Well here it is rented a brand new cooling system tester from oreaily and it's a REALLY nice unit was $160with tax I would love to have it actually but anyway I put 15 psi on the system as you can see in the picture and it holds.
now if you let it set an set it will go down 1.5-2 psi or so in 10-15min time approx but I consider that holding.
if the compression check and good and this is good yet coolant is still entering the oil does that mean an internal crack to the block or what?
I am fairly techy but by no means an expert rebuilder etc so appreciate any help guys trying to give good trouble shooting info I think with that you guys can help me figure it out and appreciate all the advice so far.
**Will also note I just put the plugs back in after the compression test hand tight with an extension just as a place holder and to keep the plug wires organized so i would think it would have leaked easy right.
