Rocker arm noise

[Josh'83]

I just finished installing a new cam,hydraulic lifters, intake, carb on my 83 302. I filled it with 10W30 synthetic. The engine noise(sounds like rockers) is deafening! I'm wondering if it is due to the oil weight or the fact it is synthetic. I have talked to a couple of engine guys who think it is the fact that synthetic is so much thinner. Anybody want to weigh in?

Hi Josh
I have never heard of an engine making more noise by changing the oil. Different viscosity or not. You must have a mechanical issue rather then the oil type or viscosity.

u sure u put oil back in? lol

Not sure what to look for if it is mechanical. I'm going to pull a valve cover this afternoon to see what I can see. I knoe the adjustments were made according to spec. I have read a lot lately about the fact that synthetics perform differently. Better or not is yet to be determined, I guess.

thin oil can lead to valvetrain noise, but 10w30 is not that thin. Pull your valve covers and go over rocker arm adjustment it should be easy to check since you the engine is carbed.

yeah, gonna do that around 3 today. When I get out of school. Planning on taking it to Carlisle in June. Hope I can get it finished.
