So last week I was looking for help diagnosing why my car decided to stop working with no indication of any trouble...
Well, it wasn't what I expected at all...I was glaring at my timing chain trying to find out if there was any way it could've jumped, but the tensioner was fine and it looked lined up, and then I noticed something odd as i looked up - one intake valve for cyl 2 was open and the other was closed.
"That can't be right..."
So I climb up above the engine and look down, and sure enough, right by the exhaust valve lobe for the second cylinder, the camshaft is snapped in two. That explains pretty much everything, including how it would run on one cylinder as the timing was fine and it still worked for cylinder 1.So, I have to find a new camshaft. I'll start looking around junkyards for one...Is there anything else I need for this swap? never done one before. I figure the rocker arms and cam gear should be fine and i'll just need to take everything apart and put in the new one. I can't find any tutorials on this though - so any advice is appreciated.
And I have to hope and pray that the one valve thats stuck open didn't get bent by the piston. Anyone have experience with SOHC KA's losing timing? Is the clearance on the intake valves so tight that they get hit or should I be alright?
