HB280ZT Posted February 15, 2007 Share Posted February 15, 2007 Hi All, OK here is the basic information: 82 280ZXT motor with a blown head, see earlier theard: http://forums.hybridz.org/showthread.php?t=119166 it has an N42 head with a turbo cam. So here is the problem. I picked up a 2mm metal head gasket and installed it. I then tried to install the timing gear on the cam but it would not fit. So I then pulled the front cover and removed the tensioner but the chain would still not fit. So I pulled the curved chain guide and then the chain would install on the cam. But now I can not install 1 of the screws on the chain guide. Basically the chain is to tight all the way around!! So what can I do! Do I need to get a longer chain?? If so what is the part number? I really need to get this motor together so that I can run it at VIR next weekend. Thanks for the help! HB280ZT Quote Link to comment Share on other sites More sharing options...
slownrusty Posted February 15, 2007 Share Posted February 15, 2007 Did you try making a revolution or two by hand with the cam sprocket and the chain installed to see if it will pick-up the slack you need? Yasin Quote Link to comment Share on other sites More sharing options...

Via text, we could be here for days muddling through interpretations, descriptions, etc… If you can post pics, I’m sure we can quickly solve this issue.

HB280ZT Posted February 15, 2007 Author Share Posted February 15, 2007 Yasin, Thanks for the information. Now everything fits like it should. This is why I really like this site. You ask for help and someone comes through with some great advice. Thanks again for the help. Now I just need to get the gaskets that I have on order tomorrow and I can start putting the motor back together again. HB280ZT Quote Link to comment Share on other sites More sharing options...
slownrusty Posted February 15, 2007 Share Posted February 15, 2007 My pleasure - glad to help! Sometimes the chain can be very tight once initially fitted and making a revolution or two with it mocked-up will "break-in" the slack needed.
