SC 1982 Engine rebuilt - help needed please
Today I have been taking out the engine with the help of some friends...
Here it is at my garage.  It will need a very deep and hard clean... As you can see there are a lot of a white powder over the bare metal, like cases, valve covers, chain covers etc. Black parts are easy to solve because I will dismantle everything, recover the old rusty bits and paint it. The problem is the other parts... Does anyone can davise any product to help removing this white powder permanently and refresh the bare metal parts? Specially products I can purchase in Europe - there are some products from US that are very expensive to import...

I have been searching some information about the works previously done on the engine and found out that head studs have already been changed by reinforced ones. Some maintenance has been done during last years.
My plans for now: Change all rusty bolts and nut Search for oil leaks and change all hoses Change oil tubes under engine Install hydraulic tensioners Clean injectors Change filters, plugs, gaskets, etc. New exhaust rear muffler and gaskets Rebuild alternator and starter Don't really know what to do to rebuild injection.. .suggestions? Considering my lack of experience on these engines, I will thank any more suggestions from other experienced Pelicans. This car has been parked outside for almost 2 years.... __________________

Parts with the "white" Aluminum corrosion can be bead or soda blasted and then treated with Gibbs protectant to prevent further corrosion.

I understand Madeira is a lovely island. But an island - all that sea salt spray. Don't suppose there is much you can do about that if you drive the car (as, of course you want to and should). Wash it often? Spray off the engine often?
If you can find a small ultrasonic cleaner unit (like women use for jewlery), you can use it to help clean your injectors. Maybe one at a time, depending on how large a one you can buy or use. Whatever is used on jewlery ought to be OK for cleaning these in that way. You can spray carburetor or brake cleaner into the injector, and blow it through with air from a compressor. Will help blow out what the ultrasonic system loosened. But what it also will do is let you see what the spray pattern looks like. Should be a cone of sorts. Easy to compare how they all spray to see if one or some don't look right. Supposedly you can backflush them. Nice to do this, because there is a fine mesh filter in the unit, and you'd want to blow whatever it caught back out the way it came, not deeper into the device. I've never figured out just how to do that, though. Some books say you hold the pintle open with a small screwdriver or something. But if you do that, how do you spray anything? Maybe if you can open it with something, and stick a thin piece of wire in to hold it open? Then put a piece of tight fitting hose over the end, fill with carb cleaner, and spray. Try searching this website, and maybe also the 911 forum, for "clean injector" or something like that. You are not the first to wonder how to do that. Walt |

If you don't have a bead blaster or sand blaster handy, here is an alternative:
 And for the motivation, you can go from this:  To that:

Thank you all for the suggestions.
Considering the fact that I live on an island, salt could be a problem but in fact this is the first time a see this level of corrosion on an engine... I know this car has been parked outside for 2 years but, even with this... Walt Fricke, have you been here? Its not quite common to have Americans visiting us... this is so small that I think you should feel claustrophobic...  Unfortunately, as I said before, I ordered Gibbs products last week and today, when I came to the office i received an e-mail refunding the payment because they don't deliver it to Europe... I will try to find a seller in Europe or a similar product around... Aurelien, great job! The only question I have is: after brushing the hole engine, did you apply some product to protect the aluminum areas?
