At 230,000 miles I decided to finally park the 87 300D when the amount of combustion gas escaping into the cooling system got so bad that I could hear the coolant bottle burp every minute at idle. I spent the last few months rebuilding a #17 head, injectors. Then a couple weeks ago I came across a 603.971 engine in the JY from which I took the 55 trim turbo, exhaust manifold and all the related components. Finally this week I rebuilt the 55 trim turbo and pulled the head.
Here's a video of the #14 head immediately after a cold start.

Behold the #14 head in all its glory.
