low oil pressure charged b16a

[yeehau86]

how about when high rev?what is the pressure?

in ur case, check your bearing clearance........hondatech ppl told that bearing clearance do affect the pressure... +-0.5 bar is very low that is harmful already... since ppl said,when pressure less then 1 bar the engine oil lights will going out already.....

mine is iddle 1 bar +-,crusing 2 bar plus,when start rev, the pressure going up a bit then drop...

any else can help?

regarding that buble..how about engine oil viscosity??does it deteriorate faster than usual??? perhaps too much piston ring gap?

or could be some pressure drop due to source of turbo oil feed??)

finally issue has been solved, there was a bolt missing in the crankshaft that the owner changed which he bought elsewhere. didn't know that is the culprit

how big was the oil cooler???use any oem from evo series i think already enough....if it was already from evo cooler then no worries...

it is small one... calsonic oil cooler that previously used as my ATF cooler....smaller then evo size

some ppl just asking me to remove and dun use oil cooler since daily drive and sometime drag.... no track session... what u think? but must use good oil la...

nope....peterj ur last post say that ur oil sensor pressure u tap in same place with ur oil feed to turbo right? all joint in same place...'Mivec oil pressure sensor locate at side side head mean in top...and its oil jurnal from blok to head also in 1 line'....have u test relocate the oil Pressure sensor to other place like in front of vtec head that have nut oil stopper for vtec oil line...:hmmmm:

i dont understand bro...

peterj...i've got an idea to test your oil pressure.... first rrmove the turbo oil feed line and close it(disconnect turbo oil inlet pipe).... then start your engine and check your oil pressure meter...try rev to see if there any different pressure than before....just dont run your engine too long to preserve the turbo that was running without oil.... if yes means u have to resize yourturbo oil feed line...if still ssme then i've noidea what to do anymore...

if like that cant it be oil pump failure? cause i now on the progress changing oil pump.. not yet done.. will see what happen after changed to type r oil pump
