Title: engine woes
Post by: shepgti on 10 March 2009, 13:45

right my engine is making a really bad tapping noise now, educated guess would suggest the tappets (now what are they? where are they located? do they fail?  :undecided:)

all input welcome!

Is the oil pressure OK and is it topped up?

No flashing lights on the dash?

tappets are little hydraulic dampers that fit between the cam and tops of the valves, they have a tiny hole that allows oil to fill up to give a damping effect. when the they give up which isnt uncommon they give off a tapping sound. If it hasnt had a oil change do it and use a good quality oil and give it a good flush. They arent a major job but not a 5 min one either.

Certainly worth a try as its far cheaper than having to take the head off etc.


Oh didnt somebody sy you can replace tappets without taking head off and removing valves? :undecided:

I think you can, i was under the impression it was cam out but you dont need the head off. If it need them replaced its an excuse for a cam belt if it hasnt had one. You will need all 8 replaced though! Only a few quid each i would of thought!
