Hi. I hope to get some advice on my rebuilt neo oil pressure and a small oil leak..
After a catastrophic end to my engine months ago where timing belt idler came loose and fell off the head and some pistons got minced.
Anyways new head and rebuilt engine later..
First I want to ask if my oil pressure seems right. (New main bearings!!) Idle cold is 4.0Bar, idle hot is 3.5Bar, 4000Rpm goes up to maybe 4.5Bar. I have not hit high revs yet.. won't for a while! I'm using Repco 10w40 fully synthetic oil
Dash gauge being used! Not a proper gauge! So it won't be fully accurate!
Onto my little issue,
I am having a small oil leak from front of engine and cannot identify where it's coming from. It seems to pool to the right (passenger side) of the oilpump
I've once already tried to fix this by taking the radi out and the main pulley off to inspect behind timing belt cover.. tightening oilpump a little more. Also adding some more gasket glue to the sump/oilpump thinking the leak was that..
I honestly say that the timing belt is dry, the crankshaft timing belt gear and under it is dry (main crank seal is not leaking.., if it was leaking I think the inside the timing belt covers would be soaked?)
I saw a bit of oil from the timing belt idler pulley. The metal shaft of the pulley which bolts to the engine.. I saw a bit of oil under it, where it touches the block.. I don't know if it is flowing from there or somehow got some residual oil from the build! You know!! Oiling the bolts, and seals.. maybe it is not leaking there! (Won't know until I take off the covers again)
Has anyone ever had oil leaking from the bolt that holds the timing belt idler pulley?
Other then that I am thinking the oilpump/sump join is not sealed 100% or something..
But seeing oil as high as the idler pulley makes me think elsewhere. It could be blowing around via the radiator fan.. / timing belt..
The cams are not leaking I'm 99% sure as it's bone dry that high!!
My dad keeps talking about blowby pressure being too high.. maybe making the oil seap.
Should I give it a week or two of driving and. See if this leak stops?
Sadly the photos were taken 2 days ago when I had the bits removed.. it's now all complete and my test drive last night.. when I returned home.. had leak still..
Thanks.,
The image here shows the corner where it drops oil. (Passenger side corner front of sump)
This photo shows the crank gear is dry? But the outside of the timing belt cover (right of pump is wet)
This photo shows the water pump is dry.. (it is dirty. Didn't do such a good job cleaning inside the gap there!) so I am sure no oil is leaking from camshafts..
