Re: 4JB1 rebuild
It might be a bit late, but the liners are much easier to get in, less likely to be deformed and/or scratched if you put them in a Freezer (in bag to keep out moisture) or use dry ice.... just push in, with maybe a light tap at the end.

Don't worry they went in easy, I had the block in the hot wash for about 3 hours to get the dirt off before I pushed them in, I worked out on the last two that I just needed to slide em in then a little tap with the soft hammer and they were in.

The intake plenum on this was heavily caked with oil gum, this was from the blown engine which would have been in good condition before it went for a swim, the valves were in the same engine... I tried everything to get it out, degreaser, burning, turps, and hot wash for hours.
