70-914-6 Clean Up, Focusing on Cleaning Engine Bay Options

[ctc911ctc]

1970, 914-6, 93K miles - excellent shape, very minor rust

I will post to this thread occasionally as I move through this project, I have asked for guidance and received many good thoughts from this team - thank you 914World

I am in the midst of removing the engine and transmission. All original. There is oil everywhere, not flowing but seeping - seems that the valve covers are not tightened or have loosened with age. Here are the first pics:

On the rack - hopefully not for long:



Shift Assembly is very clean, no wear, bushings are in good shape but all of them will be replaced







Heat exchangers have no holes in the pipes that I could find, the surrounding tin has been treated with anti-rust leakage - perhaps this was the plan in Stuttgart?







No plans to change the exhaust system - any guidance as to cleaning or preservation?

All comments and guidance appreciated - engine coming down on Friday

*******UPDATE*********

Cleaning up the engine,

The engine Bay and other parts

I was able to get a smaller power-spray handle so I could get into the engine bay with the spray handle.



I am trying to understand if this car was coated by 'Zeibart' or similar, some of the crud in the engine bay was grease and grime, however, on the underside and wheel wells, there is a very tough material that seems like oil and gravel, however, it comes off in sheets in some places and will not come off in others.





Does anyone else have experience with this type of undercoating?

Also, this is as clean as I am going to get the engine bay - will wax/buff it next





Here is the engine ready to go into the engine bay
