Hello!
I will try to be brief in describing my problem as I imagine you see several such reports here. I used the search and read several topics with similar issues, but would like to ask an opinion for my particular one.
> New Engine have only 7 miles running.
I rebuild my Eclipse GST 95 engine by myself at home. After the first start, the car began to smoke. I will now quote in topic all the details so you can know.
1 - The cylinders were honed. (Sorry, I don't know the expression.. But is the process that leave some angled scratchs on the cylinder wall.. When... I think you all know what im talking about.
2 - I'm using Wiseco Pistons 9.5:1 (Stroker). I bought new rings. I had never mounted an engine by myself, but I remember taking great care with the correct position of the rings. I remember so far reading the manual, following exactly the position and correct orientation.
3 - Car is smoking at idle (a little), and you can see much smoke when acelerating. (Specially reving at idle or climbing a road.) I will post many pics and videos here.
4 - I used Assembly Lube and WD-40 (Great amounts) in the engine assembly.
5 - I was sad and worried when i saw the car smoking and I decided to remove the exhaust manifold to see what was going on. I noticed that the four holes (the eight small outlets, one for each valve) were very... had spots of some kind of black oil. (You can see on the pics)
6 - Im using E80 (80% Ethanol). This fuel mixture has been in the tank for 4 months. (Fuels in Brazil have VERY BAD quality, btw...)
7 - The turbine has no oil or slack. I didn't find oil inside the exhaust manifold. I also found no oil in the TBI or the pressurization pipes.
8 - The head spent a few months in a workshop. The valves have been changed, the valve guides have been changed, the seals have been changed, the springs have been changed. Preparation work was done on the ducts ... Technically, it is 100%. Also, from the pictures I took, I think the valves are dry (on the stem part)
9 - I'm using a Oil Catch Can. PCV + Side out of the Valve Cover going on the Cam.
10 - The oil level is correct. Top mark in the dipstick. Im Using MOTUL 8100 5W40
11 - In the first start of the engine, I used another Synthetic 5w40 and i changed the oil after 15 minutes of engine working.
12 - Car was running very rich (0.65 lambda) because i was without any tunning. Now its OK. But maybe.. spark plugs are black for this reason. I dont know...
Well.. That's it..
I will post PICS and VIDEOS down here.
You can question me about anything and i will answer here.
Sorry for my bad english =)
