Guest Anonymous Posted April 11, 2000 Share Posted April 11, 2000 I bought a 350 chevy motor today that is brand new rebuilt, and the nuckleheads started it with no oil and then tried to put oil in it and, well you know!, anyway I got it dirt cheap,150.00, has edelbrock intake and carb,chrome covers and breather, all new!!new alt ,starter,ac compressor. BUT!! it has lots of shavings in the pan and 1/2 of the rod bearings are GONE!! How should I flush out the heads, and do ya think they will still be ok like they are? ------------------ 74 260, early 350,K.B.pistons,edelbrock manifold,carb,and cam,202 cast iron heads.Let the transformation begin.

Did the engine ever start or did they just try to start it. If it has hydrolic lifter, it may not have started due to no lifter pump up. I would be concerned about the cylinder walls and rings as well as the bearings. If it ran with no oil you may need to rehone them or maybe over bore the block. I do not understand your question about flushing out the heads. But if the engine did run and they forgot the oil did they forget the water as well. Heads could now be warped if it ran hot and need resurfacing. If not just ckeck the heads for excessive valve guide wear. Hope this helps. Let me know how this turns out. It still sounds like you got a deal. Bubba Fett Quote Link to comment Share on other sites More sharing options...
Guest Anonymous Posted April 11, 2000 Share Posted April 11, 2000 No , they ran the motor for a good while,and he said it just started knocking real hard, they are a couple of 17 yearold boys, I just kinda figured they didnt have enough oil in it ,when I pulled the pan it only had about 1 1/2 qt of lube in it.he ran it for an hour or so before it started to hammer. then it was started several more times to let everybody give their opinion as to what was wrong. I knew as soon as I heard it, it was toast!he wanted 300.00, and I left him my card and an offer of 150.00, he called and said he was sick over all the $$$ he had spent building it , but he was done, so I got it right. I was planning on getting the block redone, but I was just wondering how much of the metal got pumped upstairs ------------------ 74 260, early 350,K.B.pistons,edelbrock manifold,carb,and cam,202 cast iron heads.Let the transformation begin.

If the oil made it there it should be ok. If not it should not be hard to clean up. Were the heads of the hi po variety or just somthing the kids threw together. May not be worth the trouble of fixing if there was indeed harm done. Bubba Fett Quote Link to comment Share on other sites More sharing options...
Guest Anonymous Posted April 11, 2000 Share Posted April 11, 2000 well they appear to be stock castings, but he said they had bigger valves but didnt know what size, I havent pulled them yet,but there is some very fine metal dust under the valve covers. I will be tearing it down for more inspection next week. Gotta pour a slab in my new "Z" CAR workshop this week. good luck with those u joints.

MYRON Posted April 11, 2000 Share Posted April 11, 2000 Takman, You may also have crank damage. Take it to your local engine house and have it redone. They will tell you if the crank has to be turned. It is possible to turn the crank a few thousandths and be ok, but some time they will have to turn it down more and that would not be good. I suggest that you bore it .030 and put a good set of flat top pistons... The machine shop can also check out your heads for cracks and warpage. After they check out the block for damage you can supply them parts for the rebuild for cheaper than they charge for the parts. Quote Link to comment Share on other sites More sharing options...
Guest Anonymous Posted April 27, 2000 Share Posted April 27, 2000 Hate to admit it, but the first time I rebuilt an engine (it was a learning process, damn it!) I installed a rod bearing upside down. So that bearing stayed pretty dry. I was pretty proud when I first started it up and it ran great.. and it ran slower... and slower... and slower... and died. After trying this a few times, I gave up and pulled it apart. Yes that bearing was nice and shaved, but the shavings stayed in the pan. I didn't remove the crank, I just slid in some new bearings. That worked for a few months then that bearing completely disintegrated and I got that horrible knocking while driving on the highway. So this time I had to take the crank out. Being generally ignorant, I went ahead and bought a new crank for fear that all that slapping may have been enough to bend the shaft, but I guess I should have had it checked. No biggie, got a new crank for $50 at a junk yard, had it turned for $20, and was back in business in a few days. I don't have the car anymore (donated it to my sister), but it's been running for over a year now and is happy. I would expect that these guys did something similar if only one or two bearings were shot. Quote Link to comment Share on other sites More sharing options...
Guest Anonymous Posted April 27, 2000 Share Posted April 27, 2000 well the boys bought a long block, from a fairly reputable engine builder, but they messed around so long before they installed it , they had no recourse to return it for warranty repair. But now that my shop is almost ready I plan to go in a little deeper before I decide which motor to use, I have three buildable motors, I am sure I can make two nice ones with what I have. ------------------ 74 260, early 350,K.B.pistons,edelbrock manifold,carb,and cam,202 cast iron heads.Let the transformation begin.
