alawode Posted December 9, 2009 Share Posted December 9, 2009 Hi Guys,The picture below is for a 1991 Ch613 Mack that i'm planning on buying. The problem is that on inspecting the engine i saw that there was an oil leak near the top of the engine near the back [the side that nearly touches the dashboard/cabin]. The truck has not been moved for awhile so i also spotted some oil stains on the floor directly under the leak.I was wondering if this discovery was a big enough red flag not to buy the truck, or is it something to expect due to its age? Please advise, your input is highly appreciated!!N.B> the leak comes between where the top of the engine can be removed [near the back] Quote Link to comment Share on other sites More sharing options...
Freightrain Posted December 9, 2009 Share Posted December 9, 2009 Can you see if it's just a valve cover or worse(head gasket)? I assume you haven't started it to see if it "leaks" while running.From your description("where the top of the engine can be removed"), does that mean the head gasket area(between block and head)?

I did start it, but i didn't observe a leak when it was running Quote Link to comment Share on other sites More sharing options...

MACKS Posted December 17, 2009 Share Posted December 17, 2009 Your talking about an engine that's nineteen years old,I wouldn't let a minor oil leak stop me from buying the truck,if it was or is a bad leak that needs to be fixed than maybe you can get the owner to ether fix it first or deduct the cost of the repair from the selling price.Good Luck Quote Link to comment Share on other sites More sharing options...
