Hello All,

Recently I've developed an oil leak. I cleaned the underside and added a uv dye to the oil of the car. I traced the leak down the the front of the car. Specifically, it's collecting on the underside of the AC compressor. I'm pretty sure it's oil due to the color and light florescence. I don't know what it could be. I've replaced VVT gaskets and had another race shop replace the valve covers and gaskets with CZP aluminum covers. Here's a link to the video. Any ideas? Only thing i can think is a bad valve cover install or leaking dipstick, but I don't know. Any advice is appreciated.

 

I would clean the oil off again and re-tighten all valve cover bolts using the recommended sequence. I know theres many Z owners that have used these aluminum covers over OEM with no issues but Ive also heard of some owners having issues with these. Make sure the oil dip stick is pushed in all the way in. Theres also a O-ring there that can also leak. Good luck

 

Make sure your dipstick isn't being pushed out of the tube by crankcase pressure. Then, check the front inspection covers for leaks.
