Installed a new cam yesterday. Ran it for 20 mins at 2,500 rpm and then took it for a gentle run out for about an hour.

Driving to work this morning and noticed that there is a top end noise there like a tappet noise.

What could it be. Would it take a few hundered miles for the cam and followers to bed in properly?

Hope someone can help.

Cheers

still trying with mine!

been nearly 200! but got a fuel leak now.... ARSE!

cars off road for a while!

 

Where it leaking James?

 

all torqued up proper? squeezed all oil from tappets? new cam and tappets not old tappets/new cam etc?

 

might be wrong, but mines just started makin a similar noise and its the cam belt tensioner thats makin it??? worth a look if yove put a new cam in??

 

cud be ur tappets m8, either one is fooked or its just needs to build up pressure again...give it a few days and see how you get on...i had the same problem but cured within 2 days

I'll have a look at the tensioner and let you know. Seems to be coming from under the rocker cover though. Its is a brand new cam and tappets. Plenty of oil there n all. I'll give it a couple of hunderd miles and see if it gets any better. If not they'll be going back.

poor oil pump, low oil pressure. Did you change all the gaskets on the top end, e.g. cam seal, maybe try re-lapping the valves etc... all cvh's are noisey, my sounds loud but im using double valve springs and anti-pump lifters.

also you need to change the tappet\lifters at the same time when changing the cam otherwise the tappets will wear funnny and vice versa with the cam.

Ive known people just change the tappets on an old cam and within 20 miles there noisy again becase they've warn to the old cam!
