(Cracked Block) - Sudden Milky Oil - 351w

Exhausts or intake would be my guess. Spark plugs dry?

Andy,
Since the plugs are dry and you did pressure test the manifolds, I as Gary mentioned, suspect somethings up with the intake manifold. Check the T stat area real good. The area has been reported to be a problem.

Andy,
If you don't have a Magnaflux Spotcheck kit I suggest getting one.

Well you guys were right about one thing; pulling the intake did find my problem. Too bad it's a crack in the block. Didn't need the crack checker to find this baby, hell Helen Keller could have found this thing.

That is too bad

Actually it was quite foolish of me to think that after rebuilding every other part of the boat the motor would be any different. In reality I'm still quite lucky, (as I mentioned it before) the problem presented it self by puking oil all over the place on my warmup run last week. Had this not happen I would have probably smoked all the internals skiing that day. With oil pressure still at 40-60 psi and running like a champion I have no reason to believe the rest of the motor is bad.

Looks to me like it's pullmotorfindblockrebuildmotorcocktailtime.

Bummer. Junk yard 351 and a few gaskets and you're in business. I'd look for a 1-piece block and get the RH seal on order. Don't forget the new damper!

Sorry to hear that, but I have to say, you don't waste any time moving forward!!

Sorry that happened to you Andy, after all that hard work and how excited you were to get it out on the water. Clearly you have the ability to address it,   Hope to see having it out on the water again soon.

and a 95 bronco or f250 is likely to have the roller lifters and spider present, but if he is going back to a RH engine the cam to go with them is something that doesn't exist in the wild

After calling in every favor I could I manged to scrounge up a few potential blocks. I also called a couple engine shops to see what rebuilds cost these days.

Here are the current options:

1 A.) Pull the head and see if it's fixable. If it is; send to my friends brother to nickle weld the water jacket, install a new head gasket, reinstall the intake and give it another shot. ($200-$400)

1 B.) Same as 1A, but trade some fab work for a set of re-manufactured heads and install them with 2 new head gaskets after the repair. ($300-$600)

2.) Get a parts 351w from a friend, strip & dye check the block, buy a rebuild kit & send it off to my friends brother for a top to bottom rebuild. ($600-$1000)

3.) Send the motor to a local engine builder; new block, rings, pistons, bearings, gaskets, rebuilt heads, returned ready to install, with a 3 week lead time and a 1 year warranty ($3200)

4.) Pick up re-manufactured long block with 2 yr warranty, buy new exhaust manifolds, new damper plate, dye check my intake & swap over the rest of my gear. ($3000)

Option 3 and 4 would normally be off the table, however my parents completely shocked me and showed some interested in donating to the cause. Perhaps it was all those years of yard work when I lived at home or maybe they just want unlimited boat rides. Whatever the reason I'm not going to turn it down, every penny gets me one step closer to the lake.

As for the rest of the money I'm going to have to get creative. That being said if you happen to know anybody looking for a custom Nautique bar, fabricated parts or CNC plasma signs, you know where to find 'em

how much for bar

Not nessasarrly

I had started haggling for these heads before I was aware of the block crack. Just like Tim I like keep piles of spare parts around "just in case". Although they were stock heads, they were recently rebuild and had no more then 20 hours on them. Doesn't much matter, I'm not going to need them now. Instead I'm going to do something I didn't think I would do; sell my boat.. Of course I'm talking about my 66 MirroCraft . Selling the boat + a little shop work should get me enough for a re-man 351w long block, a new damper plate, new water pump and a transmission kit. With any luck I'll have it assembled, broken in and on the water in a few weeks.

Sure hope it works too because I'm selling my only good boat to fix the broken one.

Agree with joe.

RH rollers exist, just not in the wild!
