6 bolt 4g63 in 2g Eclipse GSX cylinder head removed in under 10 mins
Removing the head of a 4G63 in 10x speed.
The project got delayed a few months. After finishing it and cranking it
over, Interference in the cylinder was discovered. Shamefully, I admit my
mistakes were: 1) Not putting the spark plugs in immediately after
installing the head. 2) The bad habit of using my Valve Cover as a parts
tray and 3) Putting off the project too long, so I didn't recognize a
missing bolt from a custom fabrication.
The head needed new valve seats, valves and some welding. Wiseco and the
machinist both thought I'd be OK running the piston after smoothing out hot
spots, but I ordered a new piston not wanting to risk the deep gouge in it
with the high Boost I plan to run.
Peace of mind is priceless.
The danger in being over confident is sometimes you skip triple checking
stuff. I've built that engine at least 5 times and got careless.
