@lindsaybercosky: I’ve dreaded doing this repair but it gaves me a perfect excuse to add more power and put big shiny parts on 😂 I was chasing a cooling issue in this car for a bit. Somedays it would be fine others it would push all coolant out of the reservoir and bubble into the tank. I put pressure to the system and immediately heard the leak at the back of the passenger side head. This is a retired police car which i can imagine had a hard 40k miles. The simple fix would of been just to put new gaskets in but thats not me. I’m doing performance heads, a big cam, big intake manifold and bigger injectors. A few parts are on back order from Edelbrock so stay tuned for the finished product :)
