Hi all, just thought I’d start a thread on my build (outside of my introductory thread).
I’ve currently got a 99 G203 with the usual symptoms. HE-E is leaking from almost every gasket possible, blowing smoke everywhere. Currently starts, runs and drives fine, but will settle on a 200RPM idle.
I was gearing up to pull the HE-E and have it rebuilt, but then I came across a HD-E from an Applause with 116,000km. Upon first inspection, everything looked fine except for a small hairline crack around one of the transmission dow pins. I was also told that the valve seals might be on their way out, as there was a small amount of smoke at all revs. I pulled the pin and decided to run with it. It was certainly healthier and more youthful than my current option.
Whilst leaving the HE-E in the G203 for now, I’ve begun pulling the HD-E apart for inspection… Oh boy…
Things that need addressing:
- corrosion in the coolant passages has eaten away at the head and will require welding and grinding to fix.
- 4 of the 16 valves need replacement
- valve cover is cracked - Was going to swap the HE-E on anyway
- thermostat housing needs welding to fill the cavernous hole caused by erosion
I’ve not spent too much time on the bottom end, but the top end has since been sent for welding, pressure testing, grinding etc etc.
Though I initially just wanted to be able to swap a healthier power plant into the G203 and go, I’m excited to spend a bit more time (and much more $$) to make this HD-E the best it can be.
I’ll post a few more photos once I receive the head back from the shop, but for now, enjoy a couple shots of the “before” (head corrosion + thermostat corrosion)
Stay tuned!
