Hey Guys,
I'm gettin a compression test done tomorrow, but I want some opinions on whether or not I could have damaged my engine...
It's a brand new block from the race shop, bored to 85.5mm with ross pistons and rings.
The engine has accumulated just 50 miles and about 3 hours of running time sofar but I want some input if that's enough to do damage or not, so...
First, my engine coolant temp sensor was miswired from previous owner, forcing the ECU to think it was -40 degrees outside and dump ungodly amounts of fuel into the engine. Some driving, mostly idling, was done in this condition. Second, fooling with the VPC/2gMAF and running MAFless also forced the engine into running under rich conditions. The significant part of the 50 miles sofar was done messing with the VPC/2gMAF/MAFless and she was super jumpy/fuel cut like symptoms.
There was gas in my oil, enough to make the oil drip freely like water ratherthan like oil from the dip stick. I changed the oil, ran for 15 minutes, then chaned the oil again. I plan on doing another oil change this weekend.
No blue smoke (oil) has come out of the tailpipe, just transparant black (gas smelling) smoke
Should I be worried about my piston rings? Once again, they are new and Ross.
And is there any other tests I should be doing to determine engine damage besides a compression test?
Thanks guy!
