If all good ie not injector and compression good it has to be a little end or something deeper in, cant think what else it could be though..

Thanks HUE166

Definitely a internal engine noise, some of the rattling heard is the gear stick

Easy way to check injectors is to drive the car and just turn ignition off. Or get it high in the rev range and back off. Either way your injectors wont be working. I third a manifold leak.

had a bit of a look see this evening,

injectors leak off test, runs with the comp hooked up

injectors out

endoskop showed lovley looking pistons. bores. spray pattern and valves, expected a lot worse with this milage

Valve cover off

this could be the answer or at least one of them

this little clip shows exhaust valve Nr. 3
cam lob and follower. hard facing worn off, follower out of round


nice evening to all of you, thanks for all your inputs

Thats more common on all types of motors than you think,cam repairs weld them up and regrind them. Pat

thanks Pat not wrong,

i reckon it is all down to servicing and using the right grades of lube

the owner of a engine and gearbox reckon workshop i know once said

if vehicle owner would half the miles between services and use the correct grade and quality of oil
transfer case included

it would but him out of buisiness

wish you all a plesant x-mas break
