Thread: bottom end analysis

Tweet

Took bottom end of the engine to the machine shop , after getting the heads looked at , and finding out that they were trash and not at all what the were suppose to be. Well guess what , the bottom end is trashed. Luckily I stopped running the engine at the right time. The rod , cam and main bearings were toasted. This is after 30 hrs. on the rebuilt engine. Luckily the crank can be turned. But once again most parts were not what was disclosed when purchased. For those who have followed this adventure of the E Bay purchased 71 Nova, I once again contacted the seller to let him know of the machine shop analysis. His answer now is, are you ready for this?, the engine must have been switched by the carrier, in transit. After getting nowhere with him I called the dealership who sold the car for the seller, who is an employee of theirs, and they would like to have pictures of the torn down engine and parts. Looks like the dealerships reputation is at stake here. This is a pure case of fraud, listing all of the parts that are in the engine, which aren't. If I can't get anywhere with this approach, then a call to that states attorney general will be forthcoming. As Far as the machine shops analysis on the engine failure, they believe the oil cooler was the culprit. They have seen it happen over and over again. They say it's just too much distance for the oil pump tp pump even if it is a high volume pump or not.

I can believe that.

Good luck. you should be able to get your money back. Just be sure the pictures are dated and have your mechanic sign his name along with the bad parts.

Sorry to hear, Deluga.

As for the cooler being the problem, hard to tell. If metal got stuck in it previously, then it might well be. However, oil pressure is oil pressure and it is read after the cooler. Therefore if the oil pressure was good at first, then you could eliminate the cooler as being the culprit. My guess is your ignition timing.


Low octane fuel, timing too far advanced, too much compression, even overheating can all take out the bearings.

Be that as it may, if you are going to route the oil through the cooler again, make sure you flush it out thoroughly as well as all the lines.

If you haven't done it yet, might also want to make sure you have a copy of the listing on eBay stating what all the parts were supposed to be, If the dealership is at all concerned with protecting their reputation, a copy of this and the photos and doucumentation from the machine shop that inspected the engine should get you a refund, or at least the money required by your machinist to make the engine match the advertised specs.....

PS---Don't forget using the Better Business Bureau where the dealership is located for a little added leverage !!!!

Did you pre-oil the engine?

They have seen engine failure's over and over again.I have just one question.What about all Crown Vic Fords and LTD (ie police cars, taxi cabs?There must be thousands and thousands of them out there with out any problems.In fact my old Chevy work truck has one I installed and it has over 178,000 miles on it.Someone is giving you a bunch of B.S.I am not sure who it is but they are (clueless).If it is the machine shop you might want to look for another one.

Erik, you have a PM

I don't buy that the cooler loop caused the oiling problem for several reasons. Fisrt off though I am assuming you saw good oil pressure indications from a reliable gauge during operation of the engine.

Automotive oil pumps are simple fixed displacement gear pumps. In the absence of controls this type pump will generate whatever pressure it needs to drive the oil through its circuit based upon what drive HP you can twist the pump shaft with. Pressure controls are usually in the form of a pump internal relief. Also the filter pad on most engine makes has a pressure bypass check valve that precludes either the filter or cooling circuit from starving the engine main oil gallery. Otherwise on cold days most people would kill their engines due to the extra pressure drop across the cooling circuit.

I hereby throw my BS flag at the cooling circuit cause of failure ......

Good Luck, Kitz

My old toter (460 Ford) had over 150,000 on it, most of it pulling an overloaded trailer at 10 or so mph above the posted limit with a factory oil cooler on it. Never gave me a bit of trouble.......

what probably happened, they had blew a motor up with that cooler on it and didnt clean it out like they should and it picked up some old metal and thats what caused all of the problems. don't take but one little piece.

you may want to file a complaint with these people www.ifccfbi.gov and also with your local police department. I have been through this once and its a headache.

you should stay on this for many reasons.

I have been there before , but it was my uncle that shafted me and he did it on my first hotrod. this took place in 1991 when I paid him $4,000 to build me a sbc 350. after the engine went in the hotrod truck, he was nowhere to be seen, and after the engine was broken in the oil pressure was still to low , after about 500 miles or less the engine really was hurt. so I pulled the engine myself and pulled it apart, and found it had the stock crank, rods and pistons still in it. the crank was bad and 4 of the rods were bad. the only thing that he had put on the engine was a edelbrock carb and intake. a chrome engine dressup kit and a set of flowmaster headers. I kept asking where did the $4,000. go?
I told everyone what he did to me, I made sure he dont build engines anymore.

It1s10, You may have hit the nail on the head. I don't know if the engine was preoiled or not . I didn't build the engine. If they did not completely clean the oil cooler, if they had previously blew an engine, then all that crap would be pushed into the next engine.

heard of it a few times in round track cars.
