it sound like it is coming from head

help with ideas

Sounds something like a pump on it's way out. Could just be a belt or cams.

That vibration noise?
Iff so...You changed the timing belt? You have tightened the belt too much.

Anyhow...the entire valvetrain is loud....tappets or oil pressure too low...

This

But also check your alternator belt, is it holding voltage fine? Could be alternator belt or bearing causing the squealing noise.

i am think on noise at 0.03
belt was changed cca 4.000km back
tappets have 15.000km
oil presure looks ok on gauge
at idle is on 2 bar, and when i rev it goes up

altenator belt on this film was not on

Dosin't sound too healthy i'm afraid...
Pistons to bore clearance?...was engine cold?...considering the fact that you had allready an bearing failure.....remove the sump and check those....

put alot thicker oil in and see does it quite down, sounds like a small end almost. is it only when warm ?

[stocious]

because, high vacum when revs drop, and oil pressure dropping at same time

i have mobil 5-50 in, have change it 300km back
that noise was there before, and it is always same ( done 500km atleast )
cant remeber now, but i think it is also when cold

whole botom end is new, didnt reuse the old parts, just head is same

what spark plugs do you have?if you have F5DPOR,try to pull it off and see and cracks on the white ceramic insulator part.I had that noise
on my motor and i just first realized that my lifters were dried out.

i use 10/60 castrol is expensive but its well worth it. when you say whole bottom end new, do you mean crank and rods too ? i hope its only someting small. but id still but it does sound like a issue !! isnt 5/50 a bit thin for these old engines ?

dont know for oil, my friend uses it and he is happy

yes, new bearings and rodas, diferent crank that was checked and grinded, diferent block oil pump ...

will check sparks ( i have f5dpor yes )
my first guess was also lifters, but people say that they are not, and they are almost new

ok i hope its not anything major i really do, maybe try put your old lifters back in and see then, and you can recheck belt tension at the same time, someone will chime in soon with some good news for you i hope
