High Andy,

Sounds like a lazy tappet to me, not uncommon on CVH especially if it's had infrequent oil changes or lots of short journeys. DON'T try to fix it with flushing oil or they'll all get clogged. Change oil and filter for good quality ones and get it nice and warm then go for a good long drive. If it don't quiet down they you'll need a new set:mad:

BV.

Thanks Gary,

I,ve just allowed myself to breath again :eek: :D

I,ll change the oil & filter tomorrow & run it up to temp slowly on tick over & see what happens , another gulp of air :D

To be totally honest, as the engine had a full service history etc when I bought it, I haven,t even changed the Oil stem seals,
Would this be a wise move ? it doesn,t have excessive smoke on start up.

cheers

Set!

Just try one at first ;) dont want to kill the budget :D

20/50 was favourite for everything a hundred years ago.Autodata says anything fom 5/30 to 20/40 depending on temp for that engine, I would say 20/40 if you can get it, if not get the thickest and add something like Wynns and I take it the oil pressure is ok.

And what Vern says makes sense.

Can be done with head on but not worth aggro in not smokey.

Naa leave well alone, it's a head off job and not worth it if it's clean. Should be good for a few 10k's before that needs doing.

The car I had was full dealer SH, had motorcraft parts and had been well looked after. Was a clean car actualy all round, but the second engine started using oil. I bought a Carlton and we traded the Sierra in against a BMW e30 325i Sport for my Bro ( think he just turned 21!!! ) AWSOME car ;)

Big Vern.......

Thanks for that :)
I,ll get some good quality oil with a good oil filter, I,ll get slightly thicker oil as Paul suggests,
As for going for a long drive.........I haven,t got my prop yet, maybe i,ll get Spud to push me for a few miles :D
I know the engine uses Hydraulic lifters but should I / can I still check any clearances...eg like checking tappets etc ?

Thanks TT, so if it is a Lazy/failed follower its nice to know its a fairly easy repair.

Paul, cheers, I,ll get as thick as I can get within the boundries of the oil spec,

Whilst I,m here talking of my engine...........
As i,m using an aftermarket air filter instead of the huge "frying pan", will this alter the tickover? as it seems to be running a little fast on tickover, I thought it was the automatic choke ( this is still plumbed in correctly as per original setup,)
Once it gets up to to temp it only drops the tickover down to about 1200 revs, in the haynes maual it suggest 900 - 1000 revs once warm

Thanks for your helps guys :cool:

cheers

You could probably replace all 8 tappets/followers in about half an hour

As for the tickover...... the auto choke is the most likly culprit, Pierburgs get a bad wrap as beeing crap carbs. the carb is fine but the auto-choke can be troublesome..




I think when I had my 1.8CVH I went through all 8 followers, an exhaust manifold, spring set, and 3 head gaskets ( 1 to rule out the head gasket, 1 to swap the springs and 1 to replace the snapped head bolt that occurred during replacing the springs... )

TT

Cheers TT,

I,m sat here reading the manual,

Also, thanks to forum member "Mark", I do have a spare Pierburg carb with all choke bits still attached, might be able to "Mix n Match" to solve the tickover problem.

I guess my new tyres will have to wait a little while longer :( :rolleyes: :D

cheers

It could well quieten down with use. I have a very slightly rattly tappet on my car, it is there when cold but goes quiet after a minute or two running.
It's not going to be a massively big deal to sort it, even if a couple of bits do need changing.
Best and all that.
Enoch

cheers Enoch,

Thats why I was a little concerned , as it gets louder the warmer the engine gets, rather than getting quieter etc,
so, I,m going to change the oil to a thicker viscosity ( spelling??) & new filter & see if that helps, if not then I,ll look at changing the offending parts.

cheers
andy
Ps... might still get my new tyres :D
