Alright so seriously everything is wrong with this car, it has 193k on it. so I think life is ending on it.

Anyway car now mis-fire a lot, and it get worst everyday, engine light starts flashing. It has code for mass air flow sensor which getting replaced in two days, Can spark plugs make engine completely loose power, it's like not getting any gas anymore.

Gas bump is almost two months old. after the gas pump went bad, everything else started happening, there was oil leak, with heavy oil, it doesnt leak.

Replaced both side cover gaskets, should we replace the head gasket seal also?

Leak was from the passenger side, you could smell oil burning and smoke because it hit the exhaust.

Mechanic said both turbo are shot, which sound strange, he said oil is in them..


Suggestions.

how old are the spark plugs?
if new, I'd suspect coil packs
unplug the MAF, take it for a drive - does it run better?
what MAF code does it show, exactly?
oil could be coming from cam seals - replace those first

after changing spark plugs today, i feel a lot better. Car runs perfect, waiting on MAF anyway thats only code left.

Now oil leak, when putting heavy OIL it doesn't leak does that help

your oil leak could be may of different things such as
(1) Cam Seals and Cam Tensioner gaskets
(2) Valve Cover gaskets
(3) Prop Shaft seal

All of the above would cause an oil burning smell from exhaust

As for Turbo's is there alot of oil in the lower intercooler hoses?? If lots of oil is present possible turbo charger/chargers failure!!

still hard to say where the leak is coming from
might clean up the engine bay completely and see where it drips from, then go from there - still say cam seals, though it could be a bad chain tensioner

clear the MAF code - does it come back?

possibly, but just because there is a lot of oil in the IC hoses, that doesn't mean the turbos are gone
it could mean his PCV system is clogged and needs to be replaced

That was my next step, going to do a full engine bay cleaning, is there a good way to clean the engine.

remove the top engine covers use a pressure washer at your local car wash. just stay away from the any a/c componet minus the compressor. you should be fine. thers is a possiblity it could be the 2 oil return lines for the turbos leaking also.

by hand is still the best way
engine degreaser and elbow grease

quickaudi:STFA

still a bad idea
many an S4 has been pressure washed and killed a component and never started again

at the very least, it'd be good to leave the engine running if you attempt this
