forgot about this should there be oil going to the turbo at all times. because i noticed that there is only oil flowing to the turbo when acceleration is added. no oil flowing at an idle. is this normal.

There should always be oil flow, but volume will increase when RPM's are added.

Cool - glad you found a better H1C price, Ryan!

We're about a half-hour north of Dallas... soon to be in our new shop.

You should check the oil pressure at idle & rated RPM with a real gauge (can be a cheap one threaded into the filter head's pressure port) to make sure - turbo's gonna last a lot longer with oil through the thrust & sleeve bearings.

Of course, since the CTD's internal lubrication system models as a fixed orifice, oil pressure & flow rate necessarily rise proportionally with pump RPM (gear driven off the crank).

That's your problem right there Ryan!

12 valves will run on darn near everything, but gas is a no-no...

























Seriously, though - probably not an issue... plenty of oil through the turbo with RPM (thus load & heat), and the residual oil remaining in the CHRA at idle should keep the bronze bearings healthy.

hmmm, at idle mine flows a solid stream out the oil line, you have to have oil flowing through the turbo all the time because it is oil cooled aswell as lubed by the oil I am betting that the line is collapsed internally and it should be replaced or you will trash the new turbo
