loud clicking'sh noise July 19, 2006, 09:04:06 AM Ok, I'll start off by saying I'm not the biggest gear head so my engine knowledge is limited...In my car I have a Carb 302 with the following:650 holly Double pumper carb351 alluminum headsalluminum headersGM distributorDual hi-flow cat exaust with drops before the rear axel Last night after work i was driving my T-bird, and i stopped for a couple min... When i Started the car again I started getting this very loud clicking noise as the engine ran aswell as when i'd hit the accellerator. (Kinda like someone tapping sheet metal with a hammer real fast.) So I check my oil and I did infact need some. So after I put my oil in its still making that loud noise... I tightend my rocker covers on the one side because I saw some small flames escaping at the back. Still with the noise... Driving the car home; whenever I'd downshift out of gear not only would it click but I'd also get this kinda backfire sound aswell... My cat's have been acting up a bit for the last week or so and I think it might just be them but i'm not sure at all... Please note this engine is brand new and due for its first oil change at the end of the week... Anyone have any ideas? Quote Selected

loud clicking'sh noise Reply #2 – July 19, 2006, 09:33:04 AM Flames like, cumbustion gases shooting out around the gasket on the rocker cover. It wasnt huge flames or anything, just little spirts from around the gasket. Quote Selected

loud clicking'sh noise Reply #7 – July 21, 2006, 12:57:48 AM Well, it turns out that I am very lucky indeed... it was the last header bolt on the driver side... and with the distance I drove it after all of that happened I'm even luckier I didnt burn out the gasket (thank god for the 200$ set)... so let that be a lesson to everyone else with alluminum headers... TIGHTEN YOUR BOLTS OR ATLEAST CHECK THEM REGULARILY! Quote Selected
