Hey everyone,
So this is kind of a update to the other thread, but more to it the reason for separate threads. Anyhow, today I decided to dig into it some more because I sit here at home and watch videos of everyone else racing and I am just sitting here with a car that wont start still.
so for starters, I found oil coming out of the exhaust, turbo inlet, and o2 to downpipe gasket. Im running only a downpipe and it is leaking out of there. I can stick my finger in there and there is a puddle of it in there. It is green in color and I did use lucas assembly lube which is green.
I also found the black particles on the tops of the pistons.
So today I started with a compression test. Last time I tested it all was around 135-140 and I thought that was good due to the rings not being seated and the engine never being started. Well today I get 176-185 across the board. I was excited to see this because I thought maybe the rings went and that's the oil I was seeing in the exhaust.
I then take off the exhaust manifold and turbo. Now remember when I ported and polished my head, I hand polished the runners to a mirror finish 80-1200grit. well they were gunked up with black stuff. The hot side was also black and you can see liquid in there. Same with the manifold. I wiped the stuff off the runners on the head and it comes right off. it smells kind of like gas though??
What is causing this to happen? why would it kind of smell like gas? Also now the tops of the pistons are gunked up with black stuff even more now. I pulled the valve cover and cant really see anything in there that screams a problem.
What should I be looking for? Would this stuff be the cause to why my car isn't starting?
I also took off the COP set up and the dyna tek for now until we can figure this out. Please let me know what you think and what do I need to be looking at, what should I be testing, what things do I need to do to fix these problems??
Thanks in advance and god bless you all,
Anthony B.
