I got one of these last year from EBay. It fits well, looks good, doesn't leak and is solidly made. I am happy with it.

The cast covers are nice in that they don't deform and leak so easily**, they dampen some of the rocker noise, and the look great...that price is probably appropriate. ** ...but if you're on a tight budget, those little force spreaders that are available work well to keep the OE sheetmetal covers from deforming at the screws, allowing leakage.

...the cast covers are quite firm so do not bend like oe sheetmetal ones typically do at the fastener holes, so they do not need the force-spreaders...it is important for the sealing surface to be quite flat, so they squeeze the gasket evenly. Cast covers are usually pretty good right out of the mold, but can be flattened perfectly on a surface plate with abrasive...but you might want to double check flatness by simply holding the cover on head without a gasket, then feeling around for gaps with a feeler guage...I'd expect gasket to have difficulty sealing any nonplanarity which occurs over a short distance. I don't want to give any numbers, because this is a bit of a judgement call...the question is how gradual is any discontinuity over what length, because the gasket can accommodate some variation. Ideally though, the gasket will have it easiest when it is evenly compressed between two perfectly parallel surfaces (which is clearly not the case when the sheetmetal cover is heavily dimpled right at the fastener holes). Cheers from Connecticut! |

"nonplanarity". New word there Ron........
I don't know what the mating surface of this cover is like but they usually don't have any way of retaining the gasket like the pressed ones. The gasket can be glued to the alloy cover with a suitable adhesive. This keeps it from slipping sideways and after curing will remain on the cover for a few cycles of removal if done properly. Can also be done with the tin ones. With both, the surfaces must be 100% grease free when gluing. |
