So you picked it up? How's it look? Where you at now on the build?

Wouldn't you have studs in your bad block?

Engine is in the mail.. there were some complications with shipping because I don't own a forklift.

So it came today.. Cylinder walls look okay... the engine was kind of seized and left in the weather so I'll see more once I get it apart.





^ it looks like it has a blocking plate on the oil pan for whatever sensor is on my engine.. I think it's the oil level sender, or temperature sender.

It's an oil level sensor.

What's the best way to clean and polish these cylinder walls? I want to get rid of the buildup but I don't want to damage them or use the wrong chemicals or too abrasive of a cleaning pad... what's the protocol here? Is it bad to use WD40 on these sensitive and special cylinder bores to clean out the grime?

I'll be moving my internals to this engine after I get it apart and cleaned.

Also, should I keep the oil level sender deleted or add it back?

Pics of the bores? What is built up?


Also, my 86 didn't have the sensor, but my new 87 motor did. The sensor is in the pan, but obviously not hooked up. Your call on that.

Are you talking about that crusty carbon at the top?

Yes, clean the crust from the top.. I don't want it getting pushed into the cylinders when I install the new internals.

The engine wasn't seized badly, but there was a rust line on the cylinder walls from the rings when I gently moved the pistons. I moved all pistons to TDC and gently brushed the crap from the top of them (so the crap doesn't fall back into the cylinders) but I want to make the cylinder walls spotless before I install the new internals. I can't leave them alone, what's the best way? Oil and a rag? Brake cleaner and a rag? WD40 and a rag? I've heard about something called scotchbrite, is that a good idea?

I'll post pics of the bores tonight

Best to clean the lip before you pop the pistons out the top otherwise it can gouge up the piston.

WD40 works if you're patient and let it soak. It's perfect for wiping everything down to clean. I have a few soft bristle plastic brushes that I use for delicate cleaning. You can also scrub it lightly with a red 3m scuff pad but don't get carried away on the bare nikasil... you can mar it up without much effort. The use of a scuff pad should be limited to the top of the tar/crust that you're removing and not any of the surrounding cylinder wall or OEM coating. You may notice large chunks come free with your fingernail or a plastic blade... again give respect to the surface even when using soft working materials.

I've used oven cleaner in the past which is quite a bit "hotter" than wd40. I would take great care to limit the time the acid is in contact with all engine materials. It has potential to burn your skin/eyeballs and can cause severe damage to the engine if you don't rinse completely. Works but not my recommended method.

It got a little warmer.. Oiled the cylinders today and cleaned most of that black crud from the top of the cylinders..

I think I'll have to use my flywheel to get the crank bolt off, the block didn't come with a flywheel or clutch as advertised

I've got it pretty disassembled so far.. just need to remove the crankshaft and plan my strategy for cleaning it, getting it on the stand and swapping for the other internals.

I think I need new rod nuts, or am I mistaken? I used new ones on the trash block but they've been torqued.. are they stretch nuts or can I reuse them?

Nice thread! Truth be told, on my build, there was no talk of Alusil...i just told my guy it was out of a Porsche, it was aluminum, and that it was very special. He assured me that he knew exactly what he was doing.

I have been running 16-18 psi for 20k+ miles. I guess it was good enough.

Kinda scary though...i almost want to call him and ask what he did, and how he did it. Or if he has no recollection, how he would do it.

...Anyway, keep up the good work!
