okay, swapped a 1990 Ls (b18a) into 1990 crx. there is something wrong with motor. When I originally bought motor there was water/oil in the oil pan i figured it was a busted head gasket. Replaced head gasket and resurfaced head........now when we ran it first time.... ran ok no problem just to see if everything was ok and it was. second try turned on let the motor warm but it started to overheat. I checked the oil and as soon as i took the dipstick out a white, milky like substance came out. Looks like water and oil mixed together...........Did a compression test and passed with flying colors.........did a leak down test theres a problem theres a leak on the cooling system somewhere and water is getting in the oil soemhow any suggestions?????????????????????

 

Check your new headgasket.

 

we have its new and i have to replace again but there is a leak somewher inside you can hear it when we did leak down test............i dont think its the head gasket

 

if its not the head gasket then you got a cracked water jacket.

 

pressure tested head.................passed..................yep it was a water jacket..........craked mixing with oil.......bad need new b18 i guess i have to start shopping.............thanks for the help guys
