we pulled apart the 4BD-1T last night to get ready to have the sleeves pulled. Bill (88tlc - who's engine it is) scored a PDF from someone on this site (thanks again who ever that was) and printed it off.. Says its been invaluable... Anyway, it says you need to remove the whole front cover to get the crank out... But we were luckily able to get it out, just barely, by removing the bearing caps and oil pan only..
anyway I'll post up pics and details of the rebuild as they come along. Bill is saying he can find rebuilds for about $2G in parts alone
Expensive!!!
