Intake or head gasket problem? help!
hello everyone,
I own a 1999, ranger with the 4.0, and when the outside temp is below 30 and I START the truck for the first time in thee day the engine will crank a little longer then normal start stummble a little and die, usally on the restart it will start and idle perfect. Now that it is warm it starts perfect. I have replaced, iac, iat, ect, spark plugs and wires, fuel filter. I also have a coolant leak that I couldnt explaine untile today. I decided to look up through the wheel well and see if I could see any sign of coolant and there was old burnt coolant all over the side on both side of the engine comeing from the heads or something, I couldnt tell exactly.
I was told that the hard cold start problem could be intake gaskets. If it was the LOWER intake gasket could it be leaking coolant on both sides of the block explaining the hard start and coolant loss. Maybe head gasket causing both? There is no coolant in oil or visa versa and like I Mentioned the engine runs excelent just leaks coolant and starts hard when it is cold out, it uses no oil at all. I wanted to get some input before I went to a mechanic. thanks,
mike

Hey Mike!! They've gatta be seperate issues IMO. The coolant's leaking to the outside of the engine. If it's responsible for the hard starts, it would have to be ingressing into the internals somewhere and contaminating something like the plugs, but that would be a problem in all weather. Try pressurizing the cooling system to what the rad cap says is it's relief pressure. Use a hand or bicycle pump through overflow tube. You'll have to get an old rad cap and cut off the inner portion that act as the Press. releif valve. With the engine cold and off, spray the rad and everything else with soapy water and look for the bubbles. The leak could be comming from the front of the engine and blowing back onto the block. A pin hole leak in the rad can spray such a tiny mist that you'd miss it.
The hard starts could be something like the valves sticking open or a lifter sticking up when she's cold. Hard to say, but the fact that she starts right up and runs just fine right after is a headscratcher otherwise.
Lots of threads on trackin down vaccum leaks around the intake manifold with propane. Try a search
Keep us posted mate!!

i wonder if one of the freeze plugs arent bad or the block maybe, if its a head gasket USUALLY not all the time though it will either white smoke with lots of water in the exhaust or turn you oil into something that looks like a milkshake. we just rebuilt a forklift engine at work that was thought to be the head gasket (it white smoked and milk shake oil) well after redoing the top of the engine it ran great for a day. then back to smoking with lots more water in the oil.. tore the whole thing down found a crack in pistion sleeve right along the water jacket. so dont always asume head gaskets lol.
edit* also had a freeze plug go out on my lincoln once. it was one in the head behind the power stearing pump, it sprayed water all over the front of the engine took a while to trace down. darn thing had a small pin hole.
