    Default 306 Hydraulic Lifters

    Is it possible to adjust the hydraulic lifters in a 306 1.8 litre engine or do they need to be replaced? I'm getting a light tapping noise, particularly when the car is at normal operating temperature..noticeable when engine on over run..not so much during acceleration. Have had the timing belt, tensioner and water pump replaced. Car has done 162K's. I've also tried the old trick of flushing the engine with Auto Transmission Fluid. It's so clean in there you can hardly see the oil on the dip stick. I'm thinking the culprits must be the lifters. Any help would be greatly appreciated.

    What oil is the engine, did you change filters twice?

    It's more likely got a bent valve. However, you said that you looked inside. What condition are the cam lobes in? ie are there any flat spots or signs of wear? I've seen this before. Idiot mechanics replace the oem lifters with inferior after market items and the problem still exists. Just be careful and do your homework, as an OEM lifter was approx. $60 each last time I checked.

    Light tapping on overrun but not under load classic diagnosis is small end wear, but not usually at 162k unless badly sludged up. Is it obviously coming from the valve gear?

    I have a lifter that rattles for a while if I drive straight off after start up. If I start the car from cold and let it idle 3 - 4 minutes before driving off the lifter pumps itself up (bleeds itself) and then there is no rattle.

    Try it.

    Thanks for that info. I did use auto trans fluid in oil but didn't change filter twice. I refilled with semi synthetic 10/40 and new filter. We haven't looked at the camshaft lobes or lifters yet. Next port of call. It's weird..you can sit there reving the motor in neutral..no noise. It doesn't have that typical lifter noise when cold either. It must be something happening when engine is under light load..like going slowly in say second gear..no throttle...apply a bit of throttle..noise comes in but seems to disappear as revs rise. You cant hear it as cruising speed and engine is strong. Now I'm reading about chain driven oil pumps. Do the chains ever rattle on these? Still think it's coming from the top of the engine. Solution? Crank up the Eurovox Cassette Player..cant hear a thing!
