I’ll try to answer everyone’s questions comments.
Craig, there was no evidence of anything amiss prior to yesterday. Coventry West rebuilt the head earlier this year and I installed it in late March and probably have about 500 miles on it since then. Oil pressure was always 40+ at startup and 20+ at idle hot, always 40 at 3,000 RPMK regardless of temp. No hint of a problem until yesterday. My only notice of a problem was dropping oil pressure going to zero within a few blocks of home. No noise, no clacking or other expensive noises.
Miles on the engine? Who knows it’s a 48 year old car with a 5 digit odometer and who knows how many previous owners. 55,540? 155,540? Service prior to my ownership? Again, who knows.
Patrick, I considered and rejected going in and replacing some bearings and the oil pump. Too many unknowns would be left unaddressed. As Nick alludes to who knows what, for example, lurks in that crankshaft.
Carl, the residue is copper with probably some babbitt material thrown in for good measure.
Lloyd. Compression used to be fine, I can’t recall what the readings were though.
Our intent has always been to actually use this car. Take trips, pretend leaded premium fuel still exists and is 35 cents a gallon. That’s all a lot more fun if we don’t have to worry about “what’s going to break next”. Peace of mind on the road is worth a great deal.
Instead of a problem I see this as an opportunity to walk away with what is essentially a new engine, properly done. I’ll leave the transmission attached and have it checked and at the least have new front and rear seals installed. If the experts think it needs a rebuild I’ll have that done as well. The Boss fully sanctions this approach so that’s pretty much settled. I should strike while the iron is hot.
I’ve got a pallet in the green house and I was having two new tires put on the truck so I’ll keep one of the takeoffs for the engine cushion. That sounds like the best way to transport thing to the shop. Thanks for that tip, Ole.
