7MGTE: Running after accident but still burning oil

[RObErT_RaTh]

Hi guys and gals,

As some of you may already know I unfortunately rolled my 7MGTE MA61 onto it's roof. I'm now in the process of trying to get the engine running properly so it can go into another MA61 I have but I need your help please.

When it comes to engines I don't know sqwat so please assume you're talking to level one noobie that doesn't know all the acronyms

The story is, immediately after I rolled the car (still upside down) the engine had already stalled but I turned off the ignition. I was told later by the police that the car was leaking fuel and I was lucky there wasn't a fire or anything. Just after the crash I could smell fuel but didn't really have time to investigate where it was coming from.

I now have the car back home, in the carport up on stands and after about 2 months now since the accident I thought I'd try and fire it up. I did my best to have a look around for any broken or split lines leaking fuel etc but I couldn't spot anything. Then again I'm not entirely 100% what I should be looking at anyway. I went to start it and after a surprisingly short amount of time it turned over and spluttered into life! It seems to be running extremely rich, lots of smoke and really strong smell of fuel. It didn't run long before it died, out of petrol, oopsie

I put some more fuel in and it then took a lot more time and effort to splutter it back into life again, had to have it jump started. Let it run an idle for about 10 minutes and it was keeping fairly constant revs and slowly revs went down as it warmed up, guess the ISCV was doing it's job, but it was still running rich as all hell and when I tried to rev it a bit it just smoked up the place so bad and stunk of fuel so bad.

Looking in the engine bay there was also a small amount of smoke coming out from the side and off the top of the engine and I don't know what would be causing this? Also could still be fuel coming out from somewhere? And with the car running so so rich is it quite likely I've had a sensor or something come loose and need to check plugs on certain systems?

If anyone has any specific ideas on a sequence of checks I can do and how to do them that would be great as I'd love to get the engine running smoothly again. I'm not in any kind of rush but I'd like to get the engine running smoothly in the wreck before I take it out to put in another car. No point doing the conversion if the engine won't work properly.

Thanks in advance and +rep will be given for sure

mate im in radelaide from the 12th of october, i can have a look with you if you want?

Are you sure it was fuel smoke (black) and not oil smoke (bluish-white)? I would expect tons of oil smoke after an engine was upside down, heaps of it would have found its way into the combustion chambers. It will burn off eventually.

^^ oil is going to be LOTS of places it's not meant to be. With smoke coming out of the side of the engine, that could be oil that's leaked out of the filler/dipstick after it got turned upside down, and has found its way onto something that gets hot, or it could be a cracked breather hose/fitting, cracked exh manifold (if it takes a while to start smoking from the engine, it's something getting hot then burning leaked oil. if it's immediate, look at mani)

Dude that might be handy if I can't figure out what's going on before then, thanks a lot dude Would probably be the weekend after the 12th or something when I'd have time if you're here that long?

Well it didn't look like it had any tinge of blue to me and seemed more grey to be honest, wasn't thick dark black smoke but wasn't really blue or white either. Perhaps I should try and get a video and see if the quality is any good for you guys to tell. And when you say it'll burn off eventually, how long do you think that would be maybe? Should I try and start it up again and just let it idle for another 15 mins tommorow or something? And it does have thermo fans that are still working (atleast they started running after I turned off the car) so it shouldn't overheat sitting there idling.

Oh I'm a bit sad about the oil now, gravity is a bitch And don't think it leaked out the dipstick as that hasn't got any signs of oil dripping out of it when I grabbed it and looked over it. Also the dipstick was never re-located in the conversion if that makes a difference? My neighbour also suggested cracked exhaust manifold too or atleast moved enough to cause a leak with the gasket. I'll have to check the engine bay next time I start it up to see if smoke comes out straight away or a bit after. The engine wasn't clean by any means before I had the accident (grease and crap everywhere) and if fuel was leaking onto things could this sort of cover parts that get hot and mix with the grease and junk and now I've turned it on it's heated up and all these parts are getting hot and it's sort of smoking and burning off?

i fly out for china on the 17th, so has to be that week some time, im free every day as im just fixing up my house.

Well you might not have to come around as it's looking better already I think.

I just went out again, thought I recorded 2x videos but only recorded one, fark! (using sisters phone, unfamiliar )

It started up straight away but was sort of spluttering and really low revs, around 500 mark just barely staying running. There was a small amount of immediate smoke noticed coming up from the engine so I've got an exhaust leak somewhere then? It also wasn't putting out anywhere near as much smoke out the exhaust but I assume that's because the revs were so low? Just seemed to be partially black smoke. I tried to apply the slightest amount of throttle and it just died.

I moved a couple random plugs around, disconnected and re-connected the AFM plug and made sure it was on ok (doesn't clip properly though so just pushed it tight) and then I started it up again. It ran a lot better, first revs were around maybe 1400 but came down fairly quick to about 1100. Still seemed to be running a bit rich and maybe burning off a bit of oil and blowing some smoke, not overly blue or overly black but very faint amount of each. It revved better and when I gave it a bit of a squirt to just over 3000 it revved up okay but multi backfire as soon as I let off. It did this a couple times. I let it idle for awhile more, idling smoothly under 1000 but was still blowing smoke. I didn't want to keep it on for ages as it was about to run out of fuel again so I might run it again tommorow for 10 mins or something. Messing with the random plugs really seems to have helped it's idle a million times.

After I turned it off I tried having a closer look around the exhaust and I noticed something missing Coming off the top of the dump pipe is a sensor (this the O2 sensor???) and it has a diamond shape flange with a bolt on each end and it's missing the head of one of the bolts It's weird though because I still think it's leaking exhaust from somewhere else more directly on the side of the engine or kinda closer to the front of the engine because that's where it seemed the smoke was coming from.

[Kedderz]

I'll ask at work next week when my manager gets back, cheers again dude

[deaf_rattle]

you are doin it all wrong.. you need to put it in the other car. thats your problem!

hope you get it sorted alright dude.

Lol, if I put it in the other car then I'm stuck with 2x MA61's that don't move I'm thinking about even trying to degrease the engine bay and borrow a mates steam cleaner or something and then see if that can get rid of stuff that might be covering parts and burning off?

just go over everything in the bay man, and replace everything thats easily done.

shit like oil and filter isnt necessary, but id do it anyway, plugs, check ya timing etc.

its obviously not burning fuel, so look att he ignitino side.

anything from blocked injectors (from shit in the tank + running out of fuel) to fouled up spark plugs, not to mention leaks post-AFM etc.

i remember with my supra, when i had leaks after the AFM, the thing used to chug and bitch, it took ages to find the leaks cause they were splits in rubber hoses, and only opened up when the pipe was check thoroughly.

Well I did an oil change not long before the acco and mobil 1 aint cheap, was like $80 just for the oil Just for trouble shooting and running the engine a bit inside the wreck I could get away with using a cheaper oil but still something 10W-30?

Plugs I'll try and swap, and I don't have a timing light but I've always thought about getting one and there is a repco literally next door to where I work so I'll pick some stuff up next week and see how it goes. And I'm really hoping it's not a leak after the AFM because ma61turbo spent a bit of cash buying a genuine toyota replacement pipe that goes on between the AFM and turbo not long before I bought it off him.
