When the engine is cold it ticks for a for minutes until it gets warmed up then it stops and runs great. Any idea on whats going on? Thanks

Hi there,

You engine is fitted with hydraulic valve lifters one is faulty and is bleeding down, the tick is excessive valve clearance, while the lifter pumps up with oil when the engine is running, you will need to get it replaced, it is good practice to replace all the lifters if one is faulty, you can try doing an engine flush and changing the oil as this sometimes flushes out any carbon build up that may be fouling the lifter valving.
