My 2000 Frontier V6 4WD overheated on me with no warning now it is blowing tons of moisture out of the tailpipe, running very rough but there is no water in the oil so im guessing that i didnt crack the cylinder walls. I think it may be a blown intake manifold gasket because there is moisture in the head covers. Any suggestions would be appreciated.

I would say you have a blown head gasket. I wouldn't be driving it till I got that squared away.

Thanks Jagnorb

Thanks for the info Jagnorb, i am not driving it i am acutally in the process of taking it apart, while i have it apart im also planning on replacing the timing belt, waterpump and possibly the intake manifold gasket.

Yeah, that's a head gasket. You're gonna have to replace all gaskets getting to it. Intake, exhaust, etc. I'd do both head gaskets as well as have the heads checked out at a machine shop. Reseal the t-stat housing where it meets the block.

Yeah, I agree with them, head gasket. But just for a little laugh, one time my buddie had a P.O.S. Pontiac sun fire. It was doing the same thing as your truck. I put the radiator leak stop in the coolant. And believe it or not, It sealed up the head gasket and drove as good as it was before it blew! I might add he traded it in asap on a...Ford ranger I think. Hahahaha I still cant believe that fixed it!

The head or heads might be warped which will need machined. You could have a crack in an exhaust port. Before you take it apart, I would pressure test the cooling system using dye and try to pin point the problem area.

That's a good idea on the dye.

Block Seal By Moroso, And Steel Seal And 2 Very Good Products I Would Always Try First....blown Headgasket Into Combustion Camber = Misfire For That Cylinder(pull Plug And Look Or Codes) And It Then Goes Out Tail Pipe. If You Have Already Pulled Apart Now Would Be A Great Time For A Valve Job, Seals And Springs. Just Let Them Know To Check Deck Surface If You Dont Have A Straight Edge. Inspect The Gasket Around Affected Cylinder/s For Blown Gasket, Cracks Are Very Rare
