Need Help With My Suv

Happy26 · March 19, 2014

HELLO GUYS,

here are the problems im having with my suv.

1. vehicle pulling power has gone down

2. fuel consumption is pretty high, 6-7 km per Lt in colombo city limits with ac on

3. i used to top up engine oil once every 2-3 months and been recently im having to top up twice every month (i've been told engine oil is burning in grand scale)

4. And very recently when i was driving,... engine started to miss fire out of no where, and when i took the vehicle for a scan and for a fix the mechanic found out there's oil on 3 out of the 4 spark plugs so they said,... oil is leaking into the plugs so it has to be fixed 1st before fixing the misfire.

5. When i last started the vehicle, there was lot of black smoke comming out the silencer, i did a plug clean up and managed to run for couple of days and now it won't even start

one of my freind said, if there's a oil leak i should try using a STP oil additive along with engine oil and it would fix engine oil leaking into the plugs temp.

aother freind told i should do a engine compression check to see the condition of the engine, pistons etc. but to do so i have to get this thing started, so im thinking the STP "engine stop leak" solution or the STP "SMOKE TREATMENT" would help me out to start my suv and take it to a garage at least.

looking fwd for your valuble input

Dude, what is the model of the SUV i guess that will help

From the look sof it your valve seals are gone, STP will be a temporary solution

To address your immediate problem of starting the SUV you would have to clean/replace the plugs. Once started keep it on idle (do not rev up) until the engine warms up and then drive off. If it is only a few km to the garage then you should be able to make it. You have not given the model/year etc of your SUV but according to the given details you should have addressed this issue sometime back. Waiting for the ECO test to fall due before taking action is not the right way to maintain a vehicle. In fact when oil burns it gives out white smoke not black. Did you not get a check engine indication (CEL) every now and then? In addition to obvious compression leak your O2 sensor/s may have got busted by now. When you repair the engine make it a point to inspect them and replace (or try a do-or-die clean up) them if needed. If you were running the SUV like this for sometime chances are that your catalytic converter could be in bad shape too. I would be very surprised if you did not get a CEL indication.

I did a clean up again and it lasted for abt 10 mins only and didn't start again after that. It seems oil is leaking into the plugs ; /

True, because i belive having to top up engine oil once every 2-3 months is not normal

I never failed any of the eco tests so far, all this mumbo jumbo started to unvail very recently

It never smoked before even though there was a small internal oil leak (into plugs) and a oil burning issue. i saw the smoke comiing out very recently.

I sure did, but there wasn't anything serious, until recently i got an engine miss fire. And i did a scan, and that'S when i found out there's an issue with the O2 sensor and fuel pressure pump, so the electrician guy replaced the O2 sensor 1st and after a week or so i went back to fix the fuel pressure pump issue which is causing the engine miss fire, so that's when i found out, oil is leaking into plugs. and they said engine miss cannot be fixed while oil is leaking into plugs and ask me to take it to a engine specialist.

There are several STP engine oil additives available, http://www.stp.com/products/oil-additives/ u have any idea which one i should use to get this thing started ?

Happy26 · March 20, 2014

and oh bdw, i showed this to 3 different mechanic's and the 1st one said i need to do a complete engine overhaul and replaced the pistons, rings, gaskette, oil seals etc. and the 2nd guy said i should get the genuine rings from agents and that would fix the issue. and the 3rd guy said something completely different, he said i should replace the fuel pressure pump (non of these mechanics dismantled the engine nor removed the head at least to diagnose the real issue i have no idea whose right and whose wrong and what exactly is the issue and where to start

Does your car have a turbo? If it does it could be the turbo spitting oil into the intake manifold due to worn out seals.

If it does not have a turbo, at the very least you will have to replace piston rings, and valve seals (a partial rebuild of the engine) plus replace all gaskets.

So you got a CEL indication but did not consider it a serious issue right? Then ur O2 sensor got busted and even the cat converter could be clogged up. Now aren't these serious issues? Mind you when you have a CEL indication it is bl@@dy serious. Of course you can continue to run with the indication in majority of cases because that's how the system is designed so as to prevent you from being stranded. But that does not mean you can continue to run and expect the vehicle to behave normal. If the plugs get soiled in 10 minutes it is a very serious oil leak somewhere and if I were u, I would rather tow the SUV to a garage.

You will see the turbo connected to the line that comes out of the exhaust manifold. and the turbo will have another line that runs into the intake manifold. In this scenario you will find oil inside the intake manifold.

As Rumesh said, kindly stop driving the car and get the issue fixed before you have to spend even more money fixing it!

Yeahh that would be the last option. Towing is bloody expensive so that's why i was considering to use the STP OPTION if that's going to work.

No, it should be your first option. Pouring some chemical which is not even recommended by the manufacturer shouldn't even be an option. Towing might be expensive, but the damage caused to the engine by temporary fixes will result in an even more severe expense. If you can't afford to tow, then just ask one of your friends to help you out.

As Rumesh said, you've been running for a long time with the engine burning oil and an intermittent check engine light. You've seen all the warnings, but haven't really done anything about it and are worried when the car doesn't start anymore? Even worse, you're considering a temporary fix? I don't think you understand that the severity of the repair you could be looking at if you continue to go on patching things up without addressing the issue and applying the correct and one-time solution.
