I have found the TOUGHEST Corolla out there...maybe even the toughest factory Toyota motor....
My best friend drives a KE70 (4kc motor, 1.3 carby) like me, but an 83 model and 4spd manual....Coming home from a party, I was kinda drunk and we dropped his missus off at her house. Driving along the highway home, the engine decided to just run rough as guts for no particular reason....No backing on.off of the throttle, no bangs/pops etc...So we pulled over and were hearing some very nasty noises with the bonnet up in the dark...
A quick (would have been quicker if I was sober....) call to the RACV boys and they showed up reasonably quickly. With his help, a torch and a dropsheet, we discovered that a piston didnt like being inside the block anymore and had decided to break free through the bottom of the block....We later found that a lack of oil had caused a bearing to fail and the piston/conrod left to continue its downward motion.....And air condition the block...
Funny thing was...tho it went as rough as guts, it was still running and drivable!! I kid you not we drove about 12kms back to his house with the RACV van behind us (unable to tow). Had to rev it more but yeah....By the way he's in the market for anew car...anyone in Vic with a decent car for about 3grand...let me know okay?
Cheers
