rebuilt b18b1 block. fresh hone from the machine shop, baked, cleaned, degreased. new rings/bearings/gaskets all the way around. motor started up fine but theres a major oil leak coming from the oil filter.


i used a cheapo advance-auto-parts filter and oil for the initial startup. had it idling till the radiator fan kicked on twice (2 cooling cylces). i went to change the oil/filter and noticed a puddle under the motor. further inspection lead me to believe it was the oil pressure sending unit. changed the oil and filter (oem honda) and started her back up again. i crawled under and hit everything with brake clean. to my astonishment i visibly watched oil start leaking from around the filter.


cliffs:
-newly rebuilt b18b1 block
-no oil cooler
-2 oil filters leaked on me immediately


whats the deal? i wont get a chance to look at it till tuesday because of school and work, but i've never had this happen before. no there was no old gasket there, yes i oiled the filter gasket before i put it on. why is it leaking?



edit:
also, my motor is dieseling (found that out after a bit of googling). should i try injector cleaner? i dont want to run seafoam on such a new bottom end. would it mess anything up?

sounds like you have some excessive blow by..... pushing the oil into intake tube? this car aint smoking at all?

Dumb question, but did you grease the oil filter gasket?

did you replace the large o-ring underneath the oil filter mount?

the oil filter threads onto a large nut (27mm socket?) and once you take that off, the base of where the filter threads onto comes off with an o-ring under that.

Anyone have the part number for said o-ring? Also, could ignition timing cause Dieseling? I have a tank full of regular. Should I run mid-grade or premium? I didn't think a stock ls required it...

no the car isn't smoking. wouldn't the pcv pick that up anyways?

Turns out it was the oil pressure switch. The block is cracked down the house. Jb weld is drying as I type this. Hopefully it'll stay.
