Just changed the oil in me cossie and it sounds like a a fecking TANK not sure what was in it before as ive only had it a few weeks but it was perfect no tappeting AT ALL!
Goes to halford buys a 4L and a 1L bottle of Mobile 1 15w-50w, then to fords for a new filter. Changed oil started it up and after a few minutes the tappets start to sing!
So i thought it'll be alrite after a while............................................. .......
but its still tapping??

Wrong oil or what???

Mobil 1 is VERY thin these days, you need Mobil 1 "Motorsport" Its in a similar bottle just to add to the confusion

i use fuchs silkalene 5-40 race oil, people probably wont agree with my choice but it seems to be doing the job

Thats the thing who do you listen to on advice about oil?? Fords recommend 0w-40w! Trial and error could work out very expensive

Billabong

Ford (as in vehicle handbook), or your local dealership? 0w-40w is not the correct grade for a Cossie engine (unless it's been rebuilt and that's what the engine builder advises)

righthooker

they put 10/40 in mine any how now got silkoline s 10 50 off the oil man sound fine

In fords in bristol street the fella who serviced a friends car showed me a service booklet and it says that 0w-40w is to be used???
Maybe my tappets are are fucked,just funny that they were fine before i changed it Never had a problem with the mobile 1 in my last cossie

15/50 is fine for a standard Sapphire Cosworth. I used Carlube triple R 15/50 in mine.

If it was too thick - then I'd expect the tappets to rattle on start up and go quiet after a while.

You HAVE re-checked the oil level haven't you

Maybe (as it's a car you just bought) there was some additives in the old oil to quieten it? Wynns do one specifically for noisey hydraulic tappets.

TBH I have used 10/40,15/50 and 10/60 and they all sounded exactly the same , the only difference was oil pressure.

I used 10/60 in the end , that was in there for 15k miles with no probs

Yeah think i'll invest in some new tappets,like i said never had a prob with the 15-50 before.

oilman

The silent majority agrees with me!

What we don't know about oil isn't worth knowing, can we help?

ALWAYS!
