Technical engine problem

[rocco b]

Hi

just wondering if anyone can help me?
i own a fiat tipo 2.0 16v turbo
i have recently started to have low oil pressure and a knocking noise
under load when revving high.

when cold the oil pressure is good 4.5 bar on idle. when at 70degrees on idle
the oil pressure drops to 2bar

when the engine is at the normal running temp (90)degrees on idle the pressure drops to 1.5bar

when revving the engine from 3000rpm to 6500rpm the oil pressure does not go over 2.5 bar

the best way to describe the noise to you is when you build the revs in the same gear to around 3500rpm - 4000rpm and then accelerate you will hear the rattle.

I also have a problem with turbo it does not over boost. When in a high gear and you accelerate hard it doesn't exceed 10psi - a friend of mine said this isn't normal and that it should over boost.

can any one help i'm very concerned!!:bang:

the oil i'm running at the moment is Selenia racing 10/60

Them oil pressures aren't terrible, have you checked the state of your cams? If they wear they circulate metal filings and ruin the bottom end.

I would'nt drive it as you don't want to ruin the crank.
