Sadly, it seems as if my Guntero has a substantial oil leak. After much dripped oil and a professional diagnosis, it has been determined that the valve seals are gone as well as the gaskets. After 275k + lovely miles, i beleive its time (and have been advised) to do an engine swap.

Which engines are perfectly compatible with my 1995 LS? And what would be the best of these to drop into my Guntero?

Thanks
