blueovalz Posted June 3, 2002 Share Posted June 3, 2002 Just when you thought you knew it all (how humbling is this that phrase!) I was awakened to an oil filter lesson. Purely by accident I was reminded that oil filters pass oil only in one direction. I knew of the anti-drainback valve some had but had my head "up and locked" on this one. I was about to attempt to bump my new motor off, and was pre-oiling it. As usual, the pump started increasing it's resistance (which happens every time the oil finally fills all the filters and galleries) and I was ready to start it up, but was troubled at the lack of "the dripping oil noise" in the pan that I usually get upon doing this. So I pulled one hose of the remote oil filter arrangement, and oil came out it fine when I spun the pump. I re-attached it, and removed the other hose going into the motor, and only a slight dribble occured when I was spinning the oil pump (damn, I thought!). Then after scratching my head, I realized I swapped the hoses under the headers at the block adapter. After swapping these hoses, I spun the pump again, and as usual the pressure (resistance) built up, but this time I could here oil dribbling inside the pan. I could just see it now, spun bearings, but I'd rather be lucky than talented any day. Quote Link to comment Share on other sites More sharing options...
pparaska Posted June 3, 2002 Share Posted June 3, 2002 Good lesson Terry. I NEVER crank up a new motor without first seeing oil pressue come up and oil coming out of all the pushrods/rockers, or cam squirter holes, etc. Quote Link to comment Share on other sites More sharing options...
blueovalz Posted June 3, 2002 Author Share Posted June 3, 2002 Well Pete, normally I would never start a motor without an oil pressure gauge, but in doing some welding in the engine bay, I accidentally severed (melted) the plastic oil pressure line going to my gauge. I guess I need to step back, take a deep breath and give myself another month to do this without trying to rush through it. Quote Link to comment Share on other sites More sharing options...
Lockjaw Posted June 3, 2002 Share Posted June 3, 2002 Rushing an engine job is a recipe for disaster. I make sure I have pressure on the guage and oil in the head, on an L engine. Very smart to check out your suspicion. Quote Link to comment Share on other sites More sharing options...
Guest Anonymous Posted June 3, 2002 Share Posted June 3, 2002 Good catch Terry, that could have been expensive. I'll stash that away in my archives if I ever deal with a remote oil filler. Regards, Lone Quote Link to comment Share on other sites More sharing options...
Two40MuscleZ Posted June 3, 2002 Share Posted June 3, 2002 Terry: Its uaually the little things that we seem to overlook in our "rush" for perfection, or in our case to get it "fired up and running". Good looking out...Glad to hear your rebuild is making progress. You and Pete keep asking about pics. Soon! Comps, Van Quote Link to comment Share on other sites More sharing options...
pparaska Posted June 3, 2002 Share Posted June 3, 2002 Terry, I forgot to congratulate you on a great catch, sorry. Oh, and replace that stinking nylon tube with a braided one! Sometimes, some of us are very careful and screw up anyway . What happens if you let an engine sit for a 8 yrs after building it without ever running oil through the passages (pre-lubing it on the stand)? In my case, a tiny bit of water or caustic solution sat in the back of the cleaned oil galleys and over time created some flaky rust that washed down into the main (and then rod) bearings and trashed the bearings and scored the crank right after startup. But then during the rebuild, I got the opportunity to throw a more radical cam in the thing, port the heads, put in a gear drive, diamond oil scraper, etc. - so it wasn't ALL bad.

DavyZ Posted June 4, 2002 Share Posted June 4, 2002 I think we need a "whew!" smiley. Good catch, Terry. Thanks for posting a VERY easily overlooked item---brain, file that away! Davy Quote Link to comment Share on other sites More sharing options...
Guest kc6wfs Posted June 4, 2002 Share Posted June 4, 2002 Great catch!!!!! My dad told me once of a problem of the same, but it was his friends. Just build a 454 with a blower, and reversed the lines. It ran, for a few mins while they set the mixture and started the cam breakin then started making all kinds of hell noises. And no they did not have a oil pressure gague hooked up. It did not make there day!!! Dave Quote Link to comment Share on other sites More sharing options...
