***This is a follow up from an old post***
When I first installed my built engine it compression tested:
Day 1- 75-180-80-175
Day 2- 80-180-80-180 (after re-torquing)
The car had ran like garbage... since then I've bled down the lifters, had the head checked out and pieces of alumnium removed from intake valves. Re-installed the head and drove it around, it ran perfect.
Now, I've recently done a compression check @ 400 miles of break-in and got this:
Day 3- 140-180-150-180 (car's idle is a little low, 400-500rpms)
What's alarming about this, is that my coolant overflow bottle is empty (where'd it go?). I never had any overheating problems either. Operating temps fluctuated between 160-175. I pulled my spark plugs and found this:
140(burnt)-180(rich)-150(somewhat burnt)-180(rich)
Cylinders 1 & 3 seem to be so troublesome, what's up with that? I only have 400 miles total on engine.
If my rings were washed out, would those plugs show lean mixtures? To add, I've only seen my car smoke twice for 30 seconds and it was blue'ish. My friends say the valvetrain needs more time to break-in and rings to seat. I'm a little peranoid b'c I've got $10k into this car and don't want to lose it so soon, nor dump A LOT more than I should right now.
Crower springs/retainers, Ferrea SS Valves, OEM lifters, stock cams, ARP head studs, Cometic HP HG, Wiseco 9:1 pistons, Eagle Rods.
Please help
