Gavin Posted October 2, 2006 Share Posted October 2, 2006 Finally got around to tearing down the 83 ZX turbo. We baught the car for 800 dollars and drove it home from NC. Of course, it was too good to be true, as we fully expected. When we baught it it overboosted because the HKS boost controller was hooked up wrong, which was easily fixed. But as we now know it was also under fueled thanks to a bad fuel pump! So the car was driven home like that and fixed soon after. A few weeks later, my father starts it up and notices (thank god) that there is no oil pressure. We replaced the oil pump and inspected the shaft that goes between it and the dissy, tried a mechanical oil pressure gauge, and nothing. At one point we left the spark plugs out and the next morning Cyl. #6 was filled with coolant. So there it sat for a while till I got arround to it.. Untill a couple of days ago. Heres what it looks like, didnt do any cleaning except syphoning the coolant off of cyl 6- http://homepage.mac.com/gavinwilliams/Turbo/1.jpg http://homepage.mac.com/gavinwilliams/Turbo/3.jpg http://homepage.mac.com/gavinwilliams/Turbo/4.jpg http://homepage.mac.com/gavinwilliams/Turbo/5.jpg Only scoring I can see, without rotating the crank, is on cyl 2. You cant feel it with your finger. http://homepage.mac.com/gavinwilliams/Turbo/2.jpgBTW thats just a piece of gunk, not metal, on the piston there. So what could have caused my oil problem? Could coolant have gunked up the works? Havent looked at the oil inlet under the oil pan yet, somehow I doubt its failed though.. Im having trouble getting it off, is it possible to get the oil pan out without lifting the entire engine? Does my engine look to be in terrible shape? What should I do about the corrosion? Whats the best way to flush the oil system? Thanks a lot. Quote Link to comment Share on other sites More sharing options...
Gavin Posted October 3, 2006 Author Share Posted October 3, 2006 Any input or thaughts are welcome... I'm mainly worried about making sure it gets oil pressure when I get it together with the new turbo and start it up. Quote Link to comment Share on other sites More sharing options...
naviathan Posted October 3, 2006 Share Posted October 3, 2006 Clean it, clean it, clean it. Make sure all the holes line up on the new gasket as well. The scoring on the number two piston is a little odd. Looks like something fell in the cylinder and sat there for a while to do that. Otherwise, if you clean it up and make sure the oil passages are clear it should be fine. Quote Link to comment Share on other sites More sharing options...
Gavin Posted October 3, 2006 Author Share Posted October 3, 2006 Sounds good. So whats the best way to go about cleaning it and clearing out the passages? Thanks Quote Link to comment Share on other sites More sharing options...
