Cracked Camshaft Cap

Post by kzaske »

I need some options. While trying to set the left head to it's timing mark there were three loud cracks. :oops: I was afraid I broke the head and let it sit for almost a month before I could bring myself to actually take it apart to see what I and my son did. I don't have much of a budget (about $100.00) please keep that in mind.
When I got the head off and took the rocker rods off I saw the crack on the intake side of the camshaft cap. The crack does not extend all the way through the ends, so there is no danger of an oil leak.
I have been advised that J-B Weld (High Temp) would take care of it, but there is about a 2mm offset in the middle of the crack where the two center bolts fit. I have found a "machine shop" head that I can buy which will take almost my entire budget. I am not sure the cap will be intact. I also need to find a gasket for the cap, any ideas where I can find one will be greatly appreciated. Photos below.

Not a mechanic, but would replace vs repair. Assuming this is an EJ253 engine, could probably pull parts from a gen-3 NA legacy?

I'm a mechanic, and I wouldn't trust that with a "repair". You may run into problems with bore matching if using a used cap. Dennis
