I've had my engine lid repainted previously and since then there has been a slow leak anytime it rains. When looking at the lid itself it appears that everything is as it should be. Nothing appears to be missing or loose. After raining, when you open the hood there is water that has collected on the cylinder head where the spark plugs connect, specifically above #3 and #4 on the right side to the point where the spark plug is submerged. I'd take it to the original body shop, but I had this work done in Los Angeles (I'm in San Francisco now) and it's a bit far for them to take a look at. I've tried having my local mechanic look at it and he can't seem to figure out where the water is seeping in. The water sitting like this has been rusting my spark plugs which I've had to replace them once already since this began. We've put a water hose directly on that tray in the center of the engine lid and water is funneling down properly. Is there a seal between the mid-read brake light on the engine lid? I'm wondering if it's missing or broken? My mechanic says if I could provide him a diagram of the engine lid it would help him better diagnose. Does anyone have a copy they could forward? It would be greatly appreciated!
