Engine moved back

Maintenance/Repairs
1

I had a small wreck Tuesday night my front end slammedd into the wall engine was untouched but however i did notice it was moved back a little, could it harm it in in any way ? Whats some stuff i should check before i turn the truck on and move it? I drive a 2005 silverado single cab engine was a 4.8 swaped to a 6.0 not long ago

Without actually seeing it I can’t answer your question but I will say this.
A strong impact can damage an engine; either externally or internally where it’s not visible.

The engine being moved back could point to a buckled frame/subframe and/or suspension issue.

About all you can do is eyeball it for leaks, monitor it for noises or oil consumption, and note how it drives while paying attention to things like pulling, wandering, etc.

I assume by your post you’re just going to move it but not drive it any distance.

If the engine moved back so did the transmission. Just be sure it didn’t move back far enough to jam the driveshaft between the rear & the transmission.

IMHO the entire drivetrain needs to be checked out. You could have damaged the engine (which in this vehicle is longitudinally mounted, with the crankshaft possibly having sustained a direct hit), the transmission (hopefully it’s a manual), all the shaft seals associated with both, the U-joints, the pinion and ring gears in the differential, even the carrier bearing. And don’t forget the engine & tranny mounts.

If the engine operates without unusual noises and there are no signs of leaks, and if the tranny shifts normally and operates normally, and if the rearend doesn’t whine and the drivetrain doesn’t thunk or make noises, you may have lucked out. I would not recommend disassembling too much unless you detect some sign of damage. I’d suggest a good thorough look-see on a lift complete with shaking the driveshafts and checking for excessive axial play in the pinion shaft, along with a good test drive and perhaps manually shaking the engine to test the mounts.

Let us know how you make out.

Wow the big engine ,moved a bit eh?Looks like in a front impact the engine itself would have moved forward,maybe high G launches causing the old mounts to shift?
Seriously I think the frames on these trucks are designed to “accordian” in a frontal impact,so really peruse the frame-Kevin

Thanks guys comment gave me alot of ideas on what to look into. I will keep you all posted.

I’m having trouble imagining how a frontal impact could move the engine back; seems like it ought to be moved forward in the compartment if anything.

Any chance the engine swap has something to do with this?

I dont know if you can open the attachment but you can see here how it moved

If you can open your doors it’s not too bad. If airbags are not popped than that’s also a good sign.

Am I seeing that the front wheels have also moved back?

11

I would suspect that the cab might have shifted forward on frame.

12

Good point by @Rod Knox. This might also mean that the engine didn’t shift back in relation to the frame. Good observation by @insightful.

Is there space behind the cab ? Between it and the bed ?
I’ll bet they had the cab off for the engine swap ( we do that every day on F350s and heavier )
