bent valves?
long story short... keyway broke...crank got stripped.... valves got bent...
here is my question...
when i bring the head into a machine shop to get a valve job... do i need to bring them in NEW VALVES or are they going to repair the ones that got bent?

im having trouble figuring out why the valves got bent from the keyway stripping, was the cam gear key way?, did the crank pulley fall off and you kept driving, i know my crank pulley fell off one time coming to a red light, it was the most awful sound ever.

both keyways that sit on the crankshaft busted....the key for the pully and the key for the sproket thingy that runs the timing belt... when the timing belt no longer was able to turn the cams... im sure it left a total of 8 valves lowered when the pistons were still able to pump, bottom end was moving...head stopped... hence...bent valves...
thats just what the shop told me.. makes sence... but i pulled the head off yesterday and saw no signs of bent valves... not sure if that is something you can just tell from looking at it or not... but i was told i would need a valve job to correct this issue...

Have a shop check the valves to see which ones might be bent. They will have to pull the valve springs to check. You might be able to see marking on the valve relief area of the pistons, if the valves touched them- - - or not.

Where else but ebay. I got full ferrea valve train off there pretty dam cheap. I put all new guides, seals and locks in while I had the head rebuilt.

Re: (blindingxenon)
damn nice price... i looked at the head pretty goot... dont really look like anything is bent.... all the valves seat like nothing happened... i wonder if there is a chance that they didnt get bent when the crank got ***'d... any way to tell for sure before i take it to the machine shop tomorrow?

I havent heard anything bad on the Omni valve train.. its been out for well over a year. Only thing you need to do is watch the retainers ( which you should do anyways when you are running titanium retainers.)
