Fresh built 4.6. 20 minute breakin with in 40 minutes the oil pressure dropped to 11 psi. At idle.The stroker kit was bought from a well respected jeepstroker man. Engine built by a well established race engine builder. The crank that was sent was so undersized that different size rod bearings needed to be used and still ended up with a .0022/.0023 clearance. The mains that were sent was used but was left with a .0027/.0028 clearance. Melling 81 oil pump.
I broke it in with 10w30 as reccomended. The builder gave me some brad pen 10w40 but losses pressure at hot idle still. I really believe im losing pressure from the bearings. Were else?
I didnt have an oil pressure drop b4 the build. 6k is alot of money for large clearances and oil pressure drops.
Thanks
