questions/problems on a replace engine FIXED - SORT OF

[tie_one_on]

I had to replace 1 of the engines in my boat due to freeze damage.<br />1988 Ford 302 Pleasure Craft straight inboards.<br />This boat has twin engines.<br />I replace the engine with a rebuilt long block.<br />Transferred all my old parts over.<br />Now when I start this new engine the water out the exhaust is foamy/oily. The other engine is nice clear smooth water.<br />Also, this rebuilt engine doesn't run smoothly at all. It will idle fine, but when you give it gas, it spits & backfires.<br />I rebuilt the Holley 4 barrel on it. Still doesn't seem to help.<br />Any ideas to check?<br />Where/how can I hook a vacuum gauge to this carb? The big hose running to the pcv valve?<br />Thanks for your help.

Alot of things come to mind.<br />Is it counter-rotating?<br />Was the original?

Make sure the ignition is in proper form. When a new /rebuilt is coughing sputtering on first startup, it's usually something wrong there.

standard rotation on this one.<br />My biggest fear is a poor rebuild job.<br />I say this because the rebuilder didn't run a tap through the damper bolt hole nor did they remove the water jackect drain plugs when they vatted the engine before the rebuild.<br />I had to buy a 5/8" - 18 tap to retap the damper bolt and had to redrill one drain plug and retap with a 1/4" pipe tape, again which I had to buy.<br />My biggest concern is if this rebuilder cut corners on this simple stuff, what did they do on the major stuff?

My biggest fear is a poor rebuild job.<br />

Let me guess, he was also the lowest bidder, right?<br />Everyone always wants the lowest/best price for everything, when it doesn't work, they want the service and warranty of the most expensive place at the price of the cheap place....... Right??<br /><br />Look at all the threads here asking for best price, not best quality.<br /><br />BTW, I don't expect an answer either

Now this is info based on a stock motor not one<br />with a fancy cam grind with overlap or other<br />performance grind conditions.or any non stock items<br /><br /><br />The water problem, if all seals , plugs<br />general piping hook-ups are correct then:<br />Head gasket on backwards/upside down, wrong one.<br /><br />Intake manifold gasket misaligned/wrong<br />manifold cocked<br /><br />valve timing, chain off a tooth or cam sprocket aligned with advance/retard position instead of stock, 180 deg off<br />Back fire timing related, effect of mis aligned<br />timing chain to gear, crank.<br />Distrubutor in 180 deg out.<br />check firing order.<br />Verify top dead center condition of crank<br />and #1 cyl valve train closed.<br /><br />That should keep you busy.<br />Remember you are there, your eyes see<br />don't let anyone tell you what to do<br />check all spec from eng manu books<br />follow install instructs from proper<br />manuels/procedures. Only you can<br />repair it, I can only throw out possibilities<br />and would never tell "this is what it is"<br />Good Luck

No Don S it wasn't the cheapest (and so what if it were?). <br />If you have good suggestions of things to check please offer them.<br />If you want to be a smart a$$, take a long walk off a short pier.

Reminds me of a song, Bad to the Bone, doctor said leave this one along, he's bad to the bone. I'll be surprised if there are any more responses to this thread.

bama .....<br /><br />Sometimes I can't help myself. Seems like this 'rebuilt' really wasn't 'rebuilt' and should have been the "cheapest".Maybe it was rebilt.<br /><br />Also to ask advice,and then call responders smart a$$$$ seems to me to be a bit in poor taste.<br /><br />But what do I know.Don S. is such a newbie here. So who can vouch for him (GRIN)<br /><br />DHP<br /><br />Bad to the bone ..... ROCKS

Transferred all my old parts over. <br />Now when I start this new engine the water out the exhaust is foamy/oily. The other engine is nice clear smooth water.<br />Also, this rebuilt engine doesn't run smoothly at all. It will idle fine, but when you give it gas, it spits & backfires. I rebuilt the Holley 4 barrel on it. Still doesn't seem to help.<br />

I Guess I'd be looking at All the Stuff you Reused from the Frozen Motor,.........<br />Maybe an Oil Cooler is Leaking into the Cooling water stream,.........<br /><br />And,...... Backfires are Usually caused by a Lean Condition,......<br />Your Holley may need a more in-depth Rebuild,.. or even Replacement......<br />Or,.. Maybe it's just a Vacuum Leak,..??.....<br />

Also to ask advice,and then call responders smart a$$$$ seems to me to be a bit in poor taste.

And,..... While I'm here,.......<br />Any Grease IS, in fact Better than No Grease At All,........<br /><br />Having Some Antifreeze,...... Probably would Not be Any Good At All,.....Matter of Fact,... There's Plenty of posts going around that people have Frozen their motors from Poorly Winterized Anti-Freezed Blocks Too..........<br /><br />Just because YOU can't figure out HOW to Thoroughly Drain your Block,..............<br />Doesn't make it All Right,...... To continuiously Harrass Me with Your new tag-line........<br /><br />My Information Was,+ Is Still Good,........<br />And,... It's Not My Fault that You Screwed it Up.................<br /><br />Good Luck,............

I found out why this engine ran so poorly.<br />Turns out the rebuilder sent me an engine with the 1-5-4 etc. firing order instead of the 1-3-7 etc. firing order.<br />I'm interested in seeing how he intends to handle this.

I really like it when people give<br />updates.<br />Very good trouble shooting.<br />Best of luck
