Here are some pics of the top end rebuild that we are doing in my 94 H1. I blew a head gasket over the New Years weekend. These pics were taken with my Hitachi PDA phone, so the quality is only so-so.
After the hood had been removed.
Doghouse and engine cover removed.
Cooling stack removed.
Engine, after accessories were removed.
The top end is off.
The cylinder in the front is the one that was affected (#2). The white specks are remnants of Block Seal that I used to get home.
Close up of right cylinder head (#8). Note the small crack between the valves. However this wasn't the problem...
This is the cylinder where the head gasket leak occurred. The head is corroded away, valves are awful. On the far right you can tell where the gasket failed.
This is one of the new heads I got from
Alabama Cylinderhead.
The right cylinder head is installed. If you ever have to do this yourself, it is MUCH easier to install the exhaust manifold, injectors and glow plugs on the head BEFORE putting the head back on.
Both heads are on and torqued.
I'm replacing the injection pump and many of the accessories as well. I'll post more pics as progress is made.
