1998 Ford Ranger 4.0L Head Gasket Issue?

I think I have a leaking head gasket by the number 3 cylinder (passanger rear). It throws a p0303 misfire code from time to time. If I change out the plug it will go a couple months before throwing it again. The old plug does have a slightly sweet coolant smell also. The truck uses a small amount of coolant each month as well (%26lt; 1qt) but not signs of leakage under the truck. There is no sign of coolant in the oil when I change it and I can't see any signs of oil in the coolant but not postive on how to tell for sure. The truck does not run hot. The exhaust does not show excessive smoking either but does have the slightly sweet coolant smell. Is this a small leak in the head gasket? Are there other causes I should look into? If the head gasket, should I try one of the head gasket sealers out there first and, if so, any recommendations? If replacing is my only option, any ideas on what ballpark cost I should expect in NE? Thanks for advance for any help.1998 Ford Ranger 4.0L Head Gasket Issue?The coolant smell found on the sparkplug, and the other facts that you've mention, tells us that there was really a leak between cylinder head and cylinder block. Water around the base of the sparkplug, can cause it to become busted thus misfire occures. In this situation sealer cannot solve the problem. The only way is to make top overhaul of your engine, to find out wharpage, this either at cylinder head or at cylinder block, The gasket is not reusable.

About the cost your technician can give you a detail, this for labor and parts1998 Ford Ranger 4.0L Head Gasket Issue?For that small a leak, I would try the sealer first.1998 Ford Ranger 4.0L Head Gasket Issue?Head gasket does sound like the problem. You could have a miniscule leak going to the cylinder. That could burn the coolant and foul the plug. I would get a head gasket se that come with all the gaskets from the heads, up. Intake and exhaust manifold gaskets could also be leaking, so get the whole set. Deposits in the water jackets near the cylinder can also create scaling and pitting that can eat pin holes through the block into the cylinder. Good Luck.
