Title: Is this piston OK to re-use?
Post by: Jetmugg on May 19, 2016, 02:51:19 pm: I am in the midst of a re-do for my 1.5L "Franken" engine. Block will go to the machine shop to see if it will clean up with a honing, or if it needs to be bored to the next oversize.

Meanwhile, I'm trying to figure out if I can re-use this piston, or if I should buy a new one.

Please let me know what you think.

Steve.

Apparently though, he never returned from rehab.

i.e. I wouldn't reinstall but BI would....

Post by: Jetmugg on May 23, 2016, 03:11:16 pm: Here's the path I'm on.....

I have placed an order with Pauter Machine for a set of custom connecting rods to work with the 1.5L crank, and 1.6TD pistons. (49mm big end, 24mm small end, 139.4mm center to center).

My block may need to be bored to +1mm size, and as many of us know, oversized 1.5 pistons are unobtanium in the +1mm size.

1.6TD pistons are relatively easy to come by, so that's the route I have chosen. Custom rods to work with the 1.6 TD pistons.

Will be taking the block to the machine shop later this week.

Post by: RabbitJockey on May 24, 2016, 07:41:17 am: in my experience the coke bottle does a slightly better job than pepsi, but i have also heard people say that birch beer bottles are the best, but i've never tried tried one personally.
