We just got back from McIntyre last night after having been there Wed.,Th, Friday. The weather was awesome and the park was nearly empty BUT 15 minutes into boating upriver the first day, my motor starts making a horrible clattering sound. Can't hear anything at idle but even enough above idle to move slowly against the current brings it on loud.
At first I figured a loose rocker arm but ruled it out because why would a rocker come loose after 30 years? Now I'm thinking collapsed lifter. We ran it quite a while at near idle but it never misfired or stumbled, just a rattle under power.
I know I can't just put a new lifter in, and so I'm probably looking at a top end job. Generally new top ends destroy megamileage bottom ends (at least that has been my experience) so I'm wondering what to do? I have engine building friends who say that building 500 ft/lbs of torque with the Olds ain't that expensive. I think that would be enough power. Maybe I should just replace the cam & valvetrain and see what happens down the road.
What say you?

Gonna throw this at you...

Chances are you flattened a cam. Where do you think all those itty bitty particles went?

I call it motor time, building a good Olds would be my vote, not because you already have one, but because you seem to have extremely good luck with it...

But then again it may be just me....

Sorry you blowed your chit up right before summer....

Damn, I have that Olds sitting in my storage unit from when I wasted the Pistons. I have this for a cam : JB-3H Olds Gen II Hydraulic Lifter Camshaft from Shneider Racing Cams. I was pushing almost 500hp with K series heads and a bump for compression with some Keith Blacks. I built the Olds for around $2500. I went back and forth from Olds to Chev in my head but after I blew it I decided that Chevy makes a more reliable motor anyway. Not near the problems and I built my Gen 5 block for around $3500 starting with nothing. That includes the swaps for exhaust, mounts etc. Anyways, if you need something let me know. If I have it I can try to get my gf to grab it outta storage. Kinda wished I could've made that Olds work just for nostalgia.

GT the Olds is like most other motors, treat them right and they run forever. I believe this motor is original to the 1973 hull, but let's face it, nobody ever hot rodded my barge. A big heavy (even for a 23' daycruiser) jet is not going to win any races so why try? It still has the GM carb and intake and J heads. The hour meter broke way back at 353 hours before I got the boat.
I liked the Olds simply because it was an alternative to the sheer ho-hum-ness of a 454. I will never own another GM car/truck but if it was already in the boat I would run it. Up until now, it was the expense of hunting down exhaust, mounts, alternator etc. that kept me from building anything else. For this cruiser, unless it had something seriously bad ass lurking in the shadows, an Olds just seems to be the right call. I have given serious thought to Pontiac and Mopar power in the past, but I was expecting to have more time and money to build one of those.
Challenger send me some contact info if you want to sell the cam set and the heads if they are salvagable. I have access to a few pretty good machinists.

The same thing happened to me last season...... Coming back from Topock to Havasu ,I was hauling arse down the river and heard a loud metallic sound from the top end .... i nursed her back to the trailer thank god . I went home and tore the valve train apart and found my number three lifters head sheared off ...... Everyone on the site told me to pull the plug and rebuild ..... So i bought a new lifter set instead LOL because i am a Hard headed SOB some times ... Anyways I flushed the motor three time to try to get rid of the metal chips and I installed the lifters .... i shook down the boat locally ran fine .... I though I had the last laugh .... I trailered the boat out to Parker the next weekend and threw my rod 75 ft from the Boat launch ramp ..... All that metallic shrapnel smoked the bearings and i was lucky to not have lost my boat when the rod punched through my oil pan ..... Do your self a favor and yank it and rebuild it .... you can be back on the water in a few weeks with confidence ... in fact GT And Rebel were the ones who advised me to yank it .... they know what there talking about ..... Good luck

LMAO! But I do agree, I think you either flattened a cam, and/or spit some lifters from their bores!

Time to man up and yank it John!

When you get into it, get with Harry. I think he had a set of K heads, some cranks and things he was anxious to get rid of.........

GlassCutter · « **Reply #10 on:** June 11, 2011, 08:22:48 PM »

For $100 I just bought 7 used 2323F Speed Pro's with rods, and number 8 is $45 from Summit. I have a good std block, aluminum intake, and a high nickel crank in storage. I do need some better heads than the J's that I currently have though.
This still feels like putting lipstick on a pig.

And Ray, I cannot in good faith use that for sig material. I have my standards. Frankly the way you "out" yourself so often, I am beginning to wonder if you don't belong more with the Vegas crew. Besides Beerjet keeps me pretty well supplied with classic Omarisms.

IRRebel · « **Reply #11 on:** June 11, 2011, 08:39:58 PM »

LMFAO, John, that's why I love ya! Jeezuz it's nice to have teachers around......

Be VERY careful on the replacement pistons........Old Speed Pros are not always the same as NEW Speed Pro's............Found this out the hard way on Moo 1.0. But the 2323F is a flattop piston that SHOULD give you around 10:1 compression with a J head. A little more with a K.

Why are we worried about pistons and crap though? A few spun bearings, maybe you have, I doubt any more than that is unsalveageable. Now if you REALLY wanna hot rod it while your at it.....well that's a different matter. I wont tell...........shhhhhhhhhh!

And I want pics of your wife in the 'kini......To hell with good faith and all that.........lmao!

Because if this thing has to come apart, first it is coming out of the boat. At the same time I want a new one to go back in with no down time. And if a newly massaged .60 over hipo cammed Olds won't give me the performance I want then I will start working on a motor program for the Spectra.
And don't you dare send me any links to anymore Pontiac or Mopar stuff cuz I really get sidetracked easily. If any of my Mopar stuff was still in Cali instead of Utah . . . I wonder how a set of 3 two barrels feeding a 505 cubic inch monster Mopar would run in a daycruiser. Maybe throw on a Magnacharger just for that extra 150 horses. Nah that would be crazy

LOL, Just so happens I have a running Olds kinda sidelined here. I've been threatening to throw the 514 Ford from the garage in it if the pump don't get here quick.........

GlassCutter · « **Reply #14 on:** June 11, 2011, 10:20:26 PM »

OK Ray here's what I'm thinking now. Send me that 514 and I'll make it look good in the Spectra. And then you will have the perfect daycruiser and a nice newly unemployed 460 to install with it, plus a bunch of mix n match 455 parts. I know how you like da Big Ass Boats and mine would be so nice with a nice stock reliable Harmon Marine 460.
C'mon now, you know you want to. I know the girls say size don't matter, but we know that's b.s.

Just the beginning for John. See, he's a teacher..........and they just tend to over think things to the point of obsession.........I was married to one for years, and survived to tell the tale........

What I REALLY wanna know is how MRS GC feels being that photos of her are being pimped out on the net for a new motor............

Just wondering....have you taken 10 minutes and pulled the valve covers yet to get a look at what might have happened yet?

GlassCutter · « **Reply #20 on:** June 12, 2011, 09:08:11 AM »

Ah finally getting this thread back on track, thanks Pat.

I didn't pull them at the time because I was afraid that I wouldn't be able to find any Olds gaskets in Blythe and I didn't have any hex wrenches. Now I'm home and I haven't even finished unpacking cuz I'm a lazy ass. Monday I am going to register the Spectra, hook up a fuel line, and go get her wet. I'm hoping I can play the rest of the summer with it and work on the Wriedt as time allows. I really want to teach my boys to ski this year, and the Spectra is really a better mule for that. Also, truth be told, the Wriedt really needs to have a new subfloor and some other repairs to the interior.
Never having been inside of an Olds, what exactly should I be looking for?

lbhsbz · « **Reply #21 on:** June 12, 2011, 09:34:09 AM »

Look for stuff that doesn't look right....loose or broken stuff. Could be anything....no fence throwing a bunch of money at a new build without first at least finding out what happened. At the very least, it might be educational as a "what not to do" on the new motor.
