My rangers repairs in the last year. Used vehicle with 230,000km -altenator -battery -clutch petal (peral bent mechanic didn't know why that happened) -Slave cylinder -clutch (mechanic said the clutch wasn't the right part and the teeth had been matched up) My clutch still has to be bleed weekly, there's a speak coming from the tranmission area and when my truck runs for a while the oil pressure gauge flicks like crazy but only to the low part of the gauge. Please help
