no noise at all i have just tad bit of smoke when i first start it ,, thats because of maybe carb flooding or maybe valve seats ,, after i get it started ,,it goes away ,, now i am worried about the oil pressure after it gets hot i have below 20 my gauge start at maybe 10 small line then you see 20 lbs ,, i do have a HV oil pump that i am going to change along with new oil pan and get rid of the one that is on there now with a 2" piece added to sump i am going to check pickup also too and make sure its close to bottom ( what 3/4 to 1" up ) ,, i thought i could just change bearings ,, a buddy said it would be easy ,, pull all belts , pull plugs do rods first 1 at a time , then loosen all mains a little then them 1 at at ime by turning the motor said they should just come out ,,, now that being said after i look at them maybe they dont need it ,,,,,


thats why i am asking you guys

not valve seat but valve seals /valve guides . you do not want the pickup 1 inch from bottom of pan 3/8 1/2 max .... your engine at idle and could be 10 pounds it fine go back read what i posted if you do not under comprehend what i posted ... ask me . did you change the oil ? did you change the oil filter. did you check the oil psi with another gauge ? the engine could be loose many times they get set up this way . i would take engine out mic crank check out housing bores on mains /rods . check you valve seals move up to a better seal or fix,s guids so a rering or drive it like it is many years ago i seen a 327 that had under 10 pounds at idle .cold never came apart ran fine was that way i knew of for years

thanks pat .. i am going to tar into this weekend and see whats going on ,, the gauge i am using is from equus i would hate to get another gauge ,, i bought 6 from them ,,, ok what oil do you recommended knowing what you and oil filter ,, the reason i am so concerned is i spent 2k on my 235 motor in the biscayne i had i know i shouldn't have but it was all original when i sold it , anyway what oil and what filter ,, i might by another gauge just to check ,, it is a mech gauge also

thanks for the info i'll give it a shot
