hi all, after having the tappets and cam/belt changed on my f/reg rs, its started making a knocking noise witch sounds like the camshaft,, if the timing was out would it knock? im worried sick because my m8 who changed wont answer his phone now, and im worried to drive it to a garage to get it done propley,, the car was not! knocking untill the can/belt was changed!!. is it just the timing out? or is my engine nackered? thanks in advance. martin

was it new parts fitted and did you run the cam in, for around 20 mins at fast idle?

tappets are shit mate, check the timing is right before you start it up. Chances are you have crap lifters that are made cheap.

to late m8 ive all ready drove it about 40 miles, have i reacked it?. thanks

is it a kind of rattle mate? if it is could be that the timing is slightly advanced on the distributor which is a easy enough fix

hi m8, its a proper horible sort of tapping/knocking noise, to make it worse ive drove it about 30 miles. thanks again

did you fit just the tappets or a cam aswell, u say a cam belt but was it a cam kit, no point fitting new lifters without a cam as if the cam was warn then you prob just done the new lifters in.

hi, just new tappets and cam belt, not new cam shaft, thanks

is it running ok or on 3 cylinders?old cams and new tappets can go together as long as the cam is good and not showing signs of wear.if its worn it will tick from the moment its fired up and get worse.if your pal just fitted tappets then he wouldnt have had the cam out to check it.if its lunched a tappet then you will need to change the cam,tappet/s and oil and filter and cross your fingers the oil pump is ok.this happened to me last week and my engine was ok.i bought new tappets from an engine builder with 30 odd years experience who told me that if the cam is fine then you can use it with new tappets.if its worn it will destroy them.get a better mate to fix it.
