At least you have all WINTER to fix it and not all summer...That would really suck. Hope you find something minor

Chuck,
Man oh man.. that really sucks. But 4hrs and you were running for that long?? What kind of clearances are you running on the bearings? You should have more psi at wot.. more like 60psi. What weight oil are you running? I am runing a 15w/40 synthetic and see 60/70 when cold and 60 when hot.. it does go lower when it is hot but usually to about 40 at an idle...
I hope it isnt serious.. and having more time this winter you can take your time and find out what happened and make it right..

Good luck and dont give up.. when it does run, you will forget the grief!!

Dick

That really sucksd. Last time I broke was on the way back from Port Huron. I had just entered the South channel at the North end of Harsens when the timing chain gear on the crank broke (stupid Comp Cams). When we left that morning the guys in the other boats asked why I had so much beer and I told them "you never know what's gonna happen." needless to say 12 miles and 4 hours later on one motor I too had a pretty good buzz going. Good Luck.

I hate to say it but it sounds like a Main Bearing went
south. Same thing happened to me with a 455 Olds.
The bearing was bad and TRW never backed it....New
crank and Clevite bearing set for me in a 71 442 Olds
4 speed.....I hope I'm wrong in your case, Mike.

I had the same deal this summer after chasing an water leak (into the oil) for a couple weeks the 2 front mains washed out ... I pulled it hanged the head gaskets intake gaskets sealed all the bolts I could think of flipped it over pushed a set of mains in and bolted the thing back in....Ran the rest of the summer so far!!I'm taking it back out to grind the crank in October.
Good luck!

Just curious 26Scarab... what is your oil temp normally? My engines run about 220F after fully warm and I try like hell not to get into them hard until I get a least 200*. This takes 5-10 miles at 3200rpm usually. Is it possible you got into it (them?) too quickly and starved the mains? The only other thought would be an oil contol problem in the pan. Of course, the first step now is to cut open you oil filter and start fact finding.

Keep your chin up... and good luck, hoping it's something simple,

Mr. Gadgets,Blue Thunder,
This combination has been together for over 80hours. I just recently had to go thru it do to a lifter problem. When I took it apart for that I decided to ring and bearing it. The original bearings looked fine but I figured it's this far might as well change them. My engine guy checked the clearances and I did the assy. I really don't know what they were since it wouldn't mean anything to me, I'm not an engine builder.
Before I took the motor apart it would run around 48-50lbs of oil pressure at WOT (hot 170) and at an idle it would be around 30 (hot) , I was told this was due to rod side to side clearance which was high but not excessive. (Eagle crank)
Everything was the same after I put it together, I did notice about a 10 degree rise in the oil temp (still never over 180)but I'm running 15w40 instead of 10w40 like last year so I figured it was just the thicker oil.
My engine guy seems to think it is something stuck in the oil pump bypass thing. This is because when I fire the motor up there is oil pressure and if I give it a little throttle the pressure will climb. I don't know and don't really have the time to dick with it (55 hours at work)so it will sit until I can find the time to pull it.
I had a good season, now this time I can dyno it before it goes back in.

26scarab... seems to me your oil temp is too low. I would consider an oil thermostat system to get the temp up to around 220*. Other than that, I tend to agree that the pressure control valve could be failed in the oil pump.
