ok well basically i let my buddy take a look under the hood of my '90 teg ls non-vtec to try and see if he could find out where i was leaking oil, well he thought it was coming from the valve cover seal so he tried tightening one of the screws that bolts in the valve cover but he broke the head of the bolt right off so now it looks like its stuck in there good..so i was wondering if this is a big deal at all and if i have to change iot how shoudl i go about getting it outt??? , alright thanks everyonee
