Well I just built this engine not to long ago, it is a sleeved h22 cp pistons h beam rods etc. I am having some trouble, I am getting gas somehow in the crankcase, the only thing I can figure is since I haven't even broke it in yet, the gas is leaking down into the crank case past the piston rings??? Is this normal? Well anyways my fuel setup consist of id2000 injectors on a golden eagle rail, the feed like is -an 08 and the return line is -an 06 I am running 43.5 base fuel pressure and I have 2 walbro 255 in the tank running in a parallel feed setup. The only thing I can figure is what I said above, however I could just be running stupidly rich at idle any help would be great or suggestions as well...also I cannot get the car to idle by itself it will spit and sputter till around 3k rpm... I'm lost at this point I don't want to start and run the car and blow it up b/c the gas has thinned out the oil in the pan, and thus I cannot break it in...

What is it tuned on? I take it you don't have a wideband installed or easy access to one. A fuel pressure gauge will help make sure you are running the right psi as well.

I haven't had it tuned yet, I have a aem wideband and it will be installed later today when i get off work. I am using hondata s300 I have a fuel pressure gauge I am running 43.5 psi of fuel pressure. I am going to get it tuned as soon as i figure this issue out so i don't waiste time at the dyno.

I hope that engine is being turbo'd otherwise that is wayyyyyy tooo much fuel for NA

patroick67

Yes I'm using a 6765 dual ball bearing turbo shooting for around 700-750 after I fix all these small problems

Also I just did a compression test it came back at 170 on all four cylinders, it is 9:1 compression pistons so that sounds about right... The only thing I don't get is the oil is creamy like it would have coolant in it but it smells like straight up e85 and it doesn't smell like coolant at all. anyone? any ideas? help!!??

Enzo15

Sounds like its waaaayyyy tooo rich at all times

patroick67

yeah i am thinking that it is just way to rich as well, I was curious as to what e85 and oil mixed together looked like so I mixed some together it looks exactly like coolant in your oil lol well at least I know it isn't coolant that got down there somehow just gas that leaked down the cylinder walls since it is a new motor, well I am going to let the engine drain for the weekend to get all that nasty oil out of it and then change the oil again and give it another shot and see what it does. I changed it again last night and it was much cleaner than the first change, I also have my wideband in the car now so hopefully that will tell me some stuff as well. Fingers crossed but it looks like my retarded self flood the **** out of it and it got into the crank case.

Given the problems you have getting it to idle, it sounds reasonable that you are just dumping fuel. The bad news is that means you were totally washing out the cylinder walls and the rings probably didn't seat well. How much have you run the motor? I would avoid running it much more until you can figure out the problem so you have a shot at still seating the rings.

Are you setting the FPR with the vacuum hose disconnected? If the hose is still disconnected you are setting the pressure too high; you have to have the hose disconnected to set your base fuel pressure. I'm also assuming that you have the injectors set in the s300; if you haven't touched it at all you are dumping about 7x the fuel you need and is surprising you can get it to start at all.

Well I have set the injectors in hondata s300 but i didn't set the base fuel pressure with the hose off, I will do that tonight when I get off work I was unaware that that made difference. Even when I do set the injectors in hondata s300 I can't really get any difference. This is what I did in the injector size table I would set it to 2000cc injectors for the id2000's. Is this wrong? Or should I set the injectors to a smaller size? Also is there anything else I should set as far as fuel? I was reading something about the deadtime was difference on these injectors? lol sorry for all the questions. I just want it to get it to idle so I can make sure everything is okay so I can take it to get it tuned.

patroick67

and yes before anyone says it I am basically a hondata noob

gstrudler

Reset the FPR and see how it runs. I'm not familiar with Hondata, but I would double check the manual and online to make sure you are setting it up correctly. Yes, the latency will be different for every injector, so to set it up properly you would want to correct for that, but your tuner should be able to do it, and shouldn't cause the symptoms you see.

thanks well I did more diagnostics and it was coolant in the crankcase actually, I just don't know how it is getting there. I did a compression test and had 170 on all 4 cylinders, I did a leak down test and that was good, and tomorrow I am going to pressurize the coolant system and see if I can visually see any leaks anywhere. I did have the iac hooked up backwards but I don't know if that could cause coolant to get into the crank case well I guess I try and figure it out tomorrow.

patroick67

Problem solved had my coolant lines on the iacv hooked up backwards I guess this was somehow allowing coolant into the oil? But this was solved after I looked at my prelude and realized they were hooked up backwards. This also solved pretty much every idle/ flooding issue I had as well...now I'm just curious as to how having the coolant lines reversed on my engine could cause this anyone? I'm all ears for an answer.
