As the “numbers matching” engine cannot be used without mayor block repair, a 2.8 L (call it the Black Pearl because it is black from dirt) was acquired, planned to be pumped up to 3.0 in the first stage. Dismantling of the Pearl turned out to be difficult. The mess started with the heads. When applying my EHE (EPI-Hexadecimal Extractor), which pulled every head up to now, the only thing being pulled where the rocker support studs, which came out with the thread that should hold them down.
Had been thinking of a second generation EHE for some time, so converted the old one to EHE-EVO I.
Consisting of three parts, it now holds the head with the exhaust header studs, the rocker support studs and the intake manifold studs while still pressing on the studs that fix the head to the block.
Several days of making the components, warming up the head in the critical areas several times, and letting some penetrating oil work it´s wonder and the result is . . . nothing. Except for the variety of blown away and bent bolts.
The most spectacular moment was, when the extractor shot four bolt heads off at the same time.
The studs will have to be removed on the milling machine. As its work depth is too small to take up the whole engine plus the tools and the travel they need, the oil pan was removed in order to get the crankshaft out and gain some space.
How surprised I was detecting the reason why the engine was put out of service back in the day. One of the conrods is heavily bent, one other suffers from a bearing failure.
Anybody out there willing to help me out with one (or better one set of) conrod for 2.8L???
Even the spark plugs won´t go without some controlled brutality.
