Re: 66 frame off resto-mod
Well, still going round and round with the salvage yard trying to get the new engine and trans so as it stands now, I don't have a good motor, I thought this project was going too smoothly...

While we try to get a good engine RRC had some time to figure out the fuel pump.
Attachment 472002 My existing tank was located in back, not sure if it was custom made or not. Attachment 472003 We still need to clean the inside of the tank, but I wanted to use the stock fuel pump and sender so here is the solution. Attachment 472004 Attachment 472005 Ant it all completed ready to feed somthing. Attachment 472006 |
Re: 66 frame off resto-mod
Dont know if it will help, but Vector Motorsports just did a engine and trans tune for my G8 that has the six speed auto. They actually sent me two different tunes so I could load the one I liked the best - stage 1 and a stage 2.

Help...
No new photos, but renewed frustrations with the junk yard where I got the motor. The 6.0L they got in for me all of a sudden they want an additional $3,000 for and I can't afford it... This is after waiting for weeks for the promised replacement so now I have to try to get my money back from these guys and find another motor or have a shop look at the existing 5.3L. The shops I have spoken to want $200 just to look at it so I need to get some ideas of what it might be.
Does anyone have any insight as to why a roll over 2008 5.3 would have a tight spot when rotating the crank a full revolution? We are rotating it without the plugs and it gets very tight in one area of a 360 degree rotation. Now for the strange part, if you are turning it with a ratchet and can get some momentum before the tight spot it will glide past it, but if you turn it slowly it takes a fair bit of force to get past this spot. When I say a fair bit of force, the starter cannot start spinning the motor if it lands on the tight spot without the plugs in. The yard told us to try spinning it with oil in the pan in case some rust developed in a cylinder and we did, but no change, the tight spot is still there and appears the same. I wouldn’t think it would be a valve because a single valve wouldn’t open on every 360 degree revolution so would that mean lower rotating assembly? Any of you have any ideas what it could be? If I have to replace a rod, pin, or piston would I have to have the entire rotating assembly re-balanced? |
Re: 66 frame off resto-mod
I agree with you that if it does it on every rotation that it is in the lower end. Sound like the crank could be bent, either way I would guess that if the starter can't move it from that spot there is definitely something expensive wrong with the motor and unless the yard is going to pay to fix it I would get your money back. That's my MHO anyways. Best of luck and let us know how it turns out.

More info, we checked with a bore scope in the plug hole didn't see anything abnormal, any other ideas on what could be the issue with the 5.3? |
Re: 66 frame off resto-mod
I am by no means very knowledgeable on engines, but if I remember correct, they have mechanical oil pumps, could there possibly be something binding in the pump? Have you pulled the oil pan? I think the pump can be removed from the bottom.

Re: 66 frame off resto-mod
Sorry to hear about the junk yard, that sucks good lesson for the rest of us.....get it in writing.

Re: 66 frame off resto-mod
Of course the same can be said for the water pump. Is it driven by the camshaft like the LT1?

Re: 66 frame off resto-mod
if you drop the pan without their permission then they can say that you tampered with it, then they will explain to you that you are "SOL". if you are doubtful about any of just try and return it. don't give them any opportunities by being a good guy to stiff you

Re: 66 frame off resto-mod
or you can let them have the opportunity to chk it out themselves and if they say that it is fine, then that puts the onus on them. the greatest problems with these things is the time that these motors sit around before they actually get on the road. sorry i don't recall on how long that you have had it it. if not that long then I would say flash it up and see if it runs. just make up a simple engine stand and do it. or find and eng shop that has an eng dyno and get them to do it. if it goes for a dump then they sold you a motor that doesn't work and you haven't opened it up.
everyone tries to weasel out of everything , just get tough or smarter than them. I can remember back in the mid 60's when a friend had bought a falcon I think with a nice little v8 in it(he had previously worked for Ford) and had some concerns about the eng and he only had about 350-400 mi on it. he took it in and the service manager told to go put some more mi on it and to see what happens. ford had a policy then if there was a problem under 500 mi they replace the eng and if it was over repair. he went home with it and dumped the oil and took it for a drive and it didn't make it to 500 mi. new eng. That is hardball, but sometimes it has to be done ron |

Thinking about it, the cam should rotate once for every 2 crankshaft rotations? The oil pump looks like it is located behind the front cover on the cam so if it was the oil pump I would think it would have a tight spot every other full rotation. Any other ideas? |

I can hear you on the budget build! but depending on what kind of yard it is, they may definitely know what they are doing trying to sell you a bum engine full well knowing what is wrong with it. I know that sounds harsh but like everyone else I am sure they are having a hard time as well in this economy. |
Re: 66 frame off resto-mod
sounds like it spun a bearing , if the motor ran while it was upside down then there was no oil going to the bearings , if your lucky it was on the rod or crank , it could have messed up the blockside bearing and messed up the block and thats not good , but most of the time its a rod or crank cap bearing .
