@Thunderbolt..
Thanks dear for your appreciation...Its nice to know that you own an old corolla and still sticking with it (like me)as most people dont like to keep old models and always looking forward towards newer ones.But I tell you that this 82 corolla is still my favourite car and I still love/enjoy to drive it and it gives such smooth and reliable ride that very few new cars offer.Our new corolla have inbuilt brake fault and other stability broblems....front cv joints go if dust boot is damaged and replacement is expensive..But these old cars (rear wheel drive)have no such problems and are real work horses.Having electronic ignition is very good in 4k engine and I am also thinking to go for it.Oil and filters play a great role in engine life..But I am not able to find genuine oil/air filter for 4k any more...next best is VIC oil and GUARD air filter which are being used as there is no other option...
I maintained the whole record for about 20 years for all the oil/filter changes,plugs,points,condenser,fuel filters,tyres and what ever I did in this 82 corolla as per maintainence..your 4k is going to last another 100000 kms INSHALLAH,as you are taking good care of it..
