Hey all, im completely at a loss here, I think i got in at the deep end.. haha. Well it all started yesterday with an oil change with penrite 10w-40 fully synthetic and a z145a (or something along those lines). Started up after that and the car was running on 5 cylinders, number 1 wasnt firing. Thought it was just a connector i had knocked off or something simular. As i was on my way out, i shrugged my shoulders and parked the car. Came out today to diagnose the problem and after running for another 2-3 mins large amounts of smoke and liquid (oil, I believe) come pouring out the exaust. Now im having terrible premontioins of a rebuild after one week of ownership and it has been suggested that maybe oil has gotten into the chambers and thats causing the smoke as i did spill some as i was topping up.. shakey hands i know.. But anyways im a bit to scared to turn the car on untill i have an idea of what to do, any suggestions? car wasnt smoking and was running fine beforehand Thanks for any help in advance
I don't think the car will just stop firing a cyl. Check the injector connector and put a screwdriver to the injector to hear if it?s clicking or not. If not remove the connector and give it a good clean as it?s probably corroded. Either way you?ll have to start it to get a better idea of what?s going on. Also, maybe it had a no smoke additive beforehand?? Good luck, keep us updated Sam
Hah, no 4, 4.1L. Thats what i was told? The injector is clicking, and unplugging the coilpack makes no diffrence to the way the car runs. It may still be the injector, but im pretty sure i could hear it clicking away.
Pull the no.1 plug and see if its coated in oil. I dont know how relevent it is to these engines but if you dump enough oil into the tappet cover quickly it can get down past the valve guides and seals on a engine with a few k's on the clock.
Hmm not right at the moment, ill have to source one, maybe second hand. Im not to sure if its a good idea to run it while its smoking this much.. ahh looks like ill be back to bike riding to work and back for a while! haha
Question You did drain the old oil out first, did'nt you Probs sounds like a silly question but I have seen worse Andy
If he changed filters, then chances are gravity and fluid dynamics are leaning towards oil coming out of the engine My money is on the coilpack getting enough oil on it to cause a misfire. Most likely from filling up the spark plug tube, cam cover gasket leak, or a combination of both.
that wouldn't explain this though would it? Sounds like oils gotten into the chambers and fouled a plug as well as getting burned off
How does oil get into chambers just by being clumsy pouring oil down the oil filler Also, I didn't read anything about coil packs being removed or the an engine miss in OP's initial post Sorry if I've missed something here guys? Sorry but I find it a little difficult to follow the reply posts on this forum. Very disjointed depending who answers what/when. Other forums simply list reply posts 'one after the other' Anyways............. OP. Run car for 10-15mins to burn off the oil that is in the chamber/s. If it stops, as others have said, you could've simply got oil leaked into chamber. Hey Mitch, how would that cuase oil to be burnt in the cylinder? I'm asking as I have a cam cover leak & similar probs as OP. Imo, there's your problem right there buddy Too thin a viscosity for the engine condition/age. Oil going straight past rings? valve seals? turbo seals (if a TT?) Change oil out again, leaving new filter, with 20w or 25/30w oil & see if that stems the smoke out the exhaust An alternative would be to drain a litre out & add an oil viscosity thickener. Get it from Autobarn/Autopro etc. This is what I am doing today to see what the smoke is from mine. I too used the Penrite 10W40, which I stated in one of my previous posts recently. I will report back later this morn with findings..................
It's fine in my car since I changed to it too but I was just considering, if engine is worn & had thicker oil in the past & you change to a very thin oil. It can blow smoke. you don't mean filling to top of dipstick full marker do you? Incidently, mine took more than 4 lts to fill.........
I mentioned pulling the No.1 plug to see if its oil fouled, i had issues (not with this type of engine) where oil had gotten down the valve guides after an oil change due to worn guides/ seals on a very high milage engine . you can fill the tappet cover up if you pour it in fast enough, any way its just a thought click on display modes at the top and choose linear veiw
Under display modes change it to Linear. I have NFI why this is not the default viewing mode for the forum. It is for practically every other forum on the net (besides tt.net). 15-40 is the weight oil I use.
Ill be goimg out to play with it tonight. I did remove a coilpack, as i has determind that was the cylinder that wasnt firing. I checked to see if there was any oil on the pack, didnt remove the plug though. I fail to see how oil could of gotten into the combustion chamber thou? Any ways thanks for all your help, ill reply later on after work to let you know how it all goes.
You can change the forum from "blas from the past 19-****ing-80s threaded" mode back to "how the rest of the world uses forums in the 21st century" mode by going to your control panel and changing the view mode to "linear". No idea why this forum defaults to the other mode but it must confuse the absolute hell out of the majority of people browsing the forum - particularly guests I would imagine.
Any liquid coming out the exhaust will look like oil due to the amount of soot it picks up on it's way. Dip your finger in it and see if it's oil, or water, or fuel (seeing it's not firing). Condensation will start to pool in the tips, I usually get about a 2" wide pool of pitch black water when I start her up after a few days of sitting in winter. If it's oil, then it's not a case of a small amount, as it's got to get all the way to the tail pipes, and your terminology of "pouring" makes me think it's a lot. It won't be a case of some leaked down the valve stem seals while filling. The only time I've seen this is when I melted a ring-land and I now had a massive 5cylinder oil pump under the hood instead of a 6cylinder powerhouse. Take the advice from the other guys, pop off the connectors and spray them with some cleaner in case you spilt some oil over them on the fill. Pull the plug and inspect, flooding an iridium or platinum plug basically screws them, so it may be the issue on the continual misfire and the excess fluid in the exhaust. Hopefully it's just a case of conincidence...trust me, it happens all the time.
No I'm pretty syre oil has to be pumped to the filter and the sump is lower than the oil filter location. so it can happen
