When buying a used engine from a scrap yard, there are always going to be concerns and you’re bound to run into some issues. Today, the folks over at ASI ran the leakdown test on the K24 and had some not-so-great results… Cylinder 1 looks good, but 2 and 3 are terrible and 4 is just okay.
– Cyl 1: 87/90
– Cyl 2: 50/90
– Cyl 3: 30/90
– Cyl 4: 80/90
Next steps now are to inspect the head. If we’re lucky, it’s just a little bit of carbon build up and/or the valve lash needs to be adjusted. Worst case scenario would be a burnt or damaged valve or seat, which would require additional machining/parts replacement. Fingers crossed on the next set of results, but even under the worst case scenario I wouldn’t be too disappointed with having a freshly built head.
Here are some pictures. As you can see, the exhaust manifold is off and all of the plastic shields have been removed.
