datsunlover Posted June 10, 2005 Share Posted June 10, 2005 I think you'd be lucky to get $100.. init's current condition. With 30psi across the board I'm thinking it needs rings, bad. One of those things though, you don't know for sure till you tear the thing down.. Does it even run at this point? In good runing condition I supose you could get $500-$1000 depending on the person who wants it.. Quote Link to comment Share on other sites More sharing options...
jonnymrp Posted June 10, 2005 Author Share Posted June 10, 2005 no it doesent run. everything is there though spark, gas, theres just not enough compression to get any real heat in the cylinders so it will not kick over. like i said i dont relly care about the state of the engine im more just wondering if its a common thing to see on these cars Quote Link to comment Share on other sites More sharing options...
RacnJsn95 Posted June 10, 2005 Share Posted June 10, 2005 Has it been sitting for a while? Quote Link to comment Share on other sites More sharing options...
Guest billyzbear Posted June 14, 2005 Share Posted June 14, 2005 You may want to check valve clearance. How fast is the motor turning? You could also do a wet test. Put a cap full of oil in the cyl and then check compression. That will find out if it's the rings. Quote Link to comment Share on other sites More sharing options...
Guest bastaad525 Posted June 14, 2005 Share Posted June 14, 2005 Stock L28 in unknow/not running condition isn't going to sell for much. Even if it is running most I've ever seen an L28 sell for is like $300. The trans might add $100. Quote Link to comment Share on other sites More sharing options...
