Thats the second time someone has said that will
Have to get it looked at...would the tapping from the manifold
increase with the revs.
Should of stayed with the m20

check a load of daft things Barry like are the spark plugs in tight, is the exhaust manifold tight to the head, is the lambda sensor in tight?
Where does it sound like the tapping is coming from, top of the engine, front etc etc

well its hard really to hear where its coming from so heres a little video so just incase you might know from sound in the differents, also is`nt the sound of the engine suspose to dye when you take of the oil cap off and spit out oil.

I dont think it sounds too bad, possibly a sticking hydraulic tappet. you could try some engine flush, get the engine nice and hot and change the oil and filter. then thrash it, the m50s are bomb proof

You must have a leak somewhere, removing the cap should result in a noticeable change in rpm.
Thanks will i`ll look into the air leak, i just carnt get my head around using diesel oil but if it works i`ll try it,

sorry to ask this but can anyone else back up what Willnz is saying.

I'd probably do about 200 miles and I wouldn't rev the fanny off it, but it's probably perfectly safe.
If you're brave, parafin & gear oil & leave to tick over for 20 mins would clean her out

Thanks for that buddy, great read
He talks about doing it to a vvti and as i dont know how much oil one of them takes
Would i do the same 3ltr mix.
We have diesel trucks at work so i can get my hands on loads of them both.
tonight at work i`v got myself 10ltr of 10/40 diesel oil which we use in our trucks from volvo and about the same in transmisson oil which is the same thing isn`t, will these both be ok to use let me know as i`m going to give it a try sometime today.
what i need to know is how much to use...???? the same as if i was butting fresh oil in.
