99 rav4 loud ticking sound in valve train, no oil coming tk

[sekou876]

Hello, the head gasket on my 99 rav4 was blown. The head gasket was replaced but now there is loud ticking noise in the valve train. When I removed the valve cover and turned the engine over, I didn't notice any oil coming to the head. Before checking the oil pan strainer, i removed the oil filter and turned the engine over again and I could see oil be pump through the hole for the filter. Could someone let me know where in the head would I expect to see oil coming out if everything was working properly
