the problem was caused by the distributor being full of oil, which must be due to a faulty/worn seal somewhere in the distributor. I mentioned that when the NRMA tech took the distributor cap off there was no oil in there so it seems strange that after the car was towed to the auto electrician and hadn't been driven that it would suddenly fill will oil... He blinked and ignored me and mentioned that the current fix is only temporary which might even last a few months but since they have never seen this problem before he really cant judge how long it will be ok for.
He recommended that we bring the car back to try and rebuild/reseal the distributor if they can in fact pull the K24 distributor down to try and prevent the oil from leaking into the distributor again When the car was taken back, he said the oil breather was blocked and it was right to go.
Six months later it is occuring again and there is approx a few hundred ml of oil leaked down from the bottom of the dizzy.
Is this a common fault with the K24, and is their rebuild kits as such readily available?
Also I changed the oil laste June to castrol edge 5W30 (I know its thin but the manual stated 10W30) surely this isnt the issue?
