[EVO X] Check oil pressure when cranking

Hi,

anyone a good idea how to check if oil pressure is there (after engine build) ?

I do not want to install a gauge, I do not see an oil light on the dash when turn ignition on....

Thanks for any help.

Rico

is the car running ok ? just above oil filter there a bung u can tap into that for a gauge if u wanted too.
or remove the the coil connectors and crank it over before u u do your first start. that will get the oil around the engine.

As far a I recall my engine builder used to turn the engine over by hand until oil appeared in the top of the head. But he was a stickler for that kind of thing.

Thanks, I think it is stupid that it does not show "low oil pressure" light when engine is not running. In the good old days you can crank until the light went off so you know oil pressure is ok and you can start.
I read that sometimes the oil pump does not pump the oil because of air in the pump.

I spin the the oil pump with an electric drill until I see oil
appearing around the cams etc.
Decent battery drill will also do it.
You will feel a big difference in resistance once the oil is picked up.
Turning by hand is never going to achieve this.

Your last comment (in bold above) - I've seen it done on Evos (but not on a X). Wasn't always easy, but got there in the end. Obviously the point of it is to avoid the perceived risk of causing bearing damage when spinning the engine over on the starter motor, but I've no idea if this risk is even real let alone significant?

I always turn the pump with an electric drill on older evos, after major engine work.... but on the X the pump is run by a chain off the crank so without removing the front cover and sump it can not be done..

Having said that, investing in a small electric oil pump would give you the option of pre lubing the whole engine before starting up... for first start at least..

If you used assembly lube then the risk is minimal or non existent.. Talking about first start after engine assembly of course..

I'd bet it wasn't easy as it can take time with a drill .
But some people just love hardship

Thinking about it, the situations I recall may well have been where dry sump systems had been fitted and therefore not receptive to using a power tool on the normal oil pump shaft. It seemed to work - eventually!

I will measure the oil pressure sensor with a multimeter if I get oil pressure.
(hope the sensor is good)
