Happy Valentine's Day to me!

 

To me that perfectly explains why your engine is full of carbon.

If your running a mini battery have a back up then change it out when the one in the Evo gets weak. Mini batteries can be rebuilt cheaply.

When you idle any car from a cold start for a extended period of time it puts fuel into the engine oil(bad). This issue gets worse when you have high flow injectors dumping fuel into the engine. The fuel being supplied never fully combusts and just slides past the piston into the oil pan. So when the car is idling your washing your cylinder walls with fuel.

Here is the logic behind this: its mainly because of air flow. The more air that is flowing through the cylinder head the better the fuel can mix and the resulting explosions produce more power. Idling has the least amount of air flow and so the fuel is just mixing a little bit.

 

But driving right after startup when its really cold out is not good for the car either. I usually let my car idle for a while since it gets really cold here.

 

Deylag - I appreciate the input. However, I have a hard time believing that a few combined hours of idling at operating temperature caused this. I have spoken to some other people and they seem to think it's normal for an engine with my mileage running 93. I may call EvoDynamics and see what Kevin has to say about it. Regardless, what's the best way to go about removing this stuff? I don't want to try remove it as is sits and have particulate stuck between my cylinder walls and pistons. I'm thinking I may put it all back together and try some additives to break it up later. Back in my DSM days people used Mopar Combustion Chamber Cleaner but it was hard to find 10 years ago. What are people using now?

 

I may still have a can of MCCC. Iced some to clean parts when I rebuilt. Want it?

 

Aggie - I may have to take that off your hands. Props to you for having MCCC.

Got to work hogging out the 9.8cm turbine housing. I still need to sand everything smooth but it's matched to the gasket now.

 

you can also try seaforming the car but , since the engine is a part don't think it will make such sense lol

 

I sea foamed the neighborhood before. Stp makes something similar.

I don't think the carbon hurts anything does it?

 

I don't believe it actually hurts anything but I'm guessing it could potentially cause hot spots that lead to detonation. Hopefully someone more knowledgeable than myself will chime in.

 

haha. Havent done it with the evo, but Ive smoked out the whole neighborhood with both of my jeeps. The neighbors love it.

 

Finished up the hotside and put new seals into my throttle body. Hopefully I'll be able to plug the EGR port in the head, get the head on, and the IM/EM/turbo this afternoon.

 

Got the last of my engine parts in from STM today.

Gates timing belt
Gates tensioner
Gates Micro-V accessory belt
STM TB seals because I tore one of my Works while installing the TB shaft
OEM throwout bearing
Mishimoto magnetic drain plug
Oil return line to oil pan gasket
Energy suspension mustache/diff bushings

Also bought a used buschur 3" DP, Cobb test pipe, and Cobb catback so I can meet SCCA rules. Thanks, Dynotech Tuning!

So much to install, break in, and tune with so little time before the March 29/30 National Tour event with SCCA. I foresee many late nights and long weekends.

 

Not much to update on. Head's back on and torqued, decided to buy some GSC S1 cams today so now I'm waiting on those to get here so I can put the motor/trans together and into the car. I've accepted I won't make the National Tour event but oh well. I don't really want to get in a rush and start taking lazy shortcuts. This is how she sits...

 

It took a couple of weeks to get the cams, but they are now installed. Painted the valve cover yesterday and had a buddy help me set timing at lunch today. Going to button up the timing area and get to work putting the trans back on and both into the car again.

 

So I finally found some motivation and a helper to put the block/trans together and drop it in. It's been a busy weekend since then. The front suspension/brakes are back on and other than torquing the axle nuts it's ready to go back on the ground from that standpoint. I put a ~0.125" thick washer under the Whiteline KCA-400M Offset Caster bushing and it ended up not hitting anywhere on the subframe or control arm. I was pretty happy about that. I still need to lengthen the starter/alt/battery harness so it reaches my mini-battery while going under my IC pipe. Once that's done I can install it and put her on the ground. I'll work on the wiring harness and the tuck this week and hopefully have the rear in the air and parts coming off it this weekend. Some pictures for fun...
