I gave up on the 350 dollar 1.7 that i tried putting into my car, so now im tearing into a 2.0 i bought a while back. The guy i bought it from said that he had it rebuilt about 10 years ago and then was never able to get it to fire up. Anyways, he told me that it had hydraulic lifters in it, but he didnt know much else.
What i am wondering is how to tell the difference between a hydraulic cam and a solid lift cam. There are hydraulic lifters in the engine. Im tearing into this engine and trying to make sure everything is legit in it, but now that im almost completly disasimbled, im thinking about a 2056 kit for some reason. The engine looks pretty good inside. The rings look brand new, the cylinder walls look like they were honed a few hundred miles ago, the cam looks new, the pistons look old and one has a big ding in the top. A few of the cylinders have fins broken on the top. Looks like the engine was "freshend up" with not much money being spent. Im not sure if i should put it back together and try it out, or if i should just drop some cash and put together a really good engine. |

No GA motor had a hydraulic cam stock. So if that IS a hydraulic cam, someone did something really odd with that motor. Len Hoffman (HAM, Inc) is pretty good at spotting things from a picture (if you post bigger versions). That's probably your best bet.
The chambers don't look like they've been flycut, which is bad and often skipped by non-reputable shops. Other common 'fixes' by non-reputable shops; grinding the valves and seats instead of replacing them, reusing worn out valve springs, reusing sodium filled exhaust valves, etc. Unfortunately, our heads are so touchy that you either spend some serious $ doing it right, or you slap it together and hope for the best. Mixing the two is a recipe for wasting $. |
