When me and my middle son went to the Ratsun meet in Port Orchard this summer, he took pictures of Elmerfudpuckers 510 wagon and my oldest son saw it. He said that if he was to get a Datsun it would be one like that ..Well if you didn`t know 1979 510 wagons very seldom are on craigslist ,or anywhere for that matter. But i was looking through engine section on here and a guy was asking how to fix head problem. He got some help then the " help " turned mean when they learned he was fixing car for ex-wife or something.......Sooo i sent him a PM asking what he was going to do with car if not fix it. ( something the other members could have done if the TRULY wanted to save every Datsun and not just give lip service ...........But i digress..... ...Went to Renton the next day and picked up wagon for $100. from this old guy that was really into restoring classic Vespas but just didn`t have much Datsun knowledge. The matchbox dizzy was worth the price to me and it had brand new brakes,,,brand frickin new all around.. .....Car has spent a few months lounging in front of gee-roge and son pulled engine out of 76 620 for head but it looked pretty ugly so did some trading for a closed chamber W58 and some Superlites ...He has since pulled motor from car and i helped him disassemble because of no cross hatch marks but it looks like it has Machinist marks on everything even piston tops ( and the numbers don`t match which usually means slight different bore sizes ) but i have several others so maybe not a real problem.. The day we picked it up Test fitting wheels Truck engine disassemble emission removal........ AIR pump was frozen Car had slight head gasket leak These pictures show why we removed engine....(hint ) it`s green Color code bitches
