I let my car go tonight around 800 km's on rebuild and after I let off it started knocking For about 30 sec's then Went away :cry2: :cry2:
Dam I knew something would go wrong I knew it !! Oh ya the C/F dual friction wont hold. Starts to slip a 4500 rpm I give up, I quit !!

 

Thats terrible man...

Knocking or pinging? you gotta let us know, pinging is fairly minor, however, a knock sounds more related to either oil starvation or rod knock (unlikely in a rebuild)

it is cold, so if you're running too thick of an oil might have a problem there. and to make a CF DF slip takes power, how much are you running... but those need a good looong work in, if you get on them too early they will be a paperweight.

Let us know, and im really sorry to hear that man.

 

why would your CFDF be slipping? I just bought a CFDF and it better not slip. Heck, i am running on a stock clutch now. I wouldn't want to take out a stock clutch, put in an aftermarket and have it slip. i would be pretty pissed.

 

Awwwww man that freakin sucks dude! I hope its nothing major. Just check all the vitals and do a compression test before you go any further. Keep us updated.

Clutch was fine for 3 night's I took it easy. It was in the car before for about 500 km's, Flywheel resurfaced with this rebuilt-eng. So car was up to temp Stopped floored It "HOLELY SH#T The car is Crazy" I am nut's, But this thing was all over, 2nd gear ET street's No traction. I know it's cold out But man this thing is Crazy. Glad I bought that 7 inch crank pulley. But anyway I let off came to a stop and Knocking and ticking like crazy. For about 30 sec's Tops. Then Knocking went away but the Ticky tick stayed ?? So I thought OH well Nothing new just my 3rd eng No biggy. So I let it rip some more ! CAR pulls and PULLS Dam I bet It Run's Mid to Low 11's So anyway Clutch starts slipping in 2nd at about 4500-5000 rpm's Wont stop so I say screw it I'll bring it home. So that's That I guess Time to take the bus LOL :cry2:

 

OK so I start it up this afternoon Knocks for a sec when started then is gone ????? Still run's Just ticking ??? Clutch still F&*KED.

What heads, lifters type, etc.? Are you still running the break in oil?
