[DeTomaso] leaking mystery

[Christopher Kimball]

Thanks--maybe I'll end up taking out my engine sooner than I had planned.

Sincerely,

Chris

I found the exhaust valves to be very loose in the guides so I decided to pull the heads. What I found was that the intake seals had shifted around and created massive vacuum leaks from the lifter gallery. The result was oil buildup on both intake and exhaust valves, on the exhaust valve stems to the point where the guide inserts had been worn away to zero thickness. When I tried to put an old valve in a fresh guide the valve stopped about half an inch from the valve seat.
