siteunseen Posted July 1, 2015 Share #1 Posted July 1, 2015 I've got my block and am ready for assembly. Should I put the crank and pistons in before paint or after? I use Permatex assembly lube and I'm scared I'll get it onto the new paint. I was thinking install the crank and pistons, paint the block then put the expansion plugs in. I could put 1 coat on then assemble, shoot it again? Advise me, please!Cliff Link to comment https://www.classiczcars.com/topic/51764-block-painting-question/ Share on other sites More sharing options...
Jarvo2 Posted July 1, 2015 Share #2 Posted July 1, 2015 I painted my block before any assembly and am quite happy with the results. You are going to get some form of fluid on your freshly painted block, just need to clean it up right away! http://jarvas240z.blogspot.com/2014/11/block-cleanup-and-preparation-for.html 1 Link to comment https://www.classiczcars.com/topic/51764-block-painting-question/#findComment-473030 Share on other sites More sharing options...
Jeff G 78 Posted July 3, 2015 Share #3 Posted July 3, 2015 Paint the block bare. Use good engine paint and it will not get damaged from oils, lube, etc. If you wait to paint it, you will likely get some oils on the block and the paint will not adhere. 1 Link to comment https://www.classiczcars.com/topic/51764-block-painting-question/#findComment-473142 Share on other sites More sharing options...
jfa.series1 Posted July 3, 2015 Share #4 Posted July 3, 2015 +1 on Jeff's recommendation. My builder installed the expansion / freeze plugs, then painted the block. No painting during assembly.

Martzedcars Posted November 5, 2015 Share #5 Posted November 5, 2015 This week i bought an engine from a partly disassembled datsun 240z.. including the very rare european 240z 5 speed gearbox in good condition for a set that has been meandering on a scrap yard..Nice story to it.. the yard had to move and everything had to go and from under a lot of parts came this car, laying there for 25 or more year! The son asked his dad.. shall i take the engine out or put it completely into the shredder? Luckely he took it out.. I'm very happy that i could buy this increasingly rare engine block, incl. starter, manifolds, generator, etc. It is a late 240z block, sn:180722 or around there.. My question: It has a red engine block.. is that Original or are all 240z blocks that special blue color? I'm shure it came out of a 240Z not a 260.. Also its a euro version! No airpump or air inlets on the exhaust manifold etc.... makes it pretty rare! My '71 240z has a blue engineblock.. is red not Original?
