Well I had an RC injector stick open on me yesterday driving to the shop.
#1 Cylinder, 720cc of un-regulated fuel going into the motor, and out the exhaust port of the head and into the oil.

Pulled the turbo/mani/dp last night, injectors out, and cranked the car over just shooting gas out of the cylinder. Got most of it out, let it dry out over night with no plugs in, and waiting for today so I could pick up a set of FIC 850cc injectors from a friend.

Tonight I put in the new FIC 850cc injectors, put the car back together and fired it up. Misses hard, sounds like a subaru actually. Pull the plugwire on the #1 cylinder the tone doesn't change. Check every other cylinder and the tone changes drastically. Didn't get a chance to compression test it as the tester is pretty jacked up.

I will leak down test and compression test the motor asap.

Anyways, I am pretty sure that the #1 cylinder is washed out being the oil has a rather "stiff" gassy smell to it. Tomorrow I am going to change the oil and put some new plugs in it, as well as trying to get some wd40 down into that cylinder to "try" and bring it back to life.

Has anyone else ever run into this problem and/or been able to correct this problem without tearing the motor down? If I do need to tear it down will I be able to get away with just honing the cylinders and putting new rings in (assuming they are not scored) or does more damage usually occur?

TIA for any assistance. Tryin to keep things positive, our season starts in about 2 weeks.

 

sorry to hear that this happened. were they RC 720cc saturated injectors?

When I recieved my motor it was full of stale gas and all cly were completely washed out with zero compression. I put a cap full of auto tranny fluid in the cly, let it sit and cranked over the car without the plug. Then after it has time to sit some more start it and let it run. It will burn off the tranny fluid and smoke white for a while. I just drove it like I was breaking in the rings for a few miles and it has been fine since over 20k miles ago.

 

Thanks for the tip. Anyone else have any more input?

*edit* They were RC Peak/Hold injectors.

 

Bump. Any other ideas?

Very interesting. Can anyone confirm that this works?

 

why does this happen? How can it hurt a motor?

 

i washed all mine when i first did my install. 450cc inj and i didn't lean them enough. blew out each cyl w/ compressor and let air out w/o plugs overnight and then dripped tablespoon or 2 worth of oil down on each piston top and let it coat the piston and cyl walls to regain compression. worked like a charm...just smoked like a b#tch for about 3-5 minutes as it burned off. that was 18k miles ago at 11psi. just do it quick and don't keep running it until you get it fixed. def change your oil because you have a lot of gas in it now.

I've heard it from a few techs at work also. The detergent in the ATF cleans the cly walls and rings a little better than regular oil will, but basicly the same concept.
