just baught my car /w this "freshly " built motor like a month ago.. supposedly:

Engine:
B18B 1.8L Non-Vtec Head
- Port and Polished
B20 Block
- Bored/Sleeved 84mm
- Sleeved by Golden Eagle
JE Pistons 8.0:1 and Piston Rings
Eagle Rods
Turbonetics T3/T4 Hybrid Turbocharger
Rev Hard Turbo Manifold
tuned on chrome @ 6 psi.

got a noise from motor within 3 days after purchasing car from testing to see if rev lmiter would kick it (rev'd it to 7.5krpm) barely went anywhere with car, thought it was a rod knock.. did valve adjustment, noise still there, then 2-3 weeks later took it to BSERIES and finally deteremined that it wasnt a rod knock, and might be Piston slapping wall due to error on person who machined it, or whoever built it just pieced it together and didnt know how to measure it. did a leak down test, resuls were bad. 2 of them did not hold pressure, turned out to be valve seals most likely, another had bad piston ring due to oil on sparkplug. planning to just drive it and baby it, wondering if i got the correct oil to use.. was running 10w30 fully synthetic, but now baught Valvoline Racing 20w50. dont know if its too thick but thats what i remember someone tellin me , to get thicker oil and just baby it.. so wondering if i got the correct oil, and if so is it safe to use w/o ruining my turbo seals or anything..
