ADT168

hi everyone.
i have just got my fiesta rs on the road.
when you start it it tapps so i have bought a new set of hydraulic tappets.
i left them in oil for 1 hour. took them out the oil and fitted them. torqued them to 27 nm.
i put new oil in the engine 15/40 castrol magnatec. originaly it had 5/40 in the car.
started it let it run. still tapping. took it for a drive still tapping.
i have removed the tappets now and left them in 5/40 oil all night till tommorow.
what do you think?
if it still tapps then i dont know what i can do next.
the new tappets cost me £50
any info appreciated
thanks regards ashley

where the tapping coming from cos it could b the cam or possable the bottom end.
how loud is the tapping aswell?

I would be using a 5W40 to start with, they can take a little while to settle fully, somethimes up to 10 miles you can hear them faintly still.

i drove the car 30 mile with 15/40 oil.
i have put 5/40 in the car now. ill try and fit the tappets tommorow after they have socked inoil all night. hopefully it well be quiter. if not then

try pushing the tappets shut in a vice, wind them in & out a few times, this can help, did you check the bottom of the old tappets, if there concaved & worn then it will probably need a new cam. i normally run cvh's on 10/40

ADT168

the bottom of the old tappets looked. just a circle on the bottom of it.
its just that they were tapping so i thought i would replae them.
wouldn't that push the oil out of them putting them in a vise

I would always advise fitting a cam and followers together. Its prob the cam thats fooked as well.

ADT168

could i take my cam to a engineering place?
or do i need a new one?
are they hard to remove?

Matt Evans

Throw your old one in the bin, yeah, its an easy enough job if you know your way round a tool box!

Be an ideal time to change cambelt & tensioner if you dont know when they were last done.

ADT168

the cambelt and tensioner are good.
i live in essex. where would be the best place to get a camshaft?
the rest of the engine is completely standard.
would you recomend getting a kent cam or a standard cam.
thanks regards ashley.

putting them in a vice will push the oil out, do that then let them soak for a while. Is it timed up ok?

ADT168

yea its timed up ok.

ADT168

i have got my fiesta booked in tomorow at a garage for them to check the oil pressure.
i got some prices on the camshafts.
ford camshaft: £191
rockers :£13 each
kent camshaft from burton: £160
rockers:£99 a set

smerth54

yea ide update the cam whilst youve got it out plus its cheaper
