K Series - Noisy Tapets
Posted 22 March 2014 - 11:00 AM
Has anybody on here had this issue before and is it true that it's not going to give me bigger issues later on if I don't get it sorted?
As always, any feedback much appreciated :-)

A few thoughts, if you give it a real good thrashing after getting it warm it sometimes solves this issue. Failing that i think you can find the culprit by removing the cam cover and seeing which tappets you can compress. I doubt it will be more than one or two.
I have never tried this. It might be worth an email to DVA or KiwiRog to ask for the correct method of checking them. It should just be a case of changing the dodgy one / ones.
Edit, a few more thoughts. Hydraulic tappets will drain down if left for an extended period. The oil is fed via the oilways between the cam ladder and the head top. if you put too much / the wrong sealant on this will cause a problem by blocking some or all of the oilways.
You need to use the correct small amount of sealant. The correct sealant is disolvable by oil when not between mating surfaces. Im not saying its been done wrong but it could be the problem if they are know good tappets.

Are you sure its tappets? The VVC can be a rattly old bugger of a unit but its not particularly detrimental to it. Could just be the VVC which will rattle a tad about 5k after its been fully rebuilt.

I dont think Andys is a VVC? IIRC. You are right though some VVC,s are noisy. Some are not. Gregs for example is one of the quietest i have heard and its done 80K.

Thanks for the feedback.
As far as the engine is concerned it was sorted by Gav at Unit 4 (Fitted new unit and changed head gasket for later type). I have heard good things about his work and along with his Lotus background I feel that he would have done a top job. However, if some sealant has found its way into one of the oil capillaries then it makes sense that it would result in an oil starved tappet which i guess could be an issue later on in the engines life.
martin is right...my engine is a standard K-Series and not a VVC.

I doubt Gav has done it wrong. I would get him to check the tappets though
