I have to get my engine out of my truck.
I need to know what does a complete 454" chevy engine weight. Somewhere between 300 and 400 kg or so?
It's pretty stripped now, but I'm going to throw it in assembled.

[Bumpstick]

680lbs give or take a few depending on whats installed...

Link for ya

Okay, so that's a bit more than 300kg. Thanks!

That is pretty cool that you two can talk to each other in your language.

I have no clue what you are saying , but it is cool anyway.

Sorry. In English. Seems that there was not enough oil pressure
at stationary. I have three piston skirts scratched, one bend push rod and a lot of clearance on the valve guides. Also on some of the valves there seems to be material "welded" to the stem.
The valve guides have to be replaced including new valves and new push rods.
I'm not sure whether to reuse the old (first oversize) pistons and polishing them, or to get new pistons.
Next to that, the thread of the balancer bolt has been damaged in the crankshaft.
So I could also buy a complete balanced rotating assembly at Jegs. Its a matter of money I gues.

Pulled the engine out of the Suburban.
Only the bare block is light enough to lift on my own. With the crankshaft in, it's to heavy.
As I can see, it's been overhauld with 0.03 pistons in the USA, shortly before it was sold to the Netherlands.
It was completly wrong honed. The cilinderwalls have a mirror like finish. No oil was able to stick to the walls, resulting in three worn pistons.

[Pieter-GS]

The rest of the pictures:
As you can see in the last picture, the hone lines are horizontal instead of crossed.

Those are not just worn pistons... They look to have been very hot and swelled in the bores so they scored which can be due to either running the engine hot or to lean but can also be caused by a way to rich condition which will wash down the bores/rings and cause them to scuff like what I am seeing in your pictures...

Also after reading your earlier post with problems with the valves too I would think heat again has caused this and possibly to little lubrication...?


Also just a thought but the last time I saw and engine in the shape it was a strange thing... A guy had changed the oil in a 4 cylinder diesel engine in a manlift and had put reg Hyd oil instead of motor oil by mistake and just about the same thing happened...? What do the bearings look like...?

[Pieter-GS]

It was warming up from start up to adjust the timing when it stalled.
Bearings of the camshaft looked fine.
Big end bearings had normal wear and only the last crankshaft bearing had to excessive wear while this one looks to be out of line. Needs to be line-bored.
