best engine oil??
Discussion
I put magnetec in mine.
They all sound tappety but you need to set the valve clearances every 6 months... even so, I've never managed to get it absolutely quiet.

Edited to add: in my experience the oil only has an effect on the tappety sound of an engine if they have a hydraulic valve system. Presumably yours is a 2.9 efi engine which did not have hydraulic valves until the S3c cat equiped car which does.

I think you'll find that the S3C doesn't have hydraulic valves. All V6 engines have manually adjusted tappets it is only the V8 engines that have hydraulic valves.

I don't think thats right. What you're saying is that Ford changed the design of the engine to the extent of fitting different valve gear when they added cats. The 2.9 had different cylinder head design to the 2.8, maybe this what you're thinking of.

any one wanna answer original question please???
Nothing personal but things do tend to go O/T on here sometimes, come on chaps any more ideas for oil in the granny lump
I would have thought any decent 'branded' 10-40 through to 20-50 would see it right, the rest is personal preference. Ford lumps can be pretty tough old girls.

I've just checked in my granada haynes manual and it does say that ford introduced hydraulic valves at the same time that they introduced the cats. No idea why they did it but they did. I haven't got one so can't absolutely guarentee that this is fact but there are a few people on here that believe their cars to have hydraulic tappets... www.pistonheads.com/gassing/topic.asp?t=7653&f=11&h=0&hw=hydraulic+valve

...odd though I grant you.
funbobby, I did answer your original question. It's not like we just sit here all day waiting to be asked questions like a bloody RAC helpline, we're just chatting about our cars mate... pull up a chair, relax

Well, slap me round the face with a fish supper - proves you can always learn something new. I had a S3C and never knew it had hydraulic lifters. I'm amazed that they changed the heads that much for the cat versions.
Even my usual infallable source of info - the S bible states "on the 2.8 and 2.9 litre V6 engines, these (valve clearances) need to be adjusted every 6000 miles... The V8 engines use hydraulic lifters and do not need any adjustment".
Thanks for the clarification.

Hmmm let us be very careful here. Ford told me that they never supplied the 2.9 engine with the type 9 box... but TVR certainly did that. The cat system on the TVR is not Ford's but a hybrid. TVR just stick the cat in the manifold and connect the lambda sensor.
Now I think that the lambda sensor connection was in the ECU way before the need to fit them so I think TVR may have just ordered plain 2.9 engines and catted them themselves. Also bear in mind that in 1993 V6 S sales were virtually dead and I expect there may be plaenty of old 2.9 engines going cheap that Ford couldn't use that TVR could. I have never seen any TVR reference to hydraulic tappets but plenty to adjusting the clearances.
Yes the Haynes manual may be right for the Granada but that does not necessarily means that TVR followed that path everytime. The only way to find out is to strip the engines and look. Ted's got a S4 so why don't we strip that one at a meet or something?
At a guess I reckon that TVR simply continued to buy the old engine until they started using the new ones.
NOthing surprises me about these cars these days...

otherwise how did they manage to up the torque figure from the pre-cat 2.9 by 20lbft whilst fitting a catalyst exhaust system?
Bigger/better exhaust manifold. Exhaust manifolds can add torque or change the curve by modifying things like back pressure. The cat does modify this quite well. Hydraulic lifters don't add power.

The mech at the ford garage that did the timing for me said they used to get lots of post 91 granadas coming in with hydraulic tappets where people had adjusted them without knowing they were hydraulic. He said they still had the adjuster nuts.

!! From what I've read over the years regarding slick 50 I'd be somewhat reluctant to buy a car that had slick 50 added to the engine oil. Is this me being too reactionary or is there really something in the views that this sort of stuff can block oil passageways? I think, at best, it would seem to be a waste of money.
