Snapped camshaft
For background, stock 17’ wrx. I was driving when suddenly I got severe engine vibration and loss of power. Had codes for a camshaft position correlationI and misfire on cylinder 4. I feared I spun a bearing but wanted to tear into the engine before I went to the worst case scenario.
Pulled off the drivers side valve cover and found the cap on the exhaust cam was loose, uh oh. Now that I was this far I figured I’d check the valves and piston to see if I bent anything. Turns out I did not somehow, when the cam broke I’m assuming the valves closed before the piston came TDC.
Now for repairs, I understand the cams are machined with the housing they sit in with there being no bearings, where does one go about ordering replacements. I’ve been able to find replacement cams and I can probably find a rocker box and caps but should I be concerned about getting cams and the housing separately? Does anywhere sell the whole valve cover, rocker box, and camshafts in one unit that just bolts on to the head?
