Is my engine dead? lol

[Boss 351]

My engine always took a little oil and knocked at around 4000rpm, that was last year. Now, however, is a different story. It's as if the engine runs on 7 cylinders from 1000 to 2500 rpm. It smokes so much oil that if I floor it, the cars behind me end up in thick oil fog. It also drinks a lot of coolant too lol...

I checked all my spark plugs, all are fine except piston #7 which is full of oil and coolant (thick black junk and soft white/grey deposits). I also have some oil in my coolant. So I did a compression test here are the results:

1 - 140
2 - 135
3 - 133
4 - 130
5 - 135
6 - 136
7 - 120 (this is the one with oil and coolant sparkplug)
8 - 132

So it's time for a new short block, despite this handicap, I can still beat ricers at stop lights I have most of the stuff to build a 347 so it's not a bad thing my stock original engine is about to drop dead.

oh and it will drink 2 cups of coolant every other day and require 2 liters of oil also lol... I'm looking for a good short block to just dump into my car and I'll use the stock engine to build my 347 on the side...

sounds like it may have a blow head gasket.

2 liters of oil in two days....good god man

was that knock predetonation?

 

[Boss 351]

no it's a knock, I think it's a wrist pin knocking. But it will ping if I take off in 2nd gear, I've never heard it ping last year.
