i'm a mechanic and have a problem with my gf's truck orginaly had a prob loosing coolant slowly so i pressurechecked and no sign of leaks then the truck truck started surging as the guage jumped around and the connecter for the temp senser was broke replaced and all was well for bout 3 days then a heater hose quickdisconnect broke so i repaired it pressure tested again and no sign of leak the today the guage started jumpin around again but intermittently i drove it and it did nothin, and the gf said she smelt coolant at one point, i did not smell or see anysign of coolant but...pressure checked any way and to no surprise no leaks. i hooked up the pressure tester and did not apply pressure but cranked the truck up and allowed to idke for 15 min or so and pressure increased to 2-3 psi, as i rev'd the truck i noticed the guage on my tester was drop 1 psi or so and it would smoke just alittle (white smoke) did not smell like antifreeze on the exhaust nor did it taste like it. i was wondering could the headgasket be blown and only be sucking in coolant on the intake stroke?
truck has 164K on it oil changed done regularly tune up done at 160K thats the only recent work under hood that been done, under the truck was wheelbearing,tie rod and tires. and fuel pump was installed last winter
i read somewhere that these intakes dont have coolant passages in them but i'm not 100% sure
