Re: Intermittent tapping on cold start.

Check your oil level. I think the drain back valves go bad to, like before it's time for an oil change. The 300 in my 93 has done that on and off forever and it seems like it's a combination of oil weight/condition, temp and the oil filter. Is it just telling you it's time to pull the dipstick or ch...

Re: Degreeing a Cam

Schneider cams have 2 degrees advance ground in. If you look at your cam card below the LSA it will state the intake centerline as 110. So if you degree it with an intake centerline @ 108, it will have 4 degrees instead of 2. Like said above I'd use centerline method first and see how close it is to...
