Sr Problem

[awsomesr20det]

Ok so here is my problem, from the begining. I have a 92 240 with an red top sr. Well two weeks ago, I did the oil change and used mobile one synthetic. I have been using synthetic for a while now, but when I did it this time, (yeah me and my dumb ***) overfilled it by about a quart. I did this being stupid, i put some type of additive in there to help lubricate things better and thats pretty much almost did the over fill. Well after that, I started smoking BAD . So I took it to my buddy at the shop and we drained it a bit and got it pretty much down to where it needs to be. Tried to burn it off a lot, and still smoking. I went the yesterday and drained it some more and put some thick oil stuff in there, supposed to help stop the smoking you know. Still is smoking a bit though, do I just have to let it keep smoking till it all burns off? I mean we checked the plugs and they looked great, Turbo sounds like it is running fine (i have the gt2871R). I just want it to stop smoking!! I mean I don't even smoke and if I did, i don't think I could smoke as much as my car. Help??

sounds like when you overfilled it you caused an unusual problem. high oil pressure. high oil pressure can blow seals and gaskets. the blue smoke means your burning oil. you might have blown your head gasket.

hope this helps.

Excess oil pressure can destroy seals but if the headgasket was toast you would have alot more issues like overheating, white smoke, poor preformance (not always). Still do a compression test anyways to make sure you're HG and piston rings are fine and if thats good have I would personaly have an engine flush preformed to get rid of all the oil then refill the car to spec with the normal oil you use.

Ok so I have a 92 240 with a red sr (as some of you may know from my other post). Anyways, Comming across that Blue smoke thread, I wanted to post about something about it. I took it to my friend at his shop, and not that I don't trust him, I just wanted some more opions on the problem. See now from a Mech at his shop said it could be backing up into the torbo (why does he say this?), Well he came to this conclusion. Simple fact that I first over filled it was just quincedence, but the oil return line on it is a heater hose and is soft, and and it is easily able to collapse. So we think that since it can do this, that when it heats up, it is collapsing in and not allowing the oil to return to the engine their for coming back into the turbo and blowing out the exhaust seals. Whats your all's opions? I mean we are going to change the hose this weekend of course, but opions are always great!

He so if anybody reads this, OMG it was such a simple fix. Took it up to my buddy's shop, and had him replace the oil return line from the turbo. The original one was kinked and worpped!!! so now the Oil is flowing like it should!
