Guest rollinwardle Posted September 26, 2006 Share Posted September 26, 2006 Hi - I'm looking at a 1978 280z that someone is selling locally. I've yet to look at the car, but the owner says the car suffers from a STUCK VALVE. I'm wondering what a repair like this would cost or entail? I know the question is really vague, but I'm trying to get a ballpark estimate... And this question assumes everything else is okay with the car... Thanks for the help.. rolly Quote Link to comment Share on other sites More sharing options...
rustorbust Posted September 26, 2006 Share Posted September 26, 2006 this might sound crazy but if i remember right my uncle had the same problem on a 1980 chevy luv he told me to buy Mobile 1 fully synthetic oil( the $6-$7 a quart one) use that and run the car for a few mins and it sometimes sets it free it worked for him and since then he only uses mobile 1 =/ ive never tried it but he said that ♥♥♥♥ is magic Quote Link to comment Share on other sites More sharing options...
biohazard53188 Posted October 1, 2006 Share Posted October 1, 2006 As long as the car keeps getting older you will always be repairing it. Lets just say Zs arnt getting any newer. But for that issue you may want to give your local mechanic a call and get an estimate about the valve. Quote Link to comment Share on other sites More sharing options...
zeiss150 Posted October 3, 2006 Share Posted October 3, 2006 A stuck valve could be anything from a bent valve to a poped valve seat. or it could be just as simple as a miss adjusted rocker arm. the price for repair depends on if they have to pull the head. If they have to pull the head then you are gonna pay, If it can be fixed with a rocker arm adjustment then it should be cheap. If its a bent valve then you may have WAY BIGGER problems. If thats the case then you may have to have the entire engine rebuilt. I'm just giving you the worst case senerio, so you're not shocked if the mech tells you it'll be $3k to fix it (make sure thats for a total rebuild though... and even thats to much IMHO) If you are at all interested in Z engines I would refer to you a book named "how to build your nissan OHC engine" at the very least you'll know if the mech is ripping you off and at best you can fix the engine yourself. Good luck and keep us updated Quote Link to comment Share on other sites More sharing options...
