Hi there, engine internals specialists welcome

Anybody knows if an STi closed deck (with extra lubrication lines spraying under pistons) can run a std version MY00 oil pump ?

I was just wondering about this extra flow dump... won't this result in low pressure @ low rpm with a std pump ?

Cheers

Gerald

 

Yes to the first question, no to the second. The jets don't open until around 4bar (3.8bar on mine) so idle pressure remains the same.

 

Arent the pumps the same?, and only the very early STI's had closed deck blocks anyway. Most were open deck.

 

AFAIK the pumps are the same.

 

hypoluxa, thanks for this clarification.
I'm trying to locate the hi-pass valve from now

Stevie, no doubt: I'm talking about closed deck.
I can easily make the difference between open and closed : they're side by side on the table

By the way, anyone knows if all closed decks were attached to gearbox using 4 bolts, as std MY98 and previous ?

Bye for now

Do you mean the pressure relief valve? It opens at 5.5bar or thereabouts. With the oil squirters I don't reach that except for cold starts. Yes regarding the gearbox bolts.
