510revisited Posted October 11, 2020 Report Share Posted October 11, 2020 (edited) Didnt really come up with a good title. So here goes. I put my 69 2d 510 into a ditch a couple months back. I had just finished doing a zx brake swap, was testing them and merely hit the pedal too hard. Locked em up, lost control and landed in a ditch. Reason I'm typing this now... my boss swung by, took a look at the damage and believes its fixable. IF I had a frame table, and such.. so I jumped into it and started figuring out if the engine still runs, if it drives, so on and so forth.. Now, as a precursor, the car was on its driver side for about an hour or two. Then sat in a garage on all four tires for two months. I fired it up a day or two ago, and she fired right off, but runs like shit. Took it out anyways around my condo complex and she moved.. did the same today, but this time she smoked real bad on cold startup for about 5 mins then more or less cleared, but still runs like shit. By shit, I mean almost like she misfires..... the engine is an l20b, with a holley sniper efi throttle body, and a 123 bluetooth ignition. So basically fuel injected, and a new distributor. My question is why the hell is it running like shit? From oil filling the cylinders while it was on its side? If that even happened.. fouled plugs? sorry it's so long winded, but I'm long winded!! Here is a link to my build thread for those who want more info.. any and all is appreciated. Thanks... Edit: I had to replace both rad hoses cause the battery came loose and broke both hoses. So i replaced them both, refilled the rad. Could it be an air pocket? Edited October 11, 2020 by 510revisited Quote Link to comment
datzenmike Posted October 11, 2020 Report Share Posted October 11, 2020 Sediment in the tank and lines were stirred up. If you have an in line fuel filter change it. Quote Link to comment
510revisited Posted October 12, 2020 Author Report Share Posted October 12, 2020 Tank was removed and flushed. All new brake lines from tank to throttle body.. absolutely no sediment. All new filters. Could it be an air bubble in the cooling system? Quote Link to comment
datzenmike Posted October 12, 2020 Report Share Posted October 12, 2020 Do you have cooling problems? Then no. The cooling system has nothing to do with how it runs other than the temperature. Remove and check/clean the plugs. Oil contamination is a real possibility. Are there any diagnostics for trouble shooting the EFI or ignition??? Quote Link to comment

datzenmike Posted October 12, 2020 Report Share Posted October 12, 2020 I would guess if they hold brake pressure they would hold 50PSI gas. Quote Link to comment

Ranman72 Posted October 13, 2020 Report Share Posted October 13, 2020 check oil and water levels if not already done sitting on its side could have mixed water and oil change both if needed blow out any and all vacuum lines Quote Link to comment
510revisited Posted October 13, 2020 Author Report Share Posted October 13, 2020 Oil and rad levels are ok. I had to replace both rad hoses, so I made sure that was topped off. Checked the oil level before i fired it up, and it was ok, albeit a wee bit low, and dark (pcv issues after the last oil change). I was in the process of removing the plug wires, and managed to ruin one of them. The metal clip stayed on the plug when I removed the wire. I have a set of diy msd wires I'm gonna make up here pretty soon. But before that, I will pull all four plugs and inspect.. On 10/12/2020 at 6:11 AM, datzenmike said: Do you have cooling problems?

510revisited Posted October 13, 2020 Author Report Share Posted October 13, 2020 (edited) Fouled plugs. Took them all out and everyone of them was black. #2 was wet and black. Didnt smell like anything in particular. Not sweet, not gas, not oil. Nothing. Cleaned all 4. Runs LOADS better. Funny thing is the wire I broke was #2. But I never ran it after, which leads me to suspect it was already fd up.. Edited October 13, 2020 by 510revisited 1 Quote Link to comment
