I have an SVO 302 & after some over enthusiastic revving on a track day, ie 7000 rpm for a *very* short moment (oops!) & hitting 6500 a few times, the engine developed a serious 'clatter'.... doesn't sound like a big end or a main bearing, just a 'clatter'.....
I made the following checks....
visual check of the valve springs - all OK
removed & inspected hydraulic roller lifters - all OK
removed & checked pushrods for straightness - all OK
carried out a leakdown test, all cylinders within 8-12% - all OK
Next I drained the oil & pulled the sump off & found flakes of metal in the oil.... Would anyone care to guess what the problem might be?? I guess I'm gonna have to pull the engine out for a bottom end rebuild, however with the leakdown test showing such good results I'm wondering what the problem might be....???
Any opinions gratefully received!
