Machine shop query

[caduceus]

Just a quick question all. I had a new liner put in my Rover V8 recently by a reputable machine shop. I've noticed there is a lot of swarf and detritus in and around the block. After having this job done I was going to start to rebuild the engine. But obviously it needs to be spotlessly clean. Which it isn't.

My question is - after having machine work done on a block, should you expect to receive your engine block back clean and free of debris?

Yup, sounds like sense. I did wonder it might end up being that way. I think I'll try and find a local mc shop just to give it a thorough clean and blow out and bag it, ready for me to rebuild.

Thanks Mick.

Thanks for all the replies all. Please excuse my ignorance re what is expected of mc shops, etc. It's a bit of a learning curve doing everything yourself, but an immensely satisfying and valuable experience.

All machine shops do is put it through an automated parts washer, no more.
As said, the onus is on you as the builder, If you've got a power washer it's easy; Hot soapy water and bog brush to newly bored/honed cylinders, everywhere else lots of water soluble engine degreaser, tooth brush, dish brush, bottle brush then turn the power washer on it whilst it's off the ground (presumably on an engine stand). Dirt blaster nozzles are the best if you have one, hit every single orifice from both ends and spend a good 20 mins on the whole lot. Identify every hole and check it hasn't got somewhere the dirt can of hidden - dead ends etc.
Check it all over.
Dry it quickly (compressed air or in front of blower/heater) and WD40 etc onto the bare metal as it will flash rust in seconds.

That ^^ is better than any machine shop will do it.

I was going to take it to a local mc shop today who were going to put the block through their washer, but by the sounds of things this isn't going to anywhere near enough. So will be DIYing myself later.

Trouble is, I'm all out of room in my meagre single garage so I can't buy anymore equipment until I relocate, which I'm in the process of doing (readying my flat for letting, etc).
So I guess I'll be hiring a compressor and pressure washer for now.

• One question** - After I have cleaned the bejesus out of the block, crank and heads; Can the engine be reassembled with a coating of WD40 over it (to stop flash rusting), or will the WD react with the engine assembly lube and engine oil?

I have already coated the crank and block with WD a week or so ago and its preserving the polished crank and cylinders well. But this'll be soon cleaned off.

Thanks again. Appreciate the help.
