[QUOTE="Revvingchevy, post: 24237, member: 8246"] I think my gasket is both exhaust games heating the coolant? And some burimg off in one or two cylinders. Because I had a little white smoke at idle, but not really noticeable while driving down the road so maybe a smaller leak into one or two cylinders. I imagine the exhaust heat would expand it and it has to go somewhere so it finds its way into a combustion chamber or two. I was able to limp it home when it went bad (20 miles from home) and it would start to overheat when going uphill. I used Rislone heavy duty. It doesn't require any coolant drain. Just dump it in, top up the reservoir then idle until it gets to operating temperature. Then they say shut it off let it cool overnight. Then the next morning start it and idle it at 1800 for 20 minutes then shut it off again I followed those instructions (changed oil immediately after) then drove it 500 miles so far no issues, but driving it gently as in not flooring it. Edit - it has around 135000 miles Thanks Sounds like I need a real Felpro kit [/QUOTE]
